7. Use your graph to estimate how the scale factor changes between a box with volume of 1 cubic foot and one with volume of 5 cubic feet.

28. Alcohol Concentration The following graph shows the ap- proximate concentration of alcohol in a person's bloodstream t hr after drinking 2 oz of alcohol. Estimate the total amount of alcohol in the bloodstream by estimating the area under the curve. Use rectangles with widths of 1 hr. Alcohol concentration/hour 4 3 2 12 3 Hours 5 6 7 8

t نها N my -1 -2 -3 3 4 5 2 The graph above shows the base of an object. Compute the exact value of the volume of the object, given that cross sections (perpendicular to the base) are squares.

The radius of a ball bearing is measured by a micrometer to be 1.2 mm with a margin of error of 0.05 mm. Given this error, estimate the maximum error in the volume ofthe ball bearing.What is the relative error? What is the percent error?

1. Find a set of dimensions for a rectangular prism with volume 60 cubic units. Calculate the surface area e of your prism. You can organize your information using this chart as a guide: Surface y Volume Area 2. A lithium ion battery contains a rectangular prism made of lithium. The energy in the battery is proportional to the surface area of this prism. Assume the lithium has a fixed volume of 60 cubic millimeters. Find the dimensions of a rectangular prism with this volume that maximizes its surface area. What is its surface area? ***Click "Next" to continue with lesson 5.11*** L Get Help with Technology Next « Previous

find the diameter of the cone with a volume of 489.84 cubic meters

3. A snowball is rolling down a hill, getting bigger as it goes. Assume the snowball remains a perfect sphere. If the volume of the snowball is increasing at a constant rate of 10 cubic inches per second, how fast is the radius of the snowball changing at the instant the radius is 4 inches? Include units. Round to the nearest hundredth. Will the rate of change of the radius be faster, slower, or the same when the radius is 8 inches?
