13A polar explorer is planning an expedition. He investigates three possible routes. (a) If he travels on route A, which is 800 km long, he expects to cover x km per day. Route B, which is the same distance as route A, has more difficult ice conditions and he would only expect to cover (x-5) km per day. Route C, which is 100 km longer than route A, has easier conditions and he would expect to cover (x+5) km per day. Write down an expression, in terms of x, for the number of days that he expects to take on route A,

For a certain company, the cost for producing a items is 40x + 300 and the revenue for selling x items is 80x – 0.5x². The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit! Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.) Part b: Find two values of that will create a profit of $50. The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x + 1; x – 1). The order of the list does not matter. To enter va , type sqrt(a).
2.) The Aitken Skateboard Company makes custom skateboards. They have figured out that their profit can be modeled by the equation: P = -2b? + 14b – 20 where b is the number of skateboards produced (in thousands >so for example 1,000 skateboards would be plugged in as 1) and P is the company's profit (in hundreds of thousands of dollars). • How many skateboards should they produce to maximize their profit? What is their max profit? Explain how you found that value. • How many skateboards should they produce to make zero profit? (Known as the break even point). Explain how you found that value. What is the companies ' profit if they produce 3,000 skateboards? 4,500 skateboards? Explain how you found those values.
A rancher has 260 meters of fence with which to enclose three sides of a rectangular meadow (the fourth side is a cliff wall and will not require fencing). Find the dimensions of the meadow with the largest possible area. (For the purpose of this problem, the width will be the smaller dimension (needing two sides); the length with be the longer dimension (needing one side).) length = meters width= meters What is the largest area possible for this meadow? area = meters-squared Enter your answers as numbers. If necessary, round to the nearest hundredths.
