What is the product?
[4 3 -1 -1] x [-3 1 -2 -2]

What Is The Product?[4 3 -1 -1] X [-3 1 -2 -2]

Answers

Answer 1

Answer:

Option A

|-6 -2|

|1 1|

Step-by-step explanation:

This is a product of a matrix.

So for the first number on the first row, we have;

(4 × -3) - (3 × -2) = -12 + 6 = -6

For the second number on the first row, we have;

(4 × 1) - (3 × 2) = 4 - 6 = -2

For the first number on the second row, we have;

(-1 × -3) - (-1 ×-2) = 3 - 2 = 1

For the second number on the second row, we have;

(-1 × 1) - (-1 × 2) = -1 + 2 = 1

Thus, we now have;

|-6 -2|

|1 1|

Answer 2

Answer: It's B, as in [ -18 10 5 -3]

Step-by-step explanation: I don't exactly wanna explain the entire process of multiplying matrices, but I ran it through multiple matrix calculators so I know it's right

ExplanationPoint-Slope Form

[tex]y-y_1=m(x-x_1)[/tex]

Given the x1 and y1 = given point.

Substitution x1 = 2 and y1 = -8 in the equation.

[tex] \begin{cases} x_1 = 2 \\ y_1 = - 8 \end{cases} \\ y - ( - 8) = - 4(x - 2) \\ y + 8 = - 4(x - 2)[/tex]

Hence, the solution is C choice.

2/5

Hope this helps!!!!

Answer:

2/5

Step-by-step explanation:

The y-intercept is the number being added or subtracted in the equation when you have y = mx + b. For example, in the equation y = 9x - 4, the y-intercept is -4, and in the equation y = 3x + 7, the y-intercept is 7. The number being added in this case is 2/5, so it is the y-intercept.


You use substitution to solve a system of equations and,
after simplifying, end with a statement that says 7 = 7.
Describe what this statement means about the number of
solutions and about the graph of the system.

Answers

Answer: y - 2x = -7

Step-by-step explanation:

7=7

System of equations are independent, if 2nd equation is not multiplication of firstequation by some number . ... Simplify the 2nd equation: ...c y - 2x = -7

... If you solve the equationsalgebraically and you get a solution such as 5=5, then ... If you use either method and end up with astatement that's always true    i hope this helps

Sample Response: Since the statement is true, there are an infinite number of solutions to the system. This statement also indicates that the lines are equivalent.

Given:

The inequality is

[tex]c\leq 7[/tex]

Where, c is the number of cars in the parking lot.

To find:

The graph for the given inequality.

Solution:

We have,

[tex]c\leq 7[/tex]

Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.

Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.

In the graph of the given inequality, there are close circles on  0,1, 2,3,4, 5,6,7 as shown in option D.

Therefore, the correct option is D.

Evaluate the trigonometric function of the quadrant angle, if possible. (If an answer is undefined, enter UNDEFINED.) sin 0

Answers

Answer:

The answer is below

Step-by-step explanation:

The trigonometric function of a quadrant angle can be gotten using a unit circle. After measuring the angle to the corresponding unit circle, the x coordinate is the cosine of the angle while the y coordinate is the sine of the angle.

sec(π): The angle π = 180°, corresponds to the point (-1, 0) on the x axis. Hence cosπ = x coordinate = -1, sinπ = y coordinate = 0

secπ = 1 / cosπ = 1 / -1 = -1

cotπ = cosπ / sinπ = -1 / 0 = undefined

tanπ = sinπ / cosπ = 0/-1 = 0
