The height h above ground in feet of a ball dropped from the top of a 30 foot tall building after t seconds is given by the polynomial: h(t)= -16t^2+30. what is the height of the ball after 1/2 second?
h(t)= -16t^2+30
--
Sub 1/2 for t to find h(1/2)

= 28/4 - 19/4 = 9/4
Answer is 2 1/4 or 2.25.
Hello!
As we are looking for the opposite side and hypotenuse, we will use the sine.
sin30=1/2
This gives us the equation below.
1/2= 5/x
1/2x=5
x=10
Therefore, x=10.
I hope this helps!
