Answer:
The scouts hiked up the mountain in 1 mile.
Step-by-step explanation:
A relation can be a function if an x value is not paired with more than y-values.
The x and y values are flipped when finding an inverse.
So, if in the inverse function a y value is paired with more than one x values, this will mean that in the function an x-value was paired with more than one y-values.
Looking at the graph we can say that no y-value in the inverse is paired with more than one x values, so the original relation would be a function.
So the answer is TRUE
Answer:

Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 cm
Radius, r = 4 cm
Height of the cylinder, h = 16.8 cm
We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :

So, the surface area of the cylinder is 
40% as a fraction in simplest form would be 2/5.
