Initially, the point (-3,4) is in the second quadrant of the cartesian plane. If the rotation is about point (-3,0) at 90 degrees, you find a point that when connected to (-3,4) makes two lines perpendicular to each other. Since the direction is counterclockwise, you move 3 points to the left, then 4 points down. That would be (-7,0). The answer is A.
Let's say that the coordinates of the squirrel are: (x, y)
Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.
To work out the midpoint you do:
(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.
We can use this to form an equation .
So the sum of the x coordinates of the tree and the squirrel = -1 :
x-coordinates of the squirrel:
<em>(now solve for x)</em>
y-coordinates:
<em>(now solve for y)</em>
So the coordinates of the squirrel are: (1, 2)

Answer:
(1, 2)
D. no solution
Because they never found each other, the point they cross on is the solution.
You would have to do 18x2 then 14x2.
Answer:
AB = 8.0
Step-by-step explanation:
Law of Sines
AB/sin53 = 7/sin44
multiply both sides by sin53
AB = 7/sin44 * sin53
use calculator
AB = 8.047766798861355
Rounded
AB = 8.0
