Answer:
9
Step-by-step explanation:
We know that
The balls hits the ground when h(t)=0, so
Note I only considered the positive case because time must be positive.
The sum of the complex number 12 – 5i and –3 + 4i is 9 - i
<h3>How to sum complex number?</h3>
The sum of 12 – 5i and –3 + 4i can be done as follows:
Therefore,
12 - 5I + (-3 + 4i)
12 - 5i - 3 + 4i
Hence,
combine like terms
12 - 3 - 5i + 4i
Finally,
9 - i

Answer:
y = 4
Step-by-step explanation:
Note that A and B have the same x-coordinate: 1. This means that AB is a vertical line through x = 1. The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5. Thus, it's just y = 4.
Review: y = 4 bisects AB and represents a horizontal line.
