Answer:
D 19,905
Step-by-step explanation:
19,905.22×25%=4976.31
19905.22-4976.31=14,928.91
14928.91×8%=1194.31
14928.91-1194.31=13734.6
Let's find at first
Let's find (a+b)(a-b)....
we should divide both side of fraction by b and we will get the following:
and (a-b)/(a+b) is same as (1/[(a+b)/(a-b)]) so we can use previous answer and finally we will have (a-b)/(a+b) = 1/[ (tanx + 1) / (tanx - 1)] = (tanx - 1)/(tanx + 1) and final answer will be this:
I think it was be 220 because if theres 55 in a 10 stack it should be 55x4
Answer:
The center is (20, 0.05) radius = 9
Step-by-step explanation:
The center is (20, 0.05) radius = 9
from the general form of the equation:
(x - h)^2 + (y - k)^2 = r^2
we see that r^2 = 81
so r = 9
