Answer:

A relation is a subset of cartesian product of two non empty sets whereas A function is a type of relation in which every element of first set has one and only image in the second set.

In a relation an element of the first set can have many images in the second set whereas in a function the first element can have only one image in the second set.

The given relation is not a function as the element 1 is related to 3 different elements in the second set.

Domain={1}

Range={7,14,21}

A cylindrical paint can has a capacity of one gallon. for another size can, the height is doubled. what is the capacity of the l
skelet666 [1.2K]
We know that

[volume of a <span>cylindrical paint can 1]=[area of the base]*h
so
</span>[area of the base]*h=1 gallon

if <span>the height is doubled
</span>[volume of a cylindrical paint can 2]=[area of the base]*(2*h)
[volume of a cylindrical paint can 2]=2*{[area of the base]*h)}
[volume of a cylindrical paint can 2]=2*[volume of a cylindrical paint can 1]
[volume of a cylindrical paint can 2]=2*[1 gallon]-----> 2 gallons

the answer is
<span>the capacity of the lager one is 2 gallons</span>

mrs.saledo wants to buy 1 1/2 quarts of whipping cream if whipping cream is sold in only 1 pint containers , how many containers
hram777 [196]

Answer:

She needs to buy 3 such containers.

Step-by-step explanation:

Mrs. Saledo wants to buy 1\frac{1}{2} quarts of whipping cream.

Now, 1\frac{1}{2} quarts = \frac{3}{2} quarts = \frac{3}{2} \times 2 = 3 pints.

Since we know that 1 US liquid quart = 1 US liquid pints.

If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )
