Answer:
The unit rate is -0.5 store per year
Step-by-step explanation:
Let
x -----> the number of years since 1996
y ----> the number of video rental stores
we know that
The year 1996 represent x=0
so
2016 represent ----> x=2016-1996=10 years
we have the points
(0,9) and (10,4)
The unit rate is equal to the slope of the linear equation
<em>Find the slope m</em>
----> is negative because is a decreasing function
therefore
The unit rate is -0.5 store per year
The puppy gained 7 pounds. So, we must wonder: which percentage of 5 is 7? We can write the proportion
and solving for x we have
Answer:
Step-by-step explanation:
The initial value of the population is 650
Each year the population increases 160
The population oscillates 19 above and below.
Due to this information you can assume that the function is:
where for t=0 p(t)=650
where t=12 160/12 (12) = 160
you can assume that the sinusoidal function has a period of one month. Thus, the population oscillates several times in one year with an amplitu of the oscillation of 19. The, w is:
