It will reach 80 feet for the second time after 5 seconds.
We set the equation equal to 80 feet:
80= -16t² + 96t
When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80
We use the quadratic formula to solve:

Answer:
63,990 mi²
Step-by-step explanation:
We can find the answer by using the formula for the area of a trapezoid and putting in the given numbers.
A = (1/2)(b1 +b2)h . . . . where b1, b2 are the base lengths; h is the height
A = (1/2)(198 mi +276 mi)(270 mi)
A = 63,990 mi²
