You work for a factory making bricks. A coworker accidentally contaminated one of the bricks with lightweight material and it must be removed. Given a pile of 50 bricks and a balance scale, how can you find the one that weighs less? The scale can hold any number of bricks on each side of the scale at one time, and it will tell you if the two sides weigh the same, or which side is lighter if they do not weigh the same. Describe the algorithm to find the contaminated, lightweight brick. How many weighings will you do? Find an algorithm that uses the least number of weighings possible. State and justify your answer as a function of n, the total number of bricks.

    In this exercise you will work with LU factorization of an matrix A. Theory: Any matrix A can be reduced to an echelon form by using only row replacement and row interchanging operations. Row interchanging is almost always necessary for a computer realization because it reduces the round off errors in calculations - this strategy in computer calculation is called partial pivoting, which refers to selecting for a pivot the largest by absolute value entry in a column. The MATLAB...

    1)Now, the issue of the effect of carbon dioxide (carbon) is one that is hotly debated. You will find scientific arguments that indicate things are actually worse than the science-based models predict. And, you will find arguments that indicate the opposite. Some of these may not be well supported by science and thus do not hold up under careful scientific scrutiny. Indeed, there is some thought that even if we were to eliminate most people-induced carbon emissions promptly, Earth would...

    Instructions: Below are both crater images (some of the work is already done for you on the Southern image). At the bottom left you will see scale bars and a set of circles to help you do the actual counting. We have already identified craters that are 8 km across with red dots, so you only need to worry about craters greater than the outlined ones. Do not recount those craters that have already been marked with red dots. To...
