Stacy has 3 collector’s cards. She receives 2 more cards each week that she volunteers
at the student center.

Let x = the number of weeks.
Let y = the number of collector’s cards.

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 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)

On a cm grid, point p has coordinates (3,-1) and point q has coordinates (-5,6) calculate the shortest distance between p and q give your answer to 1 decimal place
