Kruka [31]

Well since I do not know the unit of measure, I can not give you the answer in a unit of measure but it would be the same answer just add the unit for example meter at the end of the answer and square it.
The answer is:
232.048

Answer:

92.5 centimeters.

Step-by-step explanation:

The one-meter snake showed up as 2 cm in the developed photo. Since there are 100 centimeters in a meter, you subtract the length of the snake in centimeters by the length it shows up in the picture. 100-2 is 88, so that would be the difference. To find the length of the wall, you add the difference to how it showed up in the picture. 88+4.5=92.5.

Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

<u>Step 1: Define</u>

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

<u />

<u>Step 2: Differentiate</u>

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

<u>Step 3: Solve for Rate</u>

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.
