Answer:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

Answer:
2.7 s (1 d.p.)
Step-by-step explanation:
Use the <u>Constant Acceleration Equations</u> where:
- s = displacement in meters
- u = initial speed in m/s
- v = final speed in m/s
- a = acceleration in m/s²
- t = time in s (seconds)
Given:
- s = 55 m
- u = 11.8 m/s
- a = 6.39 m/s²
Rearrange the equation to equal zero:
<u>Quadratic Formula</u>
Use the quadratic equation to solve for t:
As time is <u>positive</u>:

Answer:
12.56
Step-by-step explanation:
8 times 3.14 is 25.12. Then 4 times 3.14 is 12.56. Finally, you take 25.12 - 12.56 and the answer is 12.56.
