Question

NEED HELP PLEASE ON THE BOTTOM TWO

Answer 1

(C)

the equation for inverse variation is

w =
`(k)/(l)` ← k is the constant of variation

using the value of k = 164 from part (b), then

w =
`(164)/(l)`

(D)

for l = 3 then

w =
`(164)/(3)` = 54
`(2)/(3)`

for l = 5 then

w =
`(164)/(5)` = 32
`(4)/(5)` = 32.8

for l = 7 then

w =
`(164)/(7)` = 23
`(3)/(7)`

for l = 11 then

w =
`(164)/(11)` = 14
`(10)/(11)`
