The graph of a quadratic function y = ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive negative, or zero.

The discriminant is equal to 0.

Step-by-step explanation:

The graph shows the parabola with branches go down in negative y-direction. This gives you that a<0.

Since parabola has one x-intercept, then the equation has two equal solutions and the discriminant is equal to 0.

Zero

Step-by-step explanation:

1. By definition: if the discriminant is negative, the quadratic equation does not have real solutions, it has two imaginary solutions. If the discriminant is zero the quadratic has one solution. If the discriminant is positive, the quadratic equation has two distinct solutions.

2. You can see that the function touches the x-axis, this only happen when the solution of the function is even . Then, the function has only one solution. The discriminant is zero.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
