Answer:

I believe the answer is 0.5 !

Step-by-step explanation:

The formula for power is:

P = work / time

P = 35J / 70s

P = 0.5

Answer:

0.5 Watts.

Step-by-step explanation:

We are asked to find amount of power used, when 35 J of work was performed in 70 seconds.

We will use power formula to solve our given problem.

$P=\frac{E}{t}$ , where,

P = Power in watts,

E = Energy used in Jules,

t = Time in seconds.

Upon substituting our given values in above formula, we will get:

$P=\frac{35}{70}$

$P=\frac{1}{2}$

$P=0.5$

Therefore, 0.5 Watts of power is used to complete the task.

Solve the following recurrence relation: <br> <img src="https://tex.z-dn.net/?f=A_%7Bn%7D%3Da_%7Bn-1%7D%2Bn%3B%20a_%7B1%7D%20%3D

By iteratively substituting, we have

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

$a_{n-1} = a_{n-2} + (n - 1) \implies a_n = a_{n-2} + n + (n - 1)$

$a_{n-2} = a_{n-3} + (n - 2) \implies a_n = a_{n-3} + n + (n - 1) + (n - 2)$

and the pattern continues down to the first term $a_1=0$ ,

$a_n = a_{n - (n - 1)} + n + (n - 1) + (n - 2) + \cdots + (n - (n - 2))$

$\implies a_n = a_1 + \displaystyle \sum_{k=0}^{n-2} (n - k)$

$\implies a_n = \displaystyle n \sum_{k=0}^{n-2} 1 - \sum_{k=0}^{n-2} k$

Recall the formulas

$\displaystyle \sum_{n=1}^N 1 = N$

$\displaystyle \sum_{n=1}^N n = \frac{N(N+1)}2$

It follows that

$a_n = n (n - 2) - \dfrac{(n-2)(n-1)}2$

$\implies a_n = \dfrac12 n^2 + \dfrac12 n - 1$

$\implies \boxed{a_n = \dfrac{(n+2)(n-1)}2}$
