The vertices A B C of a triangle are (2,-1,-3) (4,2,3) and (6,3,4) respectively. Show that vector AB=(2,3,6) and AC=9.

Try this option:

1) vector AB=(2;3;6).

2) |AC|=9.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
