- The number N of beavers in a given area after x years can be approximated by N=5.5100.23x,0x10. Use the model to approximate how many years it will take for the beaver population to reach 78.arrow_forwardThe rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.arrow_forwardThe maximum weight M that can be supported by a beam is jointly proportional to its width w and the square of its height h and inversely proportional to its length L. a Write an equation that expresses this proportionality. b Determine the constant of proportionality if a beam 4 in. wide, 6 in. high, and 12 ft long can support a weight of 4800 lb. c If a 10-ft beam made of the same material is 3 in. wide and 10 in. high, what is the maximum weight it can support?arrow_forward
- Gas mileage actually varies slightly with the driving speed of a car (as well as with highway vs. city driving). Suppose your car averages 29 miles per gallon on the highway if your average speed is 48 miles per hour, and it averages 26 miles per gallon on the highway if your average speed is 65 miles per hour. Answer parts (a) and (b) below. a. What is the driving time for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the driving time at 65 miles per hour? The driving time at 48 miles per hour is hours. (Type an integer or decimal rounded to two decimal places as needed.) The driving time is at 65 miles per hour is (Round to two decimal places as needed.) b. Assume a gasoline price of $4.43 per gallon. What is the gasoline cost for a 2300-mile trip if you drive at an average speed of 48 miles per hour? What is the gasoline cost at 65 miles per hour? The gasoline cost at 48 miles per hour is $ (Round to two decimal places as needed.) hours. The…arrow_forward1. Let D = the sales of DVDs in billions of dollars, S = the total sales of streaming videos in billions of dollars, and t = the number of years after 2009. D=−0.92⋅t+8.75D=-0.92⋅t+8.75 S=2.3+0.8⋅tS=2.3+0.8⋅t a. In what year should the DVD sales drop below 1.7 billion? show work b. In what year do the models predict streaming video sales to exceed DVD sales? show workarrow_forwardPlease help. Thank you .arrow_forward
- 2. The number of bacteria in a Petri dish increases by 18% every hour. If there were initially 200 bacteria placed in the Petri dish, which function can be used to determine the number of bacteria in the Petri dish in y = 200 (0.82)* exactly x hours? y = 200 (1.18)" y = 200 (1.82)* 200 (0.18)"arrow_forwardHelp. Also include how many minutes it would take to have 9 million bacterium.arrow_forward3. From 1970 to 1990, Sri Lanka's population grew by approximately 2.2 million persons every five years. The population in 1970 was 12.2 million people.What is the best formula for P, Sri Lanka's population (in millions) in terms of t, the number of years after 1970? O a. P= 12.25t Ở b:P= 12.2 + 2.2 t O c. P 12.2 + 11.0 t O d. P= 12.2 + 0.44 t O e. P = 12.2 x 2.2 (s)arrow_forward

Population Demographics The number of millionsof individuals in the U.S. civilian noninstitutional population 16 years and older who are White, non-Hispanic can be modeled by y = 0.293x + 157.8454,and the remainder of the population can be modeledby 1.73x + 54.094, where x is the number of yearsafter 2000. If the growth continues according tothese models, in what year will the populations beequal?arrow_forwardASAParrow_forward
