Biologists discovered an invasive species of fish in a lake. The function fff models the population size (in thousands of fish) for this species as a function of time (in months) after being discovered. Plot the point on the graph of fff that corresponds to the time when the population reached its maximum size.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
