Greetings tutor, I need your assistance with question a,b,c and activity 3. Thank you!

The annual sales earned by Nintendo Co., Ltd, in the fiscal years from April 1, 2004 to April 1, 2010, can be approximated by R(t)=-14.54t'+ 38t' + 380+510 billion yen (*) per year (0st$6 ) where t is the time in years and t = 0 corresponds to April 1, 2004. A) Estimate Nintendo's total revenue for the period April 1, 2006 to April 1, 2010. Include an appropriate integral whose value gives the total revenue. Use your graphing calculator to compute the integral. Round answer to the nearest billion yen.El) Suppose that from April 2004 on, Nintendo invested the revenue it received in an investment yielding 5% interest compounded continuously. What would be the future value of the investment at the end of the period from April 1. 2006 to April 1, 2010? Include an integral whose value gives this future value and compute the integral using your calculator. Round answer to the nearest billion yen. C) Look up the conversion factor {Google this) for converting from yen to dollars. Then show work using it to convert y0ur answers in parts A and B to the nearest dollar. Be sure to include the conversion factor with your work. Activity #3: Present Value Max was injured and can no longer work. As a result of a lawsuit. he is awarded the present value of the income he would have received over the next 30 years. His income at the time he was injured was $30,000 per year. increasing by $1500 per year. What will be the amount of his award. aSSuming continuous income and a 6% interest rate? Include an integral that must be evaluated to determine this amount and then use your graphing calculator to estimate the integral. Round nal answer to the nearest cent
