Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

$\displaystyle y = 3x + 5x$

<u>Step 2: Differentiate</u>

Simplify: $\displaystyle y = 8x$

Bumek [7]

Answer:

The amount of interest, he payed is 30 Ghana Cedis

Step-by-step explanation:

The amount Kwame borrowed from the finance company, P = 300 Ghana Cedis

The amount he repaid in each installment, M = 55 Ghana Cedis

The number of installments with which he repaid the loan, n = 6 installments

The amount of interest, "i", he payed, is given by the following formula;

The amount of interest, he payed, i = M × n - P

Therefore, i = 55 × 6 - 300 = 30

The amount of interest, he payed = i = 30 Ghana Cedis.

A solid plastic ball is a sphere with a radius of 8 inches. How much plastic does it take to make one ball

mihalych1998 [28]

Answer:

2144.66in³

Step-by-step explanation:

Radius = 8 inches.

To determine the amount of sphere to make the ball, we'll have to find its volume.

Volume of a sphere = 4/3 * Πr³

V = 4/3*Πr³

Π = 22/7

V = 4/3 * 22/7 * 8³

V = 2144.66inches³

V = 2144.66in³

The amount of plastic required is 2144.66in³.

Lilit [14]

Answer:

Step-by-step explanation:

The formula of a volume of a cube:

$V=a^3$

a - length of an edge

We have V = 27 in³. Substitute:

$a^3=27\to a=\sqrt[3]{27}\\\\a=3\ in$
