ANSWER

Frequency=2

Midline =3

Amplitude =5

Period =π

EXPLANATION

We have:

$f(x) = 5 \cos(x) + 3$

The given function is of the form;

$f(x) = a\cos(bx) + c$

where

a=|5| =5 is the amplitude

and b=2 is the frequency.

and 2π/b=2π/2=π

The range of the given function is

8≤y≤-2

The midline is

$\frac{8 + - 2}{2} = \frac{6}{2} = 3$

Fantom [35]

Answer:

Step-by-step explanation:

They form a straight line so the y sum to 180

52+58+q = 180

Combine like terms

110+q = 180

Subtract 110 from each side

q = 180-180

q = 70
