The total number of electric cars that are sold each year has been growing exponentially. In the initial year of major production (year zero), 50,000 electric cars were sold world wide. Four years later, the number of cars sold in a year had increased to 500,000. Find the exponential growth constant k and write down an exponential function A(t) that models the number of electric cars sold in year t of major production. According to this model, how many cars will be sold in year ten? How many years (after the initial year of major production) will pass before the number of electric cars sold in a year reaches 100,000,000?

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
