Answer:
Domain of the function is the set of whole numbers.
Step-by-step explanation:
The given function is
where, c represents the cost of the yearly subscription and m is the number of magazines.
We need to find the domain of the function.
Domain is the set of inputs. In other words domain of the function is the set of m values.
Number of magazines always a whole number (0,1,2,....) because the number of magazines can not be a decimal or negative value.
Therefore, the domain of the function is the set of whole numbers.
Answer:
C
Step-by-step explanation:
I. a // b because m∠2 is on a 180° line, which splits the line into two sections, both being 90°. If m∠1=m∠2, then m∠1 is also 90°. The lines a and b are parallel from each other.
II. since m∠1 is 90°, and for a line to be perpendicular to the other line, they would have to be at a 90°. So, a⊥c because they intersect each other at a 90° angle.
Answer:
Step-by-step explanation:
The information that we know about the circle is the following:
center of the circle: (5, -2)
radius:
We use the general form for the equation of a circle whose center is at the point :
In this case since the center of our circle is at (5, -2), we conclude that:
and
so we substitute this values, along with the value for the radius:
simplifying the expression we get the equation of the circle:
395/1000 will reduce down too 79/200
i have no ideaaaaa HAHAHAHA
