h(t)=-16t²+192t+2560
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For t=8 seconds
substitute the value of t in the function and find the value of h
h(8)=-16(8)²+192(8)+2560
=3072ft

Answer:
10058
Step-by-step explanation:
The equation is of the form
y = ab^x
Where a is the initial value, y is the final amount and x is the time
y = 6000 b^x
7200 = 6000 b^6
Divide each side by 6000
7200/6000 = b^6
1.2 = b^6
Take the 6th root on each side
1.2 ^ 1/6 = b^6 ^ 1/6
1.030853321 = b
y = 6000 (1.030853321) ^ x
Let x = 17
y = 6000 (1.030853321) ^ 17
y=10057.68696
Rounding to the nearest whole number
y = 10058
