Answer: a. Radius of circle = 
b. The equation of this circle : 
Step-by-step explanation:
Given : Center of the circle = (3,10)
Circle is passing through (12,12).
a. To find the radius we apply distance formula (∵ Radius is the distance from center to any point ion the circle.)
Radius of circle = 
Radius of circle = 
i.e. Radius of circle =
b. Equation of a circle = 
, where (h,k)=Center and r=radius of the circle.
Put the values of (h,k)= (3,10) and r= , we get
∴ The equation of this circle :
Y= -2x-8

Answer:
The answer is 33.2*F (72.3*F - 39.1*F because the temp. is *dropping* 39.1*F)
Step-by-step explanation:
If there is a negative change in temp. then that is just like subtracting the change from the base degree (F)
Answer:
Ted is correct. Maggie made mistakes while trying to isolate x for both equations.
Step-by-step explanation:
For 3x-2=0, in order to move -2 to the left side, Maggie had to add 2 on both sides because -2+2=0. The same problem is seen for x+5=0. Maggie had to subtract 5 on both sides because +5-5=0
