dos empresas de telefonía tienen los siguientes tarifas la empresas MiFon cobra una tarifa fija al mes $300 por servicio de telefonía. la empresa Telefon cobra un pago inicial de$1000 y mensual una cuesta de 250,¿cual serán los pagos que se habrán de hacer a lo 1,2,3,4,5,6,7,8,9 y 10 meses? realiza la representación gráfica, tabular y algebraica de ambas empresas. recuerda que la expresión algebraica de una variación directa y=kx y de una variación lineal es y p=kx± b. la necesito para mañana por favor ​

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

the answer is 21%.

answer: 0.26
