Answer:
(a) 0.107 million per year
(b) 0.114 million per year
Step-by-step explanation:

(a) The average rate of change between 2000 and 2014 is determined by dividing the difference in the populations in the two years by the number of years. In the year 2000,
and in 2014,
. Mathematically,


(b) The instantaneous rate of change is determined by finding the differential derivative at that year.
The result of differentiating functions of the firm
(where
is a constant) is
. Let's use in this in finding the derivative of
.

In the year 2014,
.

Answer:
-30
Step-by-step explanation:
let Sarah's number be X
x-15=15x
15x*-5=105
-75x=105
-x=105-75
X=-30

Hey there :)
Without using a calculator it is not hard to identify where it lies.
√88
Which are the perfect squares before and after √88 ?
√81 which is 9 and √100 which is 10
Therefore, √88 is between 9 and 10
In case you use a calculator, we can see that:
√88 = 9.38
9 < 9.38 < 10
