plato answer

Assume that the initial coordinates are (x,y) and that the dilated coordinates are (x',y').

The dilation is therefore:

(x,y) ............> (x',y')

Now, let's assume that the dilation factor is k.

Therefore:

x' = kx

y' = ky

Based on the above, all the student has to do is get the initial coordinates and the final ones and then substitute in any of the above two equations to get the value of k.

Example:

Assume an original point at (2,4) is dilated to coordinates (4,8). Find the dilation factor.

Assume the dilation coefficient is k.

(x,y) are (2,4) and (x',y') are (4,8)

Therefore:

x' = kx .........> 4 = k*2 ..........> k = 2

or:

y' = ky ..........> 8 = k*4 .........> k = 2

Based on the above, the dilation coefficient would be 2.

Hope this helps :)

Answer:

First you have to find the ordered pairs for the shapes. Then figure out how much the pre-image was multiplied by. The number it was multiplied by is your scale value.

Answer:

The two hidden numbers are 8 and 1.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is given by the sum of all its values divided by the number of values.

Mode of a data-set:

The mode of a data-set is the value that appears the most.

In this question:

4, 9, x, y, 8

Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:

4, 9, 8, y, 8

The mean of the five numbers is 6

This means that:

[tex]\frac{4+9+8+y+8}{5} = 6[/tex]

[tex]29+y = 30[/tex]

[tex]y = 30 - 29[/tex]

[tex]y = 1[/tex]

The two hidden numbers are 8 and 1.

Answer: C

Answer:

60 degrees

Step-by-step explanation:

a triangle degrees altogether is 180 degrees

80+40=120

so 180-120=60

Answer: Given In the Chart Below

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The key here is she wants to make "at least", implying that you have an inequality.  If she cecks the house 4 times plus the 2 overnight stays then she will have exactly 150, so that is the least needed to reach her goal.  So at least automatically turns it into an inequality.

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

Explanation:

To isolate s, we need to undo the division. We'll multiply both sides by 3

14 = s/3

3*14 = 3*(s/3)

42 = s

s = 42

-------

As a check,

14 = s/3

14 = 42/3 .... replace s with 42

14 = 14

We get the same thing on both sides, so this confirms we have the correct value of s.

Answer:

8:1

Step-by-step explanation:

Okay so the ratio from cocoa to sugar from the chart is 8:2. To simplify this you could multiply both sides by 2 which would get you 4:1 or 4. Now the question asks what is the ratio Leah will use when this is doubled. In order to do this you can multiply 4 by 2 which gets you 8. Or 8:1. Hope you understand :)

Answer:

C) $50.00

Step-by-step explanation:

$7.50 is the 15% discount

1% of the original price would be ($7.50 / 15)=0.50

100% of the original price would be 100 x 0.50 =  $50.00

Answer: The slope is 1/2 and there is no y intercept

Step-by-step explanation:

Answer:

y = 7.5

x = 7.5√3

Step-by-step explanation:

sin(30) = 1/2

cos(30) = √3/2

Above is rule

==>

y = 7.5

x = 7.5√3

Answer:

49x^14

Step-by-step explanation:

Answer:

See explanations below

Step-by-step explanation:

Sin 0 = x

0 = arcsinx

Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)

cos 0 = 1 (by punching the calculator)

tan 1 = 0.0174

All this values can easily be gotten directly from calculators

Step-by-step explanation: the tangent is 8/6 because it is the opposite (8) over the adjacent (6)

Step-by-step explanation:

Answer: 72 Miles In 90 Minutes

Step-by-step explanation: First, you have to divide both 15 & 12 by 15, (which represents minutes), and you get 1 over 0.8. Next, you multiply 1 over 0.8 times 90, which gibes you 90/72. There is your answer! I hope that you found this helpful.

Here is the equation below:

15/12 divided by 15/15 = 1/0.8 x 90/90 = 90 MINUTES/72MILES

21\deg 17'34" i thin k

Answer:

The zeros are 0, 4, 6.

The y-intercept is 0.

Step-by-step explanation:

f(x) = x^3 - 10x^2 + 24x

x^3 - 10x^2 + 24x = 0

x(x^2 - 10x + 24) = 0

x(x - 4)(x - 6) = 0

x = 0 or x - 4 = 0 or x - 6 = 0

x = 0 or x = 4 or x = 6

y-intercept:

Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.

You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).

Let x = 0.

f(0) = 0^3 - 10(0^2) + 24(0)

f(0) = 0

y-intercept: 0

Answer: Angle C: 137 degrees

The degree is 4

2. x^3 - 4x =0

3. x-1/2=0        x-2/3=0

Step-by-step explanation:

Answer:

Step-by-step explanation:

2x + 4 = 2(x + 2)

[tex]Area = \frac{1}{2}*b*h\\\\=\frac{1}{2}*(2x-1)(2x + 4)\\\\\\= \frac{1}{2}*(2x - 1)*2*(x + 2)\\\\= (2x -1)(x+ 2)[/tex]

= 2x *x + 2x* 2  + x*(-1) + 2*(-1)

= 2x² + 4x - x - 2

= 2x² + 3x - 2
