Answer:
1.190390345 degrees.
Explanation:
As stated in the problem that the angle between the two curves is also the angle between slopes of the two cures at the point of intersection, which is 1 (when we set two equation equal and solve for x).
We know, if you don't you could verify it for yourself and it will be a nice mathematical exercise for you, that when there are two lines with slopes and
then the angle between them and their two slopes has following relationship.
where
is angle between the two lines.
As it is clear that we can easily get the angle between the two curves if we know slopes at that point, which you will see in second is very straight forward to calculate.
Slopes are simply derivatives evaluated at the point of intersection and the two derivatives are 16x and
, substituting x =1 we get,
and
.
Now put and
in this relationship, rearrange and solve for angle, it will come out to be
= 1.190390345 degrees.
that is our angle that we want to know between the two cures at the point of their intersection.
Answer:
14 N and 2 N
Explanation:
We have two vectors:
a = 8 N
b = 6 N
When the two vectors are in the same direction, their resultant is simply given by the sum of the magnitudes of the two vectors. Therefore, we will have:
Vice-versa, when the two vectors are in opposite directions, we have to consider one of the two vectors as being negative: therefore, the resultant will be given by the difference between the magnitudes of the two vectors. Therefore, in this case, we will have:
