15% discount means H pays 100% - 15% = 85% of the original price
.85 * $ 35 = $ ...........
Maybe your Q is missing something?
This will work -1 -2 = -3 ?
There is one solution. There are infinitely many solutions. The solution is (0, 4)
Slope of first line y = x-3 m = slope = 1
Slope of second line ay = ax - 3a slope is also 1 (no matter what value of nonzero a is chosen)
the lines are parallel ....no solutions
26800 = 7300 ( 1+ .0775)n
26800/7300 = 1.0775n Solve for n ( you'll find it easiest to use LOGs)
Original arc length would be x / 360 pi 2r
now multiply x by 1.2 and r by 1.25
1.2x / 360 pi 2 r * 1.25 = 1/2 * 1.25 x/360 pi 2r
= 1.5 * original so 50% longer
Multiply numerator and denominator by (1 - 7i) to get
(9 + 37i) / 50 or 9/50 + 37i/50
or .18 + .74 i
When the rock hits the surface h = 0
0 = -t^2 +8t + 10 use quadratic formula a = -1 b = 8 c = 10
\(t = {-b \pm \sqrt{b^2-4ac} \over 2a}\) You will get TWO values of 't' ....throw out the negative value
1) the two angles labelled encompass 110 + 120 = 230 degrees of the circle
the other angle covers the rest 360 - 230 = 130 o
3.5 % interest componded 4 times a year
interst per period ( 3 months) in DECIMAL form = .035/4
5 year would be 5 x 4 = 20 periods
FV = future value PV = present value (1000)
FV = 1000 ( 1 + .035/4)20 That's it ....calculate away....
