a=3x and b=5y
what happens to 30xy
manic quail
just multiply the right side and then you get the left, @neat ruin
well, 2ab must be 30xy, @alpine sable
alpine sable
well, 2*a*b must be 30xy, <@456226577798135808>
so it becomes 15?
manic quail
no, it is 30xy
alpine sable
30xy
manic quail
30xy doesn't become anything. We are just trying to identify our "a" and our "b" so that we can use the formula.

"translation 5 units left" means like shifted to the left by 5 units, right?
Then it should be $\log_2({-x+5})$, I think, @stuck delta .

olive warren
howdy! I have a relatively simple question about simplifying radicals. my textbook gave me this example -
i'm a bit confused as to how that simplifies to 10sqrt(101)
manic quail
give me 2 min to type it out, @olive warren
manic quail
just lift 10^2 out
olive warren
exactly
manic quail
ahh, great, then I don't have to type it xD
olive warren
makes sense now since it becomes 100(101) and then sqrt of 100 is 10
manic quail
yes, exactly

Can someone help me with this

@manic quail

@tidal patrol Just solve for x, there are multiple ways to do it

If i find X what do i do next?
manic quail
@tidal patrol m=x
manic quail
only if x is an integer though
frail wasp
manic quail
@tidal patrol remove the fractions by multiplying by the denominator
tidal patrol
i got -15/8

@storm spoke technically you are right anyway, because a cirlce is also just a special kind of ellipse

is this correct? I think that the statement is false because of the Congruent Corresponding Chords Theorem
the Congruent Corresponding Chords theorem is:
In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent
We know that AB and CD are congruent chords since ABCD is a rectangle, but we do not know if circles P and Q are congruent circles

I am somewhat new to proofs and am confused by a proof in a real analysis text book. The textbook is "understanding analysis" by Stephen Abbott. In the book theorem 1.2.6 goes as follows: Two real numbers a and b (real numbers) are equal if and only if for every real number e > 0 it follows that |a - b| < e.
In the textbook he proves it in two parts. The first being simple. That is if a = b then |a - b| = 0. Such that |a - b| = 0 < e which is true since all e numbers are greater than 0
The second part of the proof is what confuses me. He shows a proof for (for all e > 0 => |a - b| < e) => a = b. He proves by contradiction such that a =/= b. Then says let e0 = |a - b| > 0. Then a contradiction is formed such that |a - b| < e0 since e0 = |a - b|. Even if this is correct I do not see how this proof by contradiction satisfies => a =/= b being a contradiction
if (for all e > 0 => |a - b| < e) is a contradiction that would seem to imply (for all e > 0 => |a - b| < e) => a = b is a tautology. Since F => T = T. All this seems to indicate is that the LHS of the implication is a contradiction such that modus ponens cannot be applied. But I do not see how this would then cause us to include that a = b?

Here's what I'll do. Let $m_1$ and $m_2$ be the slopes of $y_1$ and $y_2$ respectively.
Now find where $y_1$ and $y_2$ are equal. That is, when [m_1x+30=m_2x.]
With some quick algebra, we see that [x=\frac{30}{m_2-m_1}.]
Now plug in the $m_1$ and $m_2$ and see if your answer matches.

@ripe turret your x value is extremely close to being correct.
ripe turret
@coral pagoda oh my x value is wrong?
coral pagoda
Never round until the end lad
coral pagoda
That's why I waited until the end to deal with the messy arithmetic
coral pagoda
You saw my process
ripe turret
i dont get it
how does our answer match
if we plug both m1 m2
in the 2nd equation
ripe turret

ocean sealBOT
ripe turret
,w {17165875/493267} + 30
ocean sealBOT
coral pagoda
That does not help with the problem at all
coral pagoda
No, I said plug in the slopes m_1 and m_2 in to the final result I have for x
$x=\frac{30}{m_2-m_1}$
ocean sealBOT
117726
coral pagoda
As did I
ocean sealBOT
117726
coral pagoda
What do you end up getting

I have no idea what you did wrong with your arithmetic
I didn't try to plug in the messy stuff to avoid that problem
ripe turret

ocean sealBOT
coral pagoda
You flipped the order
ripe turret
,w 30/{4789/77250}

ok
coral pagoda
Now a good thing to check is that the y-values are indeed the same.
coral pagoda
There's no reason they shouldn't be, but it's good to get in the habit of it
ripe turret
it would be negative
coral pagoda
There is no reason it should be negative
coral pagoda
Here, try this. Instead of trying to figure out what happened with your arithmetic, try to see if you can prove me wrong.
coral pagoda
Ah, that does it :p
It's good to simplify the problem like I did to not accidentally plug in the wrong values.
The less arithmetic you have to do, the better
ripe turret
,w {67/500}*{2317500/4789}
ocean sealBOT
ripe turret
that is y?
coral pagoda
I mean, just find what it is in decimal form
ripe turret
my calc doesnt fit it
coral pagoda
Not sure what you mean
coral pagoda
Well, 64.8455 when rounded
But yes
And that sounds like a pretty realistic number
ripe turret
answer would be 483.92 km right
coral pagoda
What does x and y represent
coral pagoda
Well, then yeah.
coral pagoda
What map question?
ocean sealBOT
coral pagoda
Yea. Any location less than 483 km should have the car ride cost less than a plane trip to the same location
ripe turret
@coral pagoda ok wait 1 sec
coral pagoda
Because the owner wanted our names to all be contained in π 😆
Not quite, but you have the right line of thinking
There ya go!
Nah, likely just gonna be for a day
coral pagoda
Where is your starting point?
ripe turret
from my city
coral pagoda
Okay. Draw a circle where the city is the center and the radius is 483 km
ripe turret
so we draw a circle on the location of were we started
coral pagoda
Yes indeed
coral pagoda
As long as it's to scale, sure
ripe turret
do we need to do that?
ripe turret
ok idrc about where it is at this point
so that and we draw a really big circle with the radius of 483 on each side
how tf we do that
@coral pagoda
coral pagoda
How do you think?
ripe turret
idk
coral pagoda
I think you do. And if not, you can look up a tutorial on youtube
coral pagoda
Depends on if that's okay with your teacher. 🤷
coral pagoda
Yea, you have a scale.
I am not saying that is the actual scale here, I do not know what it is for your map
ripe turret
@coral pagoda it doesnt allow you to show a scale
how tf would you do it
do i just print it and copy it ?
coral pagoda
No, just be mindful of the scale.
Email your teacher to see if the digital circle is good enough
ripe turret
i did

@rapid olive you can find angle A by knowing that the sum of al angles in the triangle is 180
you are given a right triangle and a known angle B = 52,7 degrees
after that use trig to find one more side or hypothenuse, and after that pythagorean theorem for the remaining thing
limber sigil
Well fuck me side ways

exactly what they stated.
factor out (x+3)

Okey i mean i know what factoring is
I mean what i will do is it will equal

Dont you multiply them by the number outside the parentheses
gray isle
if the end goal is to factorise, you don't need to
neat ruin
What is confusing me how the +3 did become -1 and where did the x on the left desspier

If 30 percent = 15 how can i find how much 100 percent is = to
Cant you take 15 x 100/30 to get 50?
neat ruin
Oh yeah that make sense
Tho i did find a way. From internet
Tho thanks
15/3 = 5
5 x 10 = 50
100% = 50

Lol this is supposed to be an easier chapter btw
alpine sable
Yea just find angle ACB by ASP of a triangle and add the three angles which should be equal to 180 degrees since they lie on a straight line so you can find y
trail isle
Wait
alpine sable
I think x is 5 not 15
trail isle
I thought of this but the thing is they didnt say it's a straight line so i cant assume that i think

Hmm

If 30 percent = 15 how can i find how much 100 percent is = to
100% of something=something

Calculate one of the acute angles of the right-angled triangles using either cosine or sine. Find here
the second acute angle by utilizing that the sum of the angles in a triangle is 180 °.
So, for triangle ABC, I did this:
A= Cos(A) = 2/2,24
A = Cos^-1(0,89)
A = 27,13
Idk if it's correct though
gray isle
bad notation with the ** A =** Cos(A)
also lowercase c for cos

i just said
bad notation with the A = Cos(A)

native dirge
just explain why you chose the value and why the other value is not viable
aight
alpine sable
absolute value of n is less than 3
Wait so that would mean that the lowest number would be negative infinite?

no
The absolute value of x, otherwise written as $|x|$, is defined as $|x|=x$ if $x\geq 0$ and $|x|=-x$ if $x<0$

upbeat gorge
So |0| =0, |1|=1, |-1|=1
upbeat gorge
Im confused
Hi confused
upbeat gorge
Wait that would be 1?
Yes
alpine sable
Oh ok
upbeat gorge
So in this case if |x|<3 then x must be between -3 and 3, EXCLUSIVE
Meaning -3 and 3 themselves don’t count
upbeat gorge
Meaning -3 and 3 themselves don’t count
.
upbeat gorge
You have to write it as -3<x<3
Because decimals, fractions, and irrationals exist
Too many real numbers fit in that interval

