None of the given points satisfy the inequality 2x - 3y < 1.

Step-by-step explanation:

To determine which points satisfy the inequality 2x - 3y < 1, we can substitute the coordinates of each point into the inequality and check if the inequality holds true.

Let's consider the given points:

Point A: (1, 0)

2(1) - 3(0) < 1

2 - 0 < 1

2 < 1 (False)

Point B: (-1, -1)

2(-1) - 3(-1) < 1

-2 + 3 < 1

1 < 1 (False)

Point C: (3, -2)

2(3) - 3(-2) < 1

6 + 6 < 1

12 < 1 (False)

None of the given points satisfy the inequality 2x - 3y < 1.

Therefore, none of the points A, B, or C satisfy the inequality.

The equation for the absolute value function is y = -2lx-4l + 2

An absolute value function is what?

A function that surrounds an algebraic expression in absolute value symbols is called as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value. The definition of the absolute value parent function is given as follows: f(x)=x if x>00 if x=0 if x0.

Y=a| x+h |+k is the form of the equation for an absolute value function. Also:

The graph's vertex is (h,k).

The range of the graph is y≥k for a>0 and its domain is a set of all real numbers.

The range of the graph is y≤k when a0, and its domain is a set of all real numbers.

X=h is the symmetry axis.

If a>0, it opens up; if a0, it opens down.

The graph of y=a| xh |+k can be created by translating the line graph y=| x | by h units horizontally and k units vertically.

If | a | 1 and if | a | >1, the graph of y=a| x | is wider than the graph of y=| x | and narrower.

So here (h,k)=(4,2)
range of y≤2

and its narrower so a≥1
hence the equation is y = -2 l x-4 l +2

The 1,900 square feet rectangular area and the dimension of x that is a portion of the 190 feet side of the building gives the function and domain  for the length of fencing as follows;

(a) The formula for L in terms of x and y is L(x, y) = x + 2·y

(b) The formula that expresses the length of fencing, L as a function of x alone is presented as follows;

\(L(x) = \dfrac{x^2+3800}{x}\)

(c) The domain of L(x) is; (0, 190)

A function is a rule or law that gives the value of one variable (the output variable) as a function of another variable (the input variable).

The given parameter are;

The area of the enclosure = 1,900 ft²

The length of the side of the building adjacent to the enclosure = 190 ft

The fourth side of the enclosure = A portion of the 190 ft side of the building

The dimension of the enclosure = x and y

The length of the fencing = L

(a) The formula for the length of the fencing, L, in terms of x and y is found as follows;

The number of sides of the fencing = 3 (2 sides of length y and one side of length x)

The length of the fencing in terms of x and y is therefore;

L(x, y) = 2·y + x

(b) The shape of the enclosure = A rectangle

The area of a rectangle = Length × Width

Taking the length of the enclosure as the side y and the width of the enclosure as the side x, gives;

The area of the enclosure, A = 1,900 = x × y

\(\therefore y = \dfrac{1900}{x}\)

The length of the enclosure in terms of x alone, obtained by plugging in the value of y above, is therefore;

\(L(x) =2\cdot y + x = 2\cdot \left(\dfrac{1900}{x} \right)+ x = \dfrac{x^2+3800}{x}\)

(c) The domain of the function L(x) is found as follows;

Given that a portion of the side of the building that is 190 feet long is used as the fourth side and x is the dimension of the side of the rectangular enclosure parallel to the building, therefore; x < 190

From the function for L(x), x ≠ 0, therefore, x > 0

That is a question about properties of rhombus.

There is a property of a rhombus that says that the its diagonals divided the internal angles in two equals angles.

Now that we know about it, it is easier to solve this question, because now we know that \(2x+39\) and \(6x - 9\) are equal angles. So, we can make a equation and solve it:

\(2x+39 = 6x - 9\\39 + 9 = 6x - 2x\\48 = 4x\\4x = 48\\x=\frac{48}{4} \\x=12\)

Step-by-step explanation:

Explanation:

To get from  

5% to 100% you multiply by 20, so multiply the number in this case 39 by 20 percent.

39 is 5 percent of 780.

Given that we need to find 39 is 5% of what number,

To find the number that 39 is 5% of, we can use the concept of proportions.

