Answer:
<h2>V = 235.5 in³</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
From the pictue we have r = 5in and H = 3in. Substitute:


Therefore

H(10)=8(10)+10
h(x)=90

Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:

In this case you have the following Quadractic function provided in the exercise:

Let's make it equal to 0:

You can identify that:

Knowing these values, you can substitute them into the formula and then evaluate:

Therefore, since:

You can determine that the it has two distinct real roots.
Simplify:
7x+3=7x-3
Now 7x goes away and you get 3=-3, which cannot be true, so there is no solution
Circumference is given by
