-92
Step-by-step explanation:
If a quadratic equation has the following form:
then its discriminant D is defined as
In our given quadratic equation, a = 4, b = -2 and c = 6, so its discriminant is
Note: The value of the discriminant D will determine the characteristics of the roots of the quadratic equation according to the following rules:
there will be 2 real roots
there will be 1 real root
there will be 2 imaginary roots
Hence our given quadratic equation will not have any real roots but only imaginary ones.
Answer:
Step-by-step explanation:
1 package contains 16 slices. A dozen packages is 12 packages. Therefore, a dozen packages will contain 16×12 slices which is 192 slices.
We can say that the 8 foot base is the adjacent side.
We can say that the 5 foot altitude is the opposite side.
the tangent of the base angle = 5/8 = .625
Therefore the angle equals
arc tangent (.625) = 32.005 degrees
