A child throws a penny upward out of a window and watches it fall to the ground. The function f (t) = –16t^2 + t + 10 represents the penny's distance in feet above the ground t seconds after the penny is thrown.
Approximately how many seconds does it take the penny to hit the ground?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

The weight v of an object on venus varies directly with its weight e on earth. a person weighing 120 lb on earth would weigh 106 lb on venus. how much would a person weighing 150 lb on earth weigh on venus?

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
