Question Luca is in a culvert below street level. He launches an object at an upward velocity of 40 feet per second. Use Geogebra or Desmos to graph the situation using the formula y=−16t2+40t−5 . How far above or below street level is Luca's initial launching point.
To determine how far above or below street level Luca's initial launching point is, we need to find the y-intercept of the graph of the equation y = -16t^2 + 40t - 5.
To do this, we can plot the graph of the equation using Geogebra or Desmos. The graph will show the trajectory of the object launched by Luca.
After plotting the graph, we can see that the y-intercept of the graph is at approximately y = -5. This means that Luca's initial launching point is 5 feet below street level.
Therefore, Luca's initial launching point is 5 feet below street level.
