The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.

The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle.

Given ΔTUV

t = 820 inches

∠U = 132°

∠V = 25°

and ∠T = 180 - 132 - 25

∠T = 23°

so according to the law of sines

[tex]\frac{SinT}{t} = \frac{SinU}{u}= \frac{SinV}{v}[/tex]

so u = t*(SinU/SinT)

u = 820(Sin132/sin23)

u = 820(1.9019)

u = 1559.58 inches = 1560 inches (approx)

Hence the value of u is 1560 inches (approx).

According to the problem Brad will need 28.27 feet of edging to enclose his flower garden.

Edging in math is a technique that involves finding the maximum or minimum value of a function. It is typically used to optimize or increase the performance of a particular solution. In other words, edging is a process by which a function is “reduced” to its most efficient form. For example, a function that is non-linear can be “edged” to become more linear, thereby increasing its efficiency. Additionally, edging can be used to identify certain features within a solution, such as local maximums or minimums. Edging is an important tool in math, and it can be used in a variety of different applications, from optimization to data analysis.

Brad will need 28.27 feet of edging to enclose his flower garden. This is because the circumference of a circle is equal to 2πr, where r is the radius. Therefore, the circumference of Brad's flower garden with a radius of 4.5 feet is 28.27 feet.

Answer:

To find the cost of a hot dog and hamburger, we can set up a system of equations based on the information given. For example, let x be the cost of a hot dog and y be the cost of a hamburger. Then we have:

4x + 7y = 68 (equation 1)

7x + 3y = 67 (equation 2)

We can use substitution or elimination methods to solve the system of equations.

Substitution method:

Solve equation 1 for y in terms of x: y = (68 - 4x)/7

Substitute this expression into equation 2: 7x + 3((68 - 4x)/7) = 67

Simplifying and solving for x: 7x + 3(68 - 4x)/7 = 67

7x + 204 - 12x = 469

-5x = -401

x = 80

Substitute x = 80 back into equation 1: 4(80) + 7y = 68

320 + 7y = 68

7y = -252

y = -36

Therefore, the cost of a hot dog is $80, and the price of a hamburger is $-36 (which is not possible, it could be a typo or mistake in the given information)

2x + 9

Step-by-step explanation:

The solution to the function's operation of h(x) is -0.25x + 2.

A function connects an element x to an element f(x) also known as (y) in another set. The domain of a function refers to the x-values and the range of the function is the set of values of f(x)  i.e. (the y-values) that are produced by the values in the domain of the function, which is the set of values of x.

Given that:

f(x) = 0.25x - 2

h(x) -f(x)

We are going to simply replace the value of f(x) with h(x), i.e.

h(x) = -(0.25x - 2)

h(x) = -0.25x + 2

Therefore, we can conclude that the solution to the function's operation of h(x) is -0.25x + 2.

Step-by-step explanation:

To find the sum of two fractions with different denominators, a common denominator must be found.

In this case, the two in the denominator must be multiplied to make it 14.

14/2 = 7, so multiply 2 by 7 to get 14, and what you do to the bottom you must do to the top, so 1 * 7 = 7.

Now, your two fractions are 7/14 and 1/14. Add the numerators as the denominators are equal.

7+1 = 8

8/14 is the sum, which can be divided by 2 on the top and bottom to simplify.

8/2 = 4, and 14/2 = 7

Thw given statement " Accounting systems are important because they are a primary source of information for managers" is true.

Two categories of accounting systems exist: In the first, a small business uses a single entry system to log each transaction as a line item in a ledger. The alternative is a double entry system, in which each transaction is entered in two different accounts as both a debit and a credit.

Accounting systems are crucial since they serve as managers' main informational resource. The accounting system is likely to provide the information that is needed for many, if not most, decisions.

Step-by-step explanation:

The y-intercept of a function can be found by looking at the point where the x-coordinate is 0. In this case, the y-intercept of the function is -3, as the point (0,-3) is on the graph.

The slope of a function can be found by looking at the change in y divided by the change in x between two points on the graph. In this case, we can use the points (0,-3) and (1,-1) to find the slope. The change in y is -1 - (-3) = 2 and the change in x is 1 - 0 = 1. So the slope is 2/1 = 2.

Therefore, the equation of the function can be written in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept. So the equation of the function is:

y = 2x - 3

It's the equation of a line that pass through (0,-3) and (1,-1) and (2,1) and (3,3) and (4,5)

The equation y^2+4y represents a parabola that is open upward. The general form of a quadratic function is y = ax^2 + bx + c.

In this case, the coefficient of the x^2 term is 1, the coefficient of the x term is 4, and the constant term is 0.

This equation can be factored as y(y+4) = 0.

This equation is satisfied by y = 0 and y = -4.

Therefore, the solutions of y^2+4y = 0 are y = 0 and y = -4.

The lower bound of the 90% confidence interval for the population mean is 44.3.

To calculate the lower bound of the 90% confidence interval for the population mean, we will use the formula:

Lower bound = sample mean - (1.645 * (standard deviation / square root of sample size))

Calculate the sample mean:

Sample mean = (42.3 + 59.2 + 45.4 + 55.8 + 49.0 + 39.7 + 56.2 + 54.6 + 45.8 + 60.6 + 55.7 + 46.1 + 58.3 + 44.4) / 14 = 51.09

Using a left-hand approximation means that we will use the left endpoint of each interval to approximate the area under the curve.

a) Using 4 boxes:

The interval from 0 to 2 can be divided into 4 equal parts, so each part has a length of 0.5.

The height of each box will be the value of y at the left endpoint of each interval.

The area of each box can be calculated as follows:

For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.5 * 1 = 0.5.

For the second box, the left endpoint is (0.5, 2) and the height is 2(0.5) + 1 = 2.5. The area is 0.5 * 2.5 = 1.25.

For the third box, the left endpoint is (1, 3) and the height is 2(1) + 1 = 3. The area is 0.5 * 3 = 1.5.

For the fourth box, the left endpoint is (1.5, 4) and the height is 2(1.5) + 1 = 4.5. The area is 0.5 * 4.5 = 2.25.

The total area is the sum of the areas of all the boxes, so the total area is 0.5 + 1.25 + 1.5 + 2.25 = 5.

b) Using 8 boxes:

The interval from 0 to 2 can be divided into 8 equal parts, so each part has a length of 0.25.

The height of each box will be the value of y at the left endpoint of each interval.

The area of each box can be calculated as follows:

For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.25 * 1 = 0.25.

For the second box, the left endpoint is (0.25, 2.5) and the height is 2(0.25) + 1 = 2.5. The area is 0.25 * 2.5 = 0.625.

For the third box, the left endpoint is (0.5, 3) and the height is 2(0.5) + 1 = 3. The area is 0.25 * 3 = 0.75.

And so on, for all 8 boxes.

The total area is the sum of the areas of all the boxes, so the total area is 0.25 + 0.625 + 0.75 + ... + 3.375 = 5.125.

So, the area between the x-axis and the curve y = 2x + 1 on the interval (0, 2) can be approximated as 5 or 5.125 depending on the number of boxes used.
