(a) Explanation Given Information: The provided revenue function is, R ( t ) = 350 ( 39 t + 68 ) e − 0.3 t . Formula used: Steps to solve optimization problems: Step 1: Identify the unknowns with the aid of diagram. Step 2: Identify the objective function, the quantity to maximize or minimize. Step 3: Identify the constraint, the equations relating variables or inequalities expressing limitations on the value of the variables. Step 4: State the optimization problem Step 5: Eliminate the extra variables, solve the constraint for one unknown and substitute in the objective function. Step 6: Find the absolute maximum or absolute minimum of the objective function. Calculation: Consider the provided revenue function, R ( t ) = 350 ( 39 t + 68 ) e − 0.3 t Now, differentiate the objective function or the revenue function with respect to t as, R ′ ( t ) = 350 ( 39 ) e − 0.3 t − 0.3 ( 350 ) ( 39 t + 68 ) e − 0.3 t = 350 ( 39 − 11.7 t − 20.4 ) e − 0.3 t = 350 ( 18.6 − 11.7 t ) e − 0.3 t To obtain stationary points, set R ′ ( t ) = 0 as, 350 ( 18.6 − 11.7 t ) e − 0 (b) To determine To calculate: The revenue to the nearest $ 1 million at the time to the nearest when the revenue was projected to peak if the provided revenue function is R ( t ) = 350 ( 39 t + 68 ) e − 0.3 t .

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

The U.S. Department of Health and Human Services provides a summary of the number and rate of abortions for the period 1990–2006. Based on these data, the United States abortion rate (number of abortions per 1000 women) can be estimated by the linear function R(x) = −0.58x + 23.9 where x is the year since 1990 and R(x) is the abortion rate. (a) Based on this function, is the rate increasing or decreasing? The slope is , so the rate is . (b) Find the estimated abortion rate for 2007 and for 2017. 2007 abortions per 1000 women 2017 abortions per 1000 women (c) Estimate the year when the abortion rate will be 10. (Round your answer to the nearest year.)

2) The Nikkei 225 index is a stock market index for the Tokyo Stock Exchange. The Nikkei 225 index for the period 1990-2010 can be modeled by V (t) = 23,500e-0.0381t where t is the number of years after 1990. Determine how many years after 1990 the Nikkei 225 index reached $20,000.
