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

Answer:
2.79
Step-by-step explanation:
The temp after 15 minutes is 225 degrees because the initial temp plus the rate time the number of minutes gives the current temp. in this case, 75 + 10(15) = 225
therefore, the temp after t minutes can be represented by the equation f(x) = 10t + 75
