Answer:
y² = 36x
Step-by-step explanation:
Parabola opens right.
Thus equation is from; y² = 4ax
And focus is at (a, 0)
Since we are given focus at (9, 0),it implies that a = 9
Thus, equation of parabola is;
y² = 4 × 9 × x
y² = 36x
The general Formula for a decreasing Annuity is:

For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02
After substituting you can find value for R, rent.
False, 4-2(3+7) = -16 and 4-2•3+2•7= 12
