Answer:

3*f-7

Step-by-step explanation:

OK; "subtract from" means to do the "from" first and then subtract the number off of the "from." In this case, the "from" is 3*f. Then, subtrat seven. That gives you 3*f-7. No need for parenthesis because of PEMDAS.

The cofactors of the matrix \(\left[\begin{array}{ccc}1&2\\4&5\end{array}\right]\) are \(A_{11}\)=5,\(A_{12}\)=-4,\(A_{21}\)=-2,\(A_{22}\)=1.

Given that the matrix is \(\left[\begin{array}{ccc}1&2\\4&5\end{array}\right]\).

We are told to find the cofactors of the matrix.

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns which is basically used to represent a mathematical object or a property of such an object.

The Cofactor is the number you get when we remove the column and row of a designated element in a matrix, which is just a numerical grid in the form of rectangle or a square.

Suppose the matrix is \(\left[\begin{array}{ccc}1&2\\4&5\end{array}\right]\).

Cofactors are as under:

\(A_{11}\)=5

\(A_{12}\)=-4

\(A_{21}\)=-2

\(A_{22}\)=1

Hence the cofactors of the matrix \(\left[\begin{array}{ccc}1&2\\4&5\end{array}\right]\) are \(A_{11}\)=5,\(A_{12}\)=-4,\(A_{21}\)=-2,

\(A_{22}\)=1.

Answer: D

Step-by-step explanation:

When an inequality is multiplied or divided by a negative number, the inequality sign will flip, meaning it will change its direction. For example, if you have a > b and you multiply or divide both sides by a negative number, the inequality will become a < b. This is because the relationship between the values reverses when multiplied or divided by a negative number.

Explanation:

When an inequality is multiplied or divided by a negative number, the direction of the inequality sign is flipped. This is because multiplication or division by a negative number, results in a reversal of the order of the numbers on the number line.

To see why this happens, consider the following example:

Suppose we have the inequality x < 5. If we multiply both sides of this inequality by -1, we get -x > -5. Notice that we have flipped the inequality sign from "<" to ">". This is because multiplying by -1 changes the sign of x to its opposite, and also changes the sign of 5 to its opposite, resulting in a reversal of the order of the numbers on the number line.

Similarly, if we divide both sides of the inequality x > 3 by -2, we get (-1/2)x < (-3/2). Here, we have again flipped the inequality sign from ">" to "<". This is because dividing by a negative number also changes the order of the numbers on the number line.

In general, if we have an inequality of the form a < b or a > b, where a and b are real numbers, and we multiply or divide both sides by a negative number, we obtain:

If we multiply by a negative number, the inequality sign is flipped. For example, if a < b and c < 0, then ac > bc.

If we divide by a negative number, the inequality sign is also flipped. For example, if a > b and c < 0, then a/c < b/c.

Therefore, it is important to be mindful of the signs of the numbers involved when performing operations on inequalities. If we multiply or divide by a negative number, we must flip the direction of the inequality sign accordingly.

Answer:

give me my points

Step-by-step explanation:

(a) The profit function is given by P(x) = R(x) - C(x), where R(x) is the revenue function.
(b) To maximize profit, the company should manufacture the number of infant car seats that corresponds to the maximum point of the profit function. The maximum monthly profit can be determined by evaluating the profit function at this point. The price for each infant car seat can be found by substituting the optimal production level into the price-demand equation.

(a) The profit function, P(x), is calculated by subtracting the cost function, C(x), from the revenue function, R(x). The revenue function is determined by multiplying the price, p, by the quantity sold, x. In this case, the price-demand equation x = 9000 - 30p gives us the quantity sold as a function of the price. So, the revenue function is R(x) = p * x. Substituting the given price-demand equation into the revenue function, we have R(x) = p * (9000 - 30p). Therefore, the profit function is P(x) = R(x) - C(x) = p * (9000 - 30p) - (150000 + 30x).
(b) To maximize profit, we need to find the production level that corresponds to the maximum point on the profit function. This can be done by finding the critical points of the profit function (where its derivative is zero or undefined) and evaluating them within the feasible range. Once the optimal production level is determined, we can calculate the maximum monthly profit by substituting it into the profit function. The price for each infant car seat can be obtained by substituting the optimal production level into the price-demand equation x = 9000 - 30p and solving for p.

Answer:

x = -1

Step-by-step explanation:

Given equation:

\(\log_5(24-x)+\log_5(-x)=2\)

\(\textsf{Apply the log Product law}: \quad \log_ax + \log_ay=\log_axy\)

\(\implies \log_5[-x(24-x)]=2\)

\(\implies \log_5(x^2-24x)=2\)

\(\textsf{Apply the log law}: \quad \log_ab=c \iff a^c=b\)

\(\implies 5^2=x^2-24x\)

Simplify:

\(\implies x^2-24x-25=0\)

Factor the quadratic equation:

\(\implies x^2+x-25x-25=0\)

\(\implies x(x+1)-25(x+1)=0\)

\(\implies (x-25)(x+1)=0\)

Apply the zero product property:

\(\implies x-25=0 \implies x=25\)

\(\implies x+1=0 \implies x=-1\)

As logs of negative numbers cannot be taken, x = -1 is the only valid solution.

Check by substituting x = -1 into the original equation:

\(\implies \log_5(24-(-1))+\log_5(-(-1)\)

\(\implies \log_5(25)+\log_5(1)\)

\(\implies \log_5(5^2)+0\)

\(\implies 2\log_5(5)\)

\(\implies 2(1)\)

\(\implies 2\)

Hence, the solution is:

The power of a hypothesis test occurs when the null hypothesis is false, and we reject it. If a 95% confidence interval does not contain the hypothesized value, we can reject that value at a 0.05 alpha level.

The power of a hypothesis test refers to the probability of correctly rejecting the null hypothesis when it is false. It represents the ability of the test to detect a true effect or difference. When the null hypothesis is false and we reject it, we are making a correct decision.

If we construct a 95% confidence interval that does not contain the hypothesized value, it means that the hypothesized value is unlikely to be true. In this case, we can reject that value at a 0.05 alpha level, which means that the likelihood of the hypothesized value being true is less than 5%.

However, we cannot reject that value at a 0.95 alpha level, as this level of significance would require stronger evidence to reject the null hypothesis. Therefore, if the 95% confidence interval does not contain the hypothesized value, we can reject it at a 0.05 alpha level, but not at a 0.95 alpha level.

Step-by-step explanation:

False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.

In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.

When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.

In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.

However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.

Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.
