Hi!
If I have done this correctly, then the answer is:
2 million is 80% of 2.5
That means that 20% of the water evaported.
The car cost $4,155 and she has $1,575 so $4,155-$1,575=$2,580as the balanced owed if she borrows the rest from her parents and has a one year to pay it off it will be paid off because her payments are $225 a month for one year at 225x12=$2,700 its a little over but it will be paid off
This is a geometric sequence with a common ratio of 2
an = a1 * r^(n - 1)
n = term to find = 21
a1 = first term = 0.05
r = common ratio = 2
now we sub
a21 = 0.05 * 2^(21 - 1)
a21 = 0.05 * 2^20
a21 = 0.05 * 1048576
a21 = 52428.80 <==== after working 21 days
:answer (x+5−4)(x+5+4)(x−4)
how i got it:
(x+5−4)(x−(−
2
2(5+4)
))(x−4)
