What if we select random primes will it hold?
#help-23
steep yacht
For example, 27 = (17 + 5 + 3) - (terms - 1)
It's weird how it's (p + q) - 1 = Prime. Telescopes outwards
There has to be a some sort of bounds on the number of prime terms used, because the (term - 1) will swallow the tail end of the prime terms
Maybe that could be useful to figuring this out?
safe radishBOT
@steep yacht Has your question been resolved?
steep yacht
Mm You could keep breaking down the primes terms I wonder If some pattern emerges
If you take it to its extreme, all primes would 3*n - (n - 1) = 2n + 1. Because you can keep breaking the primes down in to 3s
Would this be sufficient to prove all primes are (p + q) - 1
<@&286206848099549185>
Does this make any sense?
wait no it doesn't it would imply that (p + q) - 1 = 2n + 1, which would imply that p + q = 2n which is goldbach.
so all primes and (p + q) - 1. then p + q = 2n. because of the recursive nature of the problem

im sure you've taken how to get the domain of a function right?
check if the function is undefined at any points in its domain
if the domain is R then there are no points satisfying the undefined condition
just by looking at it, the domain is gonna be just R because its a normal quadratic function
if you wanna check if the function is equal to zero, just set it to zero and factorize

can you teach me the steps to solve question a
please
stuck on this for 30 minutes
the teacher gave the answer already which is 19.4 but im trying to know how to find it out
obsidian oracle
You know one side, you want to know the other
Compared to the angle you know
What's the side you know?
obsidian oracle
It's not adjacent to the angle
Adjacent = touches the angle
It's opposite
As it doesn't touch the angle
What's the side you want to know?
timid scroll
H is always opposite the right angle triangle
O is always opposite the angel
A is the 3rd one
lunar bolt
soh
lunar bolt
So which formula?
SOH
obsidian oracle
Write down the formula
obsidian oracle
Not ×
sin(31) = 10/a
Opposite/hypothenuse
That's why soh is in this order
Now you can find a
lunar bolt
so is it sin (31) divided by 10??
obsidian oracle
No
lunar bolt
im actually so confused this method worked for other questions but not this one
lunar bolt
How do you put a "on top"?
wdym
lunar bolt
swap it
lunar bolt
wdym by that
lunar bolt
talk a bit more simple please, my brain is a bit foggy today
oh yeah
how do i do that with my equation though
since its only sin 31 and 10
lunar bolt
what do i swap
obsidian oracle
If x/y = c/d, you write y/x = d/c
.
obsidian oracle
Sure
lunar bolt
0.515 is just you plugging in sin(31)
wdym
lunar bolt
oh yeah mb
my calculator was on rad
instead of deg
where does the 1 come from btw?
obsidian oracle
when we swapped
obsidian oracle
a/10 = 1/sin(31)
And then this
lunar bolt
so basically a/10 and =1/sin31
is the same right
@obsidian oracle
okay i got it
thank you

so since the lim as x -> 0 can approach 0 from either the positive or the negative side you have to consider those scenarios
in those scenarios you will see something interesting happen to ln(1+x) and x
just plugging in 0 for x wont always work especially in cases where a numberr is being divided by x

ln(1+x) when x=>0 its equivalent to just x and so ln(1+x)=>x and you get e^2

you can start by counting the total number of possible cases

First, difference can actually be expressed as sum if you change the faces of the second dice: x - y = x + (7 - y) - 7 = x + y' - 7
Then https://mathinsight.org/image/two_dice_distribution has this nice chart, and you just subtract 7 from the sum
Second (minuand) dice: 1 -> 6, 2 -> 5, …, 6 -> 1
For example,
Dice [4] - Dice [5] = Diff [-1]
Dice [4] + Dice' [2] - 7 = -1

probably this will be the procedure to solve, try to make it in summation format ( like using sigma and limit) then take 1/n as common that will be ur dt and by taking 1/n as common, u gonna make x/n that gonna treat as t , then integrate
integration limits would be according to options

These three lines give a figure whose area we need to evaluate
lean ruin
Yes
lean ruin
Looks right to me
lean ruin
Write both functions in terms of x
gaunt nebula
Is it same limits
lean ruin
Yes
Wait actually we made a mistake in the last part
We shouldn't have used upper limit 4
We should have used upper limit = 4 * 8 = 32
gaunt nebula
For part a?
gaunt nebula
Why is it 4x8
lean ruin
Wait no lets redo part a from scratch aight
lean ruin
Yes
lean ruin
Yup
gaunt nebula
Do we need to re establish integrals
lean ruin
I think we can trivially remove the big one on the bottom by integrating x = y yea?
From 0 to 4
lean ruin
No the whole reasoning is flawed there tbh
gaunt nebula
I understand all of it except the upper bound of 1/2
lean ruin
well the line y = 8x and y = 4x intersect where
lean ruin
I added the rectangle from 0 to 1/2
And subtracted the lower area
To get the upper area
We now can subtract that area from our total
This question is much simpler in y btw
lean ruin
Yup put in the limits
gaunt nebula
I got 7
lean ruin
Me too
Now try with y
You can use 0 and 4 and the functions we wrote earlier (y/8 and y)
Just subtract
lean ruin
The other way around im afraid
lean ruin
Because the bigger area is represented by the area under y not y/8
gaunt nebula
Answer is back at 7

@cinder pewter Has your question been resolved?
cinder pewter
Do you know what a continuous function is?
I do but I can’t picture a graph for these definitions
empty gyro
There isn't a specific graph for these, no
It's more about intuitively understanding the definition of continuity
As an example, consider gas prices as a function of time.
Absolutely not continuous. Gas prices can change by an amount at any time, jumping around from any value to any other value
It could be 4.50 one moment, then instantly go to 4.70
It's not continuous because the price has a sudden jump
So, for the first one, can temperature instantaneously jump from one value to the next? Or does it move smoothly?

