<em>Comment on the question</em>

This shows up again and again in domain problems, so is worth remembering. The value under the radical cannot be negative (but it can be zero).

if BA is extended all the way through A creating BF and A becomes the midpoint of BF, then what are the coordinates of F
gogolik [260]

Answer:

F(2x_A-x_B,2y_A-y_B)

Step-by-step explanation:

Let points A, B and F have coordinates A(x_A,y_A),  B(x_B,y_B) and F(x_F,y_F).

If BA is extended all the way through A creating BF and A becomes the midpoint of BF, then the midpoint A of the segment BF has coordinates:

\dfrac{x_B+x_F}{2}=x_A\\ \\\dfrac{y_B+y_F}{2}=y_A

Express coordinates of point F:

x_B+x_F=2x_A\Rightarrow x_F=2x_A-x_B\\ \\y_B+y_F=2y_A\Rightarrow y_F=2y_A-y_B

Hence,

F(2x_A-x_B,2y_A-y_B)

. A condo in Orange Beach, Alabama, listed for $1.4 million with 20% down and financing at 5% for 30 years. What is the monthly
vovikov84 [41]
Listed price = $1.4 million
Down payment = 20% of $1.4 million = 0.2 x 1,400,000 = 280,000
Amount left to pay = $1.4 million - 280,000 = $1,120,000
Present value of an annuity is given by PV = P(1 - (1 + r/t)^-nt) / r
where: PV = $1,120,000
r = 5% = 0.05
t = 12
n = 30 years.
1,120,000 = P(1 - (1 + 0.05/12)^-(12 x 30)) / 0.05
1,120,000 x 0.05 = P(1 - (1 + 1/240)^-360)
56,000 = P(1 - 0.2238)
P = 56,000 / 0.7761 = 72,148.83
Therefore, the monthly payment is $72,148.83

The sale price for a bicycle is $315 dollars. The original price was first discounted by 50% and then discounted an additional 1
Len [333]
This means that the bicycle was discounted in total by 60%, so $315 is 40% of the original price to get 40% to 100% youd multiply it by 2.5 so so the same to the price 315 x 2.5= 787.5
