aleksley [76]

Road trippin' with my two favorite allies

Fully loaded we got snacks and supplies

It's time to leave this town, it's time to steal away

Let's go get lost anywhere in the U.S.A.

Let's go get lost, let's go get lost...

Blue you sit so pretty west of the one

Sparkle light with yellow icing just a mirror for the sun

These smiling eyes are just a mirror for...

So much has come before those battles lost and won

This life is shining more forever in the sun

Now let us check our heads and let us check the surf

In Big Sur we take some time to linger on

We three…

(csc x - 1) (csc x + 1)
victus00 [196]
<h2>Explanation:</h2>

Here we have the following expression:

(csc x - 1) (csc x + 1)

So we need to extend this. Remember that the difference of squares tells us:

(a-b)(a+b)=a^2-b^2

So here:

a=cscx \\ \\ b=1

Thus:

(csc x - 1) (csc x + 1)=csc^2x-1 \\ \\ \\ But: \\ \\ cscx=\frac{1}{sinx} \\ \\ \\ Then: \\ \\ csc^2x-1=\frac{1}{sin^2x}-1=\frac{1-sin^2x}{sin^2x}=\frac{cos^2x}{sin^2x}=cot^2x \\ \\ \\ Finally: \\ \\ \boxed{(csc x - 1) (csc x + 1)=cot^2x}

Fifteen percent of an employee's taxable income is collected each paycheck. Before taxes are removed from each paycheck,
aleksklad [387]

Answer:

y = x [1-\frac{15}{100}]

Step-by-step explanation:

If the variable x represents the employee's pay before tax-exempt expenses and taxes are removed and y variable represents the employee's take-home pay after these deductions and if fifteen percent of an employee's taxable income is collected each paycheck, then y is given by

y = x [1-\frac{15}{100}]. (Answer)

For, example, an employee's payment is deducted by $350 at the rate of 15% tax and other deduction.

Therefore, \frac{15x}{100}=350, ⇒ x = $2333.33 is the before tax income of the person.
