Answer:
i think it the third one but i don't know i'm not in collage math class so...
Step-by-step explanation:
Answer:
C. Either positive or negative
Answer:
Point B must be at the same distance from the the origin as point A.
Step-by-step explanation:
Coordinates of point A = (3, 3)
When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)
Distance from origin to point A = 
Similarly, distance of point B from the origin =
Therefore, distances of both the points from the origin are same.
Point B must be at the same distance from the the origin as point A.
So first let me assume that the Total profit of the racquets are 8 percentage and not individually.
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40
19.445 is the answer as you can see...
first you need to see the 1 decimal place which is like the number smaller than 1, eg:0.5,0.4 then later you see the 2 decimal place and later third on order to find out...
