PLZ HELP! 20 POINTS!

agasfer [191]

Answer:

a) The error is that, the initial value is n=1 NOT n=3

b) The sum is $a_n=a_{n+1}+5=192$

c)The explicit formula is $a_n=5n+3$

The recursive formula is $a_n=a_{n+1}+5$ ,

Step-by-step explanation:

The given arithmetic series is 8 + 13 + ... + 43.

The first term is $a_1=8$ , the common difference is $d=13-8=5$

The nth term is given by:

$a_n=a_1+d(n-1)$

We substitute the values to get:

$a_n=8+5(n-1)\\a_n=8+5n-5\\\\a_n=3+5n$

To find how many terms are in the sequence we solve the equation:

$3+5n=43\\\implies 5n=43-3\\5n=40\\n=8$

The summation notation is $\sum_{n=1}^8(3+5n)$

The error the student made is in the initial value.

It should be n=1 NOT n=3

b) The sum of the arithmetic series is calculated using:

$S_n=\frac{n}{2}(a+l)$

We substitute o get:

$S_8=\frac{8}{2}(5+43)$

$S_8=4(48)$

$S_8=192$

c) The explicit formula we already calculated in a), which is $a_n=3+5n$

The recursive formula is given as:

$a_n=a_{n+1}+d$

We substitute d=5 to get:

$a_n=a_{n+1}+5$

Answer:

4s + g = 76.00

4(9)+ g=76.00

36+g=76.00

36-36+g=76-36

g=40 /4

g=10

Step-by-step explanation:

106.00-30=76.00

s= shoes 9.00

g= games

4s + g = 76.00

4(9)+ g=76.00

36+g=76.00

36-36+g=76-36

g=40 /4

g=10

The sales tax in New York is 8.25%. About how much will a $66.00 pair of shoes cost, including sales tax?

Airida [17]

Answer:

Step-by-step explanation:

66.00 x 1.0825 = 71.445 rounded to $71.45

You take 8.25% and divide it by 100 which will give you 0.0825 by adding a 1 this will get you the sales tax and original amount.
