Using the vertex of a quadratic function, it is found that Phoenix received the highest amount of precipitation on the month of May.
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:
The vertex is given by:
In which:
Considering the coefficient a, we have that:
- If a < 0, the vertex is a maximum point.
- If a > 0, the vertex is a minimum point.
In this problem, the precipitation each month x in Phoenix is given by:
Hence the coefficients are a = -0.04088, b = 0.4485, c = 1.862, and the month for which the precipitation will be highest is given by:
Hence during the month of May.

Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts
Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)
Find one part of the share for each axes, we do
Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4
The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)
Correct answer: A
Answer: 
This the expression -3*sqrt(3) or "-3 times the square root of 3"
=================================================
Work Shown:
Factor each term inside the square root so that a perfect square is one of the pieces. Then break up the roots and simplify as shown below.
