8. Write the equation of the line that is perpendicular to the line y= -1/5X + 9 and passes through the point (-2,-2). *

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)

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

Solve the equation for x. 50(4x + 12) = 200
