Answer:
The height of ball is 17 ft at t=0.55 and t=1.14.
Step-by-step explanation:
The general projectile motion is defined as

Where, v is initial velocity and y₀ is initial height.
It is given that the initial height is 7 and the initial upward velocity is 27.
Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.

The height of ball is 17 ft. Put h(t)=17.


On solving this equation using graphing calculator we get


Therefore the height of ball is 17 ft at t=0.55 and t=1.14.
Answer:
2.8409091 miles
Step-by-step explanation:
Answer: 46 degrees
Step-by-step explanation:
180 degrees in a triangle and the two 5 sides are congruent, making the other two angles congruent
180 - 88 = 92
92 / 2 = 46
This means a has a value of 24.
