Answer: B
Step-by-step explanation:
If an absolute value of a negative number plus a absolute value of the positive number is positive. Absolute value of anything is positive.
For this case we have that by definition the growth of a population is a function of the form:

Where,
- <em>a: initial population
</em>
- <em>b: growth rate
</em>
- <em>x: number of years
</em>
We observe then that the function is of the exponential type.
Answer:
C) Exponential
Answer:
we know that
the equation of the circle is of the form
(x-h)^2+(y-k)^2=r^2
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
(x+5)^2+(y-k)^2=r^2
so
the center is the point (-5,3)
the radius is 4 units
therefore
the answer is
The radius of the circle is equal to 4 units
