QUESTION 2 (3 points) A cannonball shot from the top of a building
can be modeled by the following equation:
h = -16(t - 3)2 + 189
Where t is in seconds and h is in feet.
a. How high is the cannon? Consider how
this is the location of the cannon ball at
second 0. Show or explain your answer.
b. When is the cannonball at the highest point? Show or explain your answer.

the axial of symmetry

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
