Olegator [25]

Complete question:

<em>What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di) </em>

<em>choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2</em>

<em />

<em>Option D</em><em> is correct. </em> The value of c and d for the expression to be real are -3 and -2 respectively

Given the expression

$i(2 + 3i)(c + di)$

Expand the expression

$=i(2 + 3i)(c + di)\\=(2i+3i^2)(c+di)\\=(2i+3(-1))(c+di)\\=(2i-3)(c+di)\\=2ic+2di^2-3c-3di\\=2ic-2d-3c-3di$

Collect the like terms

$=2ic-3di-2d-3c$

For the resulting function to be real, then the imaginary part must be zero i.e.

$2ic-3di=0\\2ci = 3di\\2c = 3d\\c=\frac{3d}{2}\\$

If d = -2, then;

$c=\frac{3(-2)}{2}\\c=\frac{-6}{2}\\c= -3$

Hence the value of c and d for the expression to be real are -3 and -2 respectively.

How far below the bridge will kate eventually be hanging, once she stops oscillating and comes finally to rest? assume that she

shepuryov [24]

The distance below the bridge that kate will eventually be hanging, once she stops oscillating and comes finally to rest is: d = mg/k + L.

<h3>Distance</h3>

LetForce exerted by a spring=F=kx

Let x = (d – L)

Let d= Total length of the bungee cord

Let set this equal to the gravitational force

F(spring) = k(d – L)

F(gravity) = mg

Hence:

k(d – L) = mg

(d – L) = mg/k

d = mg/k + L

Inconclusion the distance below the bridge that kate will eventually be hanging, once she stops oscillating and comes finally to rest is: d = mg/k + L.

Un camión traslada 12 vehículos. Algunos son autos y otros son camionetas. Cada auto tiene una masa de 2 toneladas y cada camion

bagirrra123 [75]

Encontrando y resolviendo un sistema de ecuaciones, veremos que hay 9 camionetas y 3 autos.

Sabemos que hay 12 vehículos en el camión.

Definamos:

a = número de autos
c = número de camionetas.

tal que a + c = 12

La masa total será:

a*2 ton + c*3 ton

Y sabemos que el camión lleva 33 toneladas, entonces tenemos:

a*2 ton + c*3 ton = 33 ton

Así encontramos el sistema de ecuaciones:

a + c = 12

a*2 ton + c*3 ton = 33 ton

Para resolverlo, primero aislamos una de las variables en una de las ecuaciones, aislemos a en la primera:

a = 12 - c

Ahora reemplazamos esto en la otra:

(12 - c)*2 ton + c*3 ton = 33 ton

24 ton + c*1 ton = 33 ton

c*1 ton = 9 ton.

c = 9

Es decir, hay 9 camionetas.

Entonces los 3 vehículos restantes son autos.

Hay 9 camionetas y 3 autos.
