Asmall company manufactures a certain product. the price-production relationship for this product is p = -0.7*d + 300, where p is the unit sales price of the product and d is the annual production (number of units produced). suppose variable costs are $25 per unit produced and fixed costs are $10,287 . find the break even point (minimum number of units that must be produced for a business to become profitable). note: there are 2 roots in the breakeven equation, choose the smallest root.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
