HEY GUYS

ANSWER THIS QUESTION

Answer 1

Answer:

Option(A)

Step-by-step explanation:

Given points is P(4,3,5).

Note: The distance of the point (a,b,c) from y-axis will be perpendicular distance from (a,b,c) to y-axis whose coordinate will be (0,a,0).

∴ Distance = √a² + c².

Now,

Given points are P(4,3,5) and A(0,1,0)

Distance = √(0 - 4)² + (0 - 5)²

λ = √(-4)²  + (-5)²

λ = √16 + 25

λ = √41.

Then:

7λ² = 7(√41)²

     = 7(41)

     = 287.

Hope it helps!
