AAAH HELP! Assume that r varies directly as p. What is the constant of proportionality if r = 3 when p = 15. k = 1\5 k = 5 k = 3 k = 45

Sagot :

Answer:

k = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Given that r varies directly as p then the equation relating them is

r = kp ← k is the constant of variation

To find k use the condition r = 3 when p = 15, then

3 = 15k ( divide both sides by 15 )

[tex]\frac{3}{15}[/tex] = k , that is

k = [tex]\frac{1}{5}[/tex]

Answer:

k = 1/5
