When you write the equation of a circle in the form

Then the center has coordinates
and the radius is 
So, in your case, the center is (5,-3) and the radius is 5.
The nature of the roots of a quadratic equation may be readily determined through the use of its discriminant,
D = sqrt (b² - 4ac)
We can tell if the quadratic equation does not have a real root it the radicand is negative. Therefore, the answer is letter A.
Answer:
zero
Step-by-step explanation:
I remember it as: whenever you have 0 first in the expression, the answer is 0.
So, if you tried to graph 0/90 using rise over run, it would be a horizontal straight line, so there would be no slope - 0.
If you tried to graph 90/0, it would be a vertical line because you can't tell what slope it has - undefined slope.
I hope that helps.
Answer:
C. √16,200 feet
Step-by-step explanation:
According to Pythagorean theorem
c^2 = a^2 + b^2
Home First and Third is formed a right triangle with 2 equal sides = 90 ft
so
c^2 = 90^2 + 90^2
c^2 = 8100 + 8100
c^2 = 16,200
c = √16,200
Answer
C. √16,200 feet
