Answer:

A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller).

Step-by-step explanation:

Dilations can also reduce the size of shape. The picture below demonstrations a dilation of 12 Any time that the scale factor is a fraction, the image will get smaller.

It's always easier to understand a concept by looking at specific examples with pictures, so I suggest looking at the dilation examples below first...before you try to internalize the steps listed below and that explain the general formula for dilating a point with coordinates of (2, 4) by a scale factor of 12.

Answer:

for 15 the answer is 61 and

16 the answer is 82

Step-by-step explanation:

First you need to know that these are vertically opposite angles and that the vertical opposite angles are always the same.

therefore in qn 15.

- the 125 degrees angle is vertically opposite to the 64 + x angle therefore we make an equation

64 + x = 125 (then minus 64 on both sides)

(64 - 64)+ x = 125 - 64

x = 125 - 64

x = 61

the same goes for qn 16.

85 + x = 167 (then minus 85 in both sides)

85 - 85 + x = 167 - 85

x = 167 - 85

x = 82

Answer:  [tex]x \le 9[/tex]

x is less than or equal to 9

on a keyboard you would write x <= 9

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

Explanation:

We have a closed circle at x = 9. This means we include this endpoint as part of the shaded region. We will have "or equal to" as part of the inequality sign.

We also have "less than" as part of the inequality sign since we shade to the left. Values in the shaded region (eg: 2, 3, and 4) are either less than 9 or equal to 9.

So that's why the graph represents [tex]x \le 9[/tex]

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

Extra info:

If you want to write that in interval notation, then you would say [tex](-\infty, 9][/tex]

The curved parenthesis says to exclude the endpoint. We can't ever reach infinity so we cannot possibly include it as a number.

The square bracket says to include the endpoint.  

Answer:

40

Step-by-step explanation:

The spinner gives you 5 choices.

The die gives you 8 choices

Answer: The total number of choices is 5* 8 = 40

it is saying that You spin a spinner with five equal spaces so, we have 5

roll an eight - sided die so, we have 8

then, it is saying that

How many possible outcomes are in the sample space

= 5 × 8

= 40

Based on the First image, the correct option is the fourth image while based on the second image, the correct option is the fourth image also.

Given that the pre-image is rotated in the direction of the arrow as seen an the first image.

It is required to find the image formed also in that given direction.

Based on the fact that the arrow is rotating counter-clockwise, we get that, the shape of the pre-image will also rotate upwards towards the left hand side of the image shown.

So, based on the options (Taking the 1st image as pre-image), we have,

The fourth image where the shape is at the highest height will be the the fourth image after rotating the pre-image.

Answer:

Step-by-step explanation:

The marked-down price is ...

  $50 × (1 - 20%) = $50 × 0.80 = $40

Barry gets a 10% discount on that price, so his discount is ...

  $40 × 0.10 = $4

Barry pays $40 -4 = $36.

__

Barry would be correct if the "additional 10% off" were based on the original price, but it isn't. It applies to the already-discounted price.

Answer:

The radius is multiplied by 5.

Step-by-step explanation:

The radius of the circle is multiplied by 5 times the radius of the old circle

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the radius of the old circle be r₁

Now , the area of the old circle A₁ = π( r₁ )²

And , let the radius of the new circle be r₂

where area of new circle = 5 x area of old circle

And , A₂ = 25A₁ = π( r₂ )²

On simplifying , we get

25A₁ / A₁ = π( r₂ )² / π( r₁ )²

( r₂ )² = 25( r₁ )²

On further simplification , we get

Taking square roots on both sides of the equation , we get

r₂ = 5r₁

Therefore , the value of r₂ = 5r₁

Hence , the new radius is 5 times the old radius of circle

Answer:

y = 11/4

Step-by-step explanation:

(1/4)⁻³ x (4)⁸ = (1/4)^-4y

4³ x 4⁸ = 4^4y

=> 11 = 4y

=> y = 11/4

The coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).

The coordinates of the quadrilateral WXYZ is W(-4, 5), X(-1, 4), Y(-6, 1) and Z(-8, 3).

We need to find the coordinates of the figure W'X'Y'Z', in which figure WXYZ is rotated 90° clockwise.

To rotate the figure 90° clockwise about a point, every point (x,y) will rotate to (y, -x). Let's understand the rotation of 90° clockwise about a point visually. So, each point has to be rotated and new coordinates have to be found.

Now,

W (-4, 5)→W' (5, 4)

X (-1, 4)→X' (4, 1)

Y (-6, 1)→Y' (1, 6)

Z (-8, 3)→Z' (3, 8)

Therefore, the coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).

Answer:

1. x = 6.1

2. x = 95.5

3. x = 0.51

4. x = 94.4

5. x = 5.3

Step-by-step explanation:

I did this in degree mode, with SOH CAH TOA. The * sign represents the degree sign in my explanation.

1. sin 34* = 3.4/x   ->  x(sin34*) = 3.4  ->  x = 3.4/(sin34*) -> 6.1

2. cos 57* = 52/x  ->  x(cos57*) = 52  -> x = 52/cos57* = 95.5

3. tan63* = 1/x  -> x = 1/tan63* = 0.51

4. tan58* = x/59  -> 59(tan58*) = x  -> x = 94.4

5. cos55* = x/9.3  -> 9.3(cos55*) = x  -> x = 5.3

Answer:

80 days

Step-by-step explanation:

Start off by making the two equations.

t = total cost

d = days

Robert Downey Jr.'s equation would be:

t = 8d

Chris Evans' equation would be:

t = 6d + 160

Now, set them equal to each other:

8d = 6d + 160

Then, solve for d:

8d = 6d + 160

Subtract 6d from both sides:

2d = 160

Divide both sides by 2:

d = 80 days
