A bus currently has three passengers, Crew, Marty, and Blakely. Marty's age is 1.5 times Crew's age. Blakely's age is 0.75 times Crew's age. If the sum of the three ages is 104, find the age of each passenger.

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)

Find the zeros of each function. f(x) = x^2 + 5x - 6

Proportions in triangles solve for x
