Answer:
Step-by-step explanation:
The discriminant is used to determine the number and nature of the zeros of a quadratic. If the discriminant is positive and a perfect square, there are 2 rational zeros; if the discriminant is positive and not a perfect square, there are 2 rational complex zeros; if the discriminant is 0, there is 1 rational root; if the discriminant is negative, there are no real roots.
The roots/solutions/zeros of a quadratic are where the graph goes through the x axis. Those are the real zeros, even if they don't fall exactly on a number like 1 or 2 or 3; they can fall on 1.32, 4.35, etc. They are still real. If the graph doesn't go through the x-axis at all, the zeros are imaginary because the discriminant was negative and you can't take the square root of a negative number. As you can see on our graph, the parabola never goes through the x-axis. Therefore, the zeros are imaginary because the discriminant was negative. Choice C. Get familiar with your discriminants and the nature of quadratic solutions. Your life will be much easier!
Answer:
37.66 Hours
Step-by-step explanation:
113÷ 3= 37.66
she watched it for 37.66 hours 1/3 times. each time she watched it for 37.66 hours and since she watched it 3 times it added to a total of 113 hours. hope this helped
3x because 3x+2x=5x hope this helps
Correct answer is D.
Line x = a is parallel with y-axis and passes through the point (a,0).
So our line is parallel with y-axis and passes through the point (6,0).
8. You can tell a number is divisible by 2 if it ends in a 0,2,4,6, or 8
