In the following exercises, use the mapping of the relation to (a) list the ordered pairs of the relation, (b) find the domain of the relation, and (c) find the range of the relation. 290. For a man of height 5'11'' the mapping below shows the corresponding Body Mass Index (BMI). The body mass index is a measurement of body fat based on height and weight. A BMI of 18.5 − 24.9 is considered healthy.

the force (in pound) you must exert on a wrench handle to loosen a bolt on a bike varies inversely as the length L (in inches) of the handle. A force of 30 pounds is needed when the handle is 8 inches long.
a. find an equaion that describe the relation between handles lenght and force.
b. if you use a 5 inch long wrench to loosen the bolt, how much force do you need to apply to the handle?
A car purchased for $10,000 depreciates in value by 10% per year. The car's value
over time is modelled by the relation V = 10000(0.9)t, where V is its value in
dollars, and t is the number of years since purchase. What is the value of the car
after 6 years?
The amount of metal that can be extracted from the ore is proportional to the amount
of the ore used. Complete the equation so that it satisfies the relation given in the
illustration below. Write your answer in the simplest form in the boxes given below.
[x: Weight of ore (in Ib), y: Weight of metal (in oz)]
y =
500 lb - ore
2 oz - Metal
