Answer: √9 = 3
Verification:
= 3 * 3
=> 9
64in/16in = x/18.5
64•18.5= 1184
1184/16x= 16x/16x
1184/16x
x= 74 in

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.

4 hours is 8 half hours
8*2 is 16 so the answer is d
Hope this helps :)
