Find the the domain codomain and range of the graph

Mathematics

Answer:

Domain: All Real numbers

CoDomain : All Real numbers

Range: $\left\{y|y\geq 0 \right\}$ ; that is: Real numbers larger than or equal to zero

Step-by-step explanation:

Notice that the graphed function can use any Real number x (from - infinity to + infinity) and produce an output. Therefore, the Domain of the function plotted in graph 3 is : All Real numbers.

The set of possible outputs (CoDomain) is also the set of all Real numbers (notice that the y-axis extends form - infinity to + infinity

But the Range (the actual set of the collection of outputs of the function) is just a subset of the CoDomain consisting of the Real numbers larger than or equal to zero (notice that the drawing of the function touches the x axis and lies completely on the upper half of the plane.

On one day, 4 chefs and 5 helpers earned $650.

Arlecino [84]

4c + 5h = 650 and

5c + 6h = 800 where c are chefs, h are helpers

Start by finding an expression for c

4c + 5h = 650
4c = 650 -5h
c = (650- 5h)/4

Then substitute that into the second equation and solve for a number value for h
5 (650-5h)/4 + 6h = 800
(3250-25h)/4 + 6h = 800
Multiply both sides by 4
3250-25h + 24h = 3200
-h = -50
h = 50

Take that 50 and substitute it into the expression we have for c to get a number value for c

C= 650-5(50)/4
C = 650-250/4
C = 400/4
C= 100

Check your first equations, substituting $50 for the helpers and $100 for the chefs.

4 (100) + 5(50) =
400 + 250 = 650

5(100) + 6(50) =
500 + 300 = 800

3. Siti and Mary shared $35 in the ratio 4:3. How much money did Siti receive?

Mashcka [7]

Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

$4:3 \rightarrow 4:(3+4)=4:7$

Now we can solve for how much money Siti receives using a proportion.

$\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}$

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.

The number of cubic inches in the volume of a 6-inch high cylindrical can equals the number of square inches in the area of the

Svetradugi [14.3K]

Answer:

In inches, the radius of the can is 2.

Step-by-step explanation:

Given:

The number of cubic inches in the volume of a 6-inch high cylindrical can equals the number of square inches in the area of the label that covers the lateral surface of the can.

Now, to find the radius of the can in inches.

Let the radius of can be $r.$

Height of can = $6\ inches.$

As given, the number of cubic inches of the volume of the cylindrical can equals the number of square inches in the area of the label that covers the lateral surface of the can.

So,

Volume of can = lateral surface area of can.

Now, we put formula of volume and lateral surface area of cylinder:

$\pi r^2h=2\pi rh$
