Step-by-step explanation:
Where is the number that will be fill X or Y to solve this equation
Answer:
Two triangles are similar if they meet one of the following criteria. : Two pairs of corresponding angles are equal. : Three pairs of corresponding sides are proportional. : Two pairs of corresponding sides are proportional and the corresponding angles between them are equal.
Dos triángulos son similares si cumplen uno de los siguientes criterios. : Dos pares de ángulos correspondientes son iguales. : Tres pares de lados correspondientes son proporcionales. : Dos pares de lados correspondientes son proporcionales y los ángulos correspondientes entre ellos son iguales.
Step-by-step explanation:
Rewrite equation so that it is homogeneous .
![ay'' +by' + cy = 0](https://tex.z-dn.net/?f=ay%27%27%20%2Bby%27%20%2B%20cy%20%3D%200)
Solve characteristic equation:
The solutions to the homogeneous equation are:
![y = k_1 e^{r_1 t} + k_2 e^{r_2 t}](https://tex.z-dn.net/?f=y%20%3D%20k_1%20e%5E%7Br_1%20t%7D%20%2B%20k_2%20e%5E%7Br_2%20t%7D)
Finally you need the constant term in "cy" to equal 'd' to satisfy the particular solution.
