To find the absolute maximum value of the function g(x)=−2x^2/x−1 over the closed interval [−3,5], we will use the Extreme Value Theorem (EVT).EVT states that if a function is continuous over a closed interval, then the function will have an absolute maximum and minimum over that interval.

So, for finding the absolute maximum value of the given function, we will follow these steps:Step 1: Check the function's domain.We know that the denominator of the function g(x) is x - 1, so the function is not defined at x = 1. However, the closed interval we are working with is [-3, 5], which does not include x = 1. Hence, the function is defined over this interval.Step 2: Find the critical points of the functionTo find the critical points, we need to differentiate the function g(x) and equate it to zero:g'(x) = (-4x(x-1) + 2x^2)/(x-1)^2= 2x(3-x)/(x-1)^2=0So, the critical points of g(x) are x = 0 and x = 3.Step 3: Find the end-point values of the functiong(-3) = -2/5, g(5) = -50/9.

Step-by-step explanation:

The formula for K in terms of F is \(K = \frac{5}{9} (F-32) + 273\)

The given expression:

\(F = \frac{9}{5} (K-273) + 32\)

To find the formula for K

The formula for K is obtained by making K the subject of the formula as shown below:

\(F = \frac{9}{5} (K-273) + 32\)

subtract 32 from LHS.

\(F-32 = \frac{9}{5} (K-273)\)

multiply 5 with LHS

\(5(F-32) = 9(K-273)\)

Take numerator 9 to LHS

\(\frac{5}{9}(F-32) = K-273\)

take -273 from RHS to LHS

\(\frac{5}{9}(F-32) + 273 = K\)

Thus the formula for K in terms of F is \(K = \frac{5}{9} (F-32) + 273\)

Answer:

Profit = $200

Step-by-step explanation:

Total revenue = $9,500

Fixed expenses = $9,000

Variable expenses = $300

Total expenses = Fixed expenses + Variable expenses

= $9,000 + $300

= $9,300

Total expenses = $9,300

Profit is when revenue is greater than expenses

Loss is when revenue is less than expenses

Mia made profit because her revenue is more than her expenses

Profit = Revenue - Expenses

= $9,500 - $9,300

= $200

Profit = $200

Sure, here are the steps to solve this problem:

1. Since the scale of the blueprint is 1:40, it means that any 1 unit on the blueprint represents 40 units on the actual building.

2. The room on the building measures 3.4 m by 4.8 m.

3. So for the dimensions of the room on the blueprint, we divide the measurements by the scale ratio.

4. 1:40 scale means 1 unit = 40 units.

5. So,

3.4 m / 40 units = 0.085 units = 0.08 units (round to 0.08 units)

4.8 m / 40 units = 0.12 units

6. Therefore, the room on the blueprint measures 0.08 units by 0.12 units.

Answer:6

Step-by-step explanation:

3 * 2 = 6

A function that satisfies the condition of having its square plus the square of its derivative equal to 1 is given by f(x) = sin(x).

The function f(x) = sin(x) has the property that its square, sin^2(x), is equal to 1 when added to the square of its derivative, \($\frac{d}{dx}\sin(x))^2 = \cos^2(x)$\).

This can be seen by directly evaluating the expression: \(sin^{2}(x) + cos^{2}(x) = 1\), which is a fundamental identity in trigonometry.

The sine function is periodic with a period of 2π, and its derivative, cosine function, also has the same period. This means that for any x, the function sin(x) and its derivative cos(x) will satisfy the given condition.

Geometrically, the sine function represents the y-coordinate of a point on the unit circle as the corresponding angle is varied. Its derivative, the cosine function, represents the rate of change of this y-coordinate with respect to the angle. The squares of the sine and cosine functions add up to 1, which is the square of the radius of the unit circle. This property is fundamental in trigonometry.

THANK YOU FOR READING.

The rocket's speed in feet per second, during take-off is 18.77

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

Given;

Speed of rocket in miles per hour=12800

or, 12800miles/hour

1 mile= 52800feet

Conversion is as follows;

12800miles= 52800 x 12800 feet

=675840000feet

1hour= 60 x 60seconds

=3600seconds

To multiply mixed numbers, convert to improper fractions, cancel factors, multiply the remaining factors, and simplify if possible.

