The point B(1, 1) is rotated 90° counterclockwise around the origin. What are the co
of the resulting point, B'?
B' = (
1
)

Given that the point B is (1,1) is rotate 90° counterclockwise around the origin.

We need to determine the coordinates of the resulting point B'.

Coordinates of the point B':

The general rule to rotate the point 90° counterclockwise around the origin is given by

The new coordinate can be determined by interchanging the coordinates of x and y and changing the sign of y.

Now, we shall determine the coordinates of the point B' by substituting (1,1) in the general rule.

Thus, we have;

Coordinates of B' =

Thus, the coordinates of the resulting point B' is (-1,1)

if she drove away she would have to drive 14 hours, or if it were i the same direction she would have to drive 2 1/2 hours

Step-by-step explanation:

8 1/4 + 5 3/4 = 14

8 1/4 - 5 3/4 = 2 1/2
