Question

if (k, k^2) lies inside the angle made by the lines 2y - x = 0 and Y - 3x = 0 , the complete solution set of k is. (1) (1/2,3) (2) (3, 1/2) (3) [1/2 , 3] (4) [3 , 1/2 ]​

Answer 1

Answer:

(3)

Step-by-step explanation:

the lines 2y - x = 0 and Y - 3x = 0 intersect at (0,0)

slope m1 = 1/2 , m2 = 3

angle between them = arc. tan (3-0.5 ÷ 1 + 1.5) = 45 degrees

correct solution is (3) [1/2 , 3]
