0.9 as a percentage would be 0.9% it doesn't really change
No; a range value has two domain values.
Hello! For this question, you solve using order of operations, which you probably already have remembered as PEMDAS. Anytime a number is raised to the 0 power, that is equivalent to 1. 0.5^0 is 1. 250 * 1 is 250. x = 0 gives us the answer of 250. Now, let's solve for the number by the second power. 0.5² is 0.25. 250 * 0.25 is 62.5. x² gives us 62.5. Now, let's subtract the two numbers together. 250 - 62.5 is 187.5. Because the number is decreasing, the slope is negative, so the answer is -187.5. Your answer is correct.
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