Let's assume the number we're looking for is represented by "x." We can set up the proportion:

39 is 5% of x

Mathematically, this can be written as:

39 = 0.05x

To solve for x, we divide both sides of the equation by 0.05:

39 / 0.05 = x

The result is:

x = 780

Therefore, 39 is 5% of 780.

The given statement, "In a contingency table, when all the expected frequencies equal the observed frequencies the calculated statistic equals zero" is true because when all the expected frequencies equal the observed frequencies, the calculated statistic equals zero.

A contingency table is a table used in statistics that shows the distribution of one variable in rows and another variable in columns. It is also known as a cross-tabulation table or a two-way frequency table. In a contingency table, expected frequencies are calculated based on the assumption that there is no association between the variables being analyzed.

Observed frequencies, on the other hand, are the actual frequencies of the data being analyzed. When all the expected frequencies in a contingency table are equal to the observed frequencies, it means that there is no association between the variables, and the calculated statistic equals zero. This is because the difference between the observed and expected frequencies is used to calculate the statistic, and if there is no difference, the statistic will be zero.

Therefore, the statement "In a contingency table, when all the expected frequencies equal the observed frequencies the calculated statistic equals zero" is true.

There are 112 seats in row 22 of the auditorium, considering the pattern where each row has 2 more seats than the previous row.

Given that the first row contains 70 seats, we can determine the number of seats in row 22 by applying the pattern. Since each subsequent row has 2 more seats than the previous row, we can calculate the number of additional seats from the first row to the 22nd row.

The additional seats in row 22 can be calculated as (22 - 1) 2 = 42. This is because there are 21 rows between the first row and the 22nd row, and each row adds 2 seats.

To find the total number of seats in row 22, we add the additional seats to the seats in the first row:

Number of seats in row 22 = 70 + 42 = 112

The first term of the infinite geometric series is 625.Let's dive deeper into the explanation.

We are given that the sum of the infinite geometric series is \(\( \frac{15625}{24} \)\)and the common ratio is\(\( \frac{1}{25} \).\)The formula for the sum of an infinite geometric series is \(\( S = \frac{a}{1 - r} \)\), where \( a \) is the first term and \( r \) is the common ratio.
Substituting the given values into the formula, we have \(\( \frac{15625}{24} = \frac{a}{1 - \frac{1}{25}} \).\)To find the value of \( a \), we need to isolate it on one side of the equation.
To do this, we can simplify the denominator on the right-hand side.\(\( 1 - \frac{1}{25} = \frac{25}{25} - \frac{1}{25} = \frac{24}{25} \).\)
Now, we have \(\( \frac{15625}{24} = \frac{a}{\frac{24}{25}} \).\) To divide by a fraction, we multiply by its reciprocal. So, we can rewrite the equation as \( \frac{15625}{24} \times\(\frac{25}{24} = a \).\)
Simplifying the right-hand side of the equation, we get \(\( \frac{625}{1} = a \).\)Therefore, the first term of the infinite geometric series is 625.
In conclusion, the first term of the given infinite geometric series is 625, which corresponds to option (a).

Step-by-step explanation:

Given \(a\), half the length of the major axis, and \(b\), half the length of the minor axis for an ellipse, its eccentricity is \(\displaystyle e=\sqrt{1-\frac{b^2}{a^2}}\), which tells us how close the ellipse is to the shape of a circle or how flat and round it is. An infinitely long ellipse would have an infinitely long major axis, so the greater the \(a\) value, the eccentricity gets infinitely closer to 1.

The gradient of the function f(x, y) = √(x² + y² is (∂f/∂x, ∂f/∂y) = (x / √(x² + y²), y / √(x² + y²)).

To find the gradient of the function f(x, y) = √(x² + y²), we need to calculate the partial derivatives with respect to x and y. Taking the partial derivative with respect to x, we use the chain rule to obtain (∂f/∂x) = x / √(x² + y²). Similarly, taking the partial derivative with respect to y, we have (∂f/∂y) = y / √(x² + y²).

The gradient represents the rate of change of the function in each direction. In this case, it gives us the direction and magnitude of the steepest ascent of the function at each point. The magnitude of the gradient vector (∂f/∂x, ∂f/∂y) is the rate of change of the function in that direction.

Therefore, the gradient of f(x, y) = √(x² + y²) is (∂f/∂x, ∂f/∂y) = (x / √(x² + y²), y / √(x² + y²)), representing the direction and magnitude of the steepest ascent of the function.
