The decay of 212 mg of an isotope is given by A(t) = 212e -0.02t, where t is time in years. Find the amount left after 28 years.

What is the multiplicative rate of change of the exponential function shown on the graph?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

If rt is greater than ba, which statement must be true ?
