Answer:
The answer is 2 seconds.
Step-by-step explanation:
H(t) = -16t² + Initial height
0 = -16t² + 64
-64 = -16t²
4 = t²
t = 2 seconds
Answer is c because it has to be moved
5.
-4=r/20-5
First add 5 to both sides
1=r/20
Then multiply both sides by 20
20=r
Final answer: r=20
7.
(v+9)/3=8
First multiply both sides by 3
v+9= 24
Subtract 9 from both sides
v=15
Final answer: v=15
Answer:
y = sin(x- pi/2)
Step-by-step explanation:
Please see the attached image to see your graphs.
By simple inspection we can see that the sine is shifted pi/2 to the right.
We know this because sines are periodic functions with a period T = 2*pi
We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.
And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.
