Answer:
The function is non-proportional.
Step-by-step explanation:
If the function was proportional, when the number of hours spent riding the bicycle is equal to 0, the total cost of renting the bicycle would also be 0. In other words, the function would be proportional if y=0 when x=0. However, this is not the case.

Plug 0 into the equation as x

When 1 bicycle has been rented for 0 hours, the customer still has to pay 10 dollars just for renting it. When x=0, y=10. This means that the function is non-proportional.
I hope this helps!
1.6 is = to 1 6/10 = 1 3/5
so 1.6 in simplest form is 1 3/5
Hope this helps! :D
The lenght would be 12*4 is 48
Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is

. We will fill in accordingly:

. Solve for r to get that
It's not the volume of the ramp, it's the angle.
anyways here's how to use trig to find the answer:
Tan <A= opposite/ adjacent
Tan <A= 5.0/ 37.4
<A= tan-1 (5.0/ 37.4)
<A= 7.61 degrees.
