Answer:

  d  Dilation by a scale factor of 2 followed by reflection about the y-axis

Step-by-step explanation:

In each case, the transformation is ...

  (x, y) ⇒ (-2x, 2y)

So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.

The transformations are ...

Answer:

y = -2x + 2

Step-by-step explanation:

I need the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5.

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5. Include your work in your final answer.

"parallel"means "same slope".

let's find, first, the slope of the given line: rewrite the equation in standard form,

that is -

y=-2x-0.5

This means the slope of the required line is "-2"

Now, just plugin the numbers into standard equation:

y=slope*x+intercept

you'll end up with

y=-2x+2

Answer:

The average speed is 1 meter per second

Step-by-step explanation:

Here, we want to calculate average speed

Mathematically;

Average speed = Total distance/Total time

In this case, the total distance traveled = 1400-200 = 1,200 meters

Total time taken = 20 minutes

Since 60 seconds = 1 minute; 20 minutes is 20 * 60 = 1200 seconds

So average speed = 1200 meters/1200 seconds = 1 meter/second

Answer:

The coordinates of the point, (x₂, y₂), 1/4 distance from A to B  is given as follows;

[tex](x_2, \ y_2) = \left (x_1 + \dfrac{x_3 - x_1}{4}, \ y_1 + \dfrac{y_3 - y_1}{4} \right)[/tex]

Step-by-step explanation:

The steps used to find the point, P, 1/4 of the distance from A to B is as follows

Let the coordinate of the point A = (x₁, y₁) and the coordinate of the point B = (x₃, y₃)

Therefore, the coordinates of the point, P, (x₂, y₂), is given from the following relationship;

The coordinates of P 1/4 distance from A to B = (x₂, y₂) = (x₁ + (x₃ - x₁)/4, y₁ + (y₃ - y₁)/4)

Where;

x₂ = x₁ + (x₃ - x₁)/4

y₂ = y₁ + (y₃ - y₁)/4

By plugging in the values for x₁, y₁, x₃, and y₃, we can find the coordinates of the point P, 1/4 of the distance from A to B

The coordinates of P 1/4 distance from A to B = (x₂, y₂) = (x₁ + (x₃ - x₁)/4, y₁ + (y₃ - y₁)/4)

thats the estimate

Answer:

The smaller Number = 15

The larger number = 67

Step-by-step explanation:

Let

The smaller number = x

The larger number = 5x - 8

The sum = 82

(5x - 8) + x = 82

5x - 8 + x = 82

6x - 8 = 82

Add eight to both sides

6x - 8 + 8 = 82 + 8

6x = 90

Divide both sides by 6

x = 90/6

= 15

Therefore,

The smaller number = x = 15

The larger number = 5x - 8

= 5(15) - 8

= 75 - 8

= 67

Step-by-step explanation:

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

= 2[x² + 6x + 8]

= 2x² + 12x + 16

Answer:

a) Standard Error = 0.010

b) 95% Confidence Interval = (0.0924 , 0.1316)

Step-by-step explanation:

a) The formula for Standard Error = √Sample Proportion (1 - sample proportion)/n

Standard Error = √p (1 - p)/n

We are told in the question that:

In a random sample of 400 people, 112 agree and 288 disagree. Estimate the standard error using 1000 samples

p = x/n

n = 1000 because we were told to use it instead of 400

x = number for people that agree = 112

p = 112/1000

p = 0.112

Standard Error = √p (1 - p)/n

= √0.112 (1 - 0.112)/1000

= √0.112 × 0.888/1000

= √0.099456 /1000

= √0.000099456

= 0.0099727629

Approximately to 3 decimal places = 0.010

Therefore, the standard error is 0.010

b) The Question above also asked that we solve for the 95% Confidence Interval

The formula =

p ± z × Standard Error

p = 0.112

z score for 95% confidence interval = 1.96

Standard Error = 0.010

Confidence Interval =

0.112 ± 1.96 × 0.010

= 0.112 ± 0.0196

0.112 - 0.0196

= 0.0924

0.112 + 0.0196

0.1316

Therefore, the 95% confidence interval = (0.0924 , 0.1316)

Part 1

---------------------------

Explanation:

Let's focus on evaluating [tex]f^{-1}(13)[/tex] first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5

This means f(5) = 13 and [tex]f^{-1}(13) = 5[/tex]. The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.

We can replace all of [tex]f^{-1}(13)[/tex] with 5 to go from [tex]f^{-1}(f^{-1}(13))[/tex] to [tex]f^{-1}(5)[/tex]

Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9

So f(-9) = 5 and [tex]f^{-1}(5) = -9[/tex]

Overall, [tex]f^{-1}(f^{-1}(13)) = -9[/tex]

===============================================

Part 2

---------------------------

Explanation:

Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13

This means f(-13) = 8 and [tex]f^{-1}(8) = -13[/tex]

The value of [tex]f^{-1}(f^{-1}(13))[/tex] is -9

The value of [tex]f^{-1}[/tex] (8) is 13

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,

From the table,

f(5) = 13

This can be written as,

[tex]f^{-1}[/tex] (13) = 5 _____(1)

f(-13) = 8

This can be written  as,

[tex]f^{-1}[/tex] (8) = 13 ______(2)

f(-9) = 5

This can be written  as,

[tex]f^{-1}[/tex] (5) = -9 _______(3)

Now,

[tex]f^{-1}(f^{-1}(13))[/tex]

= [tex]f^{-1}[/tex] (5)  [ from (1) ]

= -9         [ from (3) ]

Now,

[tex]f^{-1}[/tex] (8) = 13    [ from (2) ]

Thus,

[tex]f^{-1}(f^{-1}(13))[/tex] = -9

[tex]f^{-1}[/tex] (8) = 13
