The equation that represent the data in the table shown is y = -2x + 3.

Linear systems are sets of equations associated with each other and that have two or more variables. In linear systems, only linear equations are entered, that is, expressions where the greatest exponent of the unknowns is equal to 1.

A linear equation is in the form:

y = mx + b

Where:

From the table, using the point (0, 3) and (1, 1):

y - 3 = [(1 - 3)/(1 - 0)](x - 0)

y - 3 = -2xy = -2x + 3

and in this problem the realistic answer is the first one, so the solution is $8 dollars

Answer

he trapeziunm is an isosceles trapezoid since there are pairs of congruent base angles ADC and BCD

Lines AB and DC are the bases'

To proof that

WDraw perpendicular line segments from A to P and from B to Q which are perpendicular to line DC

∠APD =∠BQC (Right angle)

That is ∠D ≅ ∠C

Now the perpendiculars AP and BQ are congruent

By AAS Property, triangles APD and BQC are congruent and this implies that the hypotenuses AD and BC are congruent.

Therefore the legs AD and BC are congruent.

The zeros of the quadratic are (1 and 3), the vertex is (2, -1). Draw the parabola with a "solid" line. Shade the "interior" of the parabola.

For the given question;

The inequality of the function is given as;

= x² - 4x + 3

Find the factors;

(x - 3)(x - 1) = 0

x = 1 and x = 3 are the zeros of the equation.

Now, to graph the equation find the point;

Put x = 0; y = 3

Put x = 1; y = 0

Put x = 2, y = -1

Plot the points on the graph and join the points with solid line.

The vertex of the parabola is found at (2, -1).

Thus, the graph of the parabola is plotted.

Thinking and cognition are related to reasoning, which requires using one's intellect. The study of logic focuses on how people can construct logically sound arguments using formal reasoning. Deductive, inductive, and abductive reasoning are three examples of logical reasoning that can be used to further break down reasoning. Aristotle distinguished between logical discursive reasoning (reason proper) and intuitive reasoning, noting that the former may lean toward the subjective and the personal, despite being correct. While logical and intuitive styles of reasoning might clash in certain social and political circumstances, in others they are considered as complimentary rather than competitive.

Answer:

Acute

Step-by-step explanation:

Obtuse angles are angles that are larger than 90 but less than 180

Acute angles are angles that are less than 90 degrees

Right angles are angles that is exactly 90 degrees

Complementary angles are two angles whose sum is 90 degrees

Using this info, it seems the answer to this question is B. Acute because it says "the values returned by inverse to angles larger than 90" and since acute is the opposite of obtuse imma say B but im not too sure

To answer this question we need to remember that:

There's only one angle that gives this result that it is real. Therefore the answer is 112.62

By using trigonometric formulas and integration rules, we conclude that the integral is approximately equal to - 7.764 units.

In this problem we must determine the solution to a definite integral of trigonometric equations, which requires the use of trigonometric formula and integration rules to be found. The integral can be simplified by using the following formulas:

sin⁴ x = (1 / 8) · (3 - 4 · cos 2x + cos 4x)

sin² x = (1 /2) · (1 - cos 2x)

Then, the integral is simplified into this form:

[tex]I = \pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{4} x \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{2} x \,dx[/tex]

[tex]I = \frac{\pi}{8} \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (3 - 4\cdot \cos 2x + \cos 4x) \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (1 - \cos 2x) \,dx[/tex]

[tex]I = \frac{3\pi}{8}\cdot x - \frac{\pi}{4} \cdot \sin 2x + \frac {\pi}{32}\cdot \sin 4x - 4\pi \cdot x - 2\pi\cdot \sin 2x[/tex], for x ∈ [π / 6, 3π / 4]

And the definite integral is:

I = 2.159 + 1.466 - 0.085 - 23.028 + 11.724

I = - 7.764

The definite integral of f(x) = sin⁴ x + 4 · sin² x for x ∈ [π / 6, 3π / 4] is approximately equal to - 7.764.

No. there is not a fixed number of trials. The correct option is B.

A variable with only two outcomes is said to be binary. Examples of binary categorical variables are sex (male/female) and having a tattoo (yes/no).

Each trial must be independent, meaning that it must have a defined number of trials and a constant success rate. Its probability needs to range from 0 to 1.

There are only two conceivable outcomes for each individual. They are either filtered or they are not. We are not interested in learning how many people were screened, though.

It is an inverse binomial, we want to know how many persons will be screened before 10, which is a binomial. Therefore, since there are an arbitrary number of trials, this is not a binomial equation, and option B provides the solution.

Value of x =5 and value of y =2

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 3^4 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. It could be an integer, a fraction, a negative integer, or a decimal. Exponents are necessary since, without them, it is highly challenging to express the product when a number is repeated several times by itself. For instance, it is much simpler to write 5^7 than it is to write 5 5 5 5 5 5.

[tex]3^{x}-3^{y}=234\\ 3^{x-y}.3^{y}-3^{y}=234\\ 3^{y}(3^{x-y}-1)=234\\ 3^{y}(3^{x-y}-1)=3^{2}.26\\[/tex]

Step-by-step explanation:

You want to find the rational function (f/g)(x) and its value for x=1 when f(x) = 4x^4−19x^3−10x^2+35x−50 and g(x) = x-5.

The ratio function is the ratio of the given functions, found by dividing f(x) by g(x). Since g(x) is a binomial with a leading coefficient of 1, synthetic division is recommended. The attachment shows the result.

  [tex](f/g)(x)=\dfrac{f(x)}{g(x)}=\dfrac{4x^4-19x^3-10x^2+35x-50}{x-5}\\\\\boxed{(f/g)(x)=4x^3+x^2-5x+10}[/tex]

What is point-slop equation of a line?

The point-slope equation of a line is

The equation is useful when we know:

and want to find other points on the line.

Given that,

An equation of a line given the slope and a point is

             y - [tex]y_{1}[/tex] = m ( x  -[tex]x_{1}[/tex] )

or          y - 9 =  [tex]\frac{2}{3}[/tex] (x - 0)

or          y - 9 =  [tex]\frac{2}{3}[/tex] x

or          y =  [tex]\frac{2}{3}[/tex] x + 9

Answer: f(-7)=-9

Step-by-step explanation:

Answer:

y = -3/2x +11

Step-by-step explanation:

First you have to change the equation from standard form to slope form.

y = mx + b

2x-3y=7 --> subtract 2x from both sides

-3y = -2x + 7 --> now divide both sides by -3 to get y by itself

y = 2/3x - 7/3  --> the reason 2/3x is positive is because when there are two negatives it turns to a positive.

now you have to use point slope form y - y1 = m (x - x1)

x1 and y1 would be your point. 2 is x1 and 8 is y1

y - 8 = -3/2 (x - 2) --> the reason that m is -3/2 is because a perpendicular equation is the opposite reciprocal of the original slope

next distribute the -3/2

y-8 = -3/2x + 3 --> and now add 8 to 3 to get why by it self

now you have y = -3/2x + 11
