Part a: explain why the x-coordinates of the points where the graphs of the equations y=4^-x and y= 8^-x-1 intersect are the solutions of the equation 4^-x = 8^-x-1. part b: make tables to find the solution to 4^-x= 8^-x-1. take the integer values of x between -3 and 3. part c: how can you solve the equation 4^-x = 8^-x-1 graphically?

How to do this , and can some one explain

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
