Ramon is standing on a balcony 84 feet above the ground and throws a penny straight down with an inital velocity of 10 feet per second. The path of the penny is represented by the equation h(t) = 16t2 + 10t + 84. In how many seconds will the penny reach the ground? A. 2 seconds B. 6 seconds C. 3 seconds D. 8 seconds

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
