Question

In a system of Cartesian coordinates are given points A = (0, 0) and P = (3, h). What's the alternative which its expression represents the distance from point P to point A as a function of h?

a) d = 9 + h
b) d= 9 + h²
c) d = 9 + 6h + h²
d) d = h + 3

Heeelp!

Answer 1

d^2 = sqrt( (0-3)^2 + (0-h)^2 )

Answer 2

I meant d = sqrt of all that

Answer 3

umm d =sqrt(9+h^2)

Answer 4

d = sqrt(9 + h^2)

Answer 5

your options are wrong

Answer 6

weird... I only have these options :/ why sqrt guys?

Answer 7

apply pythagorus theorem, to undestand the formula correctly
