Question

If m varies directly as the square root of y, inversely as p^2, and directly as n, what happens to m when y is quadrupled, p is tripled, and n is multiplied by 5?

Answer 1

Answer choices:

Answer 2

so... m = k y^0.5 p^-2 n?
do this:
m'=k (4y)^0.5 (3p)^-2 5n

Answer 3

@RichGrl20 does that help?

Answer 4

@Peter14 : Yes, it does! Thanks. :D

Answer 5

glad to help. anything else?

Answer 6

@Peter14 : Um... I'm not too sure how to figure out what happens to m. I know that each equation models what is said in the description, but I don't know how to use those to find out what change is applied to m, if any.

Answer 7

apply the exponents to the numbers I put in

Answer 8

just ignore k

Answer 9

here, there's an easier way. go back to the first equation I made, except leave out the k

Answer 10

m=y^0.5 p^-2 n
plug in a 1 for each of those numbers.
then go back and change each number as specified in the description of the problem at the top

Answer 12

I may have done it wrong, but I'm not getting any of the answer choices...

Answer 13

set it up for me

Answer 14

@RichGrl20 it is one of the answer choices, do it here so I can see where you made a mistake

Answer 15
