You have a wire that is 42 inches long. You want to cut it into 2 pieces. You want one piece to be 2/5 the length of the other. How long should the 2 pieces be?
A package drops. The height of the package above the ground at any time is modeled by the function
h(t)= -5t2-30x + 675, where h(t) is the height in meters, and t is the time in seconds. How long will it take the package to hit the ground? Please show your work and explain what you did because I want to learn it and not just copy.
