Explanation Procedure used: “ Problem-solving Steps 1. UNDERSTAND the problem. During this step, become comfortable with the problem. Some ways of doing this are as follows: a). Read and reread the problem b). Construct a drawing. c) Propose a solution and check. Pay careful attention to how you check your proposed solution. This will help when writing an equation to model the problem. d) Choose a variable to represents an unknown. Use this variable to represent any other unknowns. 2. TRANSLATE the problem into an equation. 3. SOLVE the equation. 4. INTERPRET the results: check the proposed solution in the stated problem and state the conclusion.” Calculation: UNDERSTAND: It is given that, the United states uses 116 million more personal computers than China and the both countries are used 506 million. Let x be number of personal computers used by China. Then the number of personal computers used by United states is x + 116 . The resulting statement is, the sum of computers used by each countries is equal to the total computers use by both countries. TRANSLATE: Translate the statement “the sum of computers used by each country are equal to the total computers use by both countries” into an algebraic expression as follows. In words : the sum of personal computers used in each countries is total computers used in both countries ↓ ↓ ↓ Translate: x + ( x + 116 ) = 506 That is, the algebraic expression is x + x + 116 = 506

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

This question builds on an earlier problem. The randomized numbers may have changed, but have your work for the previous problem available to help with this one. A 4-centimeter rod is attached at one end to a point A rotating counterclockwise on a wheel of radius 2 cm. The other end B is free to move back and forth along a horizontal bar that goes through the center of the wheel. At time t=0 the rod is situated as in the diagram at the left below. The wheel rotates counterclockwise at 1.5 rev/sec. At some point, the rod will be tangent to the circle as shown in the third picture. B A B at some instant, the piston will be tangent to the circle (a) Express the x and y coordinates of point A as functions of t: x= 2 cos(3πt) and y= 2 sin(3πt) (b) Write a formula for the slope of the tangent line to the circle at the point A at time t seconds: -cot (3πt) (c) Express the x-coordinate of the right end of the rod at point B as a function of t: 2 cos(3πt) +41/1 (d) Express the slope of the rod…
