The line y = mx bisects the area enclosed by the lines x = 0, y = 0, x = 3/2 and the curve y = 1 + 4x – x2. Find the value of m.
Given curve is
y = 1 + 4x – x2
y = 5 – (x – 2)2
Now, the area OABO
Hence, the area OABCDO
According to the question,
9m/8 = (1/2) . (39/8)
m = 13/6
Hence, the value of m is 13/6.
