Answer:
Step-by-step explanation:
Rotation by -90° about the origin is the transformation ...
(x, y) ⇒ (y, -x)
So, your pre-image points are ...
A'(6, 3) ⇒ A(3, -6)
B'(-2, 1) ⇒ B(1, 2)
C'(1, 7) ⇒ C(7, -1)
Answer:

Step-by-step explanation:
The given function is

By the triangle inequality property,

and the alternate triangle inequality property;

We apply this property to get:

Expand parenthesis to get:

Simplify to get:

Group similar terms to get:


When x>5,

That's;

2,640,000. Because the 4 is in the ten thousands place and should be rounded up
option 1 is correct [5root2]
