Find radians per second      then multiply by 60

2.4 rev/ 3 s   x  2pi R/rev = 5.0265 R/s    

now multiply by 60 to get R/min

a=0;b=0;c=0;d=0;p=0; cycle:n=a*1000+b*100+c*10+d;if(n<2021 and a+b+c+d==10, goto loop, goto next); loop:printn,", ",;p=p+1; next:d++;if(d<10, goto cycle, 0);d=0;c++;if(c<10, goto cycle, 0);d=0;c=0;b++;if(b<10, goto cycle,0);b=0;c=0;d=0;a++;if(a<10, goto cycle,0);print"Total = ",p

OUTPUT: There are 2020 positive integers that Wendy can choose from. There are 120 positive integers whose digits sum up to 10.

So, the probability is: 120 / 2020 = 6 / 101 which are relatively prime. m + n = 6 + 101 =107.

From the formula, the circumradius is 48/5.

a=0;b=0;c=0;d=0;p=0; cycle:n=a*1000+b*100+c*10+d;if(n%2==0 or n%5==0 or n%10==0, goto loop, goto next); loop:printn,", ",;p=p+1; next:d++;if(d<10, goto cycle, 0);d=0;c++;if(c<10, goto cycle, 0);d=0;c=0;b++;if(b<10, goto cycle,0);b=0;c=0;d=0;a++;if(a<10, goto cycle,0);print"Total = ",p

OUTPUT = 6,000 such integers.

Find the three lengths of the sides by using the distance formula and then show that these numbers fit in the Pythagorean Theorem.

To find the area, you now know the lengths of the two non-hypotenuse sides of the triangle; one of these will be the height of the triangle, the other will be the base -- use the usual area formula for the area of a triangle.

Thank you so much!!! I retried it using your method and have gotten it to work now. I think I was confsued because my teacher had said that to graph a negative r value, you do \(\left|r\right|\), and make \(\theta\) go clockwise, but maybe I misunderstood them.

Remember that a negative r value means that the distance must be measured "through the pole".

Therefore, if you have an angle that puts the point into the 2nd quadrant, you must put the point in the 4th quadrant.

This is true for all points ... quadrant 1 points get placed into quadrant 3; quadrant 3 points get placed into quadrant 1,

and quadrant 4 points get placed into quadrant 2.

I'll bet (but not too much, 'cause I'm cheap) that, because the full graph is done by the time you get to 180o (or pi),

and repeats the picture again, you're putting the second half of the points in quadrants 2 and 3, when they should

be placed in quadrants 1 and 4.

Think about what the negative r-value means.

In that case, I have already watched that video, and still do not understand. It goes over the graphing part very quickly, and I do not get it's explanation of having a negative r value in an \((r,\theta)\) coordinate.

The first video is what I think Melody wants you to see. As to Mathway, it is blocked on my browser :/

Thank you for the help!

Unfortunately, I can not get the "view steps" in Mathway to work without making an account, which costs money. Additionally, the first link does not bring me to a video, just to google search :/

Here is a site that will definitely help.

I am very rusty on this topic so I can't help at all without doing some 'homework'

Here is a video I am watching that might help with an introduction.

Example:

How many integers less than or equal to 20 are divisible by 2? 5? or 10?

20/2 = 10

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

20/5 = 4

5, 10, 15, 20

20/10 = 2

10, 20

10 + (4/2)_{because every 2 numbers there is a even number} - 2 = 10

Now apply the same to 10,000

I would draw this on a graph and then prove that the quadrilateral is a parallelogram by using slopes.

The slope of AB equals the slope of CD and the slope of AD equals the slope of BC; therefore,

since the opposite sides are parallel, this is a parallelogram.

Look at the answer I put on your original

Me too!   I don't tolerate panhandlers...... it only encourages them 

try watching this

n = nickels                         value = 5n

q = quarters = 27-n            value = 25 (27-n)       summed = 395

5n + 25(27-n) = 395    solve for n  the number of nickels =.........

3x² + 4x + 12  =  0 

Using the quadratic formula with  a = 3   b = 4   c = 12:

x  =  [ -4 +/- sqrt( 4² - 4·3·12 ) ] ( 2·3 )  =  ( -2 + 4sqrt(2) ) / 3      ( -2 - 4sqrt(2) ) / 3

[ ( -2 + 4sqrt(2) ) / 3 ]²  +  [  ( -2 - 4sqrt(2) ) / 3 ]²  

=  ( 36 - 16sqrt(2) ) / 9  +  ( 36 + 16sqrt(2) ) / 9  =  8

i would have $12.30 by the end

Depends on how much you gave away !

If you gave what each asked

12.30 - 2.00 - 2.00 - 5.00  = $  3.30

rectangle = 8x 15 m^2

semi circle = 1/2 pi r^2                       ( r = radius = 4 m  )

Add them together = .....

I just saw this question back a little.

You said you did not want the answer any more.

Actually you said that since you had been ignored for all of a couple of hours you had now lost interest.

If you want to repost questions then please just give the address of the original and ask people to answer on the original.

There is no reason why questions should be answered over and over again. 

There is even less reason when the same person is asking each time.

.85x = 170

x = 170/.85 = .........
