How can I turn this equation into standard form

Answer:

[tex]y = 2x - 1[/tex]

Step-by-step explanation:

We can represent this line in an equation in slope-intercept form:

[tex]y = mx + b[/tex],

where [tex]m[/tex] is the line's slope (rise over run), and [tex]b[/tex] is the y-coordinate of its y-intercept.

First, we can solve for the line's slope:

slope = rise / run = 2/1 = 2

Next, we can identify the y-coordinate of the y-intercept by looking at the vertical axis' value when the red line crosses it:

-1

Finally, we can put these two pieces of information together to form an equation in slope-intercept form:

[tex]\boxed{y = 2x - 1}[/tex]

If the area of a kite is 35cm square, the area of the new kite with all diagonals multiplied by 2 is 70 cm².

If we multiply all the diagonals of a kite by 2, then the area of the new kite will be 4 times the area of the original kite.

The area of a kite is given by the formula:

Area = (diagonal 1 x diagonal 2)/2

Let the diagonals of the original kite be d1 and d2. Then, the area of the original kite can be expressed as:

Area = (d1 x d2)/2 = 35 cm²

If we multiply all the diagonals of the original kite by 2, then the new diagonals will be 2d1 and 2d2. The area of the new kite can be expressed as:

New area = (2d1 x 2d2)/2 = 2d1d2

Substituting the value of d1d2 from the original equation, we get:

New area = 2d1d2 = 2 x (d1 x d2) = 2 x Area = 2 x 35 cm² = 70 cm²

The function f is onto.

To determine if the function f is one-to-one, we need to check if each element in the domain maps to a unique element in the range. Looking at the function, we can see that f(a) = 1, f(b) = 2, f(c) = 3, and f(d) = 3. Since two elements in the domain (c and d) map to the same element in the range (3), the function f is not one-to-one.

To determine if the function f is onto, we need to check if every element in the range is mapped to by at least one element in the domain. Looking at the function, we can see that all four elements in the range (1, 2, 3, and 4) are mapped to by at least one element in the domain. Therefore, the function f is onto.

The slope of the rope is 0.25 with the respective situation as the rope is attached to 6-foot high wall and the horizontal distance is 24 feet.

We need to determine the ratio of the vertical change to the horizontal change to establish the slope of the rope's line. To begin, we may use the Pythagorean theorem to calculate the length of the rope:

a² + b² = c²

where an is the height of the wall, b is the horizontal distance from the wall to the point where the rope is tied to the ground, and c is the length of the rope.

When we solve for c, we get:

c = √(6² + 24²)

c = √(36 + 576)

c = √612

c = around 24.73 feet

Consider a right triangle created by the wall, the point where the rope is fastened to the ground, and a point on the rope directly above the wall's top.

The vertical change is the wall's height, which is 6 feet.

The horizontal change is the distance of 24 feet between the place where the rope is tied to the ground and the wall.

As a result, the slope of the rope-representing line is:

vertical change / horizontal change = slope

slope = 6 / 24

slope = 0.25

Answer: This situation involves choosing a group of 5 players out of a total of 12 players, where the order in which the players are chosen does not matter. Therefore, this is an example of a combination problem.

The number of ways to choose a group of 5 players out of 12 is given by the formula for combinations:

n C r = n! / (r! * (n-r)!)

where n is the total number of players, r is the number of players being chosen, and "!" represents the factorial operation.

In this case, we have n = 12 and r = 5, so the number of different choices of starters is:

12 C 5 = 12! / (5! * (12-5)!)

= 792

Therefore, there are 792 different choices of starters that the coach can make from the team of 12 players.

what is Pythagorean theorem  ?

