Answer:

25

Step-by-step explanation:

Area is the square of the side length, so

s^2 = 25^2

Matching parts of this expression, we see ...

s = 25

The length of each side is 25.

<span>To find her take home pay, you subtract her deductions from her gross pay and then divide her take-home pay by her gross pay and then multiply by 100%.

It is given that y varies inversely as x^2. If x is decreased by 50%, find the percentage change in y.

vova2212 [387]

Answer:

300%

Step-by-step explanation:

Given

$y\ \alpha\ \frac{1}{x^2}$

Required

Find the percentage change in y when x decreased by 50%

First, convert to equation

$y\ = \ \frac{k}{x^2}$

Where k is the constant of proportionality

When x decreased by 50%

$Y = \frac{k}{(x - 0.5x)^2}$

$Y = \frac{k}{(0.5x)^2}$

$Y = \frac{k}{0.25x^2}$

Expand

$Y = \frac{1}{0.25} * \frac{k}{x^2}$

Substitute $\frac{k}{x^2}$ for y

$Y = \frac{1}{0.25} * y$

$Y = 4 * y$

$Y = 4 y$

The percentage change is then calculated as:

$\%Change = \frac{Y - y}{y} * 100\%$

$\%Change = \frac{4y - y}{y} * 100\%$

$\%Change = \frac{3y}{y} * 100\%$

$\%Change = 3 * 100\%$

$\%Change = 300\%$

<em>The percentage in y is 300%</em>

Factor fully. Solutions should be in the form Factor 1: (4x-3) Factor 2: (x-4)

My name is Ann [436]

Answer:

5x² − 37x - 24 =
5x² + 3x - 40x - 24 =
x(5x + 3) - 8(5x + 3) =
(5x + 3)(x - 8)

<u>The factors are:</u>

Factor 1: 5x + 3
Factor 2: x - 8
