Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct

Answer:
Using mental math, the approximate tip to leave for a bill of $81.79, if you tip 15% would be?
c.$12.30
Step-by-step explanation:
10% is $8.179, then 5% is a half of this sum, i.e. $8.179:2=$4.0895
3. 15%=10%+5% and in $ it is $8.179+$4.0895=$12.2685 that is nearly $12.30.
