Answer:
I really do love this type of questions....but in here it seems that the question in either incomplete or the answers are mixed...cause the DATA'S showing 8 digits while THE AGE OF PEOPLE is showing 7 digits
x2+y2−2x−80=0
Write the problem as a mathematical expression.x2+y2−2x−80=0
Add 80 to both sides of the equation. x2+y2−2x= 80 Complete the square for x2− 2x. Tap for more steps...(x−1)2−1 Substitute (x−1)2−1 for x−2x in the equation x2+y2−2x =80 .(x−1)2−1+y2=80 Move −1 to the right side of the equation by adding 1 to both sides.(x−1)2+y2=80+1Add 80 and 1.(x−1)2+y2=81
This is the form of a circle. Use this form to determine the center and radius of the circle.(x−h)2+(y−k)2=2Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.r=9h=1k=0 The center of the circle is found at (h,k). Center: (1,0)These values represent the important values for graphing and analyzing a circle. Center: (1,0)Radius: 9
Answer:
2
Step-by-step explanation:
Currently, Peter has run a total distance of . His goal is 10 km, as stated in the problem, which equates to 10,000 meters. Thus he will need to run more meters to achieve his goal. Since the track is 400 meters, he needs to run around the track more times to achieve his goal.
A) 31 degrees
b) 118 degrees

rose m
1.63+m
dropped 0.12
1.63+m-0.12
1.63-0.12+m
1.51+m
current price=1.51+m
