- The figure shows the graphs of the cost and revenue functions for a company that manufactures and sells small radios. Use the information in the figure to solve Exercises 67–72. 35,000 30,000 C(x) = 10,000 + 30x 25,000 20,000 15,000 R(x) = 50x 10,000 5000 100 200 300 400 500 600 700 Radios Produced and Sold 67. How many radios must be produced and sold for the company to break even? 68. More than how many radios must be produced and sold for the company to have a profit? 69. Use the formulas shown in the voice balloons to find R(200) – C(200). Describe what this means for the company. 70. Use the formulas shown in the voice balloons to find R(300) – C(300). Describe what this means for the company. 71. a. Use the formulas shown in the voice balloons to write the company's profit function, P, from producing and selling x radios. b. Find the company's profit if 10,000 radios are produced and sold. 72. a. Use the formulas shown in the voice balloons to write the company's profit function,…arrow_forwardThe tuition in the school year 2012–2013 at a certain university was $15,000. For the school year 2017–2018, the tuition was $17,850. Find an exponential growth function for tuition T (in dollars) at this university t years after the 2012–2013 school year. (Round your values to four decimal places.) T = Assuming it increases at the same annual rate, use the function to predict the tuition (in dollars) in the 2021–2022 school year.

- Math 116 Section 6.1 Powers of e What does the graph of e* look like? e3.1 ≈ e-0.5 Exponential models that use e as a base are called continuous growth or decay models. Seen in finance, computer science, biological science, physics and fluid dynamics. Formula A(t) = aert a = initial value r = continuous growth rate per unit of time t = elapsed time r> 0 growth r< 0 decay For Business applications use A (t) = Pert Example 7: Continuous growth A person invested $1000 in an account earning a nominal 10% per year compounded continuously. How much was in the account at the end of one year? Example 8: Continuous Decay Radon-222 is a radioactive isotope that decays at a continuous rate of 17.3% per day.

Prehistoric cave paintings were discovered in a cave in France. The paint contained 15% of the original carbon-14. Estimate the age of the paintings. 20. Skeletons were found at a construction site in San Francisco in 1989. The skeletons contained 88% of the expected amount of carbon-14 found in a living person. In 1989, how old were the skeletons?arrow_forward
