Polygon: Heptagon
Vertices: 7
Sum of angles: 900°
--------------------------------
Solution:
158 + 120 + 139 + 121 + 125 + 126 = 789
900 - 789 = 111°

Answer:
For Review: Planning Ahead and Contracts Quick Check... these are the answers...
1) B. Yes, you want to begin saving at least 25 years before you plan to retire
2) D. all of the above
3) $2,341.27 per month realized income
4) Your housing and fixed expenses are $702.38 per month do you want to have a four month emergency fund and save it over a nine month period of time how much do you need to save per month?
Answer #4) $312.17 /month
Step-by-step explanation:
702.38 * 4 = 2,809.52 How much you will need to save for 4 months worth or expenses.
Now divide by 9 because that is how many months you will take to save up...
2,809.52 / 9 = 312.17
Answer) $312.17 per month, for 9 months to save 4 months worth or expenses.
Answer:
Since the focus is at (-6,-11) and the directrix is at y=9:
The vertex is halfway between the focus and the directrix, so the vertex is at (-6,-1). (Draw this on graph paper if that doesn't make sense.)
The general form (conics form) of a parabola: 4p(y-k)=(x-h)^2 (vertex is (h,k) and "p" is the distance between the focus and vertex (or between vertex and directrix)).
(h,k) = (-6,-1)
p = 10 (distance between focus and vertex), so 4p = 40.
Therefore:
40(y+1)=(x+6)^2
Or if you need to rearrange to "vertex form": y=(1/40)(x+6)^2 - 1
