Answer:
$875.39
Step-by-step explanation:
1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.
2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.

4) Round $875.38
Answer:
7
Step-by-step explanation:
Just put the numbers in order the find the number in the middle in the case that there are to numbers add the together then divide by 2
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)
