\f\f3. Solve 4* = 36, accurate to three decimal places. (3 marks) You may use logs, guess and test, or Desmos. Clearly indicate which you used.\f6. An investment can be modelled by the equation A = 2500(1.06 )', where A represents the final amount of the investment and t represents the time in years. How many years would it take to have a final amount equal to $10 000? Round your answer to the nearest tenth of a year. (4 marks)T. The surface area of a cylinder is given by the formula 3A = 2;: r9+2rrrh. where r represents the radius and h represents the height. Solve the formula for h and then use it to complete the following table accurate to two decimal places. [marks] 6 marks Just do Cylinder A and El [save some time) m Surface Area. 8A {cn mm 435 Radius. r /-/, determine the height if the radius is to be 1.2 m. 16. Two investors, Brent and Lincoln, invest different amounts of money at the same time for an 8-year period. Brent invests $10 000 at 6% per year and his final amount is given by the formula A = 10000(1.06 )'. Lincoln is shrewder, and was able to invest only $8000 and end up with the same amount at the end. His final amount can be modelled using the equation A = 8000(1+/ ) . Determine the value of / for Lincoln and the yearly interest rate his money earned to allow this to happen
