To understand the function better, let's convert it from polar coordinates to cartesian coordinates. The relation between those coordinates are
Our function is
If we multiply both sides by r, we have
The square of the radius is equal to the sum of the squares of the cartesian coordinates
Using this identity, we can rewrite our function as
Completing the square, we can rewrite our function as
This is a equation of a circle.
19,840 pages. You must multiply 20 pages by 31 days which gives you a product of 620 pages. This is the amount of pages each student reads in the month of January. Then, you must multiply 620 pages by 32 students and get a product of 19,840 pages in all.
Answer:
please write. question properly
1) change 65% to a decimal = .65
2) .65 • 60 = 37.2 questions need to be right
3) since she got 42 correct, that is greater than 37.2, so she passed.
OR
1) 42/60 = 0.7
2) 0.7 to a percent = 70%
3) since she got a 70% on the test, she passed.
