Last 2 problems that were too difficult for me, please don't get mad at me for sending a lot.

Answer:
Question 1: Slope = feet
Question 2: Slope = 4
Step-by-step explanation:
Question 1:
The pitch of a roof is the inclination of that roof. The "slopiness" of the roof. Whether it is steep or not.
To know the pitch, we need to find the "RISE" over "RUN". That means the "height" from ground and the "length" from initial position.
The height is shown in the figure as 4 ft
The length is shown in the figure as 12 ft
The slope is the quotient of it.
Hence,
Slope = 4/12 = 1/3 feet
Question 2:
To find slope from table of points, we need 2 coordinate pairs in the form (x,y). Lets take the first two points.
(1,2)
and
(3,10)
The slope would be the change in y coordinates of both (2nd point y coordinate - 1st point y coordinate) DIVIDED by the change in x coordinates of both (2nd point x coordinate - 1st point x coordinate). So:
Change in y coordinates = 10 - 2 = 8
Change in x coordinates = 3 - 1 = 2
Thus,
Slope = change in y/change in x = 8/2 = 4
Slope = 4

Answer:
Step-by-step explanation:
think of the flight of a small rocket.. what does it seem like the parabola would look like? down means it looks like a cup or glass , upside down , up mean a cup or glass right side up.
when t = 0 the rocket is at 25, so that's the initial height
it's velocity is initially 200 m/s
put equation from std. form to vertex form
y = a + bx +c => y = a(x - h ) ^2 + k
h = -4.9 + 200t + 25 =>h = -4.9(t - 20.41)^2 + 2,065.82
(h,k) = (20.41 , 2065.82)
