Which set of ordered pairs do NOT represent a function?

Mathematics
1 answer:
Rainbow [258]3 years ago
7 0

Answer:

Every input can have only one output. But an output can have multiple inputs. Basically an x coordinate can have the same y coordinate as another ordered pair but not the same x coordinate. This is why d) does not represent a function.

Step-by-step explanation:

(4,-2)

(4,2)

4 is mentioned twice and every input( x value) can have only one output ( y-value)

Complete the remainder of the
allsm [11]

The corresponding values needed will be -23, -8, 7 and 22

<h3>Functions and Tables</h3>

Given the function y = 5x - 8

<h3>Get the domains and range</h3>

We are to get the range of the function for the given domains

If the value of x is -3

y = 5(-3) - 8

y = -15 - 8

y = -23

If the value of x is 0

y = 5(0) - 8

y = 0 - 8

y = -8

If the value of x is 3

y = 5(3) - 8

y = 15 - 8

y = 7

If the value of x is 6

y = 5(6) - 8

y = 30 - 8

y = 22

Hence the corresponding values needed will be -23, -8, 7 and 22

3. Give the slope and y-intercept of the<br> relationship shown in the table.
kolezko [41]

Answer:

B

Step-by-step explanation:

Since the slope is going down the slope is negative and since 50 is positive when 0 its positive.

Also to find slope you do y/x

25/100=1/4 and since its a decreasing pattern the slope is -1/4

What is the approximate surface area of the sphere if circumference is 37.68?
damaskus [11]

The surface area of a sphere is  A = 4 π R² .

Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.

                           Circumference = π (diameter)

Divide each side by π :  Diameter = circumference / π

Radius = 1/2 diameter:  Radius = circumference / (2 π)

                                       Area = 4 π R²  =

                                                 4 π (circumference/2π)² =

                                                 4 π (circumference)² / 4 π²

Divide top and bottom by  4π :  Area = (Circumference)² / π

         Circumference = 37.68 units

         Area =  (37.68)² square units /π =
    
                       <em>451.93 square units</em>
