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)
Answer:
y=4x+5 is 4 and 4/1
the next one is y=8x+3
hope this helps
Step-by-step explanation:
Two sets of 2+3 is greater
The equation is 18.1 - x = -0.7
18.1 - -0.7 =
18.1 + 0.7 = 18.8
18.1 - 18.8 = -0.7
Florida’s 3-month temperature is 18.8 degrees C warmer than Montana’s.
I don't know if you still need help. but the answer is the first one.
