Anewsboy purchases papers at 10 cents and sells them at 15 cents. however, he is not allowed to return unsold papers. if his daily demand is a binomial random variable with n = 10 , p = 1 3 , approximately how many papers should he purchase so as to maximize his expected profit?

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

m∠a is 90°

m∠b is 40°
