So the answer is D
Answer:
Step-by-step explanation:
4.0 | <u> 4.50 </u> | -0.3(4.0) + 6.71 = <u>5.51</u> | 4.50 - 5.51 = <u>-1.01</u>
5.9 | <u> 5.50 </u> | -0.3(5.9) + 6.71 = <u>4.94</u> | 5.50 - 4.94 = <u>0.56</u>
Answer:
D

The magnitude of each vector is the Pythagorean sum of its components.
a. |v1| = √(2² + (-6)²) = √40 = 2√10
|v2| = √((-4)² + 7²) = √65
b. To make each vector into a unit vector, divide each component by the vector's magnitude.
u1 = v1/|v1| = (2/(2√10), -6/(2√10))
u1 = (√10/10, -3√10/10)
u2 = v2/|v2| = (-4/√65, 7/√65)
u2 = (-4√65/65, 7√65/65)
