Fvaries jointly as g, h, and j. one set of values is f = 18, g = 4, h=3, j=5. find f when g= 5, h=12,and j=3

f = 27

Step-by-step explanation:

F varies jointly as g, h, and j

f = k* ghj

We know f = 18, g = 4, h=3, j=5.

Substituting these in

18 = k* 4*3*5

18 = k* 60

Divide each side by 60

18/60 = k*60/60

3/20 = k

f = 3/20 *ghj

Now we need to find f when g= 5, h=12,and j=3

f = 3/20 * 5*12*3

f = 27

what statement? is there an image?

thus, the first answer choice, y = sec x, is the correct one
