Answer:
The conjugate is 2+5i and the product is 29.
Step-by-step explanation:
The conjugate of a complex number is
Our complex number is 2-5i.
Here, a = 2 and b = -5
Thus, the conjugate of 2-5i is
Using this rule:
And the fact that
We can find the product of any complex number and its conjugate:
As our complex number is , the product with its conjugate will be
Answer:
(-3, -6, 0)
Step-by-step explanation:
3(-1) = -3
3(-2) = -6
3(0) = 0
Step-by-step explanation:
Supplementary angle adds up yo 180°
So angle 2 is supplementary to angle 3
Answer:
The location of the point is between Quadrant II and Quadrant III
Step-by-step explanation:
we know that
The abscissa refers to the x-axis and ordinate refers to the y-axis
so
in this problem we have
the coordinates of the point are
see the attached figure to better understand the problem
The location of the point is between Quadrant II and Quadrant III
Answer:
3.2
Step-by-step explanation:
0 = 2t - 8/5
8/5 = 2t
16/5 = t
3.2 = t
