The amount of time (in hours per week) a student utilizes a math-tutoring center roughly follows the normal distribution \(y=0.7979 e^{-(x-5.4)^{2} / 0.5},\) \(4 \leq x \leq 7,\) where \(x\) is the number of hours. (a) Use a graphing utility to graph the function. (b) From the graph in part (a), estimate the average number of hours per week a student uses the tutoring center.
he value \(V\) (in millions of dollars) of a famous painting can be modeled by \(V=10 e^{k t},\) where \(t\) represents the year, with \(t=0\) corresponding to 2000 . In 2008 , the same painting was sold for \(\$ 65\) million. Find the value of \(k,\) and use this value to predict the value of the painting in 2014 .
An exponential growth model has the form ________ and an exponential decay model has the form ________.
(a) solve for \(P\) and (b) solve for \(t\). $$A=P\left(1+\frac{r}{n}\right)^{n t}$$
Solve the logarithmic equation algebraically. Approximate the result to three decimal places. $$\log _{2}(2 x-3)=\log _{2}(x+4)$$
