12.5 cm because the radius is half of the distance imbetween a circle
Answer:
See the attachment
Step-by-step explanation:
A unit circle is one whose radius is 1
sin(90) will have coordinates (0,1)
sin(40)= 0.643
sin(40)= P/H= 0.643/1
cos(40)= B/H= 0.766
Similarly for cos(245)= cos(-65)= -0.423/1
sin(245)= sin(-65)= -0.906

Answer:
1) h(t) = -5(t-3)^2
2) The ball reaches the highest point at 3 seconds.
Step-by-step explanation:
OK. So for this question, I recommend to rewite using vertex form since the answer is given in a more concise manner than using factored.
First Step:
h(t) = -5t^2+30t
= -5(t^2-6t)
= -5(t^2-6t+9)+45
= -5(t-3)^2+45
Second Step:
The vertex form reveals the vertex to be at (3, 45).
Therefore, the ball reaches the highest point at 3 seconds.
