Answer:
<em>V = π(2.5)²(7)</em>
Step-by-step explanation:
<u><em>Given:</em></u>
<em>A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height of 7 inches. </em>
<u><em>To Find:</em></u>
<em>which equation could be used to determine the volume, in cubic inches, of the vase?</em>
<u><em>Solve:</em></u>
<em>Formula for cylinder volume: Volume = πr²h</em>
<em>Where,</em>
<em>h represents the height of the cylinder</em>
<em>r represents the radius of the cylinder.</em>
<em>π is a constant whose value is 3.14</em>
<em />
<em>Knowing that:</em>
<em>Diameter = 5 in</em>
<em>Height = 7 in</em>
<em>Radius = 2.5 {Radius is half of diameter so 5/2 = 2.5}</em>
<em>Thus, a equation could be use is:</em>
<em>V = π(2.5)²(7)</em>

The answer to this question is that there are many integers with deifferent signs when added the answer is 8.
For example,
+13 and -5 are two integers with different signs when added the answer will b 8.
The sum of integers +12 and -4 is also 8. +11 and -3, +10 and -2, +14 and -6 also gives 8 answer when added.
There are many others.
Using the vertex of a quadratic equation, it is found that the company should charge each customer $15 per day to maximize revenue.
<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 number of bikes rented per day is given by:
n(p) = 300 - 10p.
Hence, the revenue function is given by:
R(n) = p x n(p)
R(n) = 300p - 10p².
Which is a quadratic function with coefficients a = -10, b = 300. Hence, the price in dollars that will maximize the revenue is given by:
