Answer: y = [tex]\frac{1}{2}[/tex]x + 4

Step-by-step explanation:

       First, let us graph the points to see patterns. See attached.

     This function is linear, so we can write an equation in slope-intercept form. m is the slope and b is the intercept.

      We can find the slope with rise over run. Starting at point (0, 4) and counting up one and over 2 to (2, 5).

y = mx + b

y = [tex]\frac{1}{2}[/tex]x + 4

The distance between points A and B is 9.22units, approximately.

This is further explained below.

Generally, In the image attached, you can observe a representation of the problem.

We have to find the distance between points A and B, which have coordinates (7,0) and (0,6), respectively.

The definition of distance between two given points is

[tex]d=\sqrt{\left(y_2-y_1\right)^2+\left(x_2-x_1\right)^2}[/tex]

Using points A and B, the distance between us

[tex]&d_{A B}=\sqrt{(7-0)^2+(0-6)^2}\\\\d_{A B}=\sqrt{49+36}\\\\\ d_{A B}=\sqrt{85} \\\\&d_{A B} \approx 9.22[/tex]

In conclusion, the distance between points A and Ais 9.22 units, approximately.

An equation which is the best model for a line of fit for the given data is y = 3/4x + 5.

A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.

By critically observing the graph (see attachment) which models the data in the table above, we can logically deduce that an equation for the line of best fit is given by y = 3.7x + 0.3.

Step-by-step explanation: We divide the price of certain number of units of an item by the number of units to find the unit price of that item. For example, to find the unit price of 12 ounces of soup that costs $2.40, divide $2.40 by 12 ounces, to get unit price of soup as $0.20 per ounce.

Using logarithmic expansion, we get expansion for the function log₃(2x+1) is f(x) = {1/log (3)} [2x - 2² . x²/2 + 2³ . x³/3 -  2⁴. x⁴/4 + ....]

According to the question, we need to expand  log₃(2x+1) using logarithmic expansion,

Let f(x) =  log₃(2x+1)

Using change base rule →logₐ b = logₓ (b) / logₓ (a), x > 0. We get

⇒ log (2x+1) /log (3)      

= {1/log (3)} [log (1+2x)]         →(1)

Logarithmic expansion: log (1+x) = x - x²/2 + x³/3 - x⁴/4.....∞

Replace '2x' in the place of 'x' in the above logarithmic expansion, we get

log (1+2x) = 2x - (2x)²/2 + (2x)³/3 - (2x)⁴/4.....∞     →(2)

Substitute (2) in equation (1), we get

f(x) = {1/log (3)} [2x - 2² . x²/2 + 2³ . x³/3 -  2⁴. x⁴/4 + ....]

Hence, using logarithmic expansion we get expansion for the function log₃(2x+1) is f(x) = {1/log (3)} [2x - 2² . x²/2 + 2³ . x³/3 -  2⁴. x⁴/4 + ....]

No we can not  expand the given logarithmic expression log₃(2x+1).

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

Answer:9-4=5  5+4=9

Step-by-step explanation:

The standard form for the linear equation is y=6a+38.

An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=5x+3. Where:

a= the slope.

b= the constant term that represents the y-intercept.

For the given example: a=5 and b=3.

The question gives:

- the value of the slope (a) = 6

- the coordinates of a point = (-3,20)

Thus, you can write from the question information :

y=ax+b

20=6*(-3)+b

20=-18+b

b=20+18=38

Therefore, the standard form for the linear equation is:

The expected number of balls in the first bin would be (1/n)^n

It is given that,

The number of balls and bins is same

If so, then there should always be one ball in each container. The likelihood that every ball will land in the first bin is (1/n)^n.

For example -

Let there be three balls and three bins. Put an A, B, and C next to each ball. The bins are marked 1, 2, and 3. Ball A is likely to land in bin 1 with a 1/3 chance. However, there is a 1/3 chance that ball B will land in bin 1, and there is a 1/3 chance that ball C will land in bin 1. As a result, bin 1 should have a value of 1/3 + 1/3 + 1/3 = 1. The expected values of bins 2 and 3 follow a similar rationale.

By the same reasoning, bins 2 and 3 should likewise have anticipated values of 1.

How likely is it that all three balls will fall into bin one?

1/3 x 1/3 x 1/3 = 1/27, or in the general situation, (1/n)^n, which equals (1/3)^3.

Hence, the expected number of balls in the first bin would be (1/n)^n

given that the function is y=6-x.

A function that can reverse into another function is known as an inverse function or anti function. A function takes in values, applies specific operations to them, and produces an output. In order to find y when x is swapped with another variable, we must first determine the inverse function.

The equation of the parabola is y = (x + 3)^2 - 1

Parabolic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The given parameters are

Vertex = (-3, -1)

X-intercept = (-4, 0)

A parabolic equation has the form y = a(x - h)^2 + k

Where the vertex is (h, k)

This means that, (h, k) is given as

(h, k) = (-3, -1)

Substitute (h, k) = (-3, -1) in the equation y = a(x - h)^2 + k

So, we have

y = a(x + 3)^2 - 1

Next, we substitute (-4, 0) for (x, y) in y = a(x + 3)^2 - 1

So, we have

0 = a(-4 + 3)^2 - 1

This gives

0 = a - 1

Solve for a

a = 1

Substitute a = 1 in y = a(x + 3)^2 - 1

y = (x + 3)^2 - 1

So, the required equation of the parabola is y = (x + 3)^2 - 1

Hence, the equation of the parabola is y = (x + 3)^2 - 1
