As x approaches zero from the left, the expression 4 + x/3 + f(1/x) simplifies to 6. Therefore, the limit lim x → 0- [4 + x/3 + f(1/x)] exists, and its value is 6.

To determine the existence and value of the limit, we need to consider the behavior of the function f(x) as x approaches zero from the left (x → 0-).

Given that lim x → -∞ f(x) = 2, we know that as x approaches negative infinity, f(x) approaches 2. Similarly, from lim x → ∞ f(x) = 4, we can conclude that as x approaches positive infinity, f(x) approaches 4.

Now, let's consider the expression 4 + x/3 + f(1/x). As x approaches zero from the left (x → 0-), the term 4 + x/3 remains constant, and the term f(1/x) becomes f(1/0-) (since 1/x approaches negative infinity).

Since f(x) approaches 2 as x → -∞, we can substitute f(1/x) with 2 in the expression. Thus, the expression becomes 4 + x/3 + 2.

Now, as x approaches zero from the left (x → 0-), the term x/3 approaches 0, while the constant terms 4 and 2 remain unchanged. Therefore, the expression 4 + x/3 + 2 becomes 6.

Answer:

fraction way would be

Step-by-step explanation:

Answer:

\(\large\boxed{y=-\frac{3}{2}x+\frac{3}{2}}\)

Step-by-step explanation:

Use the two-points slope equation: \(\boxed{m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}}\)

Given the two coordinate points of \((x_{1}, y_{1})\) and \((x_{2}, y_{2})\), implement these values into the equation and solve for m.

\(m=\frac{(3)-(6)}{(-1)-(-3)}\\\\m=\frac{(-3)}{(2)}\\\\m=-\frac{3}{2}\)

The slope is then placed in the equation - y = -3/2x + b.

Then, insert a value for y and x from the same coordinate point to solve for b.

\(6=-\frac{3}{2}(-3)+b\\\\6=\frac{9}{2}+b\\\\\frac{3}{2}=b\)

Then, plug it all in to get \(\large\boxed{y=-\frac{3}{2}x+\frac{3}{2}}\).

Answer:

y=-3/2x  

Step-by-step explanation:

First, find the slope with y2-y1/x2-x1=m

3-6                      m=-3/2

--------- =

-1-+-3

Now plug it in to point slope form

Point slope form is y-y1=m(x-x1)

y-3=-3/2(x--1)       Distribute -3/2 to x and 1

y-3=-3/2x-3         Add three on both sides to get y alone

y=-3/2x                Three's cancel out. This is the final equation.

The rectangle with dimensions 21 m by 21 m has the largest area among rectangles with a perimeter of 84 m.

To find the dimensions of a rectangle with a perimeter of 84 m that maximizes the area, we need to use the properties of rectangles.

Let's assume the length of the rectangle is l and the width is w.

The perimeter of a rectangle is given by the formula: 2l + 2w = P, where P is the perimeter.

In this case, the perimeter is given as 84 m, so we can write the equation as: 2l + 2w = 84.

To maximize the area, we need to find the dimensions that satisfy this equation and give the largest possible value for the area. The area of a rectangle is given by the formula: A = lw.

Now we can solve the perimeter equation for l: 2l = 84 - 2w, which simplifies to l = 42 - w.

Substituting this expression for l into the area equation, we get: A = (42 - w)w.

To maximize the area, we can find the critical points by taking the derivative of the area equation with respect to w and setting it equal to zero:

dA/dw = 42 - 2w = 0.

Solving this equation, we find w = 21.

Substituting this value of w back into the equation l = 42 - w, we get l = 42 - 21 = 21.

Therefore, the dimensions of the rectangle that maximize the area are l = 21 m and w = 21 m.

In summary, the dimensions of the rectangle are 21 m by 21 m, so the answer is A. 21, 21.

Charlie strictly prefers the bundle (6, 16) to more than one of the given bundles.

The indifference curves of Charlie have the equation xB = constant/xA, where larger constants represent better indifference curves. In this case, the bundle (6, 16) corresponds to xA = 6 and xB = 16.

To determine if Charlie strictly prefers the bundle (6, 16) to the other given bundles, we compare the values of xB for each bundle while keeping xA constant.

a. For the bundle (16, 6), xB = 6/16 = 3/8.

b. For the bundle (7, 15), xB = 15/7.

c. For the bundle (10, 11), xB = 11/10.

