111) 5:4
112) 3.6
113) -4
114) 0.3 units down, 0.4 units to the left
Answer:

Step-by-step explanation:
1. rewrite the equation in standard form: 
2. find (h,k), the vertex. the vertex is 
3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2
4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a distance p from the
y coordinate which is at
. Set up the equation:

5. substitute and solve:


hope this helps, ask me questions if you still don't understand.
Without speeding up it would take 5 1/3 seconds.. not sure if it speeds up in the question?
Mean= (5+6+5+6+9)/5= 7.2 coins
Explanation: The mean is the average of a data set. Add the numbers from the data set and divide by how many numbers.
Angles 1 and 2 are supplementary angels because they form a line.
Angles 1 and 2 are adjacent angles because they share an interior ray and they have a common vertex.
