The quantity q varies inversely with the square of m and directly with the product of r and x. when q is 2.5, m is 4 and the product of r and x is 8. what is the constant of variation?

5/8
5/4
5
10

 Third option is correct.

Step-by-step explanation:

Since we have given that

The quantity q varies inversely with the square of m and directly with the product fo r and x.

According to question,

Since q=2.5, m=4, rx=8,

So, we put the value of all of theses in our above relation:

Hence, Third option is correct.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
