If energy not transformed or changes than nothing will happen light bulb electrical energy will not converted into light energy and heat energy. ... The energy is not transformed into another form, it simply moves. It has a tendency to move, unless it is trapped, until it is released.

Given:

A dilation centered at the origin with a scale factor of 2 can be denoted

with the following notation:

[tex]D_2(x,y)=(2x,2y)[/tex].

To find:

The [tex]D_4[/tex] for point  A (-2, 3).

Solution:

If [tex]D_2(x,y)=(2x,2y)[/tex], then

[tex]D_4(x,y)=(4x,4y)[/tex]

Substitute x=-2 and y=3 in the above rule to find [tex]D_4[/tex] for point  A (-2, 3).

[tex]D_4(-2,3)=(4(-2),4(3))[/tex]

[tex]D_4(-2,3)=(-8,12)[/tex]

Therefore, [tex]D_4[/tex] for point  A (-2, 3) is (-8,12).

Answer:

  1 < 15 -2a < 7

Step-by-step explanation:

There are a couple of ways you can do this.

1) Put the minimum and maximum values of a into the expression to see what its corresponding values are:

  15-2a for a=4:

     15-2(4) = 7

  15-2a for a=7:

     15-2(7) = 1

Then ...

  1 < 15-2a < 7

__

2) Solve for a in terms of the value of 15-2a, then impose the limits on a.

  x = 15 -2a

  2a = 15 -x

  a = (15 -x)/2

Now, impose the given limits:

  4 < (15 -x)/2 < 7

  8 < 15 -x < 14 . . . multiply by 2

  -7 < -x < -1 . . . . . . subtract 15

  7 > x > 1 . . . . . . . . multiply by -1

  1 < 15-2a < 7 . . . . . use x=15-2a

Step-by-step explanation:

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

Explanation:

Let's label (0,7) as point C.

Plot points A and C on the same coordinate system.

Note that to go from A to C, we must do two things (in either order)

These two items will be replicated in either order to go from point C to point B.

The translation rule we follow is [tex](x,y) \to (x+6, y+1)[/tex] which is a mathematical way of saying "go right 6 and up 1". If we plug in x = -6 from point A we get to x = 0 which is the x coordinate of point C. Repeating this leads to x = 6, which is the x coordinate of point B.

Through similar arguments, we go from y = 6, to y = 7, to y = 8, when we hop from points A, to C, to B in that exact order.

Put everything together and we see that B is located at (6,8)

The diagram below provides a visual summary.

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

Extra info:

If we draw a line from point A to B, then point C will be on this line. Furthermore, AC = CB which can be proven using congruent triangles. Reflections preserve distance, meaning the distance from A to the mirror point C, is the same as from B to C as well. In short, we can say C is the midpoint of segment AB.

Answer:

C

Step-by-step explanation:

Use Δ ABC to find AB then Δ ABD to find DB

Δ ABC  is isosceles since ∠ CAB = ∠ CBA = 45° , then CB = CA = 2

Using Pythagoras' identity in Δ ABC , then

AB² = 2² + 2² = 4 + 4 = 8 ( take square root of both sides )

AB = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

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

Using the sine ratio in Δ ABD with the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{DB}[/tex] = [tex]\frac{2\sqrt{2} }{DB}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

[tex]\sqrt{3}[/tex] × DB = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

DB = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] ( multiply numerator/ denominator by [tex]\sqrt{3}[/tex] to rationalise denominator )

     = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]

     = [tex]\frac{4\sqrt{6} }{3}[/tex] → C

Answer:

Perimeter of the triangle = (12x - 9)

Step-by-step explanation:

Property of an equilateral triangle:

- All sides are equal in measure.

- All interior angles are equal.

