Answer:

88%

Step-by-step explanation:

The percentage of a number or fraction can be derived by multiplying the given value by 100%.

Given the fraction 22/25, the percentage of the fraction will be

gotten by multiplying the fraction by 100%

22/25 × 100%

= 22×4

= 88%

Exponential Rule [Powering]: $\displaystyle (b^m)^n = b^{m \cdot n}$

Derivatives

Derivative Notation

Derivative of a constant is 0

Implicit Differentiation

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

eˣ Derivative: $\displaystyle \frac{d}{dx}[e^u] = u'e^u$

Step-by-step explanation:

Step 1: Define

$\displaystyle (e^x)^2 = 7x + 5y + 3$

Step 2: Differentiate

Rewrite [Exponential Rule - Powering]: $\displaystyle e^{2x} = 7x + 5y + 3$
Implicit Differentiation: $\displaystyle \frac{d}{dx}[e^{2x}] = \frac{d}{dx}[7x + 5y + 3]$
[Derivative] eˣ derivative: $\displaystyle 2e^{2x} = \frac{d}{dx}[7x + 5y + 3]$
[Derivative] Basic Power Rule: $\displaystyle 2e^{2x} = 1 \cdot 7x^{1 - 1} + 1 \cdot 5y^{1 - 1}\frac{dy}{dx}$
[Derivative] Simplify: $\displaystyle 2e^{2x} = 7 + 5\frac{dy}{dx}$
[Derivative] [Subtraction Property of Equality] Subtract 7 on both sides: $\displaystyle 2e^{2x} - 7 = 5\frac{dy}{dx}$
[Derivative] [Division Property of Equality] Divide 5 on both sides: $\displaystyle \frac{2e^{2x} - 7}{5} = \frac{dy}{dx}$
[Derivative] Rewrite: $\displaystyle \frac{dy}{dx} = \frac{2e^{2x} - 7}{5}$

Which ordered pair is the vertex of y= |x+5|?

ddd [48]

The vertex for an absolute value equation is the when the expression inside the absolute symbol equals zero.
when x+5=0, x=-5
so the vertex is at (-5,0)

Solve for x. X^ 3 =−216

bagirrra123 [75]

This isn't really a question of math, but rather memorization. I know from memory that this is -6, and -6 * -6 * -6 = -216.
