Answer:

Its A (-1,2)

Step-by-step explanation:

180 degree rule is (-x,-y)

point D is (1,-2)

Since the two is already a negative you have to turn it into a positive so that's why it would be (-1,2).

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.

$\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}$

$\frac{t}{24}=\frac{4}{8}$

$\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24$

$t=\frac{4}{1}\cdot 3$

$t=12$

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
