Find a particular solution to the differential equation using the Method of Undetermined Coefficients. A solution is e Superscript StartFraction t/2 EndFraction Baseline (cosine (5 StartRoot 23 EndRoot StartFraction t Over 2 EndFraction) + sine (5 StartRoot 23 EndRoot StartFraction t/2 EndFraction) + cosine (12t).

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Can someone me out here number 4 plz
