If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter. What is the volume of the tank? Assume that 3.14 is the value for pi.

Answers

h = 3 m, d = 6 m , so: r = 3 m;
The volume of the tank is:
V = r² π h = 3² · 3.14 · 3 = 9 · 3.14 · 3 = 27 · 3.14 = 84.78 m³

Answer:

The volume of the tank is $84.78\ m^(3)$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^(2)h$

In this problem we have

$r=6/2=3\ m$ -----> the radius is half the diameter

$h=3\ m$

substitute

$V=(3.14)(3^(2))(3)=84.78\ m^(3)$

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros? The equation has one zero because the discriminant is 1. The equation has one zero because the discriminant is a perfect square. The equation has two zeros because the discriminant is greater than 0. The equation has no zeros because the discriminant is not a perfect square.

Answers

The correct option is: The equation has two zeros because the discriminant is greater than 0.

Explanation:

First, remember the following conditions:
1. If the discriminant is less than zero, there will be no zeros.
2. If the discriminant is equal to zero, there will be one zero.
3. If the discriminant is greater than zero, there will be two zeros.

For the general equation of the form $ax^2 + bx + c = 0$ , the discriminant is $b^2 - 4ac$ .

Let's find the discriminant and then compare it with the conditions mentioned above.

Given Equation:
$3x^2 -7x + 4 =0$

a = 3, b = -7, c = 4

Now find the discriminant:

$b^2 - 4ac$
$(-7)^2 - 4(3)(4)$
Discriminant = 1

As the discriminant is greater than 0 (which in this case is 1), the equation has two zeros (as mentioned in the above conditions).

Can you have 2 vertical asymptotes?

Answers

YES. you can have 2 vertical asymptotes.

So I'll set the denominator equal to zero and solve. Since I can't have a zero in the denominator, then I can't have x = –4 or x = 2 in the domain. This tells me that the vertical asymptotes (which tell me where the graph can not go) will be at the values x = –4 or x = 2. hope this helped.:)
