I may be wrong, I think I remember how to do this. A straight line has an angle of 180, so y would be 133, making the area 55571.63u. (u = whatever unit is measuring the circle.) If x = 1/20 of the area, then the red area = 2,778.5u or 2,779u. I hope this helps, but I honestly don't remember how I would find x, and I don't want you to get the question wrong.
42.052
place value and digits:
4 = tens
2 = ones
0 = tenths
5 = hundredths
2 = thousandths
5 is in the hundredths place. To find if you round up or down, look at the digit to the right (thousandths in this case). It is a 2, which is less than 5, so you round down.
42.052 rounded to the nearest hundredth is 42.05
hope this helps
Answer:
Not proportional
Step-by-step explanation:
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solve for "y".
![\stackrel{f(x)}{y}=\sqrt[3]{x^5-3}\implies \stackrel{\textit{quik switcheroo}}{x = \sqrt[3]{y^5-3}}\implies \stackrel{\textit{cubing both sides}}{x^3=y^5-3} \\\\\\ x^3+3=y^5\implies \sqrt[5]{x^3+3}=\stackrel{f^{-1}(x)}{y}](https://tex.z-dn.net/?f=%5Cstackrel%7Bf%28x%29%7D%7By%7D%3D%5Csqrt%5B3%5D%7Bx%5E5-3%7D%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bquik%20switcheroo%7D%7D%7Bx%20%3D%20%5Csqrt%5B3%5D%7By%5E5-3%7D%7D%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bcubing%20both%20sides%7D%7D%7Bx%5E3%3Dy%5E5-3%7D%20%5C%5C%5C%5C%5C%5C%20x%5E3%2B3%3Dy%5E5%5Cimplies%20%5Csqrt%5B5%5D%7Bx%5E3%2B3%7D%3D%5Cstackrel%7Bf%5E%7B-1%7D%28x%29%7D%7By%7D)
