Quadratic equation applications pdf

Notice as well that this is NOT the second solution without the negative this time, unlike the first example. We know the time spent working together 2 hours so we need to work rates of each machine. Here are those computations. In fact, they will need to so we can solve for it! Plugging into the word equation gives,.

Machine B will need 4. Again, unlike the first example, note that the time for Machine B was NOT the second solution from the quadratic without the minus sign. Notes Quick Nav Download. You appear to be on a device with a "narrow" screen width i.

Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.

Example 1 We are going to fence in a rectangular field and we know that for some reason we want the field to have an enclosed area of 75 ft 2. We also know that we want the width of the field to be 3 feet longer than the length of the field. What are the dimensions of the field?

Example 2 Two cars start out at the same point. One car starts out driving north at 25 mph. Two hours later the second car starts driving east at 20 mph. How long after the first car starts traveling does it take for the two cars to be miles apart? Example 3 An office has two envelope stuffing machines. Working together they can stuff a batch of envelopes in 2 hours. Using the quadratic formula and simplifying that answer gives,. So, it looks like the car A traveled for Notice as well that this is NOT the second solution without the negative this time, unlike the first example.
