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
Answer:
1
Step-by-step explanation:
Since the coefficient of x is always double the second number in a squared binomial -> (x-1), -2 is double -1. -1 squared gives you 1.
.25/12 is the scale factor. I hope I helped ^^
