Jack bought a new boat for £12 500 The value, £V, of Jack's boat at the end of n years is given by the formula
V = 12 500 < (0.85)"
(a)At the end of how many years was the value of Jack's boat first less than 50% of the
value of the boat when it was new?

answer: a

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
