A rectangle with base b and height h has an area of 235 square-inches. Express the perimeter of the rectangle as a function of its base

Answers

The perimeter of the rectangle as a function of its base is P = 2(b + 235/b)

What are perimeters?

The perimeter of a shape is the sum of the side lengths of the shape For all regular quadrilaterals, you add up the side lengths to determine the area

How to express the perimeter of the rectangle as a function of its base?

The given parameters are

Area = 235 sqare inches

The area of a rectangle is calculated using

Area = Base * Height

Note that the area of a shape is the amount of space on the shape

Recall that the area of a rectangle is calculated using

Area = Base * Height

Rewrite the above equation as

A = bh

So, we have

bh = 235

Make h the subject of the formula

h = 235/b

The perimeter of the rectangle is

P = 2(b + h)

So, we have

P = 2(b + 235/b)

Hence, the perimeter of the rectangle as a function of its base is P = 2(b + 235/b)

A garden table and a bench cost $700 combined. The garden table costs $50 less than the bench. What is the cost of the bench?

Answers

The bench costs $325

Cost of bench = x

Cost of garden table = x - 50

x - 50 + x = 700

2x - 50 = 700

2x = 750

x = 325

Cost of bench=x. Cost of garden table=x-50 X-50+x=700 2x-50=700 2x=750 X=375

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2 .



The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!



Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)



Part b: Find two values of x that will create a profit of $50 .



The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2;4;6 or x+1;x−1 ). The order of the list does not matter. To enter a−−√ , type sqrt(a).

Answers

The equation for the profit from selling the items is P =  40x-0.5x²-300. The values of x are 10 and 70.

How to solve for the expression

We have the cost function in this question to be

Cx = 60x+300

Revenue = 100x−0.5x²

A. The revenue function is stated as the revenue - cost

= (100x−0.5x²)-60x+300

We have to open the equation

40x-0.5x²-300

B. when profit is 50 dollars

50 = 40x-0.5x²-300

We have to multiply both sides by 10

500 = 400x - 5x² - 3000

We have to collect like terms and form a quadratic equation

5x² - 400x - 3500 = 0

We have to solve the quadratic equation above using a quadratic calculator.

Hence

x = 10, 70

So the two values that would create a profit of 50 dollars is 10 and 70.

DEF and RST are complementary angles. If DEF is (3(-5 + 2x)) and RST is (x - 7), what is the measure of DEF?

Answers

From the given information, the measure of DEF is 81°

Calculating the measure of angles

From the question, we are to determine the measure of DEF

From the given information,

DEF and RST are complementary angles. This means they sum up to 90°

Thus,

(3(-5 + 2x)) + (x - 7) = 90

(3(-5 + 2x)) + (x - 7) = 90

(-15 + 6x) + (x - 7 ) = 90

-15 + 6x + x - 7 = 90

6x + x = 90 + 15 + 7

7x = 112

x = 112/7

x = 16

Then, substitute the value of x to determine the measure of DEF

(3(-5 + 2x))

= (3(-5 + 2(16)))

= (3(-5 + 32))

= (3(27))

= 81°

Hence, the measure of DEF is 81°

The professor has given them a take-home exam for their mid-term, and they want your help completing the exam. Is this an academic integrity violation? Why or why not? How would you handle this situation, and why would you handle it in that way?

Answers

This is an academic integrity violation because it is against honesty rules, the best would be to offer assistance to your friend.

Is this an academic integrity violation?

Academic integrity encompasses principles of honesty, fairness, and trustworthiness in academic pursuits. It generally includes a commitment to originality and independent work. Assisting someone in completing an exam, especially a take-home exam, where individual effort and understanding are expected, would likely violate academic integrity policies.

Handling this situation

Handling the situation ethically and responsibly would involve respecting the academic rules and ensuring fairness for all students. Instead of directly completing the exam for your friend, you can offer assistance by explaining concepts, providing guidance on problem-solving approaches, or reviewing their completed work to identify errors or areas for improvement. This way, you can help your friend learn the material and develop their own understanding, without compromising academic integrity.

Encourage your friend to seek additional help from their professor, teaching assistants, or tutoring services provided by the institution. They can also engage in group study sessions or form study groups with classmates, which promote collaborative learning while maintaining individual effort.

x+6y=28, solve for y

Answers

Answer:

[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]

Step-by-step explanation:

So when you're solving for y you want to get y by it self meaning there should be nothing with y, including any coefficients. The first step is to usually move any terms to the other side and then divide by the coefficient of y so y "technically doesn't" have a coefficient, while it does, but that coefficient 1, so it doesn't really mean much.

Subtract x from both sides

[tex]6y = -x+28[/tex]

Divide both sides by 6

[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]

The given equation solved for y as y = (28 - x)/6.

The given equation is x+6y=28.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved for y as follows

Here, x+6y=28

⇒ 6y = 28 - x

⇒ y = (28 - x)/6
