State which of the following sets of ordered pairs represent a function.

Set A: (5,2), (4, 3), (3, 4), (2,5)
Set B: (-1,-6), (0, 2), (1, 2), (3, 6)
Set C: (2, 1), (4, 2), (2, 3), (8,4)


Please select the best answer from the choices provided

A: Set C
B: Set B
C: Set A
D: Set A and Set B​

Answers

Answer:

Option (D) is correct.

Step-by-step explanation:

A function can be termed as a process from a set of x values to a set of possible y-values where each x-value relates to exactly one y-value.

In other words, a relation can only be a function there is no repetition of x-values. It means a relation can not have duplicated inputs.

Given the sets

Set A: (5,2), (4, 3), (3, 4), (2,5)

Set B: (-1,-6), (0, 2), (1, 2), (3, 6)

Set C: (2, 1), (4, 2), (2, 3), (8,4)

It is clear that sets A and B represent the function because, in these sets, each x-value relates to exactly one y-value. In other words, there are no duplicated inputs.

But, set C has duplicated inputs i.e. x = 2 is repeated twice, and a function can not have a repeated input.

Therefore, we conclude that set A and set B represent a function.

Thus, option (D) is correct.

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8200 ​ft, the liquid boils at 199.42°F. At an altitude of 4700 ​ft, the liquid boils at 206.07°F. Write an equation giving the boiling point b of the​ liquid, in degrees​ Fahrenheit, in terms of altitude​ a, in feet. What is the boiling point of the liquid at 2500 ​ft?
Write an equation.
b=

Answers

Answer:

b=-0.0019a + 215

at 2500 ft, b=210.25 degrees F

Step-by-step explanation:

First find the slope. a=altitude, b = temperature

slope is b2-b1 / a2-a1

points are (8200, 199.42) and (4700, 206.07)

(206.07 - 199.42) / (4700-8200)

= 6.65/ -3500

= - 0.0019

we have b = -0.0019a + intercept

plug in a point to find intercept

199.42 = -0.0019*8200 + intercept

intercept = 199.42 + 15.58 = 215

b=-0.0019a + 215

at a=2500 ft, substitute into equation

b= -0.0019*2500 + 215

= -4.75 + 215

= 210.25 degrees F

Answers

Answer:

44 degrees

Step-by-step explanation:

To start things off, we need to understand that all three triangles enclosed within the rectangle are identical, or better still, in this case, we can say that they are exactly the same.

This implies that the dimensions for the first triangle are the same as that f the second and the third.

we have the dimensions of the first triangle as 92 degrees, 44 degrees, and < DGA.

Recall that the sum of the angles in a triangle = 180 degrees.

< DGA = 180 - (92 + 44) = 44 degrees.

since the triangles are identical, < EHB = < DGA. = 44 degrees

And we are expected to find f(6), that is substitute the value of x with 6

Step two:

[tex]f(6)= 2/3(6)+3\\\\f(6)=2/18+3\\\\f(6)=1/9+3\\\\f(6)=1+27/9\\\\f(6)= 28/9[/tex]

The population of a city decreases by 3.7% per year. If this year's population is 211,000, what will next year's population be, to the nearest individual?​

Answers

Answer:

20,3193

Step-by-step explanation:

Population decrease per year in city = 3.7%

Current population = 211,000

Next year's population = 211,000*3.7/100

                                      = 7807

                                      = 211,000-7807

                                      =203193

Next year's population= 203193

Therefore, next year's population will be equal to 20,3193.

The next year's population is 203193.

Given that, the population of a city decreases by 3.7% per year.

What is population growth and population decrease formula?

If a constant rate of growth be R% per annum, then population after n years = [tex]P(1+\frac{R}{100})^n[/tex].

If the constant decrease in population be R% per annum, then the population after n years = [tex]P(1-\frac{R}{100})^n[/tex].

This year population is 211,000.

Now, [tex]211000(1-\frac{3.7}{100})^1[/tex]

= 211000×0.963

= 203193

Hence, the next year's population is 203193.

do 33 divided by 2 (2= half) you get 16.5, you cant have half a stamp so remove the .5 to get 16, add 8 to get 24

Answer:

50

Step-by-step explanation:

If he sells half of his stamps and buys 8 more after and ended up with 33 I would take away 8 (33-8=25) and get 25 (which is the other half that he didn't sell). After figuring out what the other half was you would double this number and get your starting number which is 50 ( 25*2= 50)

So this is the set-up