The Pythagorean theorem is a mathematical concept that describes the relationship between the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In the given question,

We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the tower, the guy wires, and the ground form a right triangle. Let's call the length of the guy wires "x". Then we can set up the following equation:

x² = 840² + (130)²

Simplifying and solving for x, we get:

x² = 705600 + 16900

Fred should use a critical value of 2.145 and a standard error of the mean of 2.84 to construct a 95% confidence interval for the average length of movies he watches

To construct a confidence interval for the population mean length of movies watched by Fred, we can use the following formula

Confidence interval = sample mean +/- (critical value) x (standard error)

where the standard error of the mean (SE) is calculated as:

SE = sample standard deviation / sqrt(sample size)

Since Fred's sample size is 15 and he wants a 95% confidence interval, we need to find the critical value for a t-distribution with 14 degrees of freedom (n-1), which can be obtained from a t-distribution table or calculator.

Using a t-distribution calculator with 14 degrees of freedom and a 95% confidence level, we find the critical value to be 2.145.

The given point [tex]s C(2, -8), D(-6, 4),[/tex] and [tex]E(0, 4)[/tex] form the triangle △CDE, and the points U(1, -4), V(-3, 2), and W(0, 2) form the triangle △UVW, with △CDE being the preimage of △UVW.

To represent the transformation algebraically, we can use a combination of translations and rotations.

Translation:

To translate a point (x, y) by a vector (h, k), we add h to the x-coordinate and k to the y-coordinate of the point.

To transform triangle △CDE to triangle △UVW, we can first translate triangle △CDE by a vector (h, k) to obtain triangle △C'D'E', where C' = C + (h, k), D' = D + (h, k), and E' = E + (h, k).

Since the coordinates of C are (2, -8) and the coordinates of U are (1, -4), we can calculate the translation vector (h, k) as follows:

[tex]h = 1 - 2 = -1[/tex]

[tex]k = -4 - (-8) = 4[/tex]

So the translation vector is [tex](-1, 4).[/tex]

Rotation:

To rotate a point (x, y) by an angle θ counterclockwise about the origin, we use the following formulas:

[tex]x' = x \times \cos(\theta) - y times \sin(\theta)[/tex]

[tex]y' = x \times \sin(\theta) + y \times \cos(\theta)[/tex]

To transform triangle △C'D'E' to triangle △UVW, we can apply a rotation of angle θ counterclockwise about the origin to triangle △C'D'E', where C' = (x1', y1'), D' = (x2', y2'), and E' = (x3', y3'). Since the coordinates of C' are (2, -8) after translation, and the coordinates of U are (1, -4), we can calculate the rotation angle θ as follows:

[tex]\theta = atan2(y1' - y2', x1' - x2') - atan2(y1 - y2, x1 - x2)= atan2((-8 + 4) - (-4), (2 + 1) - (-6 + 3)) - atan2((-8) - (-4), 2 - (-6))[/tex]

Using a calculator, we can find θ to be approximately -0.785 radians.

So, the algebraic representation of the transformation that maps triangle [tex]\triangle CDE[/tex] to triangle [tex]\triangle UVW[/tex]  is:

Translate triangle △CDE by the vector (-1, 4) to obtain triangle △C'D'E':

[tex]C' = (2, -8) + (-1, 4) = (1, -4)[/tex]

[tex]D' = (-6, 4) + (-1, 4) = (-7, 8)[/tex]

[tex]E' = (0, 4) + (-1, 4) = (-1, 8)[/tex]

Therefore, Rotate triangle △C'D'E' counterclockwise by approximately -0.785 radians about the origin:

[tex]x1' = 1 \times cos(-0.785) - (-4) \times sin(-0.785) \approx 0.436[/tex]

[tex]y1' = 1 \times sin(-0.785) + (-4) \times cos(-0.785) \approx -3.678[/tex]

∠1 = 118°

Now, opposite angles are congruent and ∠2 is an opposite angle to 62°. Thus: ∠2 = 62°.

Similarly: ∠3 = 118° because it is congruent to ∠1

Alternate angles are congruent and ∠5 is an alternate angle to 32°. Thus:

Therefore, the conclusion we can draw is: Together, Streetcar and Cable Car are the preferred transportation for 168 residents.