Kristian vil købe en cykel for 4.995 kr. Han har ikke pengene, men han kan enten låne dem af sin storesøster, som skal have 10% i rente, når han betaler pengene tilbage, eller hos cykelhandleren. Hos cykelhandleren skal han give 1.500 kr. i udbetaling og derefter betale 350 kr. om måneden i 12 måneder. Hvilket lånetilbud er det billigste?
jeg skal også have udregningen af det der.
Mange tak hvis du kan hjælpe mig
jeg er rigtig dum i matematik loL
Ja samme her
Hvilken klasse går du i?
Ved cykelhandleren er det 1500 + 350 * 12 = 5700 kroner
Renformlen er K_n = K_0 * (1 + r)^n
jeg går i 7 klasse
4995 * (1 + 0,10)^1
Tror det er sådan
Cykelhandleren = 1500 + 350 * 12 = 5700 kroner
Hos storesøsteren = 4995 * (1 + 0,10)^1 = 5494.5 kroner
men
hvad er
(1 + 0,10)^1
loLLL
wtf
K_n er resultatet, K_0 er startværdien, r er stigningen pr. år (i decimaler; altså bliver 2% til 0,02), og n er antallet af år der går.
Hos storesøsteren er lånetilbuddet det billigste
kan du ikke bare give mig en anden udregning istedet for (1 + 0,10)^1
pls
det er confusing.
Det er formlen for udregning af renter
Der er ikke andre

Wait, you can borrow money from bicycle dealers in Denmark?
Fierce competition for Danish banks

Weird init
gray gorge
However
The question poses it as if you're paying the dealer in separate installments
Which is something decisively different from borrowing money due to the (seeming?) lack of interest
alpine sable
I think the problem is that he doesn't understand the interest rate formula

can you apply the divergence theorem to a surface integral along a surface which doesn't encompass a volume, like for example a hemisphere?

Fermat's last theorem: Are a and b allowed to be the same?

sullen nova
Hello
Direct: He said to me, “You are not a genius.”
Indirect: He told me that I am not a genius.
Why not He told me that I was not a genius?
<@&286206848099549185>
alpine sable
Because you never use two past tense verbs together
For example, my dad used to DRINK not my dad used to drank
Although he told me that I was not a genius is used very commonly and is acceptable in daily life
sullen nova
I thought simple present tense is changed simple past tense in indirect speech
alpine sable
Yes but this is part of the dialogue
sullen nova
What is the dialogue?
alpine sable
“You are not a genius”
Only the tense of when the dialogue is said is changed
The dialogue remains untouched in terms of tense
sullen nova
But this
Direct: He said, “I am a Cash of Clans player.” (present indefinite)
Indirect: He said that he was a Cash of Clans player.” (changes to past indefinite)
This one changes the tense
And not the first example?
alpine sable
No actually I think the first example should be he told me that I was not a genius
I mixed up the rules the dialogues change too
Like he said “I am going” changes to he said that he was going

Hello I would like some help on my homework i am working on functions and i dont really understand what a function is may somebody please explain?
earnest panther
Functions are mathematical objects that take an input, or several inputs, and give an output based on the input given, often performing mathematical operations on the input.
For example, the function:
f(x) = x + 5
is a function that has one input: x, and gives an output which is the input plus 5.
For example, if you take 2 as an input, the output is:
f(2) = 2 + 5 = 7.
(The output is 7.)
hushed hill
ok thank you
how would i go ab solving this
Which of the sets of ordered pairs represents a function?
A = {(−4, 5), (1, −1), (2, −2), (2, 3)}
B = {(2, 2), (3, −2), (9, 3), (9, −3)}
acc nvm i think i got it
alpine sable
None right?
Cos the same input has two outputs
And a relation is a function only when every input has a unique output

Calculate both the missing side lengths in both triangles with cos or sin.
I did this for the side a
sin(56,31) = 3,61/x
x * sin(56,31) = 3,61
x = 3,61/sin(56,31)
a = 4,33
But it seems incorrect as the hypotenuse is always the biggest side

help?

<@&286206848099549185>

Yo, so my assignment is I have to find the missing sides...
I'm trying to find start off by finding the side a and using sin for that. The formula to find the side a with sin is:
c * sin(V) = a
The problem is that there isn't a number for the side c, what do I do here?
austere pagoda
uhh idk wdym
austere pagoda
idk all i know is that if u have all 3 angles
alpine sable
c is always the longest side
austere pagoda
u can find all the sides
alpine sable
how
alpine sable
hm
austere pagoda
law of sines
alpine sable
3.00
austere pagoda
okay yea
alpine sable
But now c
alpine sable
we use sin
again
well we have to find
either b or a
well acc a
so sin and a
austere pagoda
8u already have a
isnt there a formula where u take thea angle over the side
becuase u have eveything u need
im pretty sure theres a formula
i just dont know what ur cirriculum is
alpine sable
wait
no
thats incorrect
hold up
the problem is there aint a formula to find the side b with s
alpine sable
bro i dont think u know how this works
austere pagoda
okay well how was i supposed to kn-ow u switched it
alpine sable
<@&286206848099549185>
austere pagoda
why are u switcing the sides
austere pagoda
his writing or what was there

