Circumference = πD
Circumference of the pond = π(4.5) = 14.14 ft (nearest hundredth)
Answer: 14.14 ft
Answer:
Step-by-step explanation:
The coefficients of the quadratic x^2 + 7x + 3 are a = 1, b = 7 and c = 3.
The discriminant is b^2 - 4ac, or 49 - 4(1)(3), or 49-12, or 37.
Because the discriminant is positive, we know that this quadratic equation has two real, different solutions.
-7 ± √37
x = --------------- => x = (-7 + √37)/2 and x = (-7 - √37)/2
2
In words: This quadratic equation has two real, unequal solutions involving the radicand 37.
Answer:
Step-by-step explanation:
The equation of a circle is 
where 
is the center of the circle and 
is the radius of the circle.
Given that 
and it passes 
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
Therefore, if the length of the radius is 
units, then 
, making the final equation of the circle
