At time , a particle is located at the point ​(8​, 1​, 6​). It travels in a straight line to the point ​(1​, 9​, 2​), has speed 6 at ​(​8, 1​, 6​) and constant acceleration -7i+8j-4k. Find an equation for the position vector r​(t) of the particle at time t.

49xy +34y - 72z. determine the degree of the polynomial

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
