the third set represent a function

For the points to represent a function then for each value of x there can only be one corresponding value of y

sets 1, 2 and 4 do not obey this and have more than one value of y for a given x

set 1

1 → 1, 2, 3, 4, 5

set 2

3 → 3, - 3 and 5 → 5, - 5

set 4

- 1 → - 1, 1 and - 2 → 4, - 4

mezya [45]

Answer:

a. \pi r^2h

b. \frac{4\pi r^2h}{5}

Step-by-step explanation:

Volume of the container denotes its quantity. It is a three-dimensional space.

Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.

a.

The total capacity of the container in terms of π is \pi r^2h<u />

b.

As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is \frac{4}{5}\times volume of the container i.e., \frac{4\pi r^2h}{5}

The equation's X-y= 2, -2y=-2, X+ y = 2, and x+2y=-2 are shown on the graph below.
ziro4ka [17]

Answer:

A.) x-y=2 and x+2y=-2

Step-by-step explanation:

For option A, we have:

x-y=2

x+2y=-2

Subtract the first equation from the second, to get:

2y--y=-2-2

This implies that:

2y+y=-2-2

Simplify to get:

3y=-4

Divide both sides by 3 to get:

y =  -  \frac{4}{3}  =  - 1.3

We substitute y=-1.3 into the first equation to get:

x--1.3=2

x+1.3=2

x=2-1.3

x=0.7

The solution is (0.7,-1.3), which is approximately (0.7, -1.4)

By inspection, all the other factors have solutions not close to (0.7, -1.4)

A recipe uses 5 cups of milk to make 10 servings. If the same amount of milk is used for each serving, how many servings can be
Margaret [11]

Answer: 24 servings

Step-by-step explanation:

First and foremost, we should note that:

4 cups = 1 quart

Therefore, 3 quarts = 3 × 4 cups = 12 cups

Since she uses 5 cups of milk to make 10 servings, it means that 1 cup of milk is used to make 2 servings. Therefore, 12 cups would be used to make:

= 12 × 2

= 24 servings.
