Answer:
3
Step-by-step explanation:
The lights and pole form a right triangle. The question gives the hypotenuse as 5 and one side length as 4.
Use the Pythagorean theorem: .
Plug in what you are given:
b = 3
Or you could recognize that it was a pythagorean triple: 3, 4, 5
If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope
The equation of the graph is given as:
The above equation is a linear equation, which is represented as:
Where m represents the slope of the linear equation.
By comparison, we have:
i.e. the slope of the equation is -0.14
When -0.14 is replaced with 2, the equation becomes
And the slope of the new equation is
2 is greater than -0.14, and 2 is positive.
This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope
