Answer:
Step-by-step explanation:
Let the width be X ft
Length = 2x - 40
Total area = 33,600 sq.ft
length * width = 33,600
(2x - 40) * x = 33,600
2x² - 40x -33600 = 0
Answer:
Step-by-step explanation:
* Lets explain how to solve the problem
- We can write a sine as a cosine by translate the sine function to the
left by
-
∵ The value of sin(0 + π/2) = 1
∵ cos(0) = 1
∴ sin(0 + π/2) = cos(0)
∴ If sin(x) translated to the left by , then it will be
cos(x)
∴
- <u><em>Vice versa</em></u>
- We can write a cosine as a sine by translate the cosine function to
the right by
-
∵ The value of cos(0 - π/2) = 0
∵ sin(0) = 0
∴ cos(0 - π/2) = sin(0)
∴ If cos(x) translated to the right by , then it will be
sin(x)
∴

A is the correct answer because the y-intercept is -2 and the slope is 3 because it goes up 3 units.
I am taking the test also. I have not submitted yet but right now i have
24(3)^x-2+2. I think one of the twos should be a six but I am not sure. Hope this helps!
