it is in simplest form, but if you would like the decimal, it is 0.344

The value of b^2-4ac is known as the discriminant of a quadratic function, and can tell you how many roots exist of this function depending on what it is equal to.
Start by moving the -1 to the other side, as we need this function to equal zero.
2x^2 + 3x + 1 = 0
This is now the standard form ax^2 + bx + c = 0. Plug each value that corresponds into the discriminant equation.
b^2-4ac
(3)^2 - 4(2)(1)
9 - 8
1
The value of the discriminant is 1, meaning that two real roots exist for the function described.
Answer:
B
Step-by-step explanation:
I did this already lol
Answer:
0.0005729
Step-by-step explanation:
since the exponent is negative, move the decimal four units to the left to get:
0.0005729
The shapes are irregular and is formed by a octagon and a rectangle (square kinda = rectangle)
But given your multiple choice...
1) Shape 1 and 2 isn't congruent so false.
2) Shape 1 and 2 don't share the same coordinates because of a prior translation so false.
3) Shape 1 and 2 isn't congruent so false.
4) Shape 1 could be translated onto shape 2, but it still would not be congruent, so true.
Therefore the 4th one is true.
