A population numbers 15,000 organisms initially and decreases by 4.1 % each year. Suppose P represents population, and t the number of years of growth. An exponential model for the population can be written in the form P - a bt where Preview
A population numbers 14,000 organisms initially and grows by 8.8% each year. Suppose P represents population, and t the number of years of growth. An exponential model for the population can be written in the form P = a.b' where P = If 24500 dollars is invested at an interest rate of 10 percent per year, find the value of the investment at the end of 5 years for the following compounding methods, to the nearest cent. (a) Annual: $...

Write the equation in logarithmic form. Assume that all constants are positive and not equal to 1. 10" = n=log10 Hint Preview 72 log 10 syntax error. [use function notation - use log(10) instead of log10). Points possible: 1 This is attempt 1 of 1. License The fox population in a certain region has an annual growth rate of 5 percent per year. It is estimated that the population in the year 2000 was 10600. (a) Find a function that...
Suppose the population grows (in thousands) according to the following relationship, P=125e0.012t , where t is the number of years. Using logarithms, find the number of years t, it would take for the population P, to double, that is equal 250. Also comment on the meaning of the exponent
A city has a population of 290,000 people. Suppose that each year the population grows by 7.5%. What will the population be after 14 years? Use the calculator provided and round your answer to the nearest whole number. people x 6 ?
&7 4. A population P grows at a constant rate of a organisms per unit time, and the death rate is proportional to the population size with the proportionality constant k. A. Assume the initial population P(0) Po. Write a differential equation that models the size of the population P(t) at ay time t. B. Write the equation from part A in standard form, and solve. (The answe terms Po, a, k and a constant C.) wer must contain the...
ASAP please 3. Suppose the population grows (in thousands) according to the following relationship, P=125e9.012, where t is the number of years. Using logarithms, find the number of years t, it would take for the population P, to double, that is equal 250. Also comment on the meaning of the exponent.