Increasing blended numbers can be tedious, yet there is an easy route that can work on the interaction. To duplicate blended numbers, convert them to ill-advised portions, then drop any elements that show up in both the numerator and denominator of the divisions. At long last, duplicate the leftover elements in the numerator and denominator and work on the subsequent division if conceivable. For instance, to duplicate 2 1/2 by 3 2/3, first proselyte them to inappropriate divisions, which are 5/2 and 11/3. Then, drop the variable of 2 in the numerator of the principal portion and the denominator of the subsequent division. The outcome is 55/3, which can be improved to 18 1/3. This alternate way can save time and assist understudies with taking care of augmentation issues all the more proficiently.

To determine the critical value of F for a one-way between-subjects ANOVA with 5 levels and 48 people, we need to find the degrees of freedom for the numerator and the denominator.

The numerator degrees of freedom (df₁) is equal to the number of levels minus 1, which is 5 - 1 = 4.

The denominator degrees of freedom (df₂) is equal to the total number of people minus the number of levels, which is 48 - 5 = 43.

Using these degrees of freedom, we can look up the critical value of F from the F-distribution table or use statistical software.

For an alpha level of 0.01 and df₁ = 4 and df₂ = 43, the critical value of F is approximately 3.737.

Therefore, the correct answer is B. 3.737.

This problem can be solved using the principle of inclusion-exclusion. Let A be the event that at least one letter is in the correct envelope. We want to find the probability of the complement of A, which is the event that no letter is in its proper envelope.

The total number of ways to put the letters into the envelopes is 4!, since each letter can go into any of the 4 envelopes. Now we need to count the number of ways that at least one letter is in the correct envelope.

Let Bi be the event that the ith letter is in the correct envelope. By the principle of inclusion-exclusion, the number of ways that at least one letter is in the correct envelope is:

|B1 U B2 U B3 U B4| = Σ|Bi| - Σ|Bi Bj| + Σ|Bi Bj Bk| - |B1 B2 B3 B4|

where |S| denotes the number of outcomes in the set S, and the summations are over all possible pairs and triples of indices i, j, k.

Since there are 4 letters, we have:

|Bi| = 3! = 6 for each i

|Bi Bj| = 2! = 2 for each pair (i,j)

|Bi Bj Bk| = 1 for each triple (i,j,k)

|B1 B2 B3 B4| = 1

Substituting these values into the equation above, we get:

|B1 U B2 U B3 U B4| = 4(6) - 6(2) + 1 = 9

Therefore, the number of ways that no letter is in its proper envelope is:

|A'| = 4! - |B1 U B2 U B3 U B4| = 24 - 9 = 15

The probability of this event is:

P(A') = |A'|/4! = 15/24 = 5/8

So the probability that no letter is in its proper envelope is 5/8.

=11+ 1  ( this is obtained by solving)

b. 4x - 7y - 5z + 6

=4x+ (-7y) + (-5z) +6

We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.

c. -3x - 8y - 4 - 8/7z

-[ 3x+8y+4+8/7z]

1. The statement "A low value is desirable to save energy value and is the inverse of R value" is true. The R-value is a measure of the resistance of a material to heat flow, while the U-value is the inverse of the R-value and represents the rate of heat transfer through a material. A low U-value indicates good insulation and lower heat loss, which is desirable for saving energy. For example, if a material has a high R-value, it means that it resists heat flow and has a low U-value, indicating that it is a good insulator.

2. The statement "Air leakage is not a significant source of heat loss" is false. Air leakage can be a significant source of heat loss in a building. When warm air escapes through cracks or gaps in the building envelope, it can result in energy waste and higher heating costs. For example, if there are gaps around windows or doors, or holes in the walls, cold air can infiltrate the building and warm air can escape. To reduce heat loss, it is important to have an effective air barrier that seals the building envelope and minimizes air leakage.

In summary, a low U-value is desirable to save energy and is the inverse of the R-value. Additionally, air leakage can be a significant source of heat loss, so having an effective air barrier is important to minimize energy waste
