question 31 and 32 Producing each unit does not exceed $3.65. A) Not more than 200, 000 units B) At least 200, 000 units C) At least 100, 000 units D) Not more than 100, 000 units Write an equation that expresses the relationship. Use k as the constant of variation. we varies directly as the square of v. A) w = k/v^2 B) w = kSquarerootv C) w = kv^2 D) w = k/Squarerootv If y varies inversely as x, find the inverse variation equation for the situation. y = 2 when x = 9 A) y = 2/9x B) y = 18/x C) y = 1/18x D) y = x/18

Explanation / Answer

31 ) w varies directly as the square of v

w = kv^2 where k is a constant

Option C

32) y varies inversely as x

Let k be a constant: y = k/x

x = 9 ; y = 2

k = xy = 18

So, relation can be given as y = kx

y = 18/x

Option B
