I need help with these question please. All answers need to be correct please and my homework is due at 11:59ET Tonight!!! 1.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. 2.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 3.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 11 km. Round to the nearest tenth. lb/in2 4.The value of a certain rare silver dollar was $50,000 in 1980. A price history of the silver dollar shows that it has been doubling in value every 20 years. Find an exponential growth model for A, the value of the coin (in dollars) t years after 1980.(See Example 3 in this section.) A = Use your model to estimate the value (in dollars) of the coin in 2035. Round to the nearest thousand dollars. $ 5.A desalinization process is eliminating 20% of the salt from seawater every 10 minutes. There are initially 550 g of salt in 10 liters of water. Find an exponential function for A, the grams of salt in the 10 liters of seawater t minutes after the process has begun. (See Example 5 in this section.) 6.Suppose a cup of coffee contains approximately 90 milligrams of caffeine. Suppose the time it takes a healthy person to metabolize one-half of the consumed caffeine is approximately 5 hrs. Find an exponential function that gives A, the number of milligrams of caffeine in the body t hrs after drinking a cup of coffee. (See Example 6 in this section.)
