Question

Find the angle (in degrees please) between vectors B= 5.0i - 3.4j + .9k and C = 2.9i + 6.7j.

Answer #1

A) Find the angle between the vectors 8i-j + 4k and 4j + 2k
B) Find c so that the vectors 2i-3j + ck and 2i-j + 4k are perpendicular
C) Find the scalar projection and the vector projection of 2i +
4j-4 on 3i-3j + k

Find the angle θ between the vectors (,) and (-2,-4).

1) Find the angle θ between the vectors a=9i−j−4k and
b=2i+j−4k.
2) Find two vectors v1 and v2 whose sum is <-5,
2> where v1 is parallel to <-3 ,0> while v2 is
perpendicular to < -3,0>

10. Find the angle between the vectors, to the nearest
degree.
1. a =< 6, −7 > and b =< −4, −2 >
2. a = 6i+ 2j and b = −4i + 8j

Find the angle between the vectors < 1, 2, –2 > and < 4
,0, –3 >.

Add the vectors A and B to find the resultant vector C
A: 124miles at 5 degrees North of East
B: 88 miles at 82 degrees North of East
Find the component vectors

Give the magnitude and direction of vector C.

Consider the two vectors, A and B, for which the length and
angle are given below. What would be the x and y components of the
the vector sum C = A + B? length of A = 3.606, angle A makes with
respect to x-axis = 236.31 degrees length of B = 4.243, angle C
makes with respect to x-axis = 45.000 degrees
Cx=
Cy=

What is the effect on the dot product of two vectors, if the
angle between the two vectors is fixed, but one of the vectors
doubles in length? or triples in length?
two explainations please

Add the two vectors to find the resultant vector C which is
equal to A +B
