Equation of the circle
(x-h)² + (y-k)² = r²

(h,k) = (-3,6) - coordinates of the center of the circle
r=2 - radius of the circle

(x-(-3))² + (y-6)² = 2²
(x+3)² + (y-6)² = 4

The best way to approach this problem is to look at the graph of the given function. Replace values of x from 1 to 24 to indicate the numbers of hours in a day. As seen on the graph, there is only one point where the port is at high tide. That would be at 1:00 am. 

Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.

How do you work out a percentage
Anni [7]
You can find percentages with a calculator, or without a calculator:

Non-calculator:
To find a percentage of a number without a calculator, you divide the number by the percentage's number equivalent. For example, to find 10% of a number you divide by 10, to find 25% of a number you divide by 4 (because 25% is 1/4 of 100%), to find 50% you divide by 2, and 1% is dividing by 100, etcetera. You can then use the initial percentage's to find more complex percentages, so to find 30% you would divide by 10 and then multiply that by 3, and 75% would be dividing by 4 and multiplying that be 3.

Calculator:
If you have a calculator when you are asked to find the percentage, there is a much simpler way. All percentages have a decimal equivalent because you can picture all percentages as being fractions over 100, and therefore if you divide that number by 100 you get its decimal. On a calculator, if you multiply a number by a decimal multiplier, you get that percentage. For example, if you want to find 25% of a number on a calculator, you would multiply that number by 0.25.

I hope this explains things well enough! Let me know if I missed anything out :)
