Answer:
Distance between two consecutive tick marks is 0.05 units.
Step-by-step explanation:
We are given the following information in the question:
It is given that there are 20 ticks between two consecutive number.
Let n and n+1 be the consecutive number.
Formula:
Distance between two ticks =

Thus, distance between two consecutive tick marks is 0.05 units.
Answer:
6a
Step-by-step explanation:
replace x with -a
-2a -6(-a)
-2a +8a
6a
The chord length is the same as the radius, so R^2 = 9.
Area = (1/2)(9)(pi/3 - sqrt(3)/2) = (3/4) (2 pi - 3 sqrt(3))
Pick any value in the y column of the table. I'm going to pick 81. Divide the value you picked by the previous y value, which in my case would be 9
Dividing the values gives: 81/9 = 9
So the base is 9. We multiply each y value by 9 to get the next y value
Eg: to go from 1/81 to 1/9, we multiply by 9. Same for 1/9 to 1, and so on.
Answer: Choice B) 9
Note: This trick only works because x is increasing by 1 each time
Answer:
10
Step-by-step explanation:
