Think of imaginary numbers on a complex plane as coordinates - take the real part, that's the x coordinate, the imaginary part that's the y coordinate.
Therefore, for the first blank, -1+3i lies in the shaded area, because its coordinates are (-1,3).
And following on from that for the second one, -4i does not lie in the shaded area, since its coordinates are (0,-4).
Tl;dr is taking a complex number a+bi and placing it on a complex plane, it will have coordinates (a,b)
Answer:
ghhhhhh
Step-by-step explanation:
Answer:
We need 232 mL of Compound A
Step-by-step explanation:
We know the ratio
A : B : total
4 3 4+3
4 3 7
We want 406
406 /7 =58
Multiply each part by 58
A : B : total
4*58 3*58 7*58
232 174 406
We need 232 mL of Compound A
