Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:

Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
Given:
The equation of line is

To find:
The x and y-intercept of the given line.
Solution:
We have,

Putting x=0, we get

Add 6 on both sides.


Divide both sides by 4.

So, the y-intercept is
.
Putting y=0 in given equation, we get

Add 5 on both sides.


Divide both sides by 7.

So, the x-intercept is
.
Answer:
$20.42
Step-by-step explanation:
Given that:

c=7+a
I'm not 100% sure what you're asking, but i think it wants:
50,000 + 25,000 = 75,000 - so B is the answer
to do it you basically just round the number to the nearest 1000 and add
