Answer:
B 5 seconds
Step-by-step explanation:
h = 240 + 32t – 16t^2
When is this equation 0
0 = 240 + 32t – 16t^2
Factor out 16
0 = -16(-15-2t+t^2)
= -16(t^2-2t-15)
What 2 numbers multiply to -15 and add to -2
-5*3 = -15
-5+3 =-2
0 = -16(t-5) (t+3)
Using the zero product property
t-5=0 t+3=0
t=5 t=-3
Since time cannot be negative
t=5 seconds
Answer:
218
Step-by-step explanation:
Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,
f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8
f(3) = 5(8) + 3 = 40 + 3 = 43
f(4) = 5(43) + 3 = 215 + 3 = 218
