In order join a tennis class , you pay a $200 annual fee, then $10 for each class you go to . What is the average cost per class if you go to 10 classes

In manufacturing a medical equipment, a firm incurs costs of two types. Fixed annual costs of $ 155,000 are incurred regardless of the number of units produced. In addition, each unit produced costs the firm $5. If C equals total annual cost in dollars and x equals the number of units produced during a year;

a) Develop the function C = f(x) which expresses annual cost.

b) Calculate f(280,000)? What does f(280,000) represent?

c) State the restricted domain and restricted range of the function if maximum production

capacity is 850,000 units per year

use long division to determine the quotient and remainder when f(x) = 4x³+6x²-2x+5 is divided by (2x-1)

use long division to find the quotient and the remainder when the function f(x) = x³+3x²-4 is divided by (x-1).hence factorize the function completely

Let a_1,a_2,a_3,a_4,a_5 be an arithmetic progression with common difference d such that cos d=sqrt{0,2}.Find cos^2a_3 given that tg a_1tg a_2+tg a_2tg a_3+tg a_3tg a_4+tg a_4tg a_5 = 16.

John and juana went on a 120 mile canoe trip with their class. On the first day they traveled 30 miles. What percent of the total distance did they canoe?

Linda Jones 250 miles using 9 gallons of gas at this rate how many gallons of gas will she need to drive 275 miles

Type your answers into a text box. Please number your answers. I am looking for your current understanding of the material. Answer each question, even if it is a best guess.

1. Write an equation for a polynomial with all the following features: (write 1 polynomial with all these features combined)

a. The degree is 5

b. the polynomial has 4 terms.

c. the graph of the polynomial crosses the vertical axis at y=12.

(You may want to use equation editor to help write this equation).

Lines can be used to approximate a wide variety of functions; often a function can be described using many lines.

If a stock price goes from $10 to $12 from January 1st to January 31, from $12 to $9 from February 1st to February 28th, and from $9 to $15 from March 1st to March 31th is the price change from $10 to $15 a straight line?

It is clear that in each of the three time intervals mentioned there was a complex daily variation of prices as in an electrocardiogram. But what would be a simplified solution for a first naive view of the situation? Would a simple function hold up? What is the simplest function to represent this situation? Does your naïve initial and simplified model allow you to predict the behavior of the stock in the next month?

How can I use three “pieces” of lines to describe the price movements from the beginning of January to the end of March? Show the graph for the price movement.

Graph the function using a ​[​-5,5,-​5,5] window and use the graph to estimate the domain and range.
