A 10 feet long ladder was leaning against the brick wall as in the picture. The bottom end of the ladder was skidding away at the rate of 3 feet per second. To be uniformly done in solving, label vertical side as a and bottom side as b and the hypotenuse as c. (- 1 point for not labeling as the instructions).Please answer the following:a. At what rate was the top end of the ladder sliding down when it was 6 feet above the ground

, 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

, and for
