Question

Translate into an equation: p varies directly with m cubed.

Answer 1

\[p(m) ^{3}\]

Answer 2

anything not sure?

Answer 3

i'm not sure

Answer 4

i have another question. y varies inversely with twice the value of x. When y=8, x=2. Find y when x=8.

Answer 5

y/2x

Answer 6

\[y \alpha \frac{1}{2x}\]
y = k/2x where k is a arbitrary constant.

Substitute y=8, x=2.
8=k/2(2)
8=k/4
k=32

Thus the equation is y= 32/2x=16x

when x=8,
y=16(8) =128

Answer 7

Anw with regards to the question posted originally, p varies directly with m cubed.

p is directly proportional to m^3

\[(p) \alpha (m ^{3})\]
p=km^3, where k is an arbitrary constant.

Answer 8

so what you're saying is i have to place the km^3 = p?

Answer 9

If you want to translate into an equation: p varies directly with m cubed.

U will get p=km^3, where k is an arbitrary constant.
