Answer:
sqrt(14)

Explanation:
The absolute value of a complex number a+bi can be calculated as follows:
|a+bi| = sqrt(a^2 + b^2)
we have:
a = -4
b = -sqrt(2) i

Substitute with the values in the above equation to get the absolute value as follows:
|a+bi| = sqrt [(-4)^2 + (sqrt(2) i)^2] = sqrt(14)

Find the component form of the vector that translates P(4,5) to p'.
Veronika [31]

Answer:

Component form : (-7 , 2)

Step-by-step explanation:

P(4 , 5) = P'(4 +x , 5+y) = P'(-3 , 7)

4 + x = -3

    x = -3 - 4

    x = -7

5 + y = 7

     y = 7 - 5

     y = 2

Vector form : -7i + 2j

Component form : (-7 , 2)
