Answer:
13
Step-by-step explanation:
(f∘g)(4) is another way of writing f(g(4)).
First, find g(4).
g(x) = 2x − 3
g(4) = 2(4) − 3
g(4) = 5
Now substitute into f(x).
f(x) = 4x − 7
f(g(4)) = 4g(4) − 7
f(g(4)) = 4(5) − 7
f(g(4)) = 13
Answer:
g=130⁰ k=74⁰ h=50⁰ m= 106⁰
Step-by-step explanation:
They have to add up to 180 and opposites are equal.
I would say the answer is B. 8 1/2 because 11/20 is close to 10/20 which would be the same as 1/2
Answer:
y = - 8
Step-by-step explanation:
The input is x and the output is y
Given
y = 2x ← input the value x = - 4, then
y = 2 × - 4 = - 8 ← output
Answer:
![\boxed{\sf \ \ \ maximum \ is \ 11^9=2357947691 \ \ \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20%5C%20%5C%20%5C%20maximum%20%5C%20is%20%5C%2011%5E9%3D2357947691%20%5C%20%5C%20%5C%20%7D)
Step-by-step explanation:
hello
![y = 11^{(6x-x^2)}=exp((6x-x^2)ln(11))](https://tex.z-dn.net/?f=y%20%3D%2011%5E%7B%286x-x%5E2%29%7D%3Dexp%28%286x-x%5E2%29ln%2811%29%29)
so to know the maximum to y we can check the maximum of
f(x)=![6x-x^2](https://tex.z-dn.net/?f=6x-x%5E2)
f is derivable and f'(x)=6-2x
f'(x)=0 <=> x = 3
so the maximum is reached for x = 3
f(3)=18-9=9
and then
![y = 11^9=2357947691](https://tex.z-dn.net/?f=y%20%3D%2011%5E9%3D2357947691)
to be rigorous, we can write the variation table of y to show that there is only one maximum
hope this helps
