Applied Calculus......
Under a set of controlled laboratory conditions, the size of the population of a certain bacteria culture at time t (in minutes) is described by the following function. P=f(t)=3t^2+2t+1 Find the rate of population growth at t = 9 min.

Applied Calculus......
Find the slope m of the tangent line to the graph of the function at the given point and determine an equation of the tangent line. f(x)=6x-5x^2 at (-2, -32) I have to use the four step process, but seem to be getting stuck...

Use the method of bisection to find the root of the equation x^5 + 3x − 7 = 0 accurate to two decimal places.

Applied Calculus......
Suppose a snowy-tree cricket chirps 180 times per minute if the temperature is 102 degrees, and chirps 120 times per minute when the temperature is 90 degrees. Construct a mathematical model that will predict the number of chirps per minute at a temperature in degrees Fahrenhe...
