Hey there,
Length (diameter)= 7 + 7
= 14 cm
Circumference = 2 x pi x r
= 2 x pi x 7
= 14 pi

Hope this helps ^_^

An arithmetic sequence has this recursive formula:

maxonik [38]

An arithmetic sequence can be expressed as explicitly or recursively

The explicit formula of the sequence is $a_n = 11 - 4n$

<h3>How to determine the explicit formula</h3>

The recursive formula is given as:

$a_n = a_{n -1} - 4$

$a_1 = 7$

Substitute 2 for n in $a_n = a_{n -1} - 4$

$a_2 =a_1 - 4$

This gives

$a_2 =7 - 4$

$a_2 =3$

Calculate the common difference (d)

$d = a_2 -a_1$

$d = 3- 7$

$d = -4$

The explicit formula is then calculated as:

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

This gives

$a_n = 7+ (n - 1)*-4$

Expand

$a_n = 7+4 - 4n$

$a_n = 11 - 4n$

Hence, the explicit formula of the sequence is $a_n = 11 - 4n$

A hairstylist schedules 1/4 hour to trim a customer's hair and 1/6 hour to style the customer's hair. The hairstylist planst to

allsm [11]

Well 1/4 = 3/12 and 1/6 = 2/12 so 2/12 + 3/12 is 5/12 then do 4 1/3 divided by 5/12 which is 13/3 divided by 5/12 which is the same as 13/3 x 12/5 which is 156/15 which is 10.4 but since people can’t be decimals it is 10 per day but since it’s asking for 5 days it would be 50 customers
