Answer:

8\ glasses\ of\ juice

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=4\ in\\ h=12\ in

substitute the values

V=\pi (4)^{2}(12)=192\pi\ in^{3}

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=2\ in\\ h=8\ in

substitute the values

V=\pi (2)^{2}(8)=32\pi\ in^{3}

Find the volume of 3/4 of the glass

32\pi (\frac{3}{4})=24\pi\ in^{3}

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice

He graph of the function f(x) = –(x + 6)(x + 2) is shown below.
Molodets [167]

The domain of the function is all real numbers, the range of a function is y ≤ 4

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = –(x + 6)(x + 2)

If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.

Here the no other details are given.

But we can say:

  • The domain of the function is all real numbers.
  • The range of a function is y ≤ 4
  • The x-axis intercept will be at (-6, 0) and (-2, 0).

Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4

Answer:

Answer and Explanation:

In solving y = 2x - 4, we find that the slope of the line is 2, the y-intercept of the line is y = -4, and the x-intercept of the line is x = 2.

I hope this helps.
