An element with a mass of 890 grams decays by 19.7% per minute. To the nearest
tenth of a minute, how long will it be until there are 220 grams of the element
remaining?

The factorization of 8x3 -125 is (2x-5)(jx2 +kx+25)

What is another way to express 36 +32

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)
