If you are looking for the expanded version, this is it. It is also possible to group either an a from (a^2 + 2b) or a b from (2ab + b^2). Hope this helps!

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider all the information given:

Eddie's pension is based on the average of his last four year's salaries

$\hookrightarrow \text{average } = \text {sum of all salaries} / \text{ number of years}\\ \hookrightarrow \text{average}= 392000 / 4 = 98000$

2. The employer will pay 1.2% of that average for each year he worked

$\hookrightarrow \text{1.2 percent of average} = \frac{1.2}{100} *98000=1176$

3. The employer will therefore pay in total

$\hookrightarrow \text{Total pension} = 1176 * 20 \text{ years} = 23520$

Answer: $23520

Hope that helps!

Find the secant of angle Z A.4/5 B.4/3 C.3/5 D.5/3

Alex73 [517]

Answer:

D 5/3

Step-by-step explanation:

Secθ= Hypotenuse/Adjacent

Secθ=10/6

Simplify: 10/6 -->5/3

Ans: D 5/3

remember your six trigonometric functions:

Sinθ=Opp/Hyp -->Cscθ=Adj/Hyp

Cosθ=Adj/Hyp -->Secθ=Hyp/Adj

Tanθ=Opp/Adj-->Cotθ=Opp?Adj

It is basically the opposite of each other, don't forget when you are at the last step you simplify! never forget. Also working with square roots will be a bit tricky when converting to Csc/ Sec/ Cot. Just noting you that Square roots don't belong in denominators!

Renee is making a scale diagram of her mp3 player. The length of her scale drawing is 8 inches, and the width is 14 inches. The

Paha777 [63]

Answer: 2

Explanation:

The scale factor is the ratio between the scale drawing measures and the actual measures.

                                   scale drawing length            8 inches
scale factor = ratio = -------------------------------- =   --------------- = 2
                                        actual length                    4 inches

Also,
                                   scale drawing width             14 inches
scale factor = ratio = ----------------------------- =       --------------- = 2
                                     actual width                      7 inces

As seen the scale factor is 2.