Comparing these values, we can see that xB = 16 is greater than xB for all the other bundles. Therefore, Charlie strictly prefers the bundle (6, 16) to the bundles (16, 6), (7, 15), and (10, 11).

Hence, the correct answer is that Charlie strictly prefers the bundle (6, 16) to more than one of these bundles.

The uncertainties ⟨Δx^2⟩ and ⟨Δp^2⟩ are given by the expressions ⟨Δx^2⟩ = a^2/2 and ⟨Δp^2⟩ = (ℏ^2)/(8a^2).

To calculate the uncertainties ⟨Δx^2⟩ and ⟨Δp^2⟩ for the given wave packet, we need to find the expectation values of the observables (x^ - ⟨x⟩)^2 and (p^ - ⟨p⟩)^2, respectively.

The wave packet is represented by the function ψ(x) = [2πa^2]^(1/2) exp[-4a^2(x - ⟨x⟩)^2 + iℏpx]. Here, a is a constant, ⟨x⟩ represents the expectation value of x, and p is the momentum operator.

To find ⟨Δx^2⟩, we calculate the expectation value of (x^ - ⟨x⟩)^2 with respect to ψ(x). By integrating (x - ⟨x⟩)^2 multiplied by the squared magnitude of the wave packet over all x values, we obtain the result ⟨Δx^2⟩ = a^2/2.

Similarly, to find ⟨Δp^2⟩, we calculate the expectation value of (p^ - ⟨p⟩)^2 with respect to ψ(x). Since p is the momentum operator, its expectation value is ⟨p⟩ = 0 for the given wave packet. By integrating (p^ - 0)^2 multiplied by the squared magnitude of the wave packet over all x values, we obtain the result ⟨Δp^2⟩ = (ℏ^2)/(8a^2).

Therefore, the uncertainties ⟨Δx^2⟩ and ⟨Δp^2⟩ are given by the expressions ⟨Δx^2⟩ = a^2/2 and ⟨Δp^2⟩ = (ℏ^2)/(8a^2).

The solutions to the quadratic equation f(x) = x² + 10x - 1 are x = -5 + √26 and x = -5 - √26

To solve the quadratic equation f(x) = x² + 10x - 1

we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

For the given equation, a = 1, b = 10, and c = -1.

Substituting these values into the quadratic formula:

x = (-(10) ± √((10)² - 4(1)(-1))) / (2(1))

= (-10 ± √(100 + 4)) / 2

= (-10 ± √104) / 2

Simplifying further:

x = (-10 ± 2√26) / 2

= -5 ± √26

Therefore, the solutions to the quadratic equation f(x) = x² + 10x - 1 are:

By solving a system of equations, we will see that the rational function is:

\(f(x) = \frac{12}{(x + 2)} -3\)

First, we need to see the x-value of the vertical asymptote, here we can see that the vertical asymptote happens at x = -2, then the denominator will be something like:

d = (x - (-2)) = (x + 2).

Then our rational function will be something like:

\(f(x) = \frac{a}{(x + 2)} + c\)

In the graph we can see two things, first:

f(0) = 3

f(1) = 1

Replacing that in our function, we get:

\(\frac{a}{(0 + 2)} + c = 3\\\\ \frac{a}{(1 + 2)} + c = 1\)

This is a system of equations, that can be rewritten as:

a/2 + c = 3

a/3 + c = 1

Isolathing c in both equations, we get:

a/2 - 3 = -c = a/3 - 1

Then we have:

a/2 - 3 = a/3 - 1

Now we can solve this for a:

a/2 - a/3 = 3 - 1

a/6 = 2

a = 2*6 = 12

And the value of c is given by:

-c = a/3 - 1 = 12/3 - 1 = 4 - 1 = 3

c = -3

Step-by-step explanation:

The Pythagorean theorem is

a^2+b^2 = c^2  where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)

a^2 + b^2 = c^2

Substitute the known values

5^2 + b^2 = 13^2

25+b^2 = 169

Subtract 25 from each side

25+b^2-25 =169-25

b^2 = 144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b=12

Answer:

Given:

To find:

Answer:  The steps and answers to the first two are below but you need to understand slope  = change in y / change in x  = y2 - y1/ x2 - x1  

And you need to understand  y = mx + c  

m= slope   c is y intercept

Substitute either point given  - only use one as the x and y  and find c

Step-by-step explanation:

1.      You need to follow the steps -

          the point is given as  (2,5)  = (x,y)  

