AP CALCULUS PLZ HEL The area under a curve y = f(x) over the interval [0, 4] with n equal subdivisions can be expressed as Limit of Sigma-summation Underscript k = 1 Overscript n EndScripts StartFraction 4 Over (m Subscript k Baseline) squared EndFraction times StartFraction 4 Over n EndFraction as n approaches infinity, where mk is the midpoint of the kth subdivision. If the definite integral integral from 0 to 4 of f (x) d x represents this limit, then f(x) =
4 Over x
4 Over x squared
16 Over x
16 Over x squared

Apool measures 12.3 feet by 16.6 feet. if the longer wall of the pool has a diagonal of 17.8 feet, what is the volume of the pool? (round to nearest tenth)

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
