I'm getting the correct answers here can you help me?

The population of Nilam doubles in size every 6 yr. In 1990, its population was 20,000. a) Find an exponential function of the form P(t) = Pon that models Nilam's population after t year b) Find the equivalent exponential model of the form P(t) = Poet c) What is Nilam's yearly percentage growth rate? d) Without using a calculator, find Nilam's population in 2008. e) How fast was Nilam's population changing in 2000? - IF a) Find an exponential function of the form P(t) = Pon that models the situation. The exponential function is P(t) = (Use integers or fractions for any numbers in the expression.)
