ANSWER
A(6,-4) and B(3,1).
EXPLANATION
The given vector is
The component form of vector w, is calculated by subtracting the terminal position vector from the initial position vector.
With A(6,-4) being the initial point and B(3,1) the terminal point,
Subtract the corresponding components.

Answer:
Step-by-step explanation:
Given the function:
f(x) =number of days it would take to complete the project
x =number of full-time workers.
The domain of a function is the complete set of possible values of the independent variable.
In this case, the independent variable is x, the number of full-time workers. We have shown that x cannot be zero as there must be at least a worker on ground.
Therefore, an appropriate domain of the function f(x) is the set of positive integers (from 1 to infinity).
