A ball is thrown upward from a height of 14.4 m at an initial speed of 31 m/sec. Acceleration resulting from gravity is - 9.8m/sec . Neglecting air resistance, solve for the velocity v(t) and the height h(t) of the ball t seconds after is is thrown. Velocity v(t) = meters/second Height h(t) = meters9 A company's marginal cost function is 7 where x is the number of units. :1: Find the total cost of the first 49 units (of increasing production from x=0 to x=49) Total cost: $ 2,058 X
