It is a horizontal contraction by a factor of 2. The period of sin x is 2pi. The period of sin 2x is pi. This means it repeats itself twice as often on a given interval.

the correct answer is B. but how did they get that? help me please?
I work it out like this x+y= -1 and 5x=3y
but the answer I got was 3/5 and 5/3.
where d
i need to know how to simplify this answer...please help me:)-sec²(x) - tan²(x) is equal to 1.Thats a standard identity that would probably be good to memorize.
Heres a derivation using the identity
lets say I were to lift something or person weighing 150 lbs, how much weight would I actually be pushing if they were in a wheelchair or on a moving dolly...any websites to help understand it better
hey heres a few math quest i need to have for test review please help
1.) 2x²-36=x
2.) 5x²+9x=-4
3.) k²-31-2k=-6-3k²-2k
4.) 9n²=4+7n
5.) 8n²+4n-16=-n2
6.) 8n²+7n-15+-7
thank you in advance also we ar
at least one of the shirts will be blue-There is a 4/10 chance the first shirt will be blue.
There is a 6/10 chance the first shirt will not be blue and then a 4/9 chance the second one will be blue.
Please solve (and show as muck work as you can/ explain your reasoning)-
1. Find all values for which the impulses y=2sin^2 x and y=1-sin x meet in the interval 0 deg. is less than or equal to 360 de
show that all solutions of 2y + ty = 2 approach a limit as t--> ∞ and find the limiting value.
Can you please include all the steps and be clear so i can see what is going on?
Thank you so much for y
Q: If 2x + 3y = a and -x + 5y = 6b, express x and y in terms of a and b.
My answer:
x = a/2 - 3y/2
y = 6b/5 + x/5
Rearrange and sub
y = (1/13)a + (12/13)b--> matches answer key
x = (1/2)a - (3/2)y= (

#32 is the problem, A is the answer.-The 7 and 14 get reduced. They have a common factor of 7. So, the 14 becomes a 2 and the 7 becomes a 1. Then, when you d
dx/x(1-ln^2x))^1/2from 1 to e
and
(e^1/x)dx/x^2from 1 to 2-∫dx /x√1 - (ln x)^2] from 1 to e
let ln x = u, when x = 1, u = 0 and when x = e, u = 1
dx/x = du
∫ du /√(1 - u^2)from 0 to 1
= sin^-1(u)

I need step-by-step instructions so I can try and get it. There are suppose to be 4 solutions solving for x.-12x^4+4x^3-108x^2-36x=0
3x^4 + x^3 - 27x² - 9x = 0
x(3x³ + x² - 27x - 9) = 0
x[x²(3x + 1)
