Which statements correctly describe the graph of the function f(x) = x3 – 2x2 – 19x + 20? check all that apply. 1.as the x-values increase, the y-values always increase. 2.as x approaches negative infinity, y approaches negative infinity. 3.the domain of the function is all real numbers. 4.the range of the function is y 20. 5.the graph has a positive y-intercept.

At a point on the ground 50 meters from the foot of a tree, the angle of elevation to the tree is 48°. find the height of the tree to the nearest meter.

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.)
