The function y = -16t+ 40 represents the height y (in feet) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground? Round your answer to two decimal places.

The water fountain shoots water from a height of 6 ft.

Step-by-step explanation: When looking at a Quadratic Function on a graph it looks like a U (this one would be a upside down U).  The top of that U is the Vertex. (keep in mind the question revolves around the X-Intersect)

A water droplet reaches its maximum height after 6 s IS WRONG

Talking about the VERTEX

It takes 6 s for a water droplet to rise and fall back to the ground IS WRONG

This is talking about the WHOLE Parabola

A water droplet reaches a maximum height of 6 ft. IS WRONG

This is also talking about the VERTEX

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
