Ryan collects animal figures he has 45 elephants 36 zebras and 18 tigers he will arrange the figures into rows each row will have the same number of figures in all the figures in a row will be the same

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

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)

Are the corresponding angles congruent? explain why or why not.
