Question 1

1.

Question: How many of you felt like Martha when you tried to complete this assignment?

ME!!! OMG this was tough!

Well at first, but then Mrs. Boyd gave me some feedback and I found my way.

Thanks for the feedback Mrs. Boyd, but I'm still ready to throw my book.

Since I didn't really take the time to do the assignment, I have no comment. 🙈 

I GOT IT! 👍 

Question 2

2.

How many seconds did it take for the ball to reach the maximum height? (round to the nearest tenths place)--

HINT: (this is just asking for the x coordinate of the vertex point, so evaluate -b/2a..that will be your answer)

Question 3

3.

What is the maximum height of the ball? (round to the nearest tenths place)

Now take the number you got for the x-coordinate of the vertex in number 1 and substitute into the equation...that will give you the y-coordinate of the vertex point...which will be the max height)

Question 4

4.

How long was the ball in the air? (round to the nearest tenths place)

(to find how long it is in the air, use quadratic formula...evaluate both the + and - versions of the answer. One of the answers will be positive...that will be your answer)

Question 5

5.

(to find how long it takes to reach the ground, use quadratic formula...evaluate both the + and - versions of the answer. One of the answers will be positive...that will be your answer)

Round your answer to the nearest tenths place.
