Step-by-step explanation:

let (x,y) be coordinates of P.

[tex]PM=\sqrt{(-5-x)^2+(3-y)^2} \\PN=\sqrt{(2-x)^2+(4-y)^2} \\\frac{PM}{PN} =\frac{\sqrt{(-5 -x)^2 +(3-y)^2} }{\sqrt{(2-x)^2+(4-y)^2 } } =\frac{3}{2}\\4[(-5-x)^2+(3-y)^2]=9[(2-x)^2+(4-y)^2]\\4[25+x^2+10x+9+y^2-6y]=9[4+x^2-4x+16+y^2-8y] \\4x^2+4y^2+40x-24y+100+36=9x^2+9y^2-36x-72y+36+144\\4x^2-9x^2+4y^2-9y^2+40x+36x-24y+72y+100+36-36-144=0\\-5x^2-5y^2+76x+48y-44=0\\5x^2+5y^2-76x-48y+44=0[/tex]

4. A cluster tells you where there is a concentration of data values.

Step-by-step explanation:

makes the most sense

A cluster tells you where there is a concentration of data values. The correct answer would be an option (C).

The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.

A cluster on a scatter plot refers to a group of points that are closely located together. This indicates that there is a concentration of data values in that area of the plot, as opposed to being spread out evenly. This cluster can be seen visually as a group of points that are tightly packed together.

Thus, a cluster tells you where there is a concentration of data values.

Hence, the correct answer would be option (C).

Answer:

46800

Step-by-step explanation:

10x15x24x13=46800

Answer: A.

Step-by-step explanation: First you must think about how many miles is 9 kilometers. How many miles in 9 kilometers is 5.59234. And A is the closest to the numbers of miles Tristan rode his bike. The other questions would be wrong. It isn't the exact one because it's the closest, not exact. Hope that helps :).

A wheel on a bicycle has a radius of 8 inches. The distance it covers if the tire makes 2 full rotations will be equal to 100.48 inches.

The distance covered by the wheel on a bicycle can be determined by using the formula:

distance traveled = 2 x circumference of the wheel

Where 2 is the number of rotations.

The circumference can be found by using the radius of the wheel in the formula:

C = 2π(r)

C =2π(8)

C =16π

Distance traveled can then be found by:

distance traveled = 2x16π

distance traveled =32π

As π = 3.14

distance traveled= 32 x 3.14 = 100.48 inches

Therefore, the distance covered by the wheel on a bicycle is equal to 100.48 inches if the tire makes 2 full rotations.

7

Step-by-step explanation:

Answer: Seven

Explanation: I wrote the numbers down, then added/subtracted 2 from 4, 7 from 6, and 8 from 0, then added all the totals

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Hope this helps!!

13v + 9

Step-by-step explanation:

(7v + 6) + (6v + 3) ← remove parenthesis

= 7v + 6v + 6 + 3

= 13v + 9

Answer:

No she will not save enough money for her trip and she needs $122 more for her trip.

Step-by-step explanation:

Deborah requires $74 each day for 13 days trip

Total least amount needed for the trip = 74*13

                                                       = $962

Deborah's saving strategy : she saves $84 per month for 10 months

saved amount at the end of the 10th month = 84*10 = $840

840/10 = $84

This clearly shows she is not saving enough money for her trip. She needs $122 more to support the expense of her trip.

Timothy way

84*10= $840 is to be compared with 74*18 = $1332

This method is also not a feasible one for calculating Deborah's expenses of her trip.

Answer:

34

Step-by-step explanation:

I hope you can read this. It is the only way I could think of putting it up for you.

The first diagram is the given situation.

The second diagram asks you to ignore the 98 degree angle and extend the line making up the 116 degree angle until it hits the parallel line on your right. You can then find the supplement to the vertically opposite angle because angles on the same side of the transversal and are interior angles are supplementary. You should get 64.

The third diagram finds the supplement to the 98 degree angle (and yes the 98 degree angle is back in the picture again).  You should get 82

You now have 2 known angles in a triangle. The third diagram finds y and <4 to be 34 That's your answer.

Answer:

-1 + [tex]\frac{x}{7}[/tex]

Step-by-step explanation:

( 2/7x-6 ) - ( 1/7x - 5 )

First you should combine 2/7 and x, and 1/7 and x. You do this by "bringing the x up". This is how the expression looks now: (2x/7 - 6) - (x/7 - 5). Notice: when you have 1x you can just remove the 1 since it is implied. The next step is to apply the distributive property. The number we are distributing is -1 to (x/7 - 5). This is how the expression now looks like: (2x/7 - 6) - x/7 + 5. Notice: since 5 was already negative, when we multiplied it by a negative, it became positive. Now we can remove the parenthesis since they are no longer necessary: 2x/7 - 6 - x/7 + 5. The next step is to combine the fractions since they have the same denominator. This is how the expression will look like now: -6 + 5 + [tex]\frac{2x - x}{7}[/tex]. Now we should subtract x from 2x (remember x really just means 1x). This is what we have so far: -6 + 5 + x/7. Lastly, we should add 5 to -6. This is how the finished expression should look like: -1 + x/7.

Hope this was clear!

Step-by-step explanation:

7 - 3 = ? not 4 so sub it

Answer:

Ethan's entire statement is true because he is saying that 7-3=4 and that is correct. If you have seven of something and take away 3 of them then you have 3 left.

Step-by-step explanation:

Take 7 apples for example, if you take away 3 of the apples and then count the left over you will notice that you end up with 4. Also, In a subtraction problem the larger number goes first followed by the smaller number, so that the end result is not a negative number. Hope this helps you.
