Distance from focus to vertex=distance from vertex to directix
from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)
for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix
vertex=(6,1.5)
ditance=0.5
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5
Answer:
20260275
Step-by-step explanation:
the question is same as selecting 4 things from 150 things
= C(150,4). (nCr formula)
=[150×149×148×147]÷[4×3×2×1]
= 49×75×149×37
= 20260275
The Answer: A = $ 13,421.56
Formula A=P(1 + r/n)^(nt) A=10000(1+0.059/12)^(12(5)) = $ 13,421.56
V = the future value of the investmentP = the principal investment amountr = the annual interest raten = the number of times that interest is compounded per yeart = the number of years the money is invested for
I think it would be around -8.
Hope it helps!
