16/9 because (3/4)^-2 simplified is 16/9
Answer:
Step-by-step explanation:
(-3/4)^-4 = (-4/3)^4 = (4/3)^4
Lucas equation for his location is x(t) = 13t.
Alfonso's equation is x(t) = 238 - 21t
If you equate these, you get:
13t = 238 - 21t =>
34t = 238
t = 7
So after seven hours they meet.
Answer:
Option A

height = 20 units
Volume of the cylinder = πr²h
= π (13)² ×20
=3380π cu. units
