Answer:
The correct option is 1.
Step-by-step explanation:
If a quadratic equation is defined as
then the quadratic formula is
The given equation is
Here, a=1, b=-2 and c=-3.
Substitute these values in the above formula.
Therefore, the correct option is 1.
The eigenvectors are (1 + i)/4 and (1-i)/4.
- A matrix is an organized, rectangular grouping of real or complex integers or functions.
- The unique collection of scalars known as eigenvalues is connected to the system of linear equations. The majority of matrix equations employ it. The German term "Eigen" signifies "appropriate" or "characteristic." Therefore, the word "eigenvalue" can also be used to refer to a suitable value, a latent root, a characteristic value, or a characteristic root. The eigenvalue is a scalar that is used to alter the eigenvector, to put it simply.
- The non-zero vectors that do not change direction when a linear transformation is performed are called eigenvectors. It is only modified by a single scalar component.

X(x-20)=12000
x^2 - 20x = 12000
x^2 - 20x - 12000 = 0
(x - 120)(x + 100) = 0
x = -100, 120
so the width is 120 ft
The domain of a function is the set of x values for which it is defined. The range of the given graph will be -2≤x<7.
<h3>What is the domain and range of a function?</h3>
The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.
As it can be seen that the value on the y-axis is defined for every value of x between -2 to 7, also the value of x is also defined for x=-2.
Hence, the range of the given graph will be -2≤x<7.

Hello! :)
To solve you equation, we will first Distribute
(-3) (w) + (-3) (3) + 4w
= -3w + -9 +4w
Now, we will combine like terms
-3w + -9 + 4w
= (-3w + 4w) + (-9)
= w + 9
Hope this helped you!
