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

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

6 possible ways to order 3 couples in a row

Given,

We have three married couples. that is six persons in total.

a, b, c, d, e, f may taken as the six persons.

Considering the statement:

Elder partner on the left, assume a, c and e as elders.

Then we have, (a, b) ------ ( 1)

(c, d) ------ (2)

(e, f) ------ (3)

There is no change in position between the couples.

So, we get three persons in total.

Possible ways to order these three persons will be like this: 3! = 3×2×1

= 6

Which represents the reflection of f(x)=sqrt x over the y axis

zloy xaker [14]

reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be $g(x)= f(-x)$

So, finding reflection of $f(x)=\sqrt{x}$ over the y axis we get:

$g(x)=\sqrt{-x}$

So, reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$
