Answer:
The maximum possible number of mosquitoes is 25 millions
Step-by-step explanation:
Let
m(x) -----> the number of mosquitoes in Minneapolis, Minnesota (in millions of mosquitoes)
x ----> the rainfall in centimeters
we have
This is a quadratic equation (vertical parabola) open downward
The vertex is the maximum
we know that
The maximum possible number of mosquitoes is equal to the y-coordinate of the vertex
Find out the coordinate of the vertex
The general equation of a vertical parabola in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex
so
In this problem
a=-1 (open downward)
(h,k)=(5,25)
The y-coordinate is 25
therefore
The maximum possible number of mosquitoes is 25 millions
Question: What is the composite number?
Answer: A composite number is defined as a number that has divisors other than 1 and the number itself.
Step-by-step explanation: Start counting: 1, 2, 3, 4, 5, 6, .... so on. 1 is not a composite number because its sole divisor is 1. 2 is not a composite number because it has only two divisors, i.e., 1 and the number 2 itself.
The expression is telling you to proceed as follows:
- Pick some number
- Pick some number
- Compute the square of
- Multiply it by 4
- Subtract
from this result.
So, first of all, there's no point in fixing , because x doesn't appear in the expression. As for the evaluation, let's follow the aforementioned steps with fixed values:
- Pick
- Pick
- Compute
- Multiply it by 4:
- Subtract
from this result:
