When visiting Baltimore, MD, you
need to rent a taxi to get from your
hotel to the National Aquarium. The
taxi company charges a flat fee of
$3.00 for using the taxi and $0.75
per mile. Write an equation in slope-
intercept form that models this situation.

Y=0.75x+3

15. Use your equation from problem
14 to calculate the cost for using the
taxi for 18 miles.

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
