The height above the ground in feet of a ball kicked into the air from the balcony of an apartment is –16t2 + 24t + 40, where t is the time in seconds since the ball was kicked. How high above the ground is the balcony?
Answer options:
16 ft
24 ft
32 ft
40 ft
The height of the balcony is, essentially, the height of the ball when after 0 seconds.
This means that the answer is the value when you substitute 0 for t.
