Which ordered pair does NOT lie on the graph of the exponential function

It’s a hope that helps have a good one

The ordered pair does not lie on the graph of the exponential function

is (12, 0).

Option A is the answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To check whether an ordered pair lies on the graph of the exponential function f(x) = [tex]3(1/4)^x,[/tex]

We need to substitute the values of x and y into the function and see if the equation holds true.

A. (12, 0)

Substituting x = 12 and y = 0 into the function, we get:

[tex]f(12) = 3(1/4)^{12} = 0.000002861[/tex]

This does not equal y = 0, so (12, 0) does not lie on the graph of the function.

B. (-2, 48)

Substituting x = -2 and y = 48 into the function, we get:

[tex]f(-2) = 3(1/4)^{-2} = 48[/tex]

This does not equal y = 48, so (-2, 48) does lie on the graph of the function.

C. (2, 3/16)

Substituting x = 2 and y = 3/16 into the function, we get:

[tex]f(2) = 3(1/4)^2 = 3/16[/tex]

This equals y = 3/16, so (2, 3/16) does lie on the graph of the function.

D. (0, 3)

Substituting x = 0 and y = 3 into the function, we get:

[tex]f(0) = 3(1/4)^0 = 3[/tex]

This equals y = 3, so (0, 3) does lie on the graph of the function.

Therefore,

The ordered pair does not lie on the graph of the exponential function

is (12, 0).

Answers

Answer:

2/11 or

0.181818

Step-by-step explanation:

Because 8/11 in precent form is 72%

So, 72÷4= 18.

If you put 18 in decimal form, it will be:

.18

For the fraction answer, .18 will be 0.22

And 0.22 in fraction form will be 2/11.

So those are your answers.

I hope this helped      :)

The division of the equation A = ( 8/11 ) / 4 is A = 0.1818..

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

Substituting the values in the equation , we get

Let the first fraction be represented as p = ( 8/11 )

Let the second fraction be q = 4/1

Now , the equation is A = 8/11 divided by 4

On simplifying , we get

A = ( 8/11 ) / 4

A = ( 8/44 )

A = 0.181818181..

Therefore , the value of A is a recurring decimal number

Hence , the equation is A = 0.181818..

What is the area of a regular pentagon with an 8-cm
apothem and 11.6-cm sides?

Answers

Answer:

232.5 cm²

Step-by-step explanation:

232.5

The required area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².

What is surface area?

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
To find the area of a regular pentagon, we can use the formula:

Area = (1/2) x Apothem x Perimeter

where Apothem is the distance from the center of the pentagon to the midpoint of any side, and Perimeter is the sum of the lengths of all the sides.

In this case, the apothem is given as 8 cm, and the length of each side is given as 11.6 cm.

To find the perimeter, we can simply multiply the length of one side by 5:

Perimeter = 5 x 11.6 cm = 58 cm

Now, we can plug in these values into the formula:

Area = (1/2) x 8 cm x 58 cm

Area = 232 cm²

Therefore, the area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².

The equipment was estimated to have a 10-year service life and no residual value. The straight-line depreciation method was used to measure depreciation for 2019 and 2020. Late in 2021, it became apparent that sales of the new frozen food line were significantly below expectations. The company decided to continue production for two more years (2022 and 2023) and then discontinue the line. At that time, the equipment will be sold for minimal scrap values. The controller, Heather Meyer, was asked by Harvey Dent, the company's chief executive officer (CEO), to determine the appropriate treatment of the change in service life of the equipment. Heather determined that there has been an impairment of value requiring an immediate write-down of the equipment of $12,900,000. The remaining book value would then be depreciated over the equipment's revised service life. The CEO does not like Heather's conclusion because of the effect it would have on 2016 income. "Looks like a simple revision in service life from 10 years to 5 years to me," Dent concluded. "Let's go with it that way, Heather."
