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)
Answer:
The late fee per day for the book
Step-by-step explanation:
2 + .25x
The 2 is the fixed rental for the book
.25x is the late fee per day where .25 is the charge per day and x is the number of days
You find the slope by putting the points in the formula y2-y1/x2-x1
when you plug them in it should look like this
-4 -1/8-8
then you would add or subtract, when you do you would get
-5/0
this can't be divide so the slope of this 2 points is undefined
Hope this helped
