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.

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
