28,800 seconds =3 workers
9,600=1
So
9,600(5)=48,000
48,000/60=800 minutes
Or
800/60=13.333 hours
You'd want to use a vertical line test.
1st image: Every vertical line cuts the graph at at most one point
2nd image: The vertical line x = 1 cuts the graph at more than one point
3rd image: The vertical line x = 1 cuts the graph at 2 points
4th image: The vertical line x = -2 cuts the graph at 2 points
Hence, graph 1 (1st image) is a function.
Step-by-step explanation:
Use the formula D2 = X^2 + Y^2 to find the squared distance between two points. If the two points have coordinates (-3, 7) and (1, 2), then the difference between 7 and 2 is 5, and so Y = 5. For example, if X = 4 and Y = 5, then D2 = 42 + 52 = 41. Thus, the square of the distance between the coordinates is 41.
y^2 means (y) x (y)
Answer:
the answer is 15 because you have to do the problem in the parentheses first then multiply by 5
