Answer:
B) 5
Step-by-step explanation:
Divide the volume by the formula and you get that 1000=r^3. r is 10, but every second it gains 2 cm, so divide 10 by 2 to get 5
Domain - all real numbers except 0
Range - all real numbers
The function will be undefined if x = 0, but apart from that, the function can take any value
from question d = 16t^2 = 56-4t
=》 16t^2 -56 + 4t =0
=》 4t^2 - 14 + t = 0
=》 (4t-7)(t+2) =0
=》 t = 1.75 seconds
