How do positive and negative numbers help us to represent mathematical ideas?

The power of quotients will be the law that would be used to simplify the expression. The correct option is B.

It should be noted that this is a mathematical rule that states that the power of a quotient is the same thing as the quotient that is gotten.

Given that the numerator p and the denominator q are raised to to the power expressed in the question separately.

The division will be:

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.

In conclusion, an equation which is the best model for a line of fit for the data is y = 3/4x + 5.

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

The area of the aerial banner which is to fly over a professional football game is 201600square inches and can be written as 2.06 ×[tex]10^{5}[/tex] square inches.

The length of the banner is given as 2× 103 inches which are 206 inches

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

The system of equations that could be used to determine the number of pounds of apples sold and the number of pounds of strawberries sold will be x + y = 35 and 2x + 3y = 80.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, each pound of apples sells for $2 and each pound of strawberries sells for $3. Aiden made $80 from selling a total of 35 pounds of apples and strawberries.

Suppose the number of pounds of apples and strawberries is x and y respectively.

If the total of 35 pounds of apples and strawberries as a result,

x + y = 35-------(1)

If each pound of apples sells for $2 and each pound of strawberries sells for $3. Aiden made $80 then,

2x + 3y = 80---------(2)

Multiply equation 1 by 2 and subtract from equation 2 as

2x + 3y -2(x+y) = 80 - 2(35)

y = 10

Substitute the value of y we get x = 25

As a result, there are 25 pounds of apples and 10 pounds of strawberries in all.

Thus, the system of equations that could be used to determine the number of pounds of apples sold and the number of pounds of strawberries sold will be x + y = 35 and 2x + 3y = 80.

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 + ....]
