A9x) = x^2 - 6x + 9 = (x - 3)^2
length of a side = x - 3
The equation for slope is:
(y2 - y1) / (x2 - x1)
-2 -(-7) = 5
-9 -(-1) = -8
Slope of the line:
5/-8 or -5/8
In this case we have an ARM fixed for 6 years and adjust after the initial first 6 years every 2 years after. The basic idea behind a ARM is that the interest changes periodically, but since our ARM is fixed for 6 years, our going to calculate the monthly payment during the initial period using the formula:
where
is the monthly payment
is the amount
is the interest rate in decimal form
is the number years
First we need to convert our interest rate of 4% to decimal form by dividing it by 100%:
We also know from our question that
and
, so lets replace those values into our formula to find the monthly payment:
We can conclude that the monthly payment during the initial period is $1071.58<span />
The length of JK rounded to the nearest hundredth is 4.72

9. The Law of Sines says a:b:c and are the same ratio.
The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL
choice b
10.
DEF and FEG are supplments, FEG=180-DEF=180-114=66
DEF and HEG are opposite angles, so congruent HEG=DEF=114
