Jorge is improving the structural stability of a table
by reinforcing the table's leg joints with triangular
cross-braces. The cross-braces will connect the
points where legs are attached to the tabletop to
the midpoint of the bottom of the table's base.
Notice in his sketch that the cross-braces will form
a 53° angle with each other, and will form two
angles that both measure x° with the legs of the
table.

Step-by-step explanation:

To convert height in cm to feet, we first convert cm to inches by multiplying with 0.393701, and then convert inches to feet by dividing by 12. So the height of 181 cm is equal to 5 feet and 11.06 inches.

In many countries, height is commonly measured in centimeters (cm) while in other countries it is measured in feet and inches. It's important to know how to convert between different units of height to understand and communicate your height correctly.

To convert a height given in centimeters to feet and inches, you can use the following conversion: 1 centimeter = 0.393701 inches and 1 foot = 12 inches.

First, you need to convert centimeters to inches. To do this, you can multiply the number of centimeters by 0.393701. For example, if you have a height of 181 cm you would do the following calculation: 181 cm x 0.393701 inches/cm = 71.06 inches.

Next, you'll need to convert inches to feet. To do this, you can divide the number of inches by 12. For example, with a height of 71.06 inches you would do the following calculation: 71.06 inches / 12 inches/foot = 5.92 feet. So the height of 181 cm is equivalent to 5 feet and 11.06 inches.

It's worth noting that the conversion factor between cm and inches is not exact, and the conversion between feet and inches is approximate, so it is possible that the final result will be slightly different depending on the precision used.

Factoring the roots, the values of A and B are given as follows:

The root of this equation is determined to be approximately 0.567143.The root is found to be approximately -0.673253.

The Newton-Raphson method is an iterative numerical technique used to find the roots of equations. In the first equation, y = f(x) = e^x - x, the initial approximation x0 is set to 0. By applying the Newton-Raphson method, successive approximations of the root are calculated until convergence is achieved. The root of this equation is determined to be approximately 0.567143.

In the second equation, x^3 + 2x^2 + 6x + 3 = 0, the root is sought within the range (-1, 0). The Newton-Raphson method is employed again, starting with an initial approximation x0 of -1. Through iterative calculations, the root is found to be approximately -0.673253.

Both equations demonstrate the effectiveness of the Newton-Raphson method in finding roots within specific ranges by iteratively refining approximations until a satisfactory solution is obtained.

Answer:

7 by 11

Step-by-step explanation:

Let's assume that the length of the rectangular patio is "l" meters and the width is "w" meters.

According to the problem statement, the perimeter of the patio is 36 meters, so we can set up the equation:

2l + 2w = 36

Simplifying this equation by dividing both sides by 2, we get:

l + w = 18

We also know that the area of the patio is 77 square meters, so we can set up another equation:

lw = 77

We now have two equations in two variables, and we can use them to solve for l and w.

From the first equation, we can solve for one variable in terms of the other:

w = 18 - l

Substituting this expression for w into the second equation, we get:

l(18 - l) = 77

Expanding the left-hand side, we get a quadratic equation:

18l - l^2 = 77

Rearranging and simplifying, we get:

l^2 - 18l + 77 = 0

This quadratic equation can be factored as:

(l - 7)(l - 11) = 0

Therefore, the solutions are l = 7 or l = 11.

If l = 7, then w = 18 - l = 11, and the dimensions of the patio are 7 meters by 11 meters.

If l = 11, then w = 18 - l = 7, and the dimensions of the patio are 11 meters by 7 meters.

Therefore, the dimensions of the patio are either 7 meters by 11 meters or 11 meters by 7 meters.

Answer:

0.05 mile per minutes

Step-by-step explanation:

Jesse's rate of hiking (miles per minute) = Total miles covered / Time covered

Miles covered = 1 mile

Time covered = 20 minutes

Jesse's rate of hiking (miles per minute) = Total miles covered / Time covered(minutes)

= 1 mile / 20 minutes

= 0.05 mile per minutes

20 minutes

= 20 × 60 seconds

= 1200 seconds

Jesse's rate of hiking (miles per seconds) = Total miles covered / Total time taken (seconds)

= 1 mile / 1200 seconds

= 0.0008333333333 miles per seconds

Approximately 0.000833 miles per seconds

Step-by-step explanation:

A firm's P/E ratio is a measure of the relationship between its market price and its net income. It is calculated by dividing the market price by the earnings per share (EPS). In this case, the firm's P/E ratio is 20.0, its market price is $31.00, and there are 1.4 million shares of stock outstanding. We can use these values to calculate the firm's net income.

First, we need to calculate the firm's earnings per share (EPS). We can do this by dividing the market price by the P/E ratio:

EPS = $31.00 / 20.0 = $1.55

Next, we can calculate the firm's net income by multiplying the EPS by the number of shares outstanding:

Net income = $1.55 * 1.4 million = $2.17 million

Therefore, the firm's net income is $2.17 million.

Answer:

A = 540 m²

Step-by-step explanation:

consider the shape split into 3 rectangles

the length is divided into 3 congruent sections

single dash = 30 m ÷ 3 = 10 m

the width is divided into 3 congruent sections

double dash = 27 m ÷ 3 = 9 m

then area (A) is the total of the 3 rectangular areas

A of left rectangle = 10 × 9 = 90 m²

A of middle rectangle = 10 × (9 + 9) = 10 × 18 = 180 m²

A of right rectangle = 10 × 27 = 270 m²

total area = 90 + 180 + 270 = 540 m²

Answer:

Step-by-step explanation:

Because the perpendicular slope of a line should be the negative reciprocal. The slope of the line is -1/4. So the slope of the perpendicular line is 4

The slope of a line that is perpendicular to the given line is -1/4.

In mathematics, slope refers to the steepness or inclination of a line. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line.

To find the slope of a line that is perpendicular to this line, we need to use the fact that the product of the slopes of perpendicular lines is always -1.

So, let's call the slope of the given line "m". The slope of a line perpendicular to this line can be found by taking the negative reciprocal of "m". That is:

slope of perpendicular line = -1/m

For example, if the given line has a slope of 4, then the slope of a line perpendicular to it would be:

slope of perpendicular line = -1/4

Thus, the answer is -1/4.

I) f is continuous at x=2

II) f is differentiable at x=2

These both f (function ) are true

The given limit can be recognized as the definition of the derivative of f at x=2. Specifically, it states that the derivative of f at x=2 is equal to 5.

Using this information, we can make the following conclusions:

I) We cannot say for sure whether f is continuous at x=2 based on the given limit alone. While a function being differentiable at a point implies that it is also continuous at that point, the converse is not necessarily true. Therefore, we would need additional information to determine whether f is continuous at x=2.

II) The given limit implies that f is differentiable at x=2, since the limit exists and is finite. Specifically, we can say that the derivative of f at x=2 exists and is equal to 5.

III) The given limit also implies that the derivative of f is continuous at x=2. This is because the limit defines a continuous function at x=2, and it is well-known that if a function is differentiable at a point, then it is also continuous at that point.

Therefore, the correct answers are II and III.