what was there
austere pagoda
lmfao
lost steeple
What do you need help with
austere pagoda
thats what i was saying
alpine sable
F
lost steeple
What are you trying to do\
alpine sable
lost steeple
remember triangle 180 - 56.31 - 90
lost steeple
ye
lost steeple
Then you the sine law
The ratio between anggle to side should be the same in sine law
so sin(B) / b = sin(A) / a = sin(C) / c
which means sin(90) / 3,61 = sin(56,31) / a = sin(C) / c
so actually you don't even need angle c
sin(90) / 3,61 = sin(56,31) / a
alpine sable
ok listen up
alpine sable
So I started finding side a (listed the side in the pic to clear up confusion)
I used the sin relation, which you have to do in this case. So I did:
3,61 * sin(56,31) = 3 = side a
However, now it got confusing, because I have to find side b, and I have side a and c right now, so what do I do now?
alpine sable
no
lost steeple
you said you found side a
alpine sable
it's like this,
lost steeple
I think your labeling may not be to the diaggram
alpine sable
I need to find b
lost steeple
why not keep the same labelingg
lost steeple
that's not true but ok we can work with that
so you have side c and a
you can solve for b using either sine law
alpine sable
ion think we have to use Pythagorean here as that's not what the assignment says
lost steeple
Well it's a valid option but if it restricts you from doing that then
Use the sine law
alpine sable
The rules of finding side b
c * cos(V) = b
a / tan(V) = b
well, i dont see sin here
lost steeple
sin(56,31) / b = sin(90) / 3,61
alpine sable
so thats not true
lost steeple
You have to realize the variable could be anything
just because you don't see b doesn't mean it doesn't work
lost steeple
alpine sable
The side a
c * sin(V) = a
b * tan(V) = a
The side b
c * cos(V) = b
a / tan(V) = b
The side c
a / sin(V) = c
b / cos(V) = c
lost steeple
Actually if you want just plug the known sides into a triangle calculator
alpine sable
U don't have to show me whether to use which one
lost steeple
just a question is that 5631 or 56.31
Well those are the answers, if you did the sine law like I said you'd also get thhe same answer
alpine sable
brb
lost steeple
sin(33.69) / a = sin(90) / 3.61
sin(33.69) = 0.27700831a
0.554699216 = 0.27700831a
a = 2.00246417
same as the calculator showed

Hi is this available
But I don’t know what those parallel lines create
I think it’s congruent with AA

frank elk
help ping
rigid smelt
<@&286206848099549185>
Please ping after and minimum of 15min
And the parallel lines create similar triangles
rigid smelt
Which gives you a very famous identity known as thales theorem, which states Ad/AB = AE/AC = DE/BC
rigid smelt
Sure, im just letting you know
alpine sable
But what does it similar with AA
Like I know one is reflexive
But the other is I don’t know
What does the parallel line create
gray isle
seems you know some terms related to parallel lines.
if you don't know which one to apply here, reread the definition
alpine sable
Where should I draw correspondin angles
alpine sable
seems you know some terms related to parallel lines.
if you don't know which one...
I’ve tried but there’s not really an angle I think I could draw ;c
gray isle
there should be nice diagrams showing those types of angles
and it should be clear what you have when comparing them to what you have in the question
alpine sable
Should I put the corresponding angles on
E and C
Parallel lines is the only thing I don’t get about this topic
alpine sable
I don’t know bro pls help
alpine sable
No that’s not it
gray isle
are you familiar with the 3 point labelling system?
gray isle
to unambiguously label angles
alpine sable
Notice how they both share same angle name A
That’s the reflexive one
But I don’t know the other congruent angles they have that makes them similar
I only need one more and I’m done with this question
gray isle
should I put the corresponding angles on
E and C
be more clear about which angle at E you mean
rigid smelt
I can assure you there are two
gray isle
theres a point E,
and at E there are multiple angles
alpine sable
theres a point E,
and at E there are multiple angles
Do you know the answer bro?
gray isle
yes
alpine sable
Bro then pls tell me
gray isle
we've been trying to lead you to what you need to do
gray isle
we've implied that corresponding would be appropriate here however
theres a point E,
and at E there are multiple angles
Name them appropriately to not confuse anyone
are you familiar with the 3 point labelling system?
gray isle
taking this to a ridiculous level. if you just say angle Z, noone will know which angle you're refering to
just like in this case, if you say angle E, we have nfi which angle you're referring to
alpine sable
Bro give me the answer and tell me the lesson after
sick palm
not give u the answer. if you cant understand the problem. learn the basics of it.
rigid smelt
Pretty sure you wont understand it with the answer
gray isle
sick palm
idk how u can ever get help then bub
gray isle
so much shit around E
alpine sable
