Step-by-step explanation:
Given that a window is in the form of a rectangle surmounted by a semicircle.
Perimeter of window =2l+\pid/2+w
Or
To allow maximum light we must have maximum area
Area = area of rectangle + area of semi circle where rectangle width = diameter of semi circle
Hence we get maximum area when i derivative is 0
i.e.
Dimensions can be
Answer:
+6x-16
Step-by-step explanation:
(x+8)(x+−2)
=(x)(x)+(x)(−2)+(8)(x)+(8)(−2)
=x^2−2x+8x−16
=x^2+6x−16
