2. A bacteria colony starts with 3 bacteria at the beginning and doubles every hour. How would
you write an explicit equation to model this situation?
A f(x) = 2-3*
B. f(x) = 3x + 2
c. f(x) = 2x + 3
D. f(x) = 3.2*

Which triangles area would be calculated using the trigonometric area formula

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
