Question

PPPPLLEASE!!! URGEEEENTT!! THNX
M is directly proportional to L^3
When L=2, M=160
Find the value of M when L=3

Answer 1

please answer!!

Answer 2

M is directly proportional to L^3

translates to

M = k*L^3

where k is some fixed number

Answer 3

we are given When L=2, M=160

so plug this in to get

M = k*L^3

160 = k*2^3

and solve for k

tell me what you get

Answer 4

is the final answer 540?

Answer 5

yes you should have gotten k = 20, so

M = 20*L^3

when L = 3, we get

M = 20*L^3

M = 20*3^3

M = 20*27

M = 540
