Answer: The rule is when rotating 90 degrees, it's (-y, x), 180 degrees is (-x, -y), and 360 degrees is (y, -x). Just plug in the numbers accordingly, and you should get the correct answer. It worked for me <3.

(If A(2, -3), B(3,-2) and point C divides the line segment AB in the ratio of 1: 2, find OC.)

Anna007 [38]

Answer:

A(2, -3) and B(3, -2), o(0, 0) Let C(x, y)

Here c divide AB line in the ratio of 1:2

From the line intersection law, we get x=(m1×x2+m2×x1)/(m1+m2)

and y=(m1×y2+m2×y1)/(m1+m2)

where m1=1, m2=2, x1=2, x2=3, y1=-3, y2=-2;

so x=(3+4)/3

or, x=7/3;

y=(-2-6)/3

or, y=-8/3;

so, oc=√((0-7/3)²+(0-(-8/3))²)

oc=3.54

Shtirlitz [24]

Answer:

4:13

Step-by-step explanation:

First as stated in the problem, mark is looking to find the ratio of Yellow rose bushes planted the Total amount of rose bushes planted; so therefor we must find the total amount of rose bushes planted first.

9+4 = 13.

13 will be our second number, since it is Yellow : total.

Then, we understand that mark plants 4 yellow rose bushes, so 4 is our first number.

Now; we can put our numbers together.

4 to 13 ; $\frac{4}{13}$ , or 4:13.

I really hope this helps! Have an amazing day!
