Hey everybody!!

This is the Developing Expert Voices project of m@rk, -zeph, and me, benofschool...

It took a while to finish but finally here it is!!!

Hello and welcome to our DEV! Below are our questions in text followed by our video presentations. Enjoy!

"The Barry Bonds Question"

Question is in the video.

"The Maximum Triangle"

A circle of radius 5 has a triangle drawn from it's diameter to a point of the circle where the far right of the circle lies on (5,0). For what value of x will the enclosed triangle have the largest area?

"Finding the Lost K"

On the interval 1 is less than or equal to x is less than or equal to 2, for what value of K will the area enclosed between the graphs of f(x) = -(1/x)+k and g(x) = sqr(x) will equal the area enclosed by f(x) and the x axis.

"The Increasing Circle"

A circle with a starting radius of 5cm grows at one point by the radius extending at a rate of 1cm/min. This expanding radius goes around the circle at a rate of 1 revolution per minute. Now this object also has depth. Which at 1 minute is 1m. Since matter cannot be created of destroyed the depth must shrink as the radius expands. What rate does the depth have to shrink at?

"The Triple Graph"

What is the volume of the solid created by rotating the rea enclosed by f(x) = x^3-1, g(x) = e^x and h(x) = -(1/x)+2 and the coordinate axis in quadrant 1 around the x axis?

"The Beast"

Solve the following differential equation in the video.

"The Reflection"

Thanks for watching! I hope you enjoy!
