- Table 2 shows a recent graduate’s credit card balance each month after graduation. a. Use exponential regression to fit a model to these data. b. If spending continues at this rate, what will the graduate’s credit card debt be one year after graduating?arrow_forwardCan the average rate of change of a function be constant?arrow_forwardTable 6 shows the population, in thousands, of harbor seals in the Wadden Sea over the years 1997 to 2012. a. Let x represent time in years starting with x=0 for the year 1997. Let y represent the number of seals in thousands. Use logistic regression to fit a model to these data. b. Use the model to predict the seal population for the year 2020. c. To the nearest whole number, what is the limiting value of this model?arrow_forward
- The population in an African preserve is estimated to at 600 lions. The growth rate based on the last two years is about 3% per year. If t represents time in years after this year, which functions best models this situation? = 600(1.03)* а. b. y = 600 + 1.03t c. Y = 600(0.03)' X d. y = 600 + 0.03t y = 600(1.03)*-1 е.arrow_forwardA=A0e^kt 2006 population (millions) Projected 2029 population (millions) Projected growth rate K 46.5 42.7arrow_forwardf(x) = Initial Value Type of Change Rate of Changearrow_forward
- Data about the sound levels from a new speaker are collected at a manufacturing facility and are used to calculate the model ŷ = 62.4(0.915)x, where x represents the distance from the speaker in meters and ŷ represents the predicted sound level in decibels. Interpret the percent rate of change of the model in the context of the problem. For every increase in one meter from the speaker, the sound level is predicted to decrease by about 91.5%. For every increase in one meter from the speaker, the sound level is predicted to decrease by about 8.5%. For every increase in one meter from the speaker, the sound level is predicted to increase by about 91.5%. For every increase in one meter from the speaker, the sound level is predicted to increase by about 8.5%.arrow_forwardNumber 9arrow_forwardSuppose the flow rate (in cubic feet per second, cfs) of a river in the first 11 hours after the beginning of a severe thunderstorm can be modeled as f(h) -0.875h3 12.05h2 - 7.95h 122.03 cfs where h is the number of hours after the storm began 0 andh = 11?