We cannot conclude that Walk and Streetcar are the preferred transportation for 55 residents, as there is no overlap between the sections representing these modes of transportation on the circle graph.

We cannot conclude that Bus is the preferred transportation for 45 residents, as the Bus section represents only 10% of the total sample size, which corresponds to 0.10 x 400 = 40 residents.

We cannot conclude that Bicycle is the preferred transportation for 50 residents, as the Bicycle section represents only 8% of the total sample size, which corresponds to 0.08 x 400 = 32 residents.

a. The most typical case is desired: Mode. The mode is a useful measure of central tendency when the most typical or common value is of relevance since it denotes the value or category that occurs most frequently in a data collection.

b. The distribution is open-ended: Median. The median is the middle value in a data set when arranged in ascending or descending order. It is a suitable measure of central tendency when the distribution is open-ended or skewed, as it is less affected by extreme values compared to the mean.

c. The data collection has an extreme value: the median. The median is less sensitive to extreme values compared to the mean, making it a better measure of central tendency in data sets with extreme values or outliers.

d. The data are categorical: Mode. The mode is appropriate for categorical data, as it represents the most frequently occurring category or value in the data set.

e. Further statistical computations will be needed: This statement does not indicate a specific measure of central tendency. Further statistical computations may be needed to determine the appropriate measure of central tendency depending on the characteristics of the data and the specific objectives of the analysis.

f. The numbers should be split into two roughly equal groups, one of which should contain the higher values and the other should contain the smaller values: Median.  The median is the value that separates a data set into two equal halves, making it suitable for dividing data into two approximately equal groups based on their values.

The number line that shows the number of miles where A is less expensive has a solution of x > 60

From the question, we have the following parameters that can be used in our computation:

Option    Daily Cost ($) Cost per mile ($)

   A               25                   0.15  

   B                10                    0.40

So, the cost functions are

A = 25 + 0.15x

B = 10 + 0.4x

Where x is the number of miles

When A is less expensive, we have

25 + 0.15x < 10 + 0.4x

Evaluate the like terms

15 < 0.25x

So, we have

0.25x > 15

Divide

x > 15/0.25

Evaluate

x > 60

Hence, the number line is (a)

The number of terms in the expansion of the expression[tex][(3x^2y)^2(3x-2y)^2]^3[/tex] after it is simplified to lowest terms is the product of the number of terms in the base and the number of terms in the exponent,

which is:

[tex]1 \times 7 = \boxed{7}[/tex]

The expression [tex][(3x^2y)^2(3x-2y)^2]^3[/tex]by using the laws of exponents and expanding the products of powers.

First, we can simplify the term inside the square brackets:

[tex](3x^2y)^2(3x-2y)^2 = 9x^4y^2 (3x-2y)^2[/tex]

Expanding the square of [tex](3x-2y)^2[/tex] gives:

[tex](3x-2y)^2 = (3x)^2 - 2(3x)(2y) + (2y)^2 = 9x^2 - 12xy + 4y^2[/tex]

Substituting this back into the expression gives:

[tex]$[(3x^2y)^2(3x-2y)^2]^3 = (9x^4y^2)(9x^2 - 12xy + 4y^2)^2]^3[/tex]

Expanding the cube of the expression gives:

[tex]$[(9x^4y^2)(9x^2 - 12xy + 4y^2)^2]^3 = (9x^4y^2)^3(9x^2 - 12xy + 4y^2)^6$[/tex]

The expression has only one term, which is the product of two terms raised to a power.

To determine the number of terms in the expansion, we need to expand the binomial. [tex](9x^2 - 12xy + 4y^2)^6[/tex]

Using the binomial theorem,

The expansion will have 7 terms, since the exponents on [tex]9x^2, -12xy, and 4y^2[/tex]will range from 6 to 0, and the sum of the exponents will always be 6.
