<span>Rules for rotating points about the origin
1. The point (a,b) rotated 90° counterclockwise about
the origin
becomes (-b,a).

Answer:
The answer 2400.
Step-by-step explanation:
2×10^3=2×1000=2000

Answer:
10ac
Step-by-step explanation:
We have been given the expression a · c · 5 · 5
We can multiply 5 with 5 and get 25.
Thus, the expression becomes
a · c · 5 · 5= ac25
We can rewrite the expression using commutative property
25ac = 25ca
Therefore, the given expression is equivalent to 25ac and 25ca.
Hence, 10ac is not the correct form.
First option is correct.
