Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)
check the picture below.
so, those are the points, now, the line of symmetry, the red one, is the line that will cut the vertex is half and will be perpendicular to the opposite side.
now, the slope of the black line we can just get it off the grid, notice the rise and run, rise/run = 6/6 = 1.
now a perpendicular line to that one will have a negative reciprocal slope, thus
so the slope of that perpendicular line will be -1, so we're really looking for the equation of a line whose slope is -1 and runs through -6,3.
![\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{3})\qquad \qquad \qquad slope = m\implies -1 \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-3=-1[x-(-6)] \\\\\\ y-3=-1(x+6)\implies y-3=-x-6\implies y=-x-3](https://tex.z-dn.net/?f=%20%5Cbf%20%28%5Cstackrel%7Bx_1%7D%7B-6%7D~%2C~%5Cstackrel%7By_1%7D%7B3%7D%29%5Cqquad%20%5Cqquad%20%5Cqquad%20%20slope%20%3D%20%20m%5Cimplies%20-1%20%5C%5C%5C%5C%5C%5C%20%5Cstackrel%7B%5Ctextit%7Bpoint-slope%20form%7D%7D%7By-%20y_1%3D%20m%28x-%20x_1%29%7D%5Cimplies%20y-3%3D-1%5Bx-%28-6%29%5D%20%5C%5C%5C%5C%5C%5C%20y-3%3D-1%28x%2B6%29%5Cimplies%20y-3%3D-x-6%5Cimplies%20y%3D-x-3%20)

For the answer to the question above, I'll use one-time computing.
<span>Interest = Principal * rate * (loan duration/time unit) </span>
<span>= $1500 * 4.9% * (125 days/365 days) </span>
<span>Normally, a bank or accountant WOULD NOT use your method of rounding in the middle of the calculation but rather would round the final result. This is the normal way to handle all such mathematical processes. However, for your question, </span>
<span>= $1500 * 4.9% * 0.34 </span>
<span>= $24.99 </span>
<span>If you don't do the rounding in the middle of the calculation, the answer is $25.17.
I hope this helps.</span>
