Answer:
The answer is C
Step-by-step explanation:
All of the numbers are all different a function is when there are no same numbers
S = 2 * (pi) * r * h.....for r
divide both sides by 2 * pi * h
s / (2(pi)h = r
h(t) = -16t^2 + vt + 5
h(3) = 131 ft
h(3) = -16(3)^2 + 3v + 5 = 131
3v = 270
v = 90 ft/s
Answer:
im not too sure but my best guess would be
D= 900×T
D= the constant of proportionality multiplied by time to get how many miles traveled.
if the hours given were 1 hour 2 hours & 3 hours
if you multiplied them by 900 you would get the distanced traveled
900 x 1 = 900 miles traveled in one hour
900 ×2 = 1800 miles traveled in 2 hours
sounds good ?
