Answer:
p >= 1/3
Step-by-step explanation:
to solve the inequality you must start by subtracting 8 to all sides
you will get -3p <= -1
then you divide everything by --3
you end with p >= 1/3
your answer is p >= 1/3
The area for a semi circle in Cartesian coordinate system with the flat edge against the x-axis is:A=∫0r2−x2√∫−rrdxdy
Bounding limits for x are from -r to r. And for y, this comes from the equation for a circle:x2+y2=r2
Solve for y:y=±r2−x2−−−−−−√
But since we are only dealing with a semi circle, we can always look at the positive answer.
To convert to a polar coordinate system, we used some equations you have probably seen:x=rcosθy=rsinθdxdy=rdrdθ
The substitute to convert to polar coordinate system:A=∫0π∫0rrdrdθSolve this for the area.A=πr2/2
To find the x coordinate of the centroid:x=1/A∫∫xdxdyorx=1/A∫0π∫0rrcosθ(rdrdθ)Solve and you will find x = 0 which intuitively makes sense.
Similar for the y coordinate of the centroid:y=1/A∫∫ydxdyory=1/A∫0π∫0rrsinθ(rdrdθ)Solve and you will find y=4r/3π
This means the centroid of a semicircle is at: (0,4r/3π)
Answer:
I’m not sure what the height or the width is, or the perimeter, I’m not sure if it’s a prism, but it should be 1.7 ?
Step-by-step explanation:
18.7-17= 1.7 ...
Monday through Friday is 5 days.
Multiply the cost of lunch by number of days:
3.25 x 5 = $16.25
Subtract the total he spent on lunch from what he started with for money:
20 - 16.25 = 3.75
He had $3.75 left.
Answer:
hi:) you can use an app called photomath, you just take a picture of any math problem and it gives you the answer and shows all the work:) thats what I use.
