Part 2
this activity will you meet these educational goals:
you will create a function to model a fireworks show and examine the attributes of the function.
you’re in charge of planning a fireworks show. the company you hire proposes using fireworks called mortar fireworks. these fireworks are placed in a tube that sits on the ground or a flat surface and are shot from the tube with an initial velocity that propels them into the sky.
mortar fireworks have two fuses that are lit at the same time. the first fuse burns fastest and causes the initial force that launches the firework into the sky. the second fuse takes longer to burn. when the second fuse reaches the middle of the firework, the firework explodes and we see the light show in the sky. this second fuse does not add any extra propulsion to the firework while it’s in the air.
you plan to have the company light the fireworks from the ground. based on information provided by the company, you’ve determined that the fireworks will have an initial velocity of 192 feet/second.
the formula for the vertical motion of an object is h = -16t2 + v0t + h0, where h is the height of the object, h0 is the initial, or starting, height, v0 is the initial velocity, and t is the time in seconds.
using the equation representing the height of the firework (h = -16t2 + v0t + h0), algebraically determine the extreme value of f(t) by completing the square and finding the vertex. interpret what the value represents in this situation.

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
