Answer:

The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.

Round 71290 to the nearest 10 what's the answer?
Aloiza [94]
71290 because the ones are 0 and zero is lower than 5 
so it wouldn't add anything to the tens 

the rule is if the number is more than 5+ it will add 1 to the next number
for example if we have this number 189 and we want to round it to the nearest 10 ..
we will see the ones place is it more than 5+ ? YEAH bcz its 9 ...
so 9 will add one to the tense and the answer will be 190 :) 

hope you got the point .

Find the length of each arc<br> r=13 ft x=90 degrees
VladimirAG [237]

Answer:

13\pi/2

Step-by-step explanation:

The formula of the circumference of a circle is 2\pi r.

The length of an arch can be found by using the ratio of circumference to the arc.

First, find the circumference of the circle:

2\pi *13=26\pi

Then you find the ratio:

The length of the arc is 90/360, which is 1/4, of the circumference.

Finally, find the length of the arc:

26\pi*1/4=(13/2)\pi or 13\pi/2

I hope this helps :)
