Explanation:
a) see the attachment for a graph (red curve)
__
b) The piecewise defined function can be ...

__
c) The new cost function is ...

The charge is a flat $10 for any period up to 5 hours, then $1 per additional hour after that, prorated for partial hours. There is apparently no upper limit on parking time as there was with the original function. (The graph shown goes beyond 15 hours; the domain of the original C(x) is 0 to 12 hours.) For reference, the new cost structure is shown in blue in the attachment.
_____
<em>Additional comment</em>
Under the new structure, costs are significantly higher for short-term parking, and lower once the term exceeds 6 hours.
you do not give a value for PI so I am using 3.14
V=PI x r^2 x H
you know volume and radius so put those into the equation
525 = PI (3.14) x 5^2 x H
525 = 3.14 x 25 x H
525 = 78.5 x H
divide both sides by 78.5
6.687 = H
round off answer as needed 6.7cm or 6.69cm
NOTE : the answer may vary slightly depending on the value of PI used.
but this is how you calculate the height.
Hello!
Her first commision would have to be multiplied by 5% first, which would be 6,000 x .05
This would equal to $300.
The second part would be .075 x 6000.
This equals to $450
Then, .01 x 12,000
This equals to $120.
Add all commisions, 300+450+120
****$870 is the total commision she received. ****
I hope I did this right. It's my first time on brainly. Tell me if you got it. Sorry if I didn't help
