Easy
the radius is the distance from the center to a point on the circle
we are given
center=(7,1)
a point=(8,7)
find the distance
distance formula
D=
so the distance between point and center is radius
D=
D=
D=
D=√37 units
radius is √37 units

Answer:
x²+2x-3=0
According to Vieta's formula:
x²-(Sum of roots)x+(product of roots)=0
Sum of roots=-3+1=-2
Product of roots=-3×1=-3
The equation is x²-(-2)x+(-3)=0
x²+2x-3=0
Answer:
It will take turtle 
to reach the pond.
Step-by-step explanation:
Given:
A turtle can walk 1/12 of a kilometer in an hour.
The turtle is 1/5 of a kilometer away from a pond.
Now, to find the time it will take the turtle to reach the pond.
<u>Speed</u> of turtle = 
<u>Distance</u> of turtle from the pond = 
Now, to get the time it will take turtle to reach the pond we put formula:
Therefore, it will take turtle to reach the pond.
