Just add up all the numbers and divide by 6, as there are six numbers in this set of numbers
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
The answer is 30
You multiply 2 x 30 which is 60 and 60 + 30 = 90
hope this helps :D
Answer:
Janet collected 3.48 bags of cans
Step-by-step explanation:
The answer is 3.48 because 0.87 multiplied by 4 is 3.48
<span>Simplifying
u(x) = -2 + -2x + 7
Multiply u * x
ux = -2 + -2x + 7
Reorder the terms:
ux = -2 + 7 + -2x
Combine like terms: -2 + 7 = 5
ux = 5 + -2x
Solving
ux = 5 + -2x
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Divide each side by 'x'.
u = 5x-1 + -2
Simplifying
u = 5x-1 + -2
Reorder the terms:
u = -2 + 5x-1</span>
