Answer:
A linear function is represented
Step-by-step explanation:
The table is:
x f(x)
0 10.00
1 10.02
2 10.04
3 10.06
4 10.08
5 10.10
If we compute the difference between two consecutive function values and we divide it by the difference between their associated x values we get:
(10.02 - 10.00)/(1-0) = 0.02
(10.04 - 10.02)/(2-1) = 0.02
(10.06 - 10.04)/(3-2) = 0.02
(10.08 - 10.06)/(4-3) = 0.02
(10.10 - 10.08)/(5-4) = 0.02
This constant result indicates that a linear function is represented.
Answer:
x - 18°F = 2°F
x = 20°F
Step-by-step explanation:
First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F
Your equation should look like this: x - 18°F = 2°F
Move the constant to the right hand side and change it's sign:
x = 2°F + 18°F
Add the numbers to get x = 20°F

This is because there is an imaginary 1 in front of the first sqrt.
Answer:
P(0) = 7,917
Step-by-step explanation:
The population of the community is given by the following formula:
In which P(0) is the initial population and r is the growth rate.
The initial population P0 has doubled in 5 years.
This means that
Which lets us find r.
Applying the 5th root to both sides
So
Suppose it is known that the population is 12,000 after 3 years.
With this, we find P(0)
