Nathan earns 9.75 dollars in <u>one</u> hour, and you want to figure out how many he makes in <u>thirteen and a half</u> hours. To do this, just multiply 9.75 by 13.5.
9.75*13.5 is 131.625. However, money only goes to the hundredths place, which means there are only 2 decimal places. This means you should <u>round 131.625 to the hundredths place</u>, which makes 131.63.
Quadratic equations are also used when gravity is involved, such as the path of a ball or the shape of cables in a suspension bridge. A very common and easy-to-understand application of a quadratic function is the trajectory followed by objects thrown upward at an angle.
