The function f(x)= kx^3 - 8x^2 -x + 3k + 1 has a zero when x=2. determine the value of k. graph f(x) and determine all the zeros. then rewrite in factored form. i found that k=3 so far, but i'm not sure how to graph it without making a table of values, or how to find the zeros. any ideas?

In the figure below, m∠r is 60°, and m∠t is 120°. what is m∠q? a. 60° b. 30° c. 120° d. 54

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
