Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Answer:
13
Step-by-step explanation:
The magnitude of a vector < a, b > is
Given < - 12, 5 > then the length of the side is
=
= = 13
Answer: None
The two sides of 2 and 3 combine to form 2+3 = 5. Imagine laying two sticks out of length 2 and 3. They would form a straight line and not be long enough to bend at the hinge to allow for the other side (size 5) to fit anywhere. A triangle does not form. Instead its simply a straight line. For a triangle to form, any two sides must add up to some value larger than the third side.
Answer:
I could only figure out that the range is the 2nd to last one. Sorry. Hope you get it right!
