Vector v has a magnitude of 23 and a direction angle of 270 degrees. write this vector as a linear combination of the standard unit vectors i and j. v=248.5i+15.5j v=248.5i-105.5j v=-23i v=-23j

Solution:

we are given that

Vector v has a magnitude of 23 and a direction angle of 270 degrees.

we have been asked to find vector as a linear combination of the standard unit vectors i and j.

The vector as a linear combination of the standard unit vectors i and j can be written as below

Hence the correct option is -23j.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
