Pretty sure it's a, because you only want a small sample size and few people. Also you want many trials because you need to know of it works. Was <em>I right?</em>
Answer:
18.25m
Step-by-step explanation:
Subtracting the two Vectors we have
= 3ti - 4ti + t^2j - - t^2j
=- 1ti + 2 t^2j
= The distance between the lines is given by
= Squaroot of ( ( -3)^2 +( 2(3)^2 )^2
= Squaroot of 9 +324
= Squaroot of 333
= 18.25m
Answer:
x = 1/3
Step-by-step explanation:
-4(3x − 2) = 6x + 2
Distribute
-12x +8 = 6x +2
Add 12x to each side
12x-12x+8 = 6x+2+12x
8 = 18x+2
Subtract 2 from each side
8-2 = 18x+2-2
6 = 18x
Divide each side by 18
6/18 = 18x/18
1/3 =x
