Answer:

<h2><em><u>B. (-1/2)^-3</u></em></h2>

Step-by-step explanation:

B is the answer. This is because you have to calculate (-1/2)^-3 on a calculator. When I did that calculation, I got -8.

(-1/2)^-3      =    (-2)^3 = -2*-2*-2 = 4 * -2 =<em><u> -8</u></em>

Hope this helped,

Answer:

 a.  y^ -1 = e^x    +2

Step-by-step explanation:

y = ln (x-2)

Exchange x and y

x = ln (y-2)

Solve for y

Raise each side with a base of e

e^ x = e^(ln(y-2)

e^x = y-2

Add 2 to each side

e^x  +2 =y

kondor19780726 [428]

Step-by-step explanation:

Consider the provided information.

For the proportion method first set up the equation like this:

\frac{Part}{Whole}=\frac{Percentage}{100}

Perform the cross multiplication and then solve for the missing part.

For example:

Find 80 percentage of 10.

Step 1: Set up the equation.

\frac{Part}{10}=\frac{80}{100}

\frac{Part}{10}=\frac{4}{5}

Step 2: Perform the cross multiplication

Part=\frac{4}{5}\times 10

Step 3: Solve for the missing part.

Part=4 \times 2

Part=8
