Riley collects rainwater in a large barrel that weighs 15 pounds. When there are 8 gallons of water in the barrel, the total weight is 73.8 pounds. When there is 20 gallons of water in the barrel, the total weight is 162 pounds. Write the equation that models this situation in slope intercept form.

Factor -8x3-2x2-12x-3 by grouping what is the resulting expression?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
