If a minus b=5 and  \(a^2+b^2\)=9 then using algebraic identity ab= -8.

What is algebraic identity?

Algebraic identities are algebraic equations that are true regardless of the value of each variable. To quickly solve an algebraic statement or polynomial, algebraic identities are utilised. The calculation is simplified by it. The three mathematical algebraic identities are:

Identity 1: \((a+b)^2=a^2+b^2+2ab\)

Identity 2:\((a-b)^2=a^2+b^2-2ab\)

Identity 3:\((a^2-b^2)=(a+b)(a-b)\)

Here a-b= 5 and \(a^2+b^2\)=9.

Using algebraic identity formula,

=> \((a-b)^2\)=  \(a^2+b^2\)-2ab.

=> \(5^2\)= 9-2ab

=> 25=9-2ab

=> 2ab = 9-25

=>2ab = -16

=> ab = -16/2 = -8.

Hence the value of ab= -8.

Answer:

(a) Range: y > 2

(b) Domain: All reals

Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

A horizontal asymptote is a horizontal line that the curve gets infinitely close to, but never touches. It is displayed as a horizontal dashed line. Therefore, the horizontal asymptote of the graphed exponential function is y = 2.

Since there is a horizontal asymptote at y = 2, and the curve appears to be always above this line, it indicates that the range of the function is all y-values greater than 2.

\(\hrulefill\)

The domain of a function is the set of all possible input values (x-values).

As the x-values of graphed exponential function appear to be unrestricted, the domain of the function is all real numbers.

a) the dimension of its column space is also 2. b) the rank of A is 2. c) the nullity of matrix A is 1. d) the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

(a) The dimension of the row space of a matrix is equal to the dimension of its column space. So, if the dimension of the row space of matrix A is 2, then the dimension of its column space is also 2.

(b) The rank of a matrix is defined as the maximum number of linearly independent rows or columns in the matrix. Since the dimension of the row space of matrix A is 2, the rank of A is also 2.

(c) The nullity of a matrix is defined as the dimension of the null space, which is the set of all solutions to the homogeneous equation Ax = 0. In this case, the matrix A is a 3 x 3 matrix, so the nullity can be calculated using the formula:

nullity = number of columns - rank

nullity = 3 - 2 = 1

Therefore, the nullity of matrix A is 1.

(d) The dimension of the solution space of the homogeneous system Ax = 0 is equal to the nullity of the matrix A. In this case, we have already determined that the nullity of matrix A is 1. Therefore, the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

Answer:

Approximately 26.87 cm

Step-by-step explanation:

To find the length of side b using Heron's formula, we need to substitute the given values into the formula and solve for b:

A = √s(s-a)(s - b)(s-c)

270 = √45(45-15)(45-b)(45-39)

Simplifying the expression inside the square root:

270 = √45(30)(6)(6-b)

270 = 540√(6-b)

Squaring both sides:

72900 = 291600 - 54000b + 3240b^2

Rearranging:

3240b^2 - 54000b + 218700 = 0

Dividing both sides by 540:

6b^2 - 100b + 405 = 0

We can solve for b using the quadratic formula:

b = (-(-100) ± √((-100)^2 - 4(6)(405))) / (2(6))

b = (100 ± √13600) / 12

b ≈ 26.87 cm (rounded to two decimal places)

Therefore, the length of side b is approximately 26.87 cm.

Alyssa buys a 5 pound bag of rocks for a fish tank. She uses 1 1/8 pounds for a small fish bowl. So we need to find how much is left.

5 - 1 1/8

=40/8 - 9/8

=31/8

=3 7/8 pounds of rocks left.

Therefore, 3 7/8 pounds of rocks are remaining. The answer can be verified as follows:

If we add 1 1/8 pounds of rocks used to 3 7/8 pounds of rocks remaining, then we will get 5 pounds, which is the total amount of rocks Alyssa initially purchased. This is because the addition of the quantities of the rocks used and the remaining rocks should always equal the total quantity of rocks.

Therefore, our answer is correct and can be supported by this check. Alyssa bought a 5 pound bag of rocks for a fish tank and used 1 1/8 pounds of it for a small fish bowl.