Since, measure of one side of the triangle = (4x - 3)

And perimeter of a polygon = Sum of all sides of the polygon

Therefore, perimeter of the given triangle = (4x - 3) + (4x - 3) + (4x - 3)

                                                                      = (4x + 4x + 4x) - (3 + 3 + 3)

                                                                      = (12x - 9)

Perimeter of the triangle = (12x - 9)

Answer:

3 apples for 1.29

Step-by-step explanation:

If you divide 1.29 by 3, you will get 0.43 which means each apple then costs 0.43 each. This is less than 0.45 so it is the better value.

Answer:

$1.29 for 3

Step-by-step explanation:

The reason is that $0.45 per apple means for every apple, you have to pay $0.45. That eventually is going to start to add up. $1.29 for 3 means that you are paying $0.43 for 3, which means that you are saving money.

Answer: 180.36

Step-by-step explanation:

I wasn’t sure if the questions was saying each ball was 29.99 or the total of the soccer balls was 29.99 without tax.

How I got the answer:

29.99 was the cost per soccer ball and he needed 6 of them and the tax was 7% which equal up to 0.07.

29.99 times 6 = 179.94

0.07 times 6 = 0.42 (the more you buy the more the tax raises)

179 + 0.42 = 180.36

The total is 180.38

Answer:

top graph

Step-by-step explanation:

The graph of a proportional relationship is a straight line passing through the origin.

The only straight line graph passing through the origin is the top one

The graph on option A displays a proportional relationship.

Option A is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line on the graph is given as:

y = mx + c ____(1)

The graph on option A.

If the equation of a line is y = mx and the slope is a unit rate the graph shows proportional relationships.

We will select two points on the graph.

i.e

(2, 2) = (a, b) and (3.3) = (c, d)

Slope:

m = (d - b) / (c - a) = 3 - 2 / 3 - 2 = 1 / 1 = 1

Let (2, 2) = (x, y) and putting in (1) we get,

2 = 1 x 2 + c

2 = 2 + c

c = 2 - 2 = 0

c = 0

The slope of the line is 1

The equation of the line is y = x

Thus,

The graph displays a proportional relationship.

Option A is the correct answer.

Answer:

Where's the equation

Given:

A point is reflected across the y-axis. The reflected point is (3.5,6).

Jimmy says the original point is (3.5,-6).

To find:

Whether Jimmy's statement true or false

Solution:

If a point is reflected across the y-axis, then y-coordinate remains same but change the sign of x-coordinate.

[tex](x,y)\to (-x,y)[/tex]

If the reflected point is (3.5,6), then the original point must be (-3.5,6), which is not equal to (3.5,-6).

Therefore, Jimmy's statement is false.

Answer:

i. - 3a² + 2ab + b²

ii. 2c² + - 2cd + - 4d²

Step-by-step explanation:

i. First things first, you remove the parenthesis in both expressions to look like this:

a² − 3ab + 2b² - 4a² + 5ab − b²

Next, you add like terms.

(a² + - 4a²) + (- 3ab² + 5ab) + (2b² + - b²)

After adding these like terms, your answer would be:

- 3a² + 2ab + b²

ii. This one is pretty simply. But first, lets simplify by first removing the parenthesis to look like this:

c² - 6d² + c² - 2cd + 2d²

Then, combine like terms

(c² + c²) + (- 2cd) + (-6cd² + 2d²)

After that, your sum would be:

2c² + - 2cd + - 4d²

Hope this helps!

Answer:

see explanation

Step-by-step explanation:

i

(a² - 3ab + 2b²) + (- 4a² + 5ab - b²) ← remove parenthesis

= a² - 3ab + 2b² - 4a² + 5ab - b² ← collect like terms

= - 3a² + 2ab + b²

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

ii

(c² - 6d²) + (c² - 2cd + 2d²) ← remove parenthesis

= c² - 6d² + c² - 2cd + 2d² ← collect like terms

= 2c² - 2cd - 4d²

Answer:

y= 1/4x-2

Step-by-step explanation:

Let's use the two points we have to find the equation.

y = mx + b

-2 = m(0) + b

So b = -2

-1 = 4m - 2

4m = 1

m = 1/4
