Answer:
A)
Step-by-step explanation:
uv = u1v1 + u2v2 = (1/3)*18 + 4*(-3/2) = 6 - 6 = 0
Because uv=0, these 2 vectors are orthogonal.
The total number of people in the family that generates 20 loads of laundry in a week is 10.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the number of people and x represent the number of laundry loads.
From the table:
y = (1/2)x
For 20 loads:
y = (1/2) * 20 = 10
The total number of people in the family that generates 20 loads of laundry in a week is 10.
