using (tr-tc) approach, what is the maximum number of workers to attain maximum profit. why?

Answer: The length of one side of the triangular-shaped walking path is 330 feet.

Step-by-step explanation:

The perimeter of the triangular-shaped walking path is 990 feet, and the length of one side is represented by x. We can write an equation to find x using the formula for the perimeter of a triangle:

P = a + b + c

Where P is the perimeter, and a, b, and c are the lengths of the sides of the triangle. Since one of the sides is represented by x, the equation can be written as:

990 = x + x + x

Simplifying the equation, we can find the value of x:

990 = 3x

Dividing both sides by 3, we get:

330 = x

So the length of one side of the triangular-shaped walking path is 330 feet.

The resulting equation is 14√3x - 47 = 0.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

√3x + 4 = 1 + √3x -11

√3x + 4 = √3x - 10

Squaring both sides

(√3x + 4)² = (√3x - 10)²

3x² + 16 + 8√3x = 3x² - 20√3x + 100

16 - 100 + 8√3x + 20√3x = 0

28√3x - 94 = 0

2(14√3x - 47) = 0

14√3x - 47 = 0

Thus,

14√3x - 47 = 0 is the resulting equation.

When both sides of the given equation are squared, the resulting equation is x = 20.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

√(3x+4) = 1+√(3x-11)

Squaring both sides of the equation:

3x + 4 = (1 + √(3x - 11))²

Expanding the square on the right side:

3x + 4 = 1 + 2√(3x - 11) + (3x - 11)

Simplifying the above equation, we get

196 = 12x - 44

12x = 196 + 44

12x = 240

The measure of ∠C found using central angle and intercepted angle relationship is 50°.

What is central angle and intercepted arc of a circle?

An angle with its vertex at the circle's centre and both of its endpoints are on circle is said to be central angle. The angle's intercepted arc's ends are the same as the circle's endpoints. A circle's circumference includes an arc. Therefore, an intercepted arc is an arc that is created when one or more chords or line segments intersect a circle and come together at a vertex.

Given,

∠AFE = 150°

arc BD =  50°

External angle formed outside a circle,

= 1/2 ( major arc -  minor arc )

Major arc = intercepted arc AE =  central angle ∠AFE = 150°

Minor arc = arc BD =  50°

Therefore external angle ∠C = 1/2(150-50) = 50°

Hence 50° is the measure of ∠C.

The value of x and y in the given triangle is 4 and 6 respectively.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

The two triangles are similar. Using the rule of similar triangles we have:

4/ 6 = y / y+3

4(y + 3) = 6y

4y + 12 = 6y

12 = 2y

Answer:

The marked price of the torchlight is Rs. 1960.

Step-by-step explanation:

The marked price (MP) of a torchlight is 40% more than the cost price (CP), so we can calculate the MP using the formula:

MP = CP + (CP x 40%)

The cost price of the torchlight is Rs. 1400, so the marked price is:

MP = 1400 + (1400 x 40%) = 1400 + 560 = 1960

The shopkeeper is selling the torchlight at a 20% discount, so we can calculate the selling price (SP) using the formula:

SP = MP - (MP x 20%)

The marked price of the torchlight is Rs. 1960, so the selling price is:

SP = 1960 - (1960 x 20%) = 1960 - 392 = 1568

So the marked price of the torchlight is Rs. 1960.

Answer:

A) (3x + y)^4:

The Binomial Theorem states that for any real numbers a and b, and any positive integer n, the expansion of (a + b)^n is given by the sum of n terms of the form:

C(n,k)a^(n-k)b^k

where C(n,k) is the binomial coefficient (n choose k).

So, expanding (3x + y)^4:

(3x + y)^4 = C(4,0)(3x)^4(y)^0 + C(4,1)(3x)^3(y)^1 + C(4,2)(3x)^2(y)^2 + C(4,3)(3x)^1(y)^3 + C(4,4)(3x)^0(y)^4

Using the binomial coefficients:

C(4,0) = 1, C(4,1) = 4, C(4,2) = 6, C(4,3) = 4, C(4,4) = 1

Expanding the terms:

(3x + y)^4 = 1(3x)^4(y)^0 + 4(3x)^3(y) + 6(3x)^2(y)^2 + 4(3x)(y)^3 + 1(y)^4

= 1(81x^4) + 4(27x^3y) + 6(9x^2y^2) + 4(3xy^3) + 1(y^4)

= 81x^4 + 108x^3y + 54x^2y^2 + 12xy^3 + y^4

B)

The Binomial Theorem states that for any real numbers a and b and any positive integer n, the expansion of (a + b)^n is given by:

(a + b)^n = C(n, 0)a^n * b^0 + C(n, 1)a^(n-1) * b^1 + C(n, 2)a^(n-2) * b^2 + ... + C(n, n-1)a^1 * b^(n-1) + C(n, n)a^0 * b^n

where C(n, k) represents the binomial coefficient, which can be calculated as n! / (k! (n - k)!).

Applying this to (x - 2y)^6, we get:

(x - 2y)^6 = C(6, 0)x^6 * (-2y)^0 + C(6, 1)x^5 * (-2y)^1 + C(6, 2)x^4 * (-2y)^2 + ... + C(6, 5)x^1 * (-2y)^5 + C(6, 6)x^0 * (-2y)^6

Expanding each term:

C(6, 0) = 6! / (0! 6!) = 1

C(6, 1) = 6! / (1! 5!) = 6

C(6, 2) = 6! / (2! 4!) = 15

C(6, 3) = 6! / (3! 3!) = 20

C(6, 4) = 6! / (4! 2!) = 15

C(6, 5) = 6! / (5! 1!) = 6

C(6, 6) = 6! / (6! 0!) = 1

Now we can substitute each value into the equation:

(x - 2y)^6 = 1x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + 1 * (-2y)^6

Answer:

(x - 2y)^6 = x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + (-2y)^6.

To solve the inequality, we need to get the variable on one side and the constant on the other side. We can start by multiplying both sides of the inequality by 3:

[tex]4a ≥ 6[/tex]

Now, we can divide both sides by 4:

[tex]a ≥ \frac{3}{2}[/tex]

The solution to this inequality is all values of a that are greater than or equal to 3/2. We can represent this on a number line as:

(-infinity, -1.5) U [1.5, infinity)

Where ( -infinity, -1.5) represents all values less than -1.5 and [1.5, infinity) represents all values greater than or equal to 1.5.

Note that the solution can also be represented as a >= 1.5.

Correct option is E, The slope of a line perpendicular to y = -10/4 x + 5 is 4/10

The slope of the parallel line is undefined and the slope of the perpendicular line is 0.

Yes, the slope of a line perpendicular to the line 10x + 4y = 20 is indeed -4.

To find the slope of a perpendicular line, we can find the negative reciprocal of the slope of the original line.

The slope of line 10x + 4y = 20 can be found by solving for y and writing the line in slope-intercept form (y = mx + b), where m is the slope.

By solving for y in the equation 10x + 4y = 20:

10x + 4y = 20

4y = -10x + 20

y = -10/4 x + 20/4

y = -10/4 x + 5

So the line is in the form y = -10/4 x + 5, which is the slope-intercept form of a line where the slope (m) is -10/4 and the y-intercept (b) is 5.

Now, to find the slope of a line perpendicular to this line, we need to find the negative reciprocal of the slope of this line. The negative reciprocal of -10/4 is 4/10.
