Answer: second option.
Step-by-step explanation:
The equation of the circle in "Standard form" or "Center-radius form" is the following:
Where the center of the circle is at the point (h, k) and the radius is "r".
In this case you have the following equation of the circle written in Standard form:
You can identify that:
Therefore, the center of the given circle is at this point:
The answer is the first choice:
As the x-values go to positive infinity, the functions values go to negative infinity
<span>D-The domain of the function is all real numbers less than or equal to 0.</span>
Let the original bill be
, then the final bill after the charges been added are
, where
is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)
The range of the original bill is
200 <
< 800, subtract each term by 25
175 <
< 775, divide each term by
145.83 <
< 645.83
Hence, the range of the original bill is between $145.83 and $645.83
