QUESTION 4:
The volume of a rectangular box is 64 ft3. If the width is 3 times longer than the height, and the length is 9 times longer than the height, find the dimensions of the box. Define your variables then show all work using the equation editor. Write a sentence that explains your answer
QUESTION 5:
A model rocket is launched straight upward from the side of a 212-ft cliff. The initial velocity is 86 ft/sec. The height of the rocketh(t) is givenby: h(t)=-16t2 + 86t + 212
whereh(t) is measured in feet andtis the time in seconds. Use the quadratic formula to find the times (t)at which the rocket is 320 ft.above the ground. Round your answers to the nearest hundredth of a second.
