What percent of $5x$ is equal to $x/5$?

amm1812

Answer:

Step-by-step explanation:

Let y% of 5x is equal to $\frac{x}{5}.$

$y\% \: of \: 5x = \frac{x}{5} \\ \\ \therefore \: \frac{y}{100} \times 5x = \frac{x}{5} \\ \\ \therefore \: y = \frac{x}{5 \times 5x} \times 100 \\ \\ \therefore \: y = \frac{1}{25} \times 100 \\ \\ \therefore \: y = 4 \\ \\ \therefore \: 4\% \: of \: 5x \: is \: equal \: to \: \frac{x}{5}$

1+secA/sec A = sin^2 A / 1-cos A

Fofino [41]

Answer: see proof below

<u>Step-by-step explanation:</u>

$\dfrac{1+\sec A}{\sec A}=\dfrac{\sin^2 A}{1-\cos A}$

Use the following Identities:

sec Ф = 1/cos Ф

cos² Ф + sin² Ф = 1

<u>Proof LHS → RHS</u>

$\text{LHS:}\qquad \qquad \dfrac{1+\sec A}{\sec A}$

$\text{Identity:}\qquad \qquad \dfrac{1+\frac{1}{\cos A}}{\frac{1}{\cos A}}$

$\text{Simplify:}\qquad \qquad \dfrac{\frac{\cos A+1}{\cos A}}{\frac{1}{\cos A}}\\\\\\.\qquad \qquad \qquad =\dfrac{1+\cos A}{1}$

$\text{Multiply:}\qquad \qquad \dfrac{1+\cos A}{1}\cdot \bigg(\dfrac{1-\cos A}{1-\cos A}\bigg)\\\\\\.\qquad \qquad \qquad =\dfrac{1-\cos^2 A}{1-\cos A}$
