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: this one is confusing
Step-by-step explanation:
Assuming you need to find a multiple of both 3 and 11 to be your answer, the answer should be 33 days.
Answer: 5/12
Step-by-step explanation: To divide one fraction by another, first turn the second fraction upside-down, then multiply.
1/3 ÷ 4/5 = 5/12 ≅ 0.4166667
Ok so
18 - 1 = 17
17 - 2 = 15
15/3 = 5
