Answer:

The real number 'a' = 32

The real number 'b' = 0

Step-by-step explanation:

Product of a number of a number and its conjugate = a + bi

The number is = -4 + 4i

Conjugate of this number is = -4 - 4i

Product of the number and it's conjugate

= (-4 + 4i)(-4 - 4i)

= -4(-4 - 4i) + 4i(-4 - 4i) [By distributive property]

= 16 + 16i - 16i - 16i²

= 16 - 16(-1)

= 16 + 16

= 32

a + bi = 32 + (0)i

By comparing both the sides,

a = 32

b = 0

RUDIKE [14]

Answer:

y = 1/9 x z^3

Step-by-step explanation:

y is jointly proportional to x and z^3

y = k * x * z^3 where k is the constant of proportionality

y =12, x = 4 and z =3

12 = k * 4 * 3^3

12 = k * 4 * 27

12 = k * 108

12/108 = k

1/9 = k

y = 1/9 x z^3
