Answer:
Coordinates switch, and the new y-coordinate changes sign
Explanation:
We have point A with the coordinates (-1,2), when we rotate it c90º it becomes (2,1).
What happened? The coordinates switched and the x-coordinate of A (-1) became the y-coordinate of A' (1) and it changed its sign.
Answer:
sqrt3[sqrt3+2sqrt12]=sqrt3[sqrt3+4sqrt3] = sqrt3[5sqrt3= 3x5 =15
Answer:
0.486% of world population lives in Canada.
Step-by-step explanation:
Given: World Population= 7691 million.
Canada Population= 37.4 million.
Now, finding the percentage of world population lives in Canada.

⇒ 
⇒ 
∴ 
Hence, 0.486% of world population lives in Canada.
All you have to do is divide each one by its other number. For example, 5.60 for 8 is the same as one for 0.70. We accomplish this by dividing the 5.60 by 8.
So...
0.70
0.80
0.90
0.75
The first choice is the lowest.
Step-by-step explanation: The <em>intersection</em> of two figures can
be defined as the set of points that is contained in both figures.
In this figure, lines <em>h</em> and <em>i</em> intersect at C or we can
say that C is the intersection of lines <em>h </em>and <em>i</em>.
In this figure, C is the intersection of lines <em>h</em> and <em>i</em>
because C is the point contained by both <em>h</em> and <em>i</em>.
