A
this is an arithmetic sequence whose n th term ( explicit formula) is
=
+ (n - 1 )d
where d is the common difference and
the first term
here d = 10 - 8 = 8 - 6 = 6 - 4 = 2 and
= 4, hence
= 4 + 2(n - 1 ) = 4 + 2n - 2 = 2n + 2 → A
Answer: 18.75 lb.ft
Step-by-step explanation:
Given
Force required to stretch spring 8 in. is 18 lb
it can be written

Work done in stretching from its natural length to 10 in.

If in 2000 there were 430 folksk, 2010 is 10 years later, thus t = 10
The inequality equation would be 482.75+82.25x1250 <span>subtracting the amount that Hannah already has from the goal would amount to 767.25, therefore she only needs to save up to equal or more than this amount. Dividing this by 82.25 would then give us how many months this would take equal or greater than 9.33 months.</span>
