Answer:
10 seconds
Step-by-step explanation:
we are given the height (s) which is 1600ft. and the formula—where t is time in seconds— t= 1/4
, so we can plug 1600ft in for s and solve:
t= 1/4
t= 1/4(40)
t= 10 seconds
If the function is f(x) = 6(0.4)x then the domain is ALL REAL NUMBERS and the range is ALL REAL NUMBERS!
