Answer:
Has your teacher given you notes to practice?
Step-by-step explanation:
If no, then break the question down into pieces and write down what you know.
Answer:
k = 36 and r = 8
Step-by-step explanation:
Given that r varies directly as p and inversely as q² then the equation relating them is
r =
← k is the constant of variation
To find k use the condition r = 27 when p 3 and q = 2, thus
27 =
( multiply both sides by 4 )
108 = 3k ( divide both sides by 3 )
k = 36
r =
← equation of variation
When p = 2 and q = 3, then
r =
=
= 8
They are both decimals, and value in the average place values: .04 is 4 hundred, and .004 is 4 thousand. Also, .04 is 10 times greater than .004.
