Answer:
41
Step-by-step explanation:
We know that complex numbers are a combination of real and imaginary numbers
Real part is x and imaginary part y is multiplied by i, square root of -1
Modulus of x+iy =
Here instead of x and y are given 9 and 40
i.e. 9+40i
Hence to find modulus we square the coefficients add them and then find square root
|9+49i| =
By long division method we find that
|9+40i| =41
The answer is C:(5,-2),(3,1),(4,2)
Answer:
$720
Step-by-step explanation:
I = Prt
I = (9000)(0.04)(2)
I = 720
The second one would prove they are parallel. This is because it uses angles touching both of the parallel lines and uses correct Angle Properties
