An observation deck extends 119 feet out above a valley. The deck sits 69 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h=−16t^2+69. How long will it take for the object to be 5 feet above the valley floor?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

there are infinitely many solutions.
