Answer:
The answer is A
If x = 0 then y = 1
Step-by-step explanation:
0 = -16t^2 -60t +54
t = 0.75 seconds
solving by the quadratic equation or graphing calculator or completing the square.
Answer:
The answer to this question should be 28.3
First, we calculate the amplitude
A = (1/2) (xmax - xmin)
A = (1/2) (8 - (-2)) = 5
Since we're given with the period which is pi, then the coefficient of x is just 1. So, the model is
y = 5 sin x
