in this video I'd like to go over how to use the e button on the calculator to show that I'm going to use this example the population of a rural city follows the exponential growth model P of T is equal to 30 100 e to the zero point zero four two T where T is the number of years after 1994 I first want to talk about the variable T if T is the number of years after 1994 that means that T equals zero would represent the Year 1994 and then T equals one would represent one year after 1994 T equals two would represent two years after 1994 and so on let's say we want to use the model to predict the population in the year 2020 the first thing we need to find is the value for T 2020 - 1994 is 26 so we're looking for the population 26 years after 1994 so our T value is 26 and we plug that into our model now we can use the calculator we can use the calculator by plugging it in in pieces or plugging it all together and I'll show both ways and we'll start by plugging it in in pieces so to do that we can just do 0.04 2 times 26 and now we need to use the e button in the calculator to get to the e button on the calculator we're going to need to use the Ln button press 2nd Ln which gives us e to the exponent so the exponent is already programmed for most calculators so we don't need to type it again and now we're just going to put in our exponent of one point zero nine two and parenthesis and then enter and this gives us two point nine eight zero two two eight five seven three and then the last step would be to multiply which rounding that to the nearest integer since we're talking about a population would be nine thousand two hundred and thirty nine people if we want to plug it in all at once I'll start with thirty-one hundred times and then second e zero point zero four two times twenty six and parenthesis and that gets us to the same answer
