- 3. Once an antibiotic is introduced to bacteria, the number of bacteria decreases exponentially. For example, beginning with 1 million bacteria, the amount present t days from the time streptomycin is introduced is given by the function A(t) = 1,000,000(2)-t/10. Rounding to the nearest thousand, determine how many bacteria are present after 1 week.arrow_forwardUse the Jesaki Inc Information Below to Solve Questions 1- Below 1) Jesaki Inc estimates that it will sell N(x) units of product after spending $x thousand on advertising, as given by N(x) = -0.45 x^4 + 46 x^3 1,079 x x^2+ 161,973. What is the point of diminishing returns? Round to the nearest dollar. 2) The number x of bicycle helmets Jesaki Inc is willing to sell per week at a price of $p is given by x = a/p + b-c, where a = 80, b = 26, and c = 414. Find the instantaneous rate of change of the supply with respect to price when the price is $79. Round to the nearest hundredth (2 decimal places). 3) Jesaki Inc sponsered a blood drive following mathematical model relating systolic blood pressure and age: P(x) = a + bln(x+1), where P(x) is pressure, measured in millimeters of mercury, and x is age in years. By examining Guilford County hospital records, they estimate the values for Guilford County to be a = 43 and b = 27. Using this model, estimate the rate of change of pressure with…arrow_forward11.

Write a function representing the growth of Company B. b. How many stores will Company B have after 4 years assuming the same growth rate? Show your work.arrow_forward5. The average time required to complete an accounting test has been determined to be 59 minutes. Assuming that times required to take tests are exponentially distributed, how many students from a class of 54 should be able to complete the test in between 48 and 58 minutes? Draw the graph for this information.arrow_forward

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_forward(1) Confirm that the data in Table 1.2 for the temperatures 25 °C and 45 °C can also be approximated by constant relative changes. Then find the exponentials that match the data.arrow_forward

The table provided gives data on indexes of output per hour (X) and real compensation per hour (Y) for the business and nonfarm business sectors of the U.S. economy for 1960–2005. The base year of the indexes is 1992 = 100 and the indexes are seasonally adjusted. a. Plot Y against X for the two sectors separately. b. What is the economic theory behind the relationship between the two variables? Does the scattergram support the theory? c. Estimate the OLS regression of Y on X. Note: on the table ( 1. Output refers to real gross domestic product in the sector. 2. Wages and salaries of employees plus employers’ contributions for social insurance and private benefit plans. 3. Hourly compensation divided by the consumer price index for all urban consumers for recent quarters.) Thank you!arrow_forward
