Emerson is studying the change in the amount of money in two accounts, A and B, over time. The amount f(x), in dollars, in account A after x years is represented by the function below: f(x) = 1,264(1.09)x Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points) Part B: The table below shows the amount g(r), in dollars, of money in account B after r years. r (number of years) 1 2 3 4 g(r) (amount in dollars) 1,375 1,512.50 1,663.75 1,830.13 Which account recorded a greater percentage change in amount of money over the previous year?

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2
