The following exercise gives you experience in using the cost and revenue functions to find the break-even point. (See Example 5.) The Computer Shop sells computers. The shop has fixed costs of $900 per week. Its average cost per computer is $549 each, and the average selling price is $849 each. (a) Write the linear cost function $C(x)$. $C(x) =$ (b) Write the linear revenue function $R(x)$. $R(x) =$ (c) Find the cost of selling 31 computers per week. $ (d) Find the revenue from selling 31 computers. $ (e) Find the break-even point. computers Show My Work (Required) What steps or reasoning did you use?

The Taylor series formula of a function f centered at $a$ can be written as: $$f(x) = \sum_{n=0}^{\infty} a_n (x - a)^n \quad \text{where} \quad a_n = \frac{f^{(n)}(a)}{n!}$$ Find the Taylor series for $f(x) = 7 \cos(x)$ centered at $a = 11\pi$ and use it to find $a_4$.

Consider the following function, $f(x) = x^{\frac{1}{3}}$, $a = 1$, $n = 3$, $0.9 \le x \le 1.1$ (a) Approximate $f(x)$ by a Taylor polynomial with degree $n$ at the number $a$. (b) Use Taylor's Inequality to estimate the accuracy of the approximation $f(x) \approx T_n(x)$ when $x$ lies in the given interval. (Round your answer to six decimal places.)
