A farmer is putting up a fence for her animals. She orginally had the fence enclosing a square was 18ft by 18ft. Suppose she uses the same amount of fencing to enclose a circular area. What is the area of the circle?

Answers

First look: More than 324 square feet :)
Now, $l=2\pi*r$ which means that $r=(l)/(2\pi)$ . But l is the original perimeter, 4 times the side of the square, that is, 72 ft. So, $r=(72)/(2\pi)=(36)/(\pi)$
Now, the area of that circle is $A=\pi*r^2=\pi*(1296)/(\pi^2)=(1296)/(\pi)$ , which is about 412.5 square feet. It's true, that's more (that's the most you can actually get with that amount of fence :) )

Write an equation of the line that is:a) parallel to the line y=4x+1, and that passes through point (2,3)
b) parallel to the line 2y-6x=9, and that passes through point (-2,1)
c) parallel to the line y=4x+3, and that has the same y-intercept as the line y=5x-3
d) parallel to the line -1/2x, and that has the same y-intercept as the line 2y=7x+6
e) perpendiclar to the line 2y-4x=8, and that passes through point (6,-6)
f) perpendicular to the line 2y-5x=15, and has an x-intercept of 3

Mikhail has a savings portfolio containing $12,000, of which $3,000 is invested in CDs. His friend, Ivan, has $2,000 invested in CDs, and this investment is proportional to Mikhail's. How much money is in Ivan's savings portfolio?

Answers

Mikhail has $3.000 of his $12.000 invested in cd's, which is 3.000/12.000 = 1/4 of his total savings portofolio. Ivan too has 1/4 of his total savings portofolio invested in cd's, which is $2.000. So Ivan's total savings portofolio is 4 x $2.000 = $8.000