I would say it’s continuous then
empty gyro
I would agree. Temperatures changes smoothly. It may rapidly change, say if you start a fire. But that change would not be instant
Okay, what about the second one?
cinder pewter
Okay, what about the second one?
The wording is throwing me off
Is it the temperature at a certain time but the distance is different each time?
empty gyro
Basically, it's temperature as a function of your location
cinder pewter
I’d say discontinuous then because the temperature could jump based on the distance
I’ll try the last 3 and let u know cuz I get 3 attempts anyways, ty for the help

I can see how you might think that. Say if there's a hot cup of coffee in a cold room. You may even be right. But more realistically, I would call that a rapid change, but not a sudden jump.
That's hard to say precisely though.
On a large scale, I would argue the temp is continuous

i put down left and down which are correct
cunning cloak
Oh this one
lean otter
but i just dk what im doing wrong for the first fill in blank\
cunning cloak
Could it possibly be right 8 units
cunning cloak
So we know that the left 8 units is correct
lean otter
indeed
cunning cloak
Can u try swapping them out and identifying which part of yoru answer is wrong
lean otter
What other options are there instead of reflect
most of the options are here
compress, stretch, shift, reflect
i think ive tried everyone

What's your question
im just curious as how the fill in the blank is incorrect
left and down are right
but reflect isnt
even if i put shift its incorrect

is there a translate
karmic vine
ask your query
lean otter
ask your query
im just curious what im doing wrong
it goes left 8 units and down 4 units which is correct
so 2/3 is correct
but reflect is wrong
i need help
lean otter
let me figure it out
ok
lean otter
so it shifts left?
lean otter
yes
karmic vine
it is kinda reflecting about the x axis and also shifting towards left
lean otter
hm
i understand what youre saying
just confused on what to put to fill in the blank
karmic vine
try writing both reflects and shifts
lean otter
try writing both reflects and shifts
still marked as incorrect
could it be one of these perhaps
think its just gonna be one word
like compress or something
karmic vine
ohh
lean otter
yea no ones been able to tell me what it is
karmic vine
cant you just consult your teacher?
are you in university?

W = kx * x
k is the spring constant which I thought was found by doing 5/(0.11)^2
but apparently I'm supposed to use some other calculation using the natural length of 32 instead?

do i pick numbers to plug in based on the limit?
safe radishBOT
do i pick numbers to plug in based on the limit?
pure agate
No. 2^- means that x < 2 which means you need to use the first case.
pure agate
You evaluate the limit as x->2^- for f(x). f(x) is determined by if x <=2 or x >2.
For this problem, yes, you can just use x=2.

Can anyone help me how to prove this?
I’m stuck for the (1/m + 1/M)^2
Like I don’t see how it changed to that
Is it I let (mM)^2 then only I can get the term I want?
left gyro
Is it I let (mM)^2 then only I can get the term I want?
if you were more specific on a "letting of a (mM)^2" then itd be correct
what you do is rewrite mM to be inside the square root
(mM) = square root of (mM)^2
this gets moved in to be that (mM)^2 youd need to finish the simplification

spark thicket
A floor plan has a 40: 1 scale. In the drawing, one of the rooms measures 38 inches by 1 1 inches. I need to show my answers to the nearest hundredth, even if it means I need to type zeros. I need to answer the actual dimensions would be # feet by # feet.
The area of the room would be # ft². How should I start to solve this problem?

Is the room actually 38inches by 11 inches or did you mess up the formatting
spark thicket
yeah sorry. That's it.
plucky elk
Or are those the dimensions of the drawing
spark thicket
There is no drawing. That's a word problem.

#, means number

Youre question says there is a drawing: In the drawing, one of the rooms measures 38 inches by 1 1 inches.
spark thicket
no, there is no drawing.

<@&286206848099549185>
plucky elk
Ok, I drew a pic. Now what?
Convert the dimensions to feet then multiply it by the scale to get the room dimensions
1 inch = ? feet
young nexus
1 feet in the map/plan/drawing is 40 feet in reality.
and do not ping every 5-10 minutes.

do I convert 40in to feet?
as well as 38, and 11?
sorry, I still don't get what I am suppose to do? This is a Proportion problem.
plucky elk
as well as 38, and 11?
Yes
spark thicket
38 in is 31.6666667 ft, 11in is 0.91666667, and 40 in is 3.33333. Now what?
plucky elk
38 in is 31.6666667 ft, 11in is 0.91666667, and 40 in is 3.33333. Now what?
No
First one is incorrect
plucky elk
38 inches is not 31.67 feet
plucky elk
Use this
plucky elk
You know the drawing in feet. Then convert that to real dimensions by using the scale
spark thicket
how do I do that?
plucky elk
so i mult 3.33333ft with 3.167 and 0.91666667
No
40:1 does not mean 40 inches to 1 feet
plucky elk
1 feet in drawing implies 40 feet in real dimensions
40:1 means this

bleak delta
you multiplied up and down by x
hardy sphinx
oopsie
bleak delta
yes
bleak delta
yes
bleak delta
multiply 4 both sides
so /4 disappears
cancel out with 4
and the right side is multiplied by 4 also
3(1+x) = 4x-4
3+3x = 4x-4
hardy sphinx
ohhh ok
bleak delta
subtract 3x from both sides
