Suppose i varies jointly with g and v, and j=3 when g=4 and v=3
find the constant of variation

k =

Step-by-step explanation:

Given that j varies jointly with g and v then the equation relating them is

j = kgv ← k is the constant of variation

To find k use the condition j = 3 when g = 4 and v = 3

k = = = =

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
