$\frac{\frac{3}{8}}{\frac{1}{2}}=\ \ \ \ | multiply\ first\ fraction\ by\ inverse\ of\ the\ second\\\\
\frac{3}{8}*\frac{2}{1}=\frac{6}{8}=\frac{3}{4}\\\\
Solution \ is\ \frac{3}{4}.$

Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$l = 30 \ cm\\w = l\\\frac{dl}{dt} = 2 \ cm/h\\h = 20 \ cm\\\frac{dh}{dt} = 3 \ cm/h$

Step 2: Differentiate

Rewrite [VRP]: $V = l^2h$
Differentiate [Basic Power Rule]: $\frac{dV}{dt} = 2l\frac{dl}{dt} \frac{dh}{dt}$

Step 3: Solve for Rate

Substitute: $\frac{dV}{dt} = 2(30 \ cm)(2 \ cm/h)(3 \ cm/h)$
Multiply: $\frac{dV}{dt} = 360 \ cm^3/h$

Here this tells us that our volume is decreasing (ice melting) at a rate of 360 cm³ per hour.

The fencing William chooses costs $29.53 per foot, including installation. What will the fencing cost? Show your work.

TiliK225 [7]

Answer:

$C = 29.53x$

Step-by-step explanation:

Given

$Unit\ cost = \$29.53$

Required

The cost of fencing (C)

The cost is calculated as:

$C = Unit\ Cost * Perimeter\ of fencing$

Let:

$x \to Perimeter\ of fencing$

So, we have:

$C = Unit\ Cost * x$

$C = 29.53 * x$

$C = 29.53x$

The question cannot be solved further since the dimension of the fence is not given

If you know the dimension, calculate the fence perimeter and substitute the value for x
