Answer:
Option C.
Step-by-step explanation:
It is given that the ball's height, in feet, is modeled by the function
where, x represents time in seconds.
We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.
Substitute x=0 in the given function, to find the initial height.
The height of the ball is 3 feet when Sarina throws it.
Therefore, the correct option is C.

Step-by-step explanation:
We have that
y=sin x
for x=2theta
<span>theta = pi/4 radians
so
x=2*pi/4-----> x=pi/2
using a graph tool
see the attached figure
for x=pi/2
y=sin pi/2------> y=1
</span>
the solution is
