a) Write an exponential decay function that represents the amount of the substance remaining, N(t), as a function of time in years (t). b) Use your function to determine the amount of the substance remaining after 20 years.
Problem 4 : A virus spreads through a network of computers such that each minute, 25% more computers are infected. If the virus began at only one computer, find the model for this situation and find the number of computers affected after 40 minutes.
Problem 4 : In 2010 an item cost $9.00. The price increase by 1.5% each year. A. Write an exponential growth function to represent this situation. B. How much will it cost in 2030? Round your answer to the nearest cent. Solution: A. y = 9.00(1 + 1.5%) t. t = time in years. y = 9.00(1 + 0.015) t. y = 9.00(1.015) t. B. At 2030, t = 20 years. y ...

Follow the step-by-step procedure below to write an exponential function. Step \ (1\): Analyzing the problem and identifying the variables. At this stage, you should specify what the question is about and what the variables of the problem are. Step \ (2\): Using the variables, write the exponential function in the form of \ (y=ab^x\).
