Answer:
Parabola with vertex at point (1,0) that goes to the right (see attached diagram).
Step-by-step explanation:
Let the complex number z be

then

and

Thus,

Square it:

This is the equation of parabola with vertex at point (1,0) that goes to the right.
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
Answer:
C
Step-by-step explanation:
(c + 1)(c+1) = c² + c + c + 1 = c² + 2c + 1
Answer:
4x-9
Step-by-step explanation:
6+7x-4-3x-11
Combine like terms: 7x-3x = 4x
:6-4-11 = -9
Combine them together and you get 4x-9

Answer:
50x32=1600
Step-by-step explanation:
because 2x0=0, 2x50=100, 30x0=0, 30×50=1500 add together, than get 1600
