help asap please.

Answers

Answer 1

Answer: D. X = 6 maps to y = 2

Step-by-step explanation:

i guessed and got it right lol

Answer 2

The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.

This mapping is not possible because we can not have the same inputs for different outputs.

y = 4 when x = 6 (given)

Option D is the answer.

What is a function?

A function is a relationship between inputs where each input is related to exactly one 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,

Function:

A function can have the same output for different inputs.

A function can not have different outputs for the same inputs

Now,

y = 4 when x = 6.

Other possible mappings are:

x = 4 maps to y = 6

This mapping is possible.

x = 3 maps to y = 2

This mapping is possible.

x = 0 maps to y = 0

This mapping is possible.

x = 6 maps to y = 2

This mapping is not possible because we can not have the same inputs for different outputs.

y = 4 when x = 6 (given)

x = 1 maps to y = 6

This mapping is possible since we can have different inputs for the same outputs.

Thus,

The option that does not represent another possible mapping in the relation is x = 6 maps to y = 2.

This mapping is not possible because we can not have the same inputs for different outputs.

y = 4 when x = 6 (given)

Option D is the answer.

Put the following numbers in order from least to greatest.
0.52
0.6
14/25
57%

Answers

Answer:

57% 0.52 14/25 0.6

Step-by-step explanation:

all you have to do is change all of the numbers into decimals

hope this helps :)

First, convert each to the same (#/#, 0.#, or #%). I'll use decimals (usually the easiest). 0.52 and 0.6 remain the same. 14/25 may seem hard at first, but you can change it to 56/100 (14*4/25*4=56/100), then you can use that to convert to 56%. Multiply by 0.01, or divide by 100, remove the %, and you will get 0.56. For 57%, you just need to do repeat the last step again, which will give you 0.57. From least to greatest, the list would be 0.52, 0.56, 0.57, and 0.6, or 0.52, 14/25, 57%, and 0.6.

Diana is going camping with her family. Their campsite is 7/8 miles away. They walk at a steady speed of 2 1/2 mi/h. How many minutes will it take them to get to the campsite

Answers

Answer:

21 minutes

Step-by-step explanation:

Using the formula to calculate the time expressed as;

Speed = Distance/Time

Given:

Distance = 7/8 miles

Speed = 2 1/2 mi/hr

Required

Time in minutes

Substitute the given values into the formula;

Recall that:

S = D/T

T = D/S

Time = 7/8 ÷ 2 1/2

Time = 7/8 ÷ 5/2

Time = 7/8 * 2/5

Time = 7/4 * 1/5

Time = 7/20 hour

Since 1 hour = 60 minutes

7/20 hour = (7/20 * 60)minutes

7/20 hour = 7 * 3

7/20 hour = 21 minutes

Therefore it will take them 21 minutes to get to the campsite

Laura borrowed $105,000 at a rate of 6% simple interest for 12 years. How much interest will Laura pay?
Group of answer choices

$75,600

$37,800

$180,600

$256,200

Answers

Answer:

Laura will pay an interest of $75,600.

Step-by-step explanation:

Our formula: A = P(1 + rt)

Principal = $105,000

Rate = 6%

Time = 12 years

A (amount)= 105,000(1 + (0.06 × 12)) = 180,600

$180,600 - $105,000 = $75,600.

Find the product (у- 2)(5у2 + 3y - 1)

Answers

Answer:

5y^3 - 7y^2 - 97y + 2 <<<< Answer

Step-by-step explanation:

(у- 2)(5у2 + 3y - 1)

Multiply the three terms by y

5y^2 * y + 3y * y - 1*y = 5y^3 + 3y^2 - y

Multiply the three terms by - 2

-2*5y^2 -2*3y - 2*-1

-10y^2 - 6y + 2

Now combine the like terms

5y^3 + 3y^2 - 10y^2 - y - 6y + 2

5y^3 - 7y^2 - 97y + 2

4x - y = -2 --------------------(I)

2x + 3y = 13 --------------------(II)

Multiply equation (I) by 3 and then add

(I)*3 12x - 3y = -6

(II) 2x + 3y = 13 {Now add and so y will be eliminated}

14x = 7

x = 7/14

x = 1/2

Plugin x = 1/2 in equation (I)

2 - y = -2

-y = -2 - 2

-y = -4

y = 4

Answer:

x=1/2

y=4

Step-by-step explanation:

4x-y=-2

-y=-4x-2

y=4x+2

2x+3y=13

2x+3(4x+2)=13

2x+12x+6=13

14x=7

x=1/2

y=4x+2

y=4(1/2)+2

y=2+2

Y=4

Shayla is going to paint a wall. The wall is 23 feet long by 8 feet high. A gallon of paint costs $11 and covers 320 square feet of area.

If the wall requires two coats of paint, what is the minimum cost of painting Shayla's wall?

Answers

Answer:

$12.65

Step-by-step explanation:

Given that the wall is 23 feet long and 8 feet high.

As the wall is rectangular, so the area of the wall,

A=23x8=184 square feet.

As a gallon of paint costs $11 and covers 320 square feet of area, so

Cost of paint for 1 square foot area = $ 11/320 per square foot.

Cost for 1 coat of paint = $ (11/320)x184

Cost for 2 coat of paint = $ (11/320)x184x2= $ 12.65

Hence, cost requires for 2 coats of paint is $ 12.65.

Danielle is making a quilt with triangles and squares. There are 4 colored triangles inside each square. The base and height of each triangle is x + 4 inches as shown. Which polynomial represents the area of the colored triangles in square inches?

Answers

Answer:

[tex](2x^2+16x+32)\ \text{sq. inches}[/tex]

Step-by-step explanation:

b = h = Base = Height of triangle = [tex](x+4)\ \text{inches}[/tex]

Area of one triangle

[tex]A=\dfrac{1}{2}bh=\dfrac{1}{2}(x+4)(x+4)[/tex]

There are 4 colored triangles so total area of the triangles is

[tex]4A=4\times \dfrac{1}{2}(x+4)(x+4)\\\Rightarrow 4A=2(x+4)^2\\\Rightarrow 4A=2(x^2+8x+16)\\\Rightarrow 4A=2x^2+16x+32[/tex]

The area of the colored triangles is [tex](2x^2+16x+32)\ \text{sq. inches}[/tex]
