Answer:
Step-by-step explanation:
Given that ||v|| = 2 and ||w|| = 3, and the angle between v and w is 120 degrees
We know by definition of dot product and properties that
where t is the angle between them
Using this we find
(a) v·w =
(b) ∥2v+w∥
(c) ∥2v−3w∥
You can figure this out by doing a proportion:
4.5 pages x pages
---------------- = ---------------
36 minutes 60 minutes(1 hr)
*makes sure that because they are giving you time in minutes that you convert the hour to minutes. also you need to always remember to line up the same factors like in this case line up the pages and the time.
36x = 4.5(60)
36x = 270
x = 270/36
x = 7.5 pages
hope this helps :)
m =
add to both sides
m = - +
we require a common denominator for both fractions before adding
multiply numerator/denominator of - by 2
multiply the numerator/denominator of by 3
= - + =
Answer:
C
Step-by-step explanation:
Draw in <QOS. That's the central angle. It is also 60 degrees.
<R which has Q and S as its end points, = 1/2 the central angle (always) so <R = 30 degrees.
C
