How to work out (-4,-7),(7,5)

Answer:

47

Step-by-step explanation:

The equation that models the relationship is a(n) = 46-n( 4-1)

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Find the slope of the line;

m =( y2-y1)/x2-x1

= 6-5 /26-30

= 1/-4 = -1/4

the equation of a line is given as;

y-y1 = m ( x- x1)

= y-5 = -1/4(x-30)

= y -20 = -x +30

y = -x+50

y is the time and x is temperature

therefore the model that describe the relationship is ; a(n) = 46-n( 4-1), where a(n) is y and n is x.

Step-by-step explanation:

Answer:

So when we triple the value of "x" in that expression we also triple the value of "y". The corrrect answer is "x 3".

Step-by-step explanation:

For a given "x", y follows the expression: \(y = 8*x\). We have a new input to the function, which we will call "a", we know that this value is 3 times the value of the prior "x", so we can calculate what will happen to "y" as shown below:

\(y_1 = 8*x\)

For when the input is "a":

\(y_2 = 8*a\)

We know that "a" is 3 times x, therefore:

\(y_2 = 8*(3*x)\)

Due to the associative property of the product we can rewrite the above expression as:

\(y_2 = 3*(8*x)\)

Since "8*x" is the same as the prior "y", then we have:

\(y_2 = 3*y_1\)

So when we triple the value of "x" in that expression we also triple the value of "y". The corrrect answer is "x 3".

There are 625 possible combinations.

According to the multiplication principle, if an event A can happen in x different ways and an event B can happen in y different ways, then there are x y possibilities for both events to happen at once.

To determine the number of combinations possible with 4 cards and a spinner with 5 numbers, we can use the concept of the multiplication principle.

For the spinner, we have 5 possible numbers that can be selected.

For the 4 cards, each card can have any one of the 5 possible numbers from the spinner.

Using the multiplication principle, we multiply the number of choices for each item together to find the total number of combinations.

Number of combinations = Number of choices for the spinner × Number of choices for each card

                       = 5 × 5 × 5 × 5

                       = 625

Therefore, there are 625 possible combinations.

The solution of the expression is,

⇒ S = - 5100

Since, An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

We have to given that;

Sequence is,

⇒ ∑ n = 1 to n = 4 [ 100 (- 4)ⁿ⁻¹ ]

Now, We get;

⇒ a (n) = [ 100 (- 4)ⁿ⁻¹ ]

Replace n to n + 1;

⇒ a (n + 1) = 100 (- 4)ⁿ

And, For n = 1;

⇒ a (n) = [ 100 (- 4)ⁿ⁻¹ ]

⇒ a (1) = [ 100 (- 4)¹⁻¹ ]

⇒ a (1) =  100

And, Common ratio = - 4

Hence, The sum of geometric ratio is,

⇒ S = 100 (1 - (- 4)⁴) / (1 + 4)

⇒ S = 100 (1 - 256) / 5

The drop in the price of peanut butter would result in an increase in the demand for bread. In other words, the decrease in the price of peanut butter would result in an increase in the demand for bread.

Complementary goods are items that are frequently consumed together. As a result, when the cost of one of them changes, it affects the consumption of the other. When bread and peanut butter are complementary goods, a price reduction of peanut butter results in an increase in its demand. The demand for bread will increase as a result of the decrease in the price of peanut butter. As a result, if the price of peanut butter is reduced, its consumption will rise. As a result, the demand for bread would increase because of the complementary relationship between the two. Bread and peanut butter are complementary goods that are frequently purchased together.

When the price of peanut butter decreases, people would buy more peanut butter, causing them to purchase more bread to go with it. The drop in the price of peanut butter would result in an increase in the demand for bread. In other words, the decrease in the price of peanut butter would result in an increase in the demand for bread. The relationship between complementary goods is, therefore, inverse.

What is the graphic representation?

A graphic representation, in general, refers to any visual or graphical depiction of data, information, or concepts. It is a visual tool used to present information in a concise and easily understandable format. Graphic representations can take various forms, including charts, graphs, diagrams, maps, tables, and illustrations.

A bar graph is a type of chart that uses rectangular bars to represent data.

It is commonly used to display and compare categorical data or data that can be grouped into distinct categories.

In a bar graph, each category is represented by a bar, and the length or height of the bar corresponds to the value or frequency of that category.

In the context of the given question, the graphic is representing the ideal family size (total children) based on a survey of adults from a certain country.

The bar graph would likely have different bars representing different family sizes or categories (e.g., 0 children, 1 child, 2 children, etc.).

The length or height of each bar would indicate the percentage or frequency of respondents who considered that particular family size as ideal.

Compared to a dot plot, which represents individual data points with dots, and a pie chart, which displays the proportions of a whole using slices of a circle, the description provided suggests that the graphic is a bar graph since it uses bars to represent data categories.

Answer:

x = 10, y = 20

Step-by-step explanation:

Because two sides of the rightmost triangle are congruent, the base angles would follow suit. This means 5x - 10 = 3x + 10. Simplifying this we get:

2x = 20

x = 10

Next, in the other triangle, we can say the same thing, the base angles would be congruent. From this we can say that the other base angle is 4y. Using the exterior angle theorem, we can say that the two angles with x terms add to 4y. This means 3x + 10 + 5x - 10 is 4y. We already know x is 10, so substituting that in we get:

80 = 4y

y = 20

The observation is located to the left of the mean by a distance of 1.2 standard deviations.

The z-score of an observation represents the number of standard deviations the observation is away from the mean.

If the z-score for a particular observation is z = -1.2, this means that the observation is 1.2 standard deviations below the mean.

If the mean is represented by μ and the standard deviation by σ, then we can express this observation as:

observation = μ + (z * σ)

observation = μ + (-1.2 * σ)

This means that the observation is located to the left of the mean by a distance of 1.2 standard deviations.

For example, The z-score represents the number of standard deviations an observation is above or below the mean of the distribution.

In this case, a z-score of -1.2 indicates that the observation is 1.2 standard deviations below the mean height of the group.

the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].

To find the derivative of the function y = (ln(x + 4))x using logarithmic differentiation, we can follow these steps:

Step 1: Take the natural logarithm of both sides of the equation:

  ln(y) = ln((ln(x + 4))x)

Step 2: Use the logarithmic property ln(a^b) = b ln(a) to simplify the right-hand side of the equation:

  ln(y) = x ln(ln(x + 4))

Step 3: Differentiate both sides of the equation implicitly with respect to x:

  (1/y) * y' = ln(ln(x + 4)) + x * (1/ln(x + 4)) * (1/(x + 4))

Step 4: Simplify the expression on the right-hand side:

  y' = y * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]

Step 5: Substitute the original expression of y = (ln(x + 4))x back into the equation:

  y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]

Therefore, the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].

The approximate coordinates for (x,y) on the unit circle, given an arc length of 2.7, are (x ≈ -0.605, y ≈ 0.796).

To find the approximate coordinates (x, y) on the unit circle, we can use the trigonometric functions cosine and sine. Given an arc length of 2.7, we substitute the value into the trigonometric functions.

Using a calculator, we find that cos(2.7) ≈ -0.605 and sin(2.7) ≈ 0.796.

Therefore, the approximate coordinates for the point (x, y) on the unit circle, starting at (1, 0) and terminating at the point (x, y) with an arc length of 2.7, are approximately (x ≈ -0.605, y ≈ 0.796).

These coordinates represent the x and y coordinates of a point on the unit circle that lies along the arc with a length of 2.7 units, starting from the point (1, 0) and ending at the point (x, y).
