Determine the balance for $2500 at a rate of 3% for 20 years
Compounded both monthly and continuously.
Find the domain, x-intercept, vertical or horizontal asymptotes of the logarithmic function and
sketch its graph.
f(x) = ln(3-x)
Use the properties of logarithms to expand the expression as a sum, difference, and /or constant
multiple of logarithms.
Ln 4x3(x2 -4)
Condense the expression to the logarithm of a single quantity.
½ [log (x + 1) + 2 log (x – 1)] + 6 log x
The number of endangered animal species in the US from 1990 to 2002 can be modeled by
Y = -119 + 164ln t , 10 ≤ t ≤ 22
Where t represent the year, with t = 10 corresponding to 1990. During which year did the number of
endangered animal species reach 357?
How long will it take an initial investment of $600 at a rate of 4.5% to double if
compounded quarterly?
The number y of hits a new search engine website receives each month can be modeled by y = 4080 ekt
where t represents the number of months the website has been operating. In the websites’s third month, there were 10,000 hits. Find the value of k, and use this result to predict the number of hits the website
will receive after 24 months.
The number N of bacteria in a culture is modeled by
N = 100ekt
Where t is the time in hours. If N = 300 when t = 5, estimate the time required for the population to
double in size.
