If Sqrt(4 + X) + (10 X) = 6 , Then Find Sqrt(4 + X)(10 X) Algebraically.

Answers

Answer 1

The algebraic expression for √(4+x)(10-x), which is 121.

To find the value of √(4+x)(10-x) algebraically, we start by simplifying the given equation:

√(4+x) + √(10-x) = 6

To eliminate the square roots, we can square both sides of the equation:

(√(4+x) + √(10-x)[tex])^2 = 6^2[/tex]

Expanding the left side using the binomial formula, we get:

(4+x) + 2√[(4+x)(10-x)] + (10-x) = 36

Simplifying further:

14 + 2√[(4+x)(10-x)] = 36

Subtracting 14 from both sides:

2√[(4+x)(10-x)] = 22

Dividing both sides by 2:

√[(4+x)(10-x)] = 11

Now we can square both sides again to get rid of the square root:

[(4+x)(10-x)] = [tex]11^2[/tex]

Simplifying further:

(4+x)(10-x) = 121

A house on the market was valued at 432,000. After several years, the value decreased by 9%. By how much did the house's value decrease in dollars? What is the current value of the house?

Answers

Answer:

$393,120

Step-by-step explanation:

To find the decrease in the house's value in dollars, we need to calculate 9% of the initial value:

Decrease in value = (Initial value) * (Percentage decrease) = $432,000 * 9%

Converting the percentage to a decimal:

Decrease in value = $432,000 * 0.09 = $38,880

The house's value decreased by $38,880.

Now, to find the current value of the house, we need to subtract the decrease in value from the initial value:

Current value = Initial value - Decrease in value = $432,000 - $38,880 = $393,120

The current value of the house is $393,120.

Hope this helps!

However, this encourages bureaucracy and can reduce flexibility, a real handicap in today's environment. As a result, some companies are experimenting with "banding," or making wider groups of jobs with similar pay. This reduction in the specificity of the structure increases the adaptability of the organization, but can cause some problems.In this exercise, please read the mini-case and answer the questions that follow.Ray Wilson is Quality Manager of the Tiffin, Ohio plant of North-West Electric, a manufacturer of electrical components. Some North-West locations have implemented various forms of broad-banding and delayering in response to job-based pay structures. He heard about the experiences of Tiffin's sister plant in Kinston, North Carolina at a recent quality conference. This made him consider his own situation. His staff is generally effective, but they do not always do well in the highly ambiguous environment of the plant because their defined responsibilities do not incorporate a great deal of flexibility, and many of them are reluctant to step outside their roles. There are four levels of employees between him and his hourly staff; Ray sometimes feels overly insulated from the happenings on the shop floor. Now, Ray has to decide whether or not to try this approach with his own staff, and what specifically to do if he does make changes.3a.
