Answer:
- 20 + 8i
Step-by-step explanation:
Noting that i² = - 1
Given
[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket
= ( 6i + 9 + 4i - 5 ) × 2i
= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i
= 20i² + 8i
= 20(- 1) + 8i
= - 20 + 8i
Rotation and reflection are instances of transformation
See attachment for the new position of 
From the question, we have:


The rule of 90 degrees clockwise rotation is:

Using the above transformation, the new points would be



The next transformation is reflection over the x-axis
The rule of this transformation is:

So, the new points would be:

Answer:
Step-by-step explanation:
m: y = -2x + 4
n: y = x - 1
l: y = 4
p: x = -4
7.3 is the range
Step-by-step explanation:
The range of a set of data is the difference between the largest and smallest values.
The chord that goes through the center of a circle, the diameter, is the longest chord in a circle. Any other chord will be shorter than this. The farther a chord is away from the circle, the shorter it will be. This means that chord CD is shorter than chord AB.
