Answer: A
Explanation:
Because the center of circle A is (0,1) and circle B is one unit down, it would be x^2+y^2=1 because the center of circle B is (0,0). (The equation for a circle is (x-h)^2+(y-k)^2=r^2 with h and k as coordinates of the center of the circle and r as the radius.)
First you multiply 6 by 20, then add 1 which we should now have 121, then 6.1 which would equal the 6 1/10, multiply 6 x 10 now we have 60 add the 1, we have 61. Now 6.07 would equal 6 7/100 which would now be 6 x 100, which we get 600...now as before remember this rule, when ever you do a mixed fraction you always add the numerator. So now we have 601.
So the answer would be 601, 121, and 61. Hoped this helped :)
Answer:
1
Step-by-step explanation:
The product of any nonzero real number and its multiplicative inverse (reciprocal) is always 1. This is called the multiplicative identity or the identity element of multiplication.
