The Answer is C
R is (2,-1)
2*2=4
-1*2=-2
2r=(4,-2)
t=(-7,5)
-7-4=-11
5-(-2)=5+2=7
t-r=(-11,7)
Since we are multiplying r by two, we have to multiply its x and y values by two to be 2r
With t-2r, we have to subtract 2r's x value from t's x value and 2r's y value fro t's y value to get the x value -11 and the y value 7
Therefore, the x and y values for the answer is -11 and 7, and to put them in the proper form required, which is (x,y), input -11 into x's spot and 7 in y's spot, giving you and answer of (-11,7)

Answer:
x are 2,3,4,5,6. Y are -12,-15,-16,-15,-12 .
According to above graph :
so, correct option is C. 6
Answer:
4.46
Step-by-step explanation:
As the circumference of a circle is pi multiplied by the diameter to work out the radius you would first divide the circumference of 28 by pi, which gives you 8.92. This is the diameter, however the question is asking for the radius. To work out the radius you would divide the diameter by 2, which gives you 4.46. This is because the radius is half of the diameter.
1) Divide 28 by pi.
2) Divide 8.92 by 2.
