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)
It´s <span> x = 2
I´m positive that is right </span>
The solutions to your problem I believe is 4 and -6.
Answer:
The domain for graph 1 is all real numbers, the range is y >= 0.
The domain for graph 2 is x >= 0, the range is y >= 0
Step-by-step explanation:
Graph 1: The x values are infinite for the graph, the y values will always be above zero and continue to be infinite.
Graph 2: The x values start at 0 and go to the right for infinity, the y values start at 0 and continue to infinity.
