Answer:
what
Step-by-step explanation:
Answer:
A) 16
Step-by-step explanation:
The question is:
Evaluate the expression using the given value of the variable.
when 
A) 16
B) -24
C) -18
D) 28
Solution:
Given expression:

Plugging in
in the expression
⇒ 
⇒ 
⇒ 
So the expression evaluates to 16 when we put 
x = A cos ω t
where,
A is the amplitude
ω is the angular frequency
Since the shape is a circle, therefore the amplitude is
simply equal to 2π or 6.28 rad while the angular frequency is 5 rad/s, therefore:
x = 2π cos 5 t
Make the denominators the same and then multiply the numerators and then add the fractions together . You should get 29/24
I believe the answer should be -60. But I could be wrong. I tried though...
