Answer:
$185.17
Step-by-step explanation:
The monthly dollar amounts saved here form a geometric progression, since each new amount is derived by multiplying the previous amount by 1.10. This 1.10 is r, the common ratio. The first term is $24 and there will be 5 more terms (June through December is 6 months).
The general formula for individual terms of a geometric series is A(n) = A(1) + r^(n - 1).
Here, with A(1) = $24 (the first term), r =1.10 and n = 6, we'd get $38.65 (the 6th and last term). Following the same procedure, we'd find that the 6 terms will have the values $24, $26.40, $29.04, $31.94, $35.14. $38.65.
Finally, we add these up. We get the sum $185.17.
Fortunately, there's a formula that makes the calculations go much faster: "sum of a geometric sequence." This formula is:
1 - r ^n
a(1)*--------------
1 - r
Here, a(1) = $24 and r = 1.10, and so the sum of the first 6 terms of this geometric sequence is
1 - 1.10^6
$24*---------------- = $185.17
1 - 1.10

Answer
The slope is 2
Step-by-step explanation:
V = <span>πr^2h
V = </span><span>π . 6^2 . 11
V = </span><span>π . 36 .11
V = 396</span><span>π
if you use </span><span>π = 3.14 then
V = 396 x 3.14 = 1243.44
answer: </span>396π or 1243.44
Hello there! :)
First, we. must make sure that variables are on the left side of the equation and numbers are on the other side.
-x=-12-11
-x=-23
x=23
Hope it helps!
