Determine the scale factor used in the dilation of a figure if vertex A(9,-18) has the image A'(6,-12). a. 2/3

b. 1/2

c. 1/3

d. 3/4

answer: c i think

step-by-step explanation:

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
