Answer:
The answer is C, The use of Pi can be used to find the ratio of the diameter and circumference of a circle
Step-by-step explanation:
This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.

sorry i cant help
Step-by-step explanation:
Answer:
center = (3, 0)
radius = 2
Step-by-step explanation:
Standard equation of a circle: 
(where (h, k) is the center of the circle and r is the radius)
Given equation:

Rewrite in standard form:

Therefore
- center = (3, 0)
- radius = 2
Answer:
100
Step-by-step explanation:
they are vertical angles therefore, they have the same measure.
