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
<u>Answer:</u>
44 is 4/5 out of 55 (44/55 = 4/5)
<u>Step-by-step explanation:</u>
55 can be divided into fifths.
1/5 = 11 or 11/55
11 x 4 = 44
Hopefully this helps :3 Sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3
-Bee~
x < 4
given x - 1 < 3 ( add 1 to both sides )
x < 4
or x ∈ ( - ∞, 4 ) ← in interval notation
You could probably just put (1,0) but if not then my best guess would be (0.1,0)
