No it doesn't rise as x grows really large.

Finance charge is equal to:
daily balance*A*P*R*billing cycle/365
db 0.1204 30/365 = 5.71
db = 577.01 (I am rounding every answer, and keeping the number in my calculator, things won't work out exactly if you calculate using my numbers)Manipulate the formula for mean:
average = total/amount
577.01 = total/30
total over 30 days = 17,310.22Set up an equation with our information:
606.40x + 55.25(30-x) = 17,310.22
551.15x = 16,652.72
x = 28.4
The balance was $606.40 for 28 days, so she paid on the 29th.
<span>As for this problem, we will
first establish that the length of the flower bed be represented as x, the
width of the flower bed be represented as x/2 ,and the area of the flower bed
be taken as it is since it is given. We then follow the formula for area which
is length multiplied to width which is:<span>
A = LW
we then
substitute them
34 square
feet = x (x/2)
now all
we need to do is find x first.
34 square
feet = x squared / 2
now do a
cross multiplication
68 square
feet = x squared
then get
the square root of both sides
8.246
feet = x
Since x
is equal to the length of the flower bed, all we have to do to get the width of
it is to divide it by 2. So...
W = x/2
W = 8.246
feet / 2
W = 4.123
feet
<span>And since
the problem asked it to find the width of the flower bed to the nearest tenth
of a foot, the answer would be 4.1 ft.</span></span></span>
