Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin
ANSWER : <em>Approximately 4.39</em>
WHY? : You must round up the answer "x=4.3939". If thought of like .33X=1.45, then you divide 1.45 by .33
Answer:
D
Step-by-step explanation:
As soon as you see a number times 1 thats how you can find your unit rate, or constant of proportionality.
So since we know that we are going by 32's, we would do 32 23 times, in other words, 32x23
And when you use a CALCULATOR or pencil and paper you get D, which is 736 stairs
