Answer:
n = (1/2)(-1 ± i√2)
Step-by-step explanation:
Among the several ways in which quadratic equations can be solved is the quadratic formula. Putting to use the coefficients {12, 12, 9}, we obtain the discriminant, b^2 - 4ac: 12^2 - 4(12)(9) = 144 - 432 = -288. The negative sign of this discriminant tells us that the quadratic has two unequal, complex roots. These roots are:
-b ± √(discriminant)
n = ---------------------------------
2a
Here we have:
-12 ± √(-288) -12 ± i√2√144 -12 ± i12√2
n = ---------------------- = ------------------------ = --------------------
2(12) 24 24
or:
n = (1/2)(-1 ± i√2)
That’s false, if you raise a number that’s less than 1 to the second power, you’d get a lesser number.
For example, if you raise 1/2 to the second power, you’d get 1/4
With a given radius you can multiply by 2 and simply get the diameter. Getting the diameter of the circle would then allow you to use the equation pi(24.5). You can round pi to 3.14. 3.14*24.5=76.93. The circumference is 76.93.
