Answer:

The circles radious increases

The circles moves left

The circles moves down

Step-by-step explanation:

The equation of a circle can be written as $(x-a)^2+(y-b)^2=r^2$ , where "r" is the radious, and (a,b) are the coordenates in the axis x and b respectively.
Then, in the first circle the coordenates are (0,7), which means that the circle will be center there, and the radious is 7 ( $\sqrt{49}$ ).
The second circle have different coordenates: (-5,4), which means that the circle has moved left (from 0 to -7 in the x axis) and down (from 7 to 4 in the y axis). Additionally, its radious has increased from 7 ( $\sqrt{49}$ , from 8 ( $\sqrt{64}$ ).
See the attached figure please.
Then, the <u>correct answers</u> are:

The circles radious increases (from r=7 to r=8)
The circles moves left (from x=0 to x=-5)
The circles moves down (from y=7 to y=4)

vladimir1956 [14]

Answer:

-
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255
now, we can find total number of guests
Total number of guests =(total number of guests called for room services)+(total number of guests did not called for room services)
so,
total number of guests is
=170+255
=425
now, we can find percentage
percentage of the guests at this hotel called for room service yesterday is %40
So,
The percentage of the guests at this hotel called for room service yesterday is 40%
