https://www.mathhomeworkanswers.org/232693/find-the-earliest-interception-and-latest-interception
My teacher wants us to solve this using excel. I'll leave out the extra stuff. "Your radar provides the following information about the incoming warhead at time of detection (t=0 seconds): vertical hight= 490,000 feet (about 93 miles) with an incoming vertical velocity= -4,107 feet/second. You know the following information about your Patriot missiles located at sea level: initial upwards velocity if 6,115 ft/second. You also know that each Chinese missile is typically designed to explode at 3 miles (about 16,000 feet) above the ground... armed with this information and using quadratic mathematics and MS Excel, answer the following questions: 1. If your missiles require a minimum of 10 seconds to launch from t=0, calculate the time and altitude of earliest interception. 2. What is the latest time (as measured from t=0) that you can launch the Patriots and still expect to intercept the missile...?" He wants us to put everything, including graphs, in a word document with the answers to the questions. I'd like to know how to get the functions to enter into excel. The early and late Patriot launches are confusing...Word Problem Answershttps://www.mathhomeworkanswers.org/232693/find-the-earliest-interception-and-latest-interceptionSun, 27 Nov 2016 20:52:58 +0000how do i solve x/5+3x/4=38
