Suppose we still want to build a cylinder that has a volume of 100 cubic centimeters, but this time we want to make the top and bottom out of a slightly tougher material than the sides. The material for the top and bottom costs $0.02 per square centimeter and the material for the sides costs $0.01 per square centimeter. Find the radius and height that give us the cheapest cylinder.

Which representation has a constant of variation of -2.5

Math each whole number with a rational,exponential expression

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
