To find how many seconds it took for the egg to reach the ground, we need to find the x-value when y = 0.
Setting y = 0 in the given function -2x + 80 = 0.
Simplifying the equation, we get -2x = -80.
Dividing both sides by -2, we get x = 40.
Therefore, it took the egg 40 seconds to reach the ground.
Jeffrey was practicing for an egg drop challenge with the engineering club. Each participant creates a device to hold an egg that is dropped from the top of a building. The egg that doesn’t break wins. The height of Jeffrey’s egg above the ground can be found using the function y=-2x+80, where x is the time in seconds that the egg has been in the air.
The graph below is provided in case you want to graph the function. It is intentionally blank.
