The length of the longest possible ladder that can negotiate the turn in the hallway is approximately 16.86 feet.

To find the length of the longest ladder, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the hallway forms a right-angled triangle, with one side measuring 14 feet and the other side measuring 8 feet.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse (the ladder) as follows:

\(c^2 = a^2 + b^2\)

where c is the hypotenuse (length of the ladder), and a and b are the lengths of the other two sides.

Plugging in the values:

\(c^2 = 14^2 + 8^2\)

\(c^2 = 196 + 64\)

\(c^2 = 260\)

c ≈ √260

c ≈ 16.86 feet

Therefore, the length of the longest possible ladder that can negotiate the turn in the hallway is approximately 16.86 feet.

This represents adding 17 to the additive inverse of 19. By doing so, we effectively subtract 19 from 17.

To rewrite the subtraction expression "17 - 19" using addition without changing the digits, we can use the concept of additive inverse. The additive inverse of a number is the number that, when added to the original number, yields zero.

In this case, we want to rewrite the expression "17 - 19" using addition. We can think of it as finding the additive inverse of 19 and adding it to 17.

An additive inverse of a number is defined as the value, which on adding with the original number results in zero value. It is the value we add to a number to yield zero. Suppose, a is the original number, then its additive inverse will be minus of a i.e.,-a, such that; a+(-a) = a – a = 0.

The additive inverse of 19 is -19, since 19 + (-19) equals zero. Therefore, we can rewrite the subtraction expression as follows:

17 + (-19)

A product has a production cost function ​C(x) =165x + 3630 and a revenue function ​R(x)= 220x. Find and analyze the​ break-even quantity, then find the profit function.

Answer:

the break-even  quantity = 66

the profit function = 55x - 3630

Step-by-step explanation:

Given that:

C(x) = 165x + 3630

R(x) = 220 x

The Break-even quantity is C(x) = R(x)

∴

165x + 3630 = 220x

collecting the like terms, we have:

3630 = 220 x - 165 x

3630 = 55 x

\(x = \dfrac{3630}{55}\)

x = 66

Thus, the break-even  quantity = 66

The profit function = R(x) - C(x)

The profit function = 220x - 3630 - 165x

By rearrangement

The profit function = 220x - 165x - 3630

The profit function = 55x - 3630

the correct format for a multiple regression equation is

ŷ= \(b_{o} + b_{1}x_{1} + b_{2}x_{2} + b_{3}x_{3} + b_{4}x_{4}\)

multiple regression: The relationship between a single dependent or criterion variable and multiple independent or predictor variables is typically explained by multiple regression. The constant term and multiple independent variables with their corresponding coefficients are used to model a dependent variable. The term "multiple regression" refers to the fact that it requires two or more predictor variables.

because, the weight of a passenger vehicle, in kilograms, is related to its length, in centimeters; and the maximum number of passengers.

thus, ŷ=\(b_{o} + b_{1}x_{1} + b_{2}x_{2} + b_{3}x_{3} + b_{4}x_{4}\) is the multiple regression equation.

"An inaccurate assumption often made in statistics is that variable relationships are linear". The statement is true.

In statistics, it is indeed an inaccurate assumption to assume that variable relationships are always linear. While linear relationships are commonly encountered in statistical analysis, many real-world phenomena exhibit nonlinear relationships. Nonlinear relationships can take various forms, such as quadratic, exponential, logarithmic, or sinusoidal patterns.

By assuming that variable relationships are linear when they are not, we risk making incorrect interpretations or predictions. It is essential to assess the data and explore different types of relationships using techniques like scatter plots, correlation analysis, or regression modeling. These methods allow us to identify and account for nonlinear relationships, providing more accurate insights into the data.

Therefore, recognizing the possibility of nonlinear relationships and employing appropriate statistical techniques is crucial for obtaining valid results and making informed decisions based on the data.

Answer: x < -46/17

Step-by-step explanation:

To solve the inequality:

1/3x - 1/4(x + 2) > 3x - 4/3

First, we simplify the left-hand side by finding a common denominator:

4(1/3x) - 3/4(x + 2) > 3x - 4/3

4/3x - 3/4x - 9/2 > 3x - 4/3

Next, we simplify the equation:

7/12x - 9/2 > 3x - 4/3

To isolate the variable x on one side of the inequality, we will move all the x terms to the left-hand side and all the constants to the right-hand side:

7/12x - 3x > 9/2 - 4/3

-17/12x > 23/6

Finally, we can solve for x by dividing both sides by -17/12, remembering to reverse the inequality because we are dividing by a negative number:

x < (23/6) ÷ (-17/12)

x < -46/17

Therefore, the solution to the inequality is:

x < -46/17

The solutions to the equation log4(x² - 2x) = log4(3x + 8) are x = 8 and x = -1.

To solve the equation log4(x² - 2x) = log4(3x + 8), we can use the property of logarithms that says if logb(a) = logb(c), then a = c.

Using this property, we can set the expressions inside the logarithms equal to each other:

x² - 2x = 3x + 8

Now we have a quadratic equation that we can solve:

x² - 2x - 3x - 8 = 0 x² - 5x - 8 = 0

We can factor this equation using the product-sum method:

x² - 5x - 8 = (x - 8)(x + 1)

Setting each factor equal to zero gives us the possible solutions:

x - 8 = 0 or x + 1 = 0

Solving for x in each case gives us:

x = 8 or x = -1

However, we need to check if either of these solutions make the argument of the logarithm negative or zero. If the argument is negative or zero, then the logarithm is undefined.

For the first solution, x = 8, we have:

log4(8² - 2(8)) = log4(3(8) + 8) log4(48) = log4(32)

Both arguments are positive, so x = 8 is a valid solution.

For the second solution, x = -1, we have:

log4((-1)² - 2(-1)) = log4(3(-1) + 8) log4(3) = log4(5)

Again, both arguments are positive, so x = -1 is also a valid solution.

Therefore, the solutions to the equation log4(x² - 2x) = log4(3x + 8) are x = 8 and x = -1.

Answer:

\(x=\sqrt6\\y=\sqrt{12}\)

Step-by-step explanation:

We know that since angles in a triangle add up to 180º, the remaining angle must be 45º.

So the side with length \(x\) must be equal to the side with length \(\sqrt6\). That is:

\(x=\sqrt6\)

Now, by Pythagoras:

\(y=\sqrt{(\sqrt6)^2+(\sqrt6)^2}\\=\sqrt{6+6}\\=\sqrt{12}\)

Answer:

\(x=\sqrt{6}\)

\(y=2\sqrt{3}\)

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

So the missing angle = 180 - 45 - 90 = 45°

Therefore, as two of the interior angles are congruent (both 45°), this is an isosceles triangle.  This means that the two shorter sides are equal,

so \(x=\sqrt{6}\)

Use Pythagoras' Theorem to calculate y:

\(y=\sqrt{(\sqrt{6})^2+(\sqrt{6})^2 } =\sqrt{12} =2\sqrt{3}\)

Answer:

zero of the function occurs at x = -6

Step-by-step explanation:

Given f(x) = -4(x+3)+6(x+4)

Since the question is incomplete, we can as well find the zero of the given function. The zero exists when f(x) = 0

Hence;

-4(x+3)+6(x+4) = 0

Expand

-4x - 12 + 6x + 24 = 0

Collect the like terms

-4x + 6x - 12 +24 = 0

2x + 12 = 0

2x = -12

x = -12/2

x = -6

Hence the zero of the function occurs at x = -6
