Need
part a: explain why the x-coordinates of the points where the graphs of the equations y=4^-x and y=2^x+3 intersect are the solutions of the equation 4^-x=2^x+3.
part b: make tables to find the solution to 4^-x=2^x+3. take the integer values of x between -3 and 3.
part c: how can you solve the equation 4^-x=2^x+3 graphically?

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
