Answer:
Rabbit is faster than bear.
Step-by-step explanation:
Speed of rabbit or bear is determined by their rate of change of their distances with time.
The distance covered by rabbit in hours is given as:
The above equation is of the form , where,
is the rate of change of
with
.
Therefore, the rate of change of rabbit's distance with time is 30 mi/h.
Now, from the graph, the slope is given as the rise over run.
Rise is 50 miles and run is 2 miles.
So, rate of change of bear's distance with time is,
Now, 30 is greater than 25. So, rabbit is faster than bear.
Based on the current population and the rate of decrease, the population in five years will be 88,529 people.
<h3>What is the rate of change of the amount?</h3>Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable.
This can be found by the formula:
= Current population x ( 1 - rate%) ^ number of years
Given that,
Current population = 100,000, rate = 3%, number of years = 4
= 100,000 x
= 100,000 x 0.88529281
= 88,529 people
Hence, The population in five years will be 88,529 people.
