Answer: The value of a is 1. The value of b is -1. The value of c is 1. The value of the discriminant is -3. The quadratic function will not intersects the x-axis.
Explanation:
The standard form of a quadratic equation is,
The given function is,
It can be written as,
By comparing this equation with the standard form of quadratic equation. we get,
The formula for discriminant is,
The value of the discriminant is -3.
If D<0, it means the function have no real roots.
If D=0, it means function have one real roots.
If D>0, it means function have two real roots.
Since D<0 it means the function have no real roots. So the function will not intersect the x-axis at any point.
There are 8 faces on the figure.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.
Then, there is another side that equals 4 x 4 which is 24.
Another side equals 4 x 6 which is 24.
Another one equals 6 x 6 which is 36.
Another side equals 6 x 6 which also equals 36.
Another side equals 10 x 6 which is 60.
The last side is 10 x 6 which equals 60.
Which should add up to 392 in.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.
