Question 30 1 pts Use a graphing calculator to estimate the solution set of the equation. Round to the nearest hundredth. 32X=11+1 Q {0.38} D Question 47 1 pts Solve the problem. Coffee is best enjoyed at a temperature of 11?F. A restaurant owner 1wants to discover the temperature T at which he should serve his coffee so that it will have cooled to this ideal temperature in 6 minutes. He discovers that a cup of coffee served at 19?F cools to 181F in one minute when his restaurant is at 68F. If he maintains the restaurant temperature at 68F, at what temperature should he serve the coffee to meet his goal? 19?"F 1?er 1mm 195m D Question 48 1 pts Solve the problem. Suppose the government wants to impose a tax on fossil fuels to reduce carbon emissions. The cost benefit is modeled by In(1 - P) =-0.0039 - 0.0057x, where x represents the dollars of tax per ton of carbon emitted and P represents the percent reduction in emissions of carbon. (P is in decimal form.) Determine P when x =67. Round to three decimal places. O -0.23 O 1.680 -0.315 O 0.32
