Geometry A rectangular playing field with a perimeter of 100 meters is to have an area of at least 500 square meters. Within what bounds must the length of the rectangle lie?
A Rational Function with a Slant Asymptote In Exercises \(49-62,\) (a) state the domain of the function, (b) identify all intercepts, (c) find any vertical or slant asymptotes, and (d) plot additional solution points as needed to sketch the graph of the rational function. $$f(x)=\frac{2 x^{2}-5 x+5}{x-2}$$
Finding the Domain of an Expression In Exercises \(61-66\) , find the domain of the expression. Use a graphing utility to verify your result. $$\sqrt{\frac{x}{x^{2}-2 x-35}}$$
Learning Curve The management at a plastics factory has found that the maximum number of units a worker can produce in a day is \(30 .\) The learning curve for the number \(N\) of units produced per day after a new employee has worked t days is modeled by \(N=30\left(1-e^{k t}\right) .\) After 20 days on the job, a new employee produces 19 units. (a) Find the learning curve for this employee (first, find the value of \(k )\) (b) How many days should pass before this employee is producing 25 units per day?
A bulk food storage bin with dimensions 2 feet by 3 feet by 4 feet needs to be increased in size to hold five times as much food as the current bin. (Assume each dimension is increased by the same amount.) (a) Write a function that represents the volume \(V\) of the new bin. (b) Find the dimensions of the new bin.
