Answer:
A ) The Equation of the circle (x−10)2+(y−24)2=676
Step-by-step explanation:
step1:-
The equation of the circle whose center is (a,b) and radius r is
in this circle equation centre is (g,f) = (10,24)
and formula of radius of a circle is
r =
Step2:-
The Equation of the circle (x−10)^2+(y−24)^2=676
Answer:
Part a. The graph does not model a proportional relationship.
Part b. The values in table model a proportional relation.
3.5 minutes per mile.
Step-by-step explanation:
Part a.
The graph shown in the question representing Janet's data is not a straight line although it passes through the origin.
That is why the rate of change of distance with time is not constant.
Therefore, the graph does not model a proportional relationship.
Part b.
If we plot the data in the table using distance in miles along the y-axis and time in minutes along the x-axis, then we will get a straight line passing through the origin.
So, the values in the table model a proportional relation.
Now, Tarik's unit rate in minutes per miles will be minutes per mile. (Answer)
