Answer:

Step-by-step explanation:
This line has an x-intercept at y = 0, x = 2. (First statement is false.)
Its y-intercept is at x = 0, y = 2. (Second statement is false.)
The third statement is true, as adding the x- and y-coordinates should sum up to 2, as in the equation "x + y = 2".
The fourth statement is false, since this description would fit the equation x + y = 4.
Therefore the third statement is the correct one.
Answer:
2 m.
Step-by-step explanation:
T = 8.0 s is the period of the pendulum
g = 9.81 m/s^2 is the acceleration due to gravity
What you do is subtract 16.25 by 15.5
- you get 0.75
Then do 0.75/16.25
It is 0.04615384615
When you convert that into percentages it would be a 4.6153% rounded up to 4.62 percent error
