Determine the sum of the first 10 terms of each geometric series.
a) 4 + 12 + 36 + ...
Answers
Answer:
I think the sum of the first 10terms of each geometric series is
4x3=12
= 4+12
12x3=36
=4+12+36
36x3=108
=4+12+36+108
108x3=324
=4+12+36+108+324
324x3=972
=4+12+36+108+324+972
972x3=2916
= 4+12+36+108+324+972+2916
2916x3=8748
=4+12+36+108+324+972+2916+8748
8748x3=26244
=4+12+36+108+324+972+2916+8748+26244
26244x3=78732
=4+12+36+108+324+972+2916+8748+26244+78732=the sum of the geometric series which is = 118,096.
hope this helps I am not sure of the answer but I tried my best.

It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]

A baseball team won 16 games and lost 11. At this rate, how many games will it win in a 162-game schedule?
Answers
==========================================================
Explanation:
The team won 16 games and lost 11 so far. At this point in the season, they played 16+11 = 27 games total. Their win rate is 16/27.
Set this equal to x/162 which is the win rate for winning x games out of 162 played over the entire season.
Solve for x.
x/162 = 16/27
27x = 162*16 ... cross multiplication
27x = 2592
x = 2592/27
x = 96
The team would win 96 games if it kept the same winning rate going.
Notice that 16/27 = 0.5926 = 59.26% and how 96/162 = 0.5926 = 59.26% as well (both are approximate). This helps confirm we have the correct answer.
-------------------------
Here's another slightly longer way to solve. If you prefer the first method above, then ignore this section.
w = number of games won over the entire 162 game season
162-w = number of games lost over the entire season
w/(162-w) = win to loss ratio
16/11 = win to loss ratio after winning 16 games and losing 11
Setting those last two expressions equal to each other and solving for w gets us...
w/(162-w) = 16/11
11w = 16(162-w)
11w = 2592-16w
11w+16w = 2592
27w = 2592 ... this hopefully looks a bit familiar from before
w = 2592/27
w = 96 games won
Find AC if AB = 1, AC = 2x + 26, and BC = x + 16

2x-x=1+16-26
X= - 9

=2*-9+26
= - 18+26
