Need help with geometric sequences 30 points

Mathematics
1 answer:
NeTakaya3 years ago
8 0

Answer:

a_{n} = 6(5)^{n-1}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

a_{n} = 6(5)^{n-1}

$947.50 - $189.50 = ?<br>Am I not smart or what?
VashaNatasha [74]
<span>   $947.50
</span> - $189.50
_________
$758.00

So, to do this first we start at the far right and go to the left.

   $947.50 - $189.50_________
   $      .00
0-0= 0
5-5= 0

You then bring down the decimal.

   $947.50 - $189.50_________
    $   8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
         17
   $93-7-.50         -7- = This means the 7 has been canceled out and turned  - $189.50                        into the 17 above _________         8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.

          17
   $8-3--7-.50         -7- and -3- = This means the 7 has been canceled out                                                         and turned into the 17 above 
  - $189.50                        _________    $ 58 .00
So then, 13-8=5. Finally 8-1= 7

   $947.50
 - $189.50
_________
$758.00

F(x)=3x+5/x, what is f(a-2)
grin007 [14]

Replace x with the binomial a - 2.

f(a - 2) = [3(a - 2) + 5]/(a- 2)

f(a - 2) = [3a - 6 + 5]/(a - 2)

f(a - 2) = [3a - 1]/(a - 2)

f(a - 2) = (3a - 1)/(a - 2)

Done.