A)  13 meters

B)  2.3 centimeters

=================================================

Work Shown:

Part A

The ruler diagram shows the building on paper is 6.5 cm wide. The right side of the building lines up with the midpoint marker between 6 and 7.

1 cm = 2 m

6.5*(1 cm) = 6.5*(2 m)

6.5 cm = 13 m is the width of the building in real life

Or you can solve it like this

(1 cm)/(2 m) = (6.5 cm)/(x meters)

1/2 = 6.5/x

1*x = 2*6.5

x = 13

------------------------

Part B

(1 cm)/(2 m) = (x cm)/(4.6 m)

1/2 = x/4.6

1*4.6 = 2*x

4.6 = 2x

x = 4.6/2

Answer:

E[X|Y = y] = E[X] (by the definition of independence)

Step-by-step explanation:

To show that E[aX + bY + c] = aE[X] + bE[Y] + c, we can use the linearity of the expected value:

E[aX + bY + c] = E[aX] + E[bY] + E[c] (by linearity of E[ ])

= aE[X] + bE[Y] + c (since E[c] = c for any constant c)

To show that Var(aX + bY + c) = aVar(X) + 2abCov(X, Y) + b2Var(Y), we can use the definition of variance:

Var(aX + bY + c) = E[(aX + bY + c - E[aX + bY + c])^2]

= E[((aX - aE[X]) + (bY - bE[Y]) + c)^2]

= E[(aX - aE[X])^2] + E[(bY - bE[Y])^2] + E[c^2]

+ 2aE[(aX - aE[X])(bY - bE[Y])] + 2cE[aX - aE[X]] + 2cE[bY - bE[Y]]

= a^2 E[(X - E[X])^2] + b^2 E[(Y - E[Y])^2] + c^2 + 2abE[(X - E[X])(Y - E[Y])]

+ 2ac(aE[X] - aE[X]) + 2bc(E[Y] - E[Y])

= aVar(X) + b^2Var(Y) + 2abCov(X, Y)

Finally, if X and Y are independent, then Cov(X, Y) = 0, so:

E[X|Y = y] = E[X] (by the definition of independence)

This means that the expected value of X given a particular value of Y is simply the expected value of X, regardless of the value of Y.

Based on the information provided, the learning rate observed by the operations manager for a new production process is 96%.Given that unit #4 took 41.47 minutes to complete, we can estimate the time required to complete unit #5 using the learning curve formula:$$T_n = T_1 \times n^{-b}$$ where Tn is the time required to complete the nth unit, T1 is the time required to complete the first unit, n is the unit number, and b is the learning rate expressed as a decimal. To use this formula, we need to first find T1.

We can do this by using the time taken to complete unit #4. We know that unit #4 took 41.47 minutes to complete. Using the formula above, we can write:

$T_4 = T_1 \times 4^{-b}$$$$41.47

= T_1 \times 4^{-0.96}$$ Solving for T1,

we get:$$T_1 = \frac{41.47}{4^{-0.96}} \approx 13.559$$

Therefore, T1 ≈ 13.559 minutes. Using this value of T1 and the learning rate of 96%, we can find the time required to complete unit #5:$$T_5 = T_1 \times 5^{-0.96}$$$$T_5 = 13.559 \times 5^{-0.96} \approx 10.016$$Therefore, the estimated time required to complete unit #5 is approximately 10.016 minutes.

A graphical tool used to help determine whether a process is in control or out of control is known as a Control Chart.

Control charts are essential in quality control and statistical process control (SPC). They allow you to monitor process performance and variability over time, enabling you to identify trends, shifts, or deviations from the established process baseline.

Control charts typically consist of a centerline, representing the process mean, and upper and lower control limits, which indicate the acceptable range of variation. Data points are plotted on the chart, and if they fall within the control limits, the process is considered to be in control. If data points fall outside the control limits or display non-random patterns, the process is considered out of control, signaling potential issues that need to be investigated and addressed.

In summary, control charts are a valuable graphical tool that assists in determining the stability of a process, facilitating continuous improvement efforts and ensuring product quality. They provide a visual representation of process variation and help identify when corrective actions are needed to bring a process back into control.
