difference between a function and a relation

Answers

A function is a special kind of relation. Relations pair up x and y coordinates, either by listing them (explicitly) or by writing an equation (implicitly). Functions have the additional property that no two values of y have the same value of x. Put another way, if you view x as the input and y as the output, functions have the property that each input yields only one output.

A relation is any set of ordered pairs.

For example, {(5,9), (1,2), (8,11), (10,20), (4,7)}

A function is a special type of relation where each x-coordinate has exactly 1 y-coordinate.

A 20,000 gallon swimming pool contains 5000 gallons of water when a hose is placed into the pool and begins adding water at a rate of 1250 gallons per hour. Use the Segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed into the pool until it is full.

Answers

20000-5000=15000

15000/1250=12

it will take 12 hours

Solution: The figure 1 shows the graph of the volume of water in the pool over the time from when the hose is placed into the pool until it is full.

Explanation:

It is given that the capacity of the pool is 20,000 gallon and initial water in the pool is 5000 gallons. The remaining capacity of the pool is 15,000 gallons.

The water in the pool increased at the rate of 1250 gallons per hour.

[tex]\frac{15000}{1250}=12[/tex]

So tank will be full after 12 hours.

The initial water in the pool is 5000 gallons and water in the pool increased at the rate of 1250 gallons per hour. So, the volume of water in the pool is described by the equation [tex]V=5000+1250t[/tex].

First we find the value of volume function in different value of t, then plot these points in a coordinate plane and join them with a straight line.

Hence, the coordinate table and graph of the volume function is given below.

The answer is The total area of the top and bottom squares. s = √7 cm is irrational value and we need rational value. Let's check all choices: A. The volume. V = (s)^3. If s = √7, V = (√7)^3 = 7√7 - irrational value. B. The perimeter of the front square. P = 4 * s = 4 * √7 = 4√7 - irrational value. C. The diagonal of the back square. d = s√2 = √7 * √2 = √(7*2) = √14 - irrational value. D. The total area of the top and bottom squares. A = 2 * s^2 = 2 * (√7)^2 = 2 * 7 = 14 - rational value.

Danika and Karen bought a pizza that was cut into 8 slices. If Danika ate 3/4 of the pizza, how many slices were left for Karen?

Answers

2 slices left for karen

Since 4/4 is 8, to solve for 1/4, you have to divide 8 by 4, which is 2. 1/4 = 2, so 2/4 = 4, and 3/4 = 6. Danika ate 6 slices of pizza because she ate 3/4 of the pizza. Since there is only 1/4 left, Karen only has 2 slices of pizza left. Another way you could do it is you could subtract 6 from 8 to get the remaining amount, and you would still get 2 slices left for Karen.

Answers

d because 5 divided by 2 is 2.5

The solution is Option D.

The unit rate of the cost per box is given by the equation A = $ 2.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The selling price of 2 boxes of cookies = $ 5

So , the cost of 1 box of cookies A = selling price of 2 boxes of cookies / 2

Substituting the values in the equation , we get

Cost of 1 box of cookies A = 5/2

Cost of 1 box of cookies A = $ 2.50

Therefore , the value of A is $ 2.50

Hence , the unit rate of box of cookies is $ 2.50

a manager purchased a total of 21 coffee mugs and key chains. each coffee mug cost $8.50, and each key chain cost $2.75 . if manager spent total of $132.50, how many coffee mugs did the manager purchase

Answers

Final answer:

The manager purchased 13 coffee mugs.

Explanation:

To find the number of coffee mugs purchased, we can set up a system of equations. Let's say the number of coffee mugs is represented by x and the number of key chains is represented by y. We have two pieces of information:

1. The total number of items purchased is 21: x + y = 21

2. The total cost of the purchase is $132.50: 8.50x + 2.75y = 132.50

Now we can solve this system of equations to find the value of x, which represents the number of coffee mugs:

Multiplying the first equation by 8.50, we get: 8.50x + 8.50y = 178.50

Subtracting the second equation from this new equation, we get: 8.50x + 8.50y - 8.50x - 2.75y = 178.50 - 132.50

Simplifying, we have: 5.75y = 46

Dividing both sides of the equation by 5.75, we find: y = 8

Substituting this value into the first equation, we can solve for x: x + 8 = 21

x = 13

Therefore, the manager purchased 13 coffee mugs.

Marc is running 5 kilometers at track practice. He decides to break the run into 3 equal lengths. How long will each length be?

Because "4 or less let it rest, 5 or more raise the score"

Each length of the track practice will be 1.67 kilometers.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Marc is running 5 kilometers at track practice.

And, He decide to break the run into 3 equal lengths.

Now,

Since, Marc is running 5 kilometers at track practice.

And, He decide to break the run into 3 equal lengths

So, The length of each track practice = 5 / 3

= 1.67 kilometer

Thus, Each length of the track practice will be 1.67 kilometers.

Consider the two functions shown here. Which function has the greater rate of change? Explain your answer.
A) Function 1, because the rate of change is 2.
B) Function 2, because the rate of change is ½.
C) Function 2, because the rate of change is 7.
D) Function 1, because the rate of change is ½ .

Answers

rate of change = slope

function 1 :
(0,0)(1,2)
slope = (2 - 0) /(1 - 0) = 2/1 = 2

function 2 : y = 1/2x + 7...in y = mx + b form, the slope is in the m position.
so ur slope here is 1/2.
