If X > 0 then X must be a positive number.  If Y < 0 then Y must be negative.  So the quadrant that contains Positive X values and negative Y values will contain the point that you are looking for.  This would be the fourth quadrant.

Polygon D is a scaled copy of polygon C using a scale factors of 6
Vladimir79 [104]

Answer: The area of the Polygon D is 36 times larger than the area of the Polygon C.

Step-by-step explanation:

<h3> The complete exercise is: "Polygon D is a scaled copy of Polygon C using a scale factor of 6. How many times larger is the area of Polygon D than the area Polygon C"?</h3>

 In order to solve this problem it is important to analize the information provided in the exercise.

You know that the Polygon D was obtained by multiplying the lengths of the Polygon C by the scale factor of 6.

Then, you can identify that the Length scale factor used is:

Length\ scale\ factor=k=6

Now you have to find the Area scale factor.

Knowing that the Length scale factos is 6, you can say that the Area scale factor is:

Area \ scale\ factor=k^2=6^2

Finally, evaluating, you get that this is:

Area \ scale\ factor=36

Therefore, knowing the Area scale factor, you can determine that the area of the Polygon D is 36 times larger than the area of the Polygon C.

Anyone know this ???...
Karolina [17]

Answer:

4250 children

Step-by-step explanation:

72-38=34 degrees

34 degrees therefore is 578 people

so, 1 degree is 17 people

There is 360 degrees in a circle so we must subtract the degrees of the men and female segments in order to know how many degrees children takes up:

360-72-38=250

250x17=4250 children

Let a be the sum of the last four digits and let b be the last digit of your 8-digit student id. (example: for 20245347, a = 19
pav-90 [236]

Using the student id given above, a = 19 and b = 7

Average speed for the first 54 km = 48+a km/h

Plug a = 19

Average speed for the first 54 km = 48+19 = 67 km/h

Average speed for remaining 86 km = 43-b km/h where b = 7

Average speed = 36 km/h

Average speed of entire journey = total distance / total time taken

speed = \frac{distance}{time}  and  time = \frac{distance}{speed}

Time taken to cover 54 km = \frac{54}{67} hr

Time take to cover 86 km = \frac{86}{36} hr

Total time taken = 3.2 hours.

Total distance = 86+54= 140 km

Average speed of the entire trip = \frac{140}{3.2} = 43.75 km/ h

It would be the fourth choice, 3y.
Remember, to get the product of two numbers, you must multiply them together.
Difference=subtraction
Sum=addition
Quotient=division
