The midpoint M of JK has coordinates 4, 3. Point K has coordinates 1, 5. Find the coordinates of point J.
- Debra use http://www.webmath.com/equline1.html
You want to find the equation for a line that passes through the two points:
(4,3) and (1,5).
put these into
and it will explain the maths involved
midpoint M so x increased 3 from point k so at point JK would have to have x as 7
point J should be 7,10.333333333333333333333333334
or 7, 10 and 1/3

What is the radius of a 3/4 acre circle (in feet)
Oh wow, lots of math going on here...
There are 4840 square yards in an acre and 9 square feet in a square yard (4840 x 9 = 43,560).
An acre is an old timers measurement used in agriculture...
it was 4 poles wide and 40 poles long. A pole is equivalent to sixteen and a half feet. So back then, an acre was a piece of farming land 660 feet long (220 yards or one eighth of a mile) and 66 feet wide (22 yards or one eightieth of a mile).
Acre is a measure of area, which would be square feet.
Feet are a measure of distance.
The best you could do is something like this:
An acre is 43, 560 square feet.
Draw/imagine a square or a rectangle that would cover that much area.
If it is a square, it would be (approximately) 208.7 feet on each side.
Its perimeter (the distance around it if you walk an imaginary fence around you acre-sized plot) would be 834.8 feet.
Trying to to figure out an acre of 'Circle' - hmmmmm???
Radius = 1/2 of Diameter
sorry, just can't wrap my head around this to come up with the correct equation.
maybe we can get lucky with some other brainiac taking what I did provide and come up with a solution for you?
Square - It would be 208.7 feet across if you walk across it, and the same if you walk the other way across it.
