Let the line

x=-1

divide the area of the region \left\{(x, y): 1+x^{2} \leq y \leq 3-x\right\}

in the ratio

m: n, \operatorname{gcd}(m, n)=1

. Then

m+n is equal to $Let the line x=-1 divide the area of the region \ (x, y): 1+x^ 2 ≤ y ≤ 3-x\ in the ratio m: n, gcd(m, n)=1 . Then m+n$

Options

D26

Correct answer

A. 27

Step-by-step solution

$Let the line x=-1 divide the area of the region \ (x, y): 1+x^ 2 ≤ y ≤ 3-x\ in the ratio m: n, gcd(m, n)=1 . Then m+n$

\dfrac{m}{n} = \dfrac{\int_{-1}^{1} [(3-x) - (1+x^2)] \, dx}{\int_{-2}^{1} [(3-x) - (1+x^2)] \, dx} = \dfrac{20}{7}

\therefore m + n = 20 + 7

= 27
