Question

Which is the distance between points A and B?

Answer 1

A. squared root of 5
B. squared root of 3
C. 2
D. squared root of 2

Answer 2

Distance = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Answer 3

i dont understand @Gators88

Answer 4

thats the distance formula between two points. even though this is in 3D, the two points are in the same plane...so you can eliminate a coordinate

Answer 5

y = 1 for both, so pretend its just (x, z) (x2, z2)

Answer 6

ohhh okay thank you @Gators88

Answer 7

youre welcome...and by same plane I should clarify I meant one that is perpendicular to the y-axis, eliminating it

Answer 8

yahh i understand
