It is convenient to do part b first, then use that result to do part a.
b. For some pair of points (x1, y1) and (x2, y2), you want to find a point (a, b) such that (a, b) - (x1, y1) = (x2, y2) - (a, b). That is, the differences of coordinates from one end to the center are the same as the differences from the center to the other end.
Adding (a, b) to the above equation gives
2(a, b) - (x1, y1) = (x2, y2)
Adding (x1, y1) then gives
2(a, b) = (x1, y1) + (x2, y2)
Finally, dividing by 2 gives a formula for (a, b):
(a, b) = ((x1, y1) + (x2, y2))/2
The midpoint is the average of the end points.
a. Using the result from part b, the midpoint is
midpoint = ((2, 3) + (6, 7))/2 = (8, 10)/2
midpoint = (4, 5)
40hours x $11 = $440
3hours x $16.50 = $49.50
$440 + $49.50 = $489.50
Unit of measurement in a formula suggests a definite magnitude of a certain quantity. For instance, there are basic unit of measurement for the 7 basic quantities: These are
1. seconds (s) for time
2. meter (m) for length
3. candela (cd) for luminous intensity
4. Ampere (A) for electric current
5. Kelvin (K) for Temperature
6. Kilogram (kg) for mass
7. mole (mol) for amount of substance
These units of measure should be homogenous in a formula for easy interpretation. Other derived quantities (e.g volume) also have their corresponding units as well as those quantities which are not based on the metric systems (e.g Celsius, pounds, etc)
