A function rule could simply be: c = 420h , where c is the total number of calories burned and h is the number of hours riding at 15 mi/hr.
All you need to do is plug in the number of hours that he rode at this rate and multiply it by 420.
Answer:
Find out the what function equation represents the population of the city after t years .
To prove
The population of a city is 451,400. The population is expected to decrease at a rate of 3.2% each year.
This can be represented by exponential decreasing function.

Where a is the initial value.
r is the rate in decimal form
t is the time.
Here
a = 451,400
3.2 % is written in the decimal form.

= 0.032
Put in the formula


Therefore the decrease in the population of the city after t years is represented by
