divides the angle in half?
so its equal angles?
if that is the case would this mean CD and DB are the same?

correct!

true..

if that is the case would this mean CD and DB are the same?
it can be but not in all cases..you can't assume this to be true and solve this problem
this can be solved without this
tell me the definition of sin, cos and tan now

sin= o/h cos = a/h tan = o/a

so for #2.
teacher wrote parent graph: y = e^x
and Im just wondering why he wrote it and drew it
why is it important?
jagged vault
Because y = e^x is the exponential function in its purest form without any modifications
So your teacher wrote it to help you visualize the modifactions made in the problem function
lean thorn
a parent function is basically the "base" function of which you do your transformations to.
Same thing with something like y = 3x - 2. Here, y = x is the parent function

that’s what i did i was wondering if there was another way to do it bc it’s 4 marks and all i had to do was use a calculator i’m not sure if there js another way
full grove
Can’t even read this hand writing
right basically i got the x solutions using a graph on a calculator and was wondering if there is a way to solve question B another way because it’s 4 marks?

And ε too

whatever you want them to be used for

Physics? I don't know.

rho is usually density

I know.

who uses u for velocity
lean otter
I don't know. I learned this from some AI stuff.
lean otter
Idk
lilac patio
I dont see any reason for knowing symbols that can be anything
hard crest
that's not even u that's upsilon
and also don't learn physics from the lying machine AI
usually v for velocity, m for mass, ρ (rho) for density
lean otter
Lmao but I like to use these symbols more than the Latin letters to make it look more genius
It's kinda cool tho

Are you sure?

i did,
(2/3)b + b is the same thing as (2/3)b + (3/3)b = (5/3)b since we can the implicit 1 as (3/3)

1 = 3/3

what?
im sorry, im not very experience in math, even at this level😅
lean thorn
$\frac{2}{3}b + b$ is the same thing as $\frac{2}{3}b + \frac{3}{3}b$. Now you combine like terms to get $\frac{2 + 3}{3}b = \frac{5}{3}b$

where did 3/3b come from?
evaluate 3/3
clear gazelle
evaluate 3/3
wdym?
exotic snow
Divide 3 by 3
clear gazelle
evaluate 3/3
can this be applied with any number too? can i use 9/9 instead of 3/3?
exotic snow
yes, any number divided by itself is 1, (as long as the number is not 0)
exotic snow
but why cant i just do b/1+2/3?
Not the same denominator
clear gazelle
Not the same denominator
oh i see, it has to have the same common denominator like 9,6,12...?
exotic snow
Not sure where you're getting examples from
clear gazelle
yes, any number divided by itself is 1, (as long as the number is not 0)
like, does any number as long as it has a same common denominator as 2/3?
exotic snow
the denominator of 2/3 is 3, you add any fraction with a denominator of 3 to it, you can change 2/3 to 4/6 or 6/9 etc, but for the problem it's easiest to leave everything with denominator 3

if you just go with the triangle definition of adj/hyp, it's pretty clear as soon as you draw the triangle

When dividing by Ruffini's method, the following scheme is obtained:

If Y = -A, find the value of D + A + G + E + N + P + R + Y.
A) 2
B) 8
C) 1
D) 4

So do Ruffini
For example D=2
Then 2A=-6 and so on
Keep doing and you'll reach the solution

**most likely to honorable**
Yes
glad pagoda
okay this isnt really a great example but say you own a company and you have some number of employees. say you have a bizarre policy where every christmas you pay every employee 1 dollar for every employee you have. so if you have 100 employees, you pay each of them $100 every christmas. now, say you have 8 departments in your company, each of which has 7 employees, and you want to figure out how much money you are gonna have to spend this christmas
your number of employees is 8 * 7, so you need to pay them each 8 * 7 dollars. therefore your total cost is (8 * 7)^2.
alternatively, you could apply this rule to conclude that you are in total going to owe (7)^2 * (8)^2 dollars
this doesnt make much sense im sorry it isnt a super applicable concept

woven hare
How do you do number 45?
hard crest
f(0)=-1 and f(1)=(10)
so you know that there's a root in between there since the signs are different
take a guess where it might be and evaluate f at that guess
woven hare
Wdym by a root?
f(x)=0?
There’s a point where x=0 according to ivt since it changes sign from - to +
still charm
Yes
Guess
Then refine your guess
Or in fact just use a few iterations of newtons method
woven hare
I guess f(0.2) is valid?

Ruffini is not done like that
D=2 then you have 2A=-6.
Then G-6=1 and 1·A=N. Then E+N=-4 and -4A=R. Finally P+R=Y

lusty spear
Can someone please help me with the following exercise ?
In a box there are 6 red 3 white and 1 black balls, where each individual ball is equally as likely to be picked, so (1/10).
You pick 3 times with putting the picked ball back each time.
Random variables:
Y : number of white picks
X : number of red picks
What is P(Y>X)? meaning the probability that you pick more white than red balls.
I figured I might do something like
P(Y>X) = P(Y-X>0) and then say Z = Y-X and Z(Omega) = {-3,-2,-1, 1, 2, 3}
and now I'd have to determine
P(Z>0) = P(Z=1)+P(Z=2)+P(Z=3) but then again I struggle with determining each of these because I dont really know how to handle those two random variables at once.
I wanna note that in this chapter of the book I use the concept of two random variables at once hasnt been introduced therefore this should be solvable without stuff like
P(Y=3, X=0) .
Thanks for your help !

I am sorry I thought I wrote everything down in my initial post
the probability that one picks more white than red balls
tbh I think they messed something up and put that exercise in the wrong chapter because I see no way of solving this without the knowledge about joined distribution and stuff like that

yes yes I agree. Its just that I dont understand why someone would put this exercise in that chapter then but anyways
quasi bison
i mean come on, even analyzing anything about a 2d6 roll becomes impossible with such a prohibition in place!
i would write out a joint-distribution-table-in-all-but-name for X and Y tbh
then just add up all the probabilities corresponding to cells with Y>X
lusty spear
what exactly does " joint-distribution-table-in-all-but-name" mean ?
I mean I know what a joint distribution table is
but what is in-all-but-name
lusty spear
then just add up all the probabilities corresponding to cells with Y>X
yes I will do that then , thank you very much !!
quasi bison
it just means you do not call it a joint distribution table
so that you do not incur the wrath of your professor for using unauthorized concepts
lusty spear
oh no no dont worry
the exercise is just for myself
thank you very much for your help !!

I think they meant the angle at the top being of 50 degrees measure just like in the cone that you have drawn

Draw a line from the top of the cone to the center of the base circle, you have formed a right triangle where you know one of the acute angles and the hypotenuse
