F=1/2kp, solve for k

Norma-Jean [14]

F = 1/2kp....multiply both sides by 2, eliminating the 1/2
2F = kp...now divide both sides by p
(2F/p) = k

A lumber company needs to estimate the volume of wood a load of timber will produce. The supervisor knows that the volume of woo

Hitman42 [59]

Answer with Step-by-step explanation:

Let the volume be represented by 'V'

Since it is given that Volume varies with height 'h' and square of the girth 'g' we can write

$V=khg^2$ where 'k' is a constant of proportionality

Now it is given that volume is 288 cubic meters for h= 40 meters and g =1.5 meters we can write

$288=k\times 40\times 1.5^2\\\\\therefore k=\frac{288}{40\times 1.5^{2}}=3.2$

Thus the volume of the timber as a relation is

$V=3.2\times hg^{2}$

Part b)

Volume of 50 trees with height 75 meters and girth 2 meters is

$V=50\times 3.2\times 75\times 2^{2}\\\\\therefore V=48000m^{3}$
