Question:
Which of the following represents two lines that are coplanar and do not intersect?
A. Perpendicular
B. Skew
C. Parallel
D. Intersecting
Answer:
Two lines that are co -planar and do not intersect is Parallel.
Step-by-step explanation:
Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it. Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect
Answer:
C

I did this question in school
Answer:
8,146 x 121
Step-by-step explanation:
This is a problem in which you need to measure your understading of "orders of magnitude."
If the estimated answer is
that means that we are looking at a multiplication in the "order of" 
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have
that would be "of the order of"
times
. So the whole multiplication would "of the order of"
or near 
The correct answer, 8,146 x 121, is because it's "of the order of"
times
and the gives us the
we need.
Answer:
Erik's average speed exceeds the speed limit by 6.91 miles per hour.
Step-by-step explanation:
Let suppose that Erik travels at constant speed. Hence, the speed (
), measured in miles per hour, is determined by following equation of motion:
(1)
Where:
- Distance, measured in miles.
- Time, measured in hours.
Please notice that a hour equals 60 minutes. If we know that
and
, then the speed of Erik is:


Which is 6.91 miles per hour above the speed limit.
