A scuba diver dove from the surface of the ocean to an elevation of -69 9/10 feet at a rate of -21.5 feet per minute. After spending 13 minuets at that elevation the diver ascended to an elevation of -8 9/10 feet. The total time for the diver so far was 20 1/8 minutes. What was the rate of change in the divers elevation during the ascent? Round your answer to the nearest hundredth.

the real question is why is this guys last name heavyfoot

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
