Answer:

A public communications director would make $1,196,800 over a period of 20 years.

Step-by-step explanation:

The median salary of an engineer is $73,400 per year.

Piper has researched that a public communications director makes $13,560 less than this. (so we need to take this amount from the salary of an engineer)

Therefore, we would have that a public communications director would make

73,400 - 13,560 = $59, 840 per year

Now, the problem asks us how much a public communications director will make over a period of 20 years, thus, we have to multiply the amount she will get per year by 20.

Thus, over 20 years she would make: 59,840 x 20 = $1,196,800

Arturiano [62]

Answer:

- 1

Step-by-step explanation:

Let the slope of one line be 's' , then according to the given condition that the slope of second line is negative reciprocal of the first , We obtain the slope of the second line as $\frac{-1}{s}$ .

So, the product of both the slopes is given by $s\cdot \frac{-1}{s}=-1$

This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
