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

Step-by-step explanation:
Answer:
Point P = (-9,11)
Step-by-step explanation:
Point M: (1,3) X and Y have the 2 on the bottom right of them
Midpoint N: (-5,7)
Point P: (X*2, Y*2)
( 1 + X*2 3 + Y*2 )
( _______ ________ ) = (-5 , 7)
( 2 , 2 )
( 1 + X*2 )
( _____ ) = -5
( 2 )
Then multiply the left equation above by 2, and that cancels out the 2 being
divided on the bottom. Also, multiply the -5 by 2 and you get -10
1 + X*2 = -10
+1 +1
__________
X*2 = -9
X = -9
( 3 + Y*2 )
( ______ ) = 7
( 2 )
Then multiply the left equation above by 2, and that cancels out the 2 being divided on the bottom. Also, multiply the 7 by 2 and you get 14
3 + Y*2 = 14
-3 -3
_________
Y*2 = 11
Y = 11
