If 7m-3=53, what is the value of 11m+2
Anarel [89]
If 7m-3=53, them 7m=53+3
7m = 56, so m = 8.

Plug this into the other equation, 11m+2.
11(8) + 2 = 88 + 2 = 90

Find the general solution of the given differential equation.y^(4)+18y"+81y=0
kotykmax [81]

Answer:

The general solution of the given differential equation

y =  ( c_{1} + c_{2} x ) cos3 x + (  c_{3} +c_{4} x) sin3 x

Step-by-step explanation:

Step(I):-

Given differential equation

                                   y⁴+18y"+81y=0

                         ⇒    (D⁴+18D²+81)y =0

The auxiliary equation

                               m^4+18m^2+81 =0

                              (m^2)^{2} + 2 (9) m^{2} +(9)^2 = 0

        we will use formula  ( a + b)² = a² + 2 a b + b²    

                  ⇒    ( m² + 9 ) ² = 0

                   ⇒    ( m² + 9 ) ( m² + 9 ) = 0

                      m^{2} =-9\\m= - 3i and m=3i

            m² + 9 = 0      

      m² = -9\\m= -3i and m=3i

The complex roots are   0± 3 i ,0 ± 3 i

<em>Step(ii)</em>:-

The complementary function  

              y = e^{\alpha x } ( c_{1} + c_{2} x ) cos\beta x + (  c_{3} +c_{4} x) sin\beta x

The general solution of the given differential equation

          y = e^{0 x } ( c_{1} + c_{2} x ) cos3 x + (  c_{3} +c_{4} x) sin3 x

The general solution of the given differential equation

   y =  ( c_{1} + c_{2} x ) cos3 x + (  c_{3} +c_{4} x) sin3 x

2.49 Encuentre los errores en cad uno de las siguientes aseveraciones: a) las probabilidades de que un vendedor de automóviles v
Yuki888 [10]

Answer:

Step-by-step explanation:

a) Si se suman las probabilidades de venta, es decir:

Probabildad de vender 0 auto ( es decir que no vendió) = 0,19

Probabildad de vender 1 auto                                              = 0,38

Probabildad de vender 2 autos                                            = 0,29

Probabildad de vender 3 autos                                            =0,15

Da por resultado:  1,01

1,01 > 1  

Ninguna probabilidad puede ser mayor que

b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad

d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras  tipo ( diamante, trebo, corazones y el otro).

La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.

La probabilidad de que sea corazones y negra s 1/4*1/2  = 1/8

Luego no hay error en esta aseveración
