Answer:
c
Step-by-step explanation:
-3-- or just + -3 * -1 since xy are not separated by anything so its multiplication
Answer:
(x+9)^2+(y+6)^2=36
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) is the given center and r is the radius of the circle.
Given a center of (-9,-6) we have (x+9)^2+(y+6)^2=r^2 so far.
Since the diameter is 12, half of that is the radius which is 6, so the equation of the circle is (x+9)^2+(y+6)^2=36 (as 36 is 6^2)
Answer:
Parameter.
Step-by-step explanation:
Parameter is a value that characterizes population or sample in a given data. Parameter gives extracts from the entire population. This is very important in statistical analysis. Parameter is fixed and unknown numerical value.
Step-by-step explanation:
calculate the area of the shape(s) on the inside and then the area of the sphape on the outside, then subtract the inside's area from the outside shape. im still working on this one, check back in a bit.
