I need help with this questions please. I need all answers correct please. 1. Suppose that the population of a certain country grows at an annual rate of 5.5%. If the current population is 2 million, what will be the population in 10 years? (Round your answer to the nearest 100 thousand people.) people 2.When first observed, an oil spill covers 4 square miles. Measurements show that the area is tripling every 6 hrs. Find an exponential model for the area A (in mi2) of the oil spill as a function of time t (in hr) from the beginning of the spill. 3.An internet analytics company measured the number of people watching a video posted on a social media platform. The company found 125 people had watched the video and that the number of people who had watched it was increasing by 30% every 3 hours. (a)Write an exponential function for the number of people A who had watched the video n hours after the initial observation. A = (b)A video is said to go "viral" if the number of people who have watched the video exceeds 5 million within 5 days (120 hours). Would this video be considered to have gone viral? Yes No 4.Nitrogen dioxide, NO2, is an air pollutant resulting from burning fossil fuels in cars and power plants. The following table shows the decrease in the national average of the concentration in parts per billion (ppb) of NO2 for selected years. Year 2014 2015 2016 2017 2018 NO2 (ppb) 40.8107 39.7886 38.7972 37.8209 36.8752 Use exponential regression to find an exponential decay function for the concentration, C, of NO2 t years after 2014. Round constants to the nearest ten-thousandth. C = Use the model to predict the concentration of NO2 (in ppb) in 2020. Round to the nearest whole number. ppb 5. The pressure in pounds per square inch was measured at various altitudes of h, in kilometers (km), above Earth's surface. The results are shown in the following table. Altitude (km) 0 10 20 30 40 50 60 70 80 Pressure (lb/in2) 14.7 11.91 9.315 7.64 6.129 4.637 3.676 3.193 2.358 Use exponential regression to find an exponential function for the pressure, P, at an altitude of h km. Round constants to the nearest thousandth. P = Use the model to predict the atmospheric pressure (in lb/in2) at an altitude of 12 km. Round to the nearest tenth. lb/in2
