Texts: Section 2.2 - The Quadratic Formula An object is thrown upward at a speed of 89 feet per second by a machine from a height of 8 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t² + 89t + 8. When will the height be 94 feet? In seconds Hint: List all of the solutions with commas between them. Round to one decimal place. When will the object reach the ground? In seconds

An object is thrown upward at a speed of 78 feet per second by a machine from a height of 19 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2 + 78t + 19. (Tip: approximate all numbers to two decimal places.) When will the height be 78 feet? When will the object reach the ground?

An object is thrown upward at a speed of 72 feet per second by a machine from a height of 19 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2 + 72t + 19 (Tip: approximate all numbers to two decimal places.) When will the height be 45 feet? When will the object reach the ground?
