Problema Solution
According to one model, an animal's heart rate varies according to its weight. The formula N(w)= 885w raised to -1/2 gives an estimate for the average N of beats per minute for an animal that weighs w pounds. Use the formula to estimate the heart rate for a horse that weighs 800 pounds.
Answer provided by our tutors
Given N(w) = 885 w^(-1/2)
Plug in w = 800 and calculate
N(800) = 885 * 800^(-1/2)
= 885 * 0.0354
= 31.29