So what this means is  x =2 and y =5

Simple substitutions is the step  5   = 3 x 2 + c

                                                     5 = 6 + c  or easier to see is  c + 6 =5

subtract 6 from both sides   c +  6   =  5

                                                    -6      -6

                                           __________________

                                              c           =  -1

2.

 x1,y1           x2,y2

( 3,2)   and (5,6) are two points on the line  

you already calculate the slope which is   m = noy2-y1/x2-x1 = 6-2/5-3 = 4/2 = 2

Remember y= mx + c

                   y = 2 x + c

now substitute in (3,2) which is (x1, y1) into the x and y in your equation

                  2  = 2 (3)  + c

                  2 = 6 + c

 subtract 6 from both sides

                  -4 = c

Answer:

vertex = (3, - 8 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

\(x_{vertex}\) = - \(\frac{b}{2a}\)

y = x² - 6x + 1 ← is in standard form

with a = 1 and b = - 6 , thus

\(x_{vertex}\) = - \(\frac{-6}{2}\) = 3

Substitute x = 3 into the function for y

y = 3² - 6(3) + 1 = 9 - 18 + 1 = - 8

vertex = (3, - 8 )

The vector A can be determined by adding vector B to vector C element-wise. The resulting vector A is [3 6 -1 1 3 7 1 1 3].

To find vector A, we need to add vector B to vector C element-wise. Element-wise addition means adding corresponding elements of the vectors together. Given that B = [1 6 -1 2 6 1 -1 -2 4] and C = [2 0 0 -1 -3 6 2 3 -1], we can perform the addition as follows:

A = B + C = [1+2 6+0 -1+0 2+(-1) 6+(-3) 1+6 -1+2 -2+3 4+(-1)]

= [3 6 -1 1 3 7 1 1 3]

Thus, the resulting vector A is [3 6 -1 1 3 7 1 1 3].

The given statement "An algorithm is a calculation that determines how long it will take to solve a problem." is False.

An algorithm is not just a calculation that determines how long it will take to solve a problem. An algorithm is a step-by-step set of instructions or a process used to solve a problem or perform a specific task. It is a systematic approach that allows a computer or human to break down a problem into smaller, manageable parts and reach a solution effectively.

Algorithms are the foundation of computer programming and can be applied in various fields such as mathematics, data processing, and problem-solving. They can be simple, like finding the largest number in a list, or complex, like solving a Rubik's Cube.

Efficiency is a key factor in evaluating algorithms. The time and resources required for an algorithm to solve a problem can vary greatly depending on the method used. However, the primary purpose of an algorithm is to provide a clear and concise procedure to reach a solution, rather than just estimating the time needed to solve a problem.

In summary, an algorithm is a well-defined process designed to perform a specific task or solve a problem, rather than just calculating the time required to do so. Its effectiveness depends on its efficiency, accuracy, and the simplicity of the steps involved.

Probability of not selecting blue

First, we calculate the probability of selecting blue

\(P(Blue) = \frac{Blue}{Total}\)

\(P(Blue) = \frac{2}{2+2}\)

\(P(Blue) = \frac{2}{4}\)

\(P(Blue) = \frac{1}{2}\)

False. To calculate a percent increase, the portion is not the missing element. The portion refers to the initial or original value, while the missing element is the final or increased value.

The formula for calculating a percent increase is:

Percent Increase = (Final Value - Initial Value) / Initial Value * 100

In this formula, the initial value is the portion that represents the starting or original value. The final value is the missing element, as it represents the increased or final value after the increase.

By subtracting the initial value from the final value, we obtain the difference between the two. Dividing this difference by the initial value gives us the relative increase as a decimal or fraction. Multiplying by 100 converts it into a percentage, representing the percent increase.

In hypothesis testing, the critical value refers to the value of a test statistic that divides all possible values into an acceptance region and a rejection region.

The null hypothesis is a statement that assumes there is no significant difference between two or more variables. The probability, 1-alpha, represents the level of significance that is set before conducting a hypothesis test. This probability is used to determine the critical value, which is the point beyond which the null hypothesis will be rejected. The critical value is important because it helps to determine whether a sample result is statistically significant or not. By comparing the test statistic to the critical value, we can decide whether to reject or accept the null hypothesis.

The circle has diameter = 12 - 3 - 3 = 12 - 6 = 6 ft

then radius r = 6 ÷ 2 = 3 ft

area of circle = πr² = 3.14 × 3² = 3.14 × 9 = 28.26 ft²

Then

area of figure = 36 + 28.26 = 64.26 ft²
