The formula for the length of a polar curve is<span>∫<span>r2+(dr/dθ<span>)2 from a to b. 

In this case, dr/d</span></span></span>θ is the derivative of the function r which is equal to -cos (theta/2) * sin (theta/2)<span> which is equal to -1/2 cos theta. Since there are no limits defined, we leave the formula as it is but one can use the calculator if there are limits present already</span>

What is m,y-intercept and the y
amid [387]

Answer: The slope is 500 and the y intercept is 0.

Step-by-step explanation:

To find the slope we need to find the rise and divide it by the run. The y intercept will be when x is equal to 0. And when x is 0 y is also zero because it cuts through the origin meaning that the y-intercept is  0.

The line rises up by 1000 and run by 2 to the right.

Slope :  1000/2 = 500

The slope is 500.

Need help with this question.​
sergejj [24]

Answer:

12 and 93.

Step-by-step explanation:

Let the grandsons age be x then Mr. Roger's age = 8x - 3.

Five years ago the grandson's age was x-5 and Mr Rogers was 8x - 8 years old , so:

8x - 8 - (x - 5) = 81

8x - 8 - x + 5 = 81

7x = 81 + 8 - 5 = 84

x = 12.

So the grandson is 12 and Mt Rogers is  8*12 - 3 = 93.

22 is 44% of what number?
Vladimir79 [104]
So 22 is 44% of something
22=44% of x
'of' means multiply
22=44% times x
percent means parts out of 100
44%=44/100
22=44/100 times x
22=44x/100
multiply boht sides by 100
2200=44x
divide both sides by 44
50=x
the number is 50

Suppose that 13 inches of wire costs 52 cents. At the same rate, how much (in cents) will 34 inches of wire cost.
dimulka [17.4K]

Find price per inch:

0.52 / 13 = 0.04 per inch.

Multiply cost per inch by inches:

0.04 x 34 = 1.36

It will cost $1.36 for 34 inches.
