What is the value of p ?

An arc subtends a central angle measuring 7pi/4 radians what fraction of the circumference is this arc?

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.

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)
