**If our phone with 10 gigabytes of free storage downloads a game that takes of 76 megabytes, how much free storage is left?****Describe the process of subtracting numbers in scientific notation and give the solution.****Discuss other place we frequently see scientific notation in real life?**

**The quadratic equations are common in many times of applications. The quadratic equation gives us a powerful tool to use to solve them. If one throws a ball down from a high cliff, the distance it travels can be modeled by the equation: ****𝑑****=−9.8****𝑡****2−15****𝑡****+100 where t is the time in seconds and d is the distance in meters. **

**At what time will the ball hit the ground?****You will get two answers because this is a quadratic equation. Do both make sense? (Explain in detail***Why*or*Why not*).
