Answer/Step-by-step explanation:
1. PN = 29
MN = 13
PM = ?
(Segment addition postulate)
(subtract MN from each side)
(substitute)


2. PN = 34, MN = 19, PM = ?
(sediment addition postulate)
(subtract MN from each side)
(substitute)


3. PM = 19, MN = 23, PN = ?
(Segment addition postulate)
(substitute)

4. MN = 82, PN = 105, PM = ?
(segment addition postulate)
(subtract MN from each side)
(substitute)


5. PM = 100, MN = 100, PN = ?
(Segment addition postulate)

A function that gives the amount that the plant earns per man-hour t years after it opens is 
<h3><u>Solution:</u></h3>
Given that
A manufacturing plant earned $80 per man-hour of labor when it opened.
Each year, the plant earns an additional 5% per man-hour.
Need to write a function that gives the amount A(t) that the plant earns per man-hour t years after it opens.
Amount earned by plant when it is opened = $80 per man-hour
As it is given that each year, the plants earns an additional of 5% per man hour
So Amount earned by plant after one year = $80 + 5% of $80 = 80 ( 1 + 0.05) = (80 x 1.05)
Amount earned by plant after two years is given as:

Similarly Amount earned by plant after three years 

Hence a function that gives the amount that the plant earns per man-hour t years after it opens is
