To determine The principal using the formula I = P R T if I = $ 838.50 , T = 1 1 2 years and R = 21 1 2 % . Explanation Procedure used: To evaluate a formula: 1. Write the formula. 2. Rewrite the formula, substituting known values for variables of the formula. 3. Solve the equation from Step 2 for the missing variable. 4. Interpret the solution within the context of the formula. Calculation: The simple interest formula is given by I = P R T . The rate can be expressed as a decimal as follows. 21 1 2 % = 42 + 1 2 % = 43 2 % = 21.5 % = 0.215 Substitute I = $ 838.50 , T = 1 1 2 years and R = 0.215 in the formula I = P R T to obtain principal as follows. 838.50 = ( P ) ( 0.215 ) ( 3 2 ) 838

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.

4. Now we'll look at a nonhomogeneous example. The general form for these is y' + p(x)y = f(x). For this problem, we will find solutions of the equation +2xy= xe (a) Identify p(x) and f(x) in the equation above. p(x) = f(x) = (b) The complementary equation is y' + p(x)y = 0. Write the complementary equation. (c) Find a solution for the complementary equation. We'll call this solution y₁. (You only need one particular solution, so you can let k = 0 here.) Y1 = (d) Check that y₁ satisfies the complementary equation, in other words, that y₁+ p(x)y₁ = 0.
