The cost, C(x), of producing x Totally Cool Coolers is modeled by the function C(x)=0.005x^2−0.5x+23 How many coolers need to be produced and sold in order to minimize the cost? (Round to the nearest whole number.) The cost is at a minimum after _ coolers are produced and sold. What is the cost? (Round answer to the nearest cent.) The minimum cost is $ _ .

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
