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.

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4, identify (f + g)(x).

shutvik [7]

Answer:

(f + g)(x) = x^2 + 3x - 6

Step-by-step explanation:

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4

Plug in:

(f + g)(x) = x^2 + x − 2 + 2x − 4

(f + g)(x) = x^2 + 3x - 6

Your customer is located 100 miles from your office.

OlgaM077 [116]

Answer:

8:02 AM

Step-by-step explanation:

Find out how many minutes it takes to travel one mile:

60 divided by 45= 1.333334 minutes

It takes 1.333334 minutes to travel 1 mile, how long will it take to travel 100 miles:

1.333 times 100 = 133.3334

133.3334 rounds to 133 minutes

Add 15 minutes because you want to arrive early

133+15=148

Divide it by 60

148 divided by 60 = 2.466667

or do

148-120 (2 hours) = 28 minutes

It will take 2 hours and 28 minutes to get there

10:30-2:28= 8:02
