Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
Answer:
x= 64.3
Step-by-step explanation:
To solve for x, you have to use trig. Since you're solving for an angle, you use inverse trig.
the problem gives you your opposite(29) and your adjacent(14), so you will use tangent.
so to set up your equation to type it into your calculator, it will be

type this into your calculator and you will get x.
