Find the limit of the function algebraically. limit as x approaches zero of quantity negative six plus x divided by x to the fourth power.

Answers

Final answer:

The limit as x approaches zero of the function (-6 + x)/x^4 is 0. This is arrived at using L'Hopital's Rule, which instructs us to take the limits of the derivatives of the numerator and denominator when the initial function limit causes an indeterminate form (0/0, infinity/infinity).

Explanation:

The limit of the function negative six plus x divided by x to the fourth power as x approaches zero cannot be solved using traditional limit computations as it creates indeterminate form. However, the L'Hôpital's rule

Rule can be used to determine this limit.

Under L'Hôpital's rule

rule, to solve for the limit of a function that results in an indeterminate form 0/0 or infinity/infinity, you take the derivative of the numerator and the derivative of the denominator independently, and then find the limit of that quotient as x approaches the given value.

In this case, the function is (-6+x)/x4. The derivative of -6+x is 1 and the derivative of x4 is 4x3. Therefore, after the first iteration of L'Hopital's rule, you are finding the limit as x approaches zero of 1/(4x3). Running the rule again we get 0/(12x2). Clearly there, the numerator is 0 and since x2 will be a non-negative number the limit would be 0. Hence, the limit of the function as x approaches zero is 0.

Which is the correct label of the parallel lines? parallel lines a and b are shown. points a and b lie on line a while points c and d lie on line
b?

Answers

Final answer:

The parallel lines mentioned in the question are correctly labeled as 'AB' for Line a (which involves points A and B) and 'CD' for Line b (which refers to points C and D).

Explanation:

In geometry, parallel lines are often labeled with the same letter. In your case, the parallel lines are described as Line a and Line b. Points A and B lie on Line a, and Points C and D lie on Line b. Therefore, to correctly label the lines, 'Line a' is written as 'AB' since points A and B are on this line. Meanwhile, 'Line b' is labeled as 'CD' since points C and D are on that line.

So, in conclusion, the correct labels for the mentioned parallel lines are AB for 'Line a' and CD for 'Line b'.

Which of the following products represents 6 1/2% tax, in dollars, on a price of $14.29? a. (0.00675)(14.29) b. (0.0675)(14.29) c. (0.675)(14.29) d. (6.75)(14.29)

Answers

to Convert a percentage to a decimal, you divide the percentage number by 100.
6.5% ÷ 100 = .065.
This is the rate you will multiply $14.29 by to get the amount of sales tax you must pay.

The correct answer is (0.065) (14.29) = $0.93

Based on the information provided, none of the above options are correct.

Mark has a container in the shape of a cube. He uses 64 cubes with side lengths of 1 inch to completely fill the container. What is the edge length of the container?

Answers

This means the area is 64 inches^2:

x * x = 64
x = 8

Hope this helps!

Answer:

4 inches is the edge length of the container.

Step-by-step explanation:

Length of the small cubes = a = 1 inch

Volume occupied each small cube = v = [tex]a^3=(1 inch )^3= 1 inches^3[/tex]

Length of the big cube = A

Volume of the big cube = V

[tex]V=A^3[/tex]

He uses 64 cubes with side lengths of 1 inch to completely fill the container.

[tex]V=64\times v=64\times 1 inches^3[/tex]

[tex]A^3=64\times 1 inch^3[/tex]

A = 4 inch

4 inches is the edge length of the container.

if y =6.6 when x=9.9, find y when x=6.6

Answers

I believe that the answer would be 3.3. When x=9.9 y is 3.3 less than 9.9 making it 6.6. So when x=6.6 y should be 3.3 less. Which would be 3.3. Hope this helps:)
To find the answer, first find y if x is 1. So, divide 9.9 by itself and -6.6 by 9.9. Then you get y = -0.666... when x = 1. Then multiply both by 6.6. You will get y = -4.4 when x = 6.6.

Find the value of x or y so that the line through the points has the given slope of (x, -8) and (-7,5); slope: -13/7

Answers

that is really easy but do it on your own

The required value of x is 112/13 which line through the points has the given slope of (x, -8) and (-7,5).

What is the slope of the line?

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

We have been given two points :(x, -8) and (-7,5)

As per the line of slope,

m = (y₂ - y₁)/(x₂ -x₁ )

Here

x₁ = x, y₁ = 8

x₂ = -7, y₂ = 5

Substitute values in the above formula

-13/7 = (5 - 8)/(-7 - x )

-13/7 = -3/(-7 - x )

-13(-7 - x ) = -21

91 + 13x = -21

13x = -21 - 91

13x = 112

x = 112/13

Therefore, the required value of x is 112/13.

What is a Linear Function?

A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.

We have been given that relationship A has a greater rate than relationship B.

Hours Worked                   Amount Paid

2                                              30.4

4                                               60.8

5                                               76

8                                             121.60

Let the number of hours worked x and the total amount paid y.

As per the given functions

⇒ y = 15.4x ...(i)

⇒ y = 15.2x ...(ii)

⇒ y = 16.4x ...(iii)

⇒ y = 14.9x ...(iv)

As per the linear function (ii),

⇒ y = 15.2×2

⇒ y = 30.4

The above is satisfy the point, therefore, it represents relationship A

Hence, the required equation is y = 15.2x which could represent relationship A.

A friend eats eats one-fifth of a pizza; you decide to eat half of what was left. How much is left after you eat the pizza?

Answers

If your friend ate 1/5 of the pizza, there is 4/5 left.

If you ate 1/2 of 4/5, you ate 2/5, and you left 2/5. Remember that to find 1/2 of 4/5, multiply the fractions to get 4/10, which simplifies to 2/5.

Final answer: 2/5 of the pizza.

it would be 2/5 since 1/5 is subtracted from your friend, and you are eating half which would be 2/5 since you have 4/5 now and 2/5 = half of 4/5. (Fun Fact: I cant even eat half a pizza).
