- Cesium-137 has a half-life of about 30 years. If we begin with 200 mg of cesium-137, will it take more or less than 230 years until only 1 milligram remains?Find an exponential function with horizontal asymptote y = 2 whose graph contains the points (0, 3) and (1, 5).The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 13% per hour. An initial sample is obtained from this population, and after two hours, the sample has grown to 2633 bacteria. Find the number of bacteria in the initial sample. Round your answer to the nearest integer. Note: This is a continuous exponential growth model.And though the growth rate parameter is 13% per hour, the actual growth is not 13% each hour.

How can I use an exponential model of the form Ae^rt to solve this word problem?Find a possible formula for the exponential function through the points (0,3) and (3,24) graphed below. y=
- A lush forest has 100 foxes and 2 rabbits. The fox population doubles every year and the rabbit population triples every year. The foxes agree not to hunt the rabbits until they are outnumbered by the rabbits. -Let t be the number of years that pass, and come up with two exponential expressions that model the fox population and rabbit population respectively. -The rabbits will equal (and then shortly outnumber) the foxes midway through some year. Find the value of t such that the two populations are equal, accurate to four decimal places, and the populations of each animal at that time to the nearest whole number.A man with $30,000 to invest decides to diversify his investments by placing $15,000 in an account that earns 5.2%compounded continuously and $15,000 in an account that earns 6.4% compounded annually. Use graphical approximation methods to determine how long it will take for his total investment in the two accounts to grow to $45,000. It will take approximately ____ years for his total investment in the two accounts to grow to $45,000. (Type an integer or decimal rounded to one decimal place as needed.)A certain quantity has an initial value of 8.2 and grows at a rate of 8.5% per year.

In your vast biological knowledge, you note that the doubling time (i.e., the number of days it takes the cumulative number of cases to double in size) of the zombie virus is approx- imately 3.5 days. Suppose we are interested in the spread of the virus in our class (if we were all contained in a very large lecture hall, of course), where the instructors are initially infected (there are 10 instructors, for reference). (a) Use the exponential function C(t) = C0ert to determine r, the growth rate of the zombie virus. Your answer should be given in the most exact representation (i.e., not a decimal). (b) Our coordinator, Dr. James, determines that the zombie virus will be classified as an outbreak in our classroom if 25% of the class becomes infected (for reference, there are 2500 students and instructors combined in CALC1000). If the virus is…Find the equation of the guadratic function with vertex (-5,3) and which passes through the point (2,9).
