f(1)=1×4-1=3,
f(n+1)=f(n)+4,
so .... you know.
Answer: g(0) = 2
Step-by-step explanation:
g(x)=3x+2
g(0)=3(0)+2
=2
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
Answer:
B
Step-by-step explanation:
V = 4/3 * radius^3 * pi = 4/3 * 4^3 * pi = 256 /3 * pi
Distribute through the parenthesis
subtract 5 from both sides
divide both sides by -1/3...or multiply both sides by -3
