= sqt (45*10) = sqrt (450) = 15 sqrt 2

The expression √45 × √10 is simplified using the property of square roots to give an equivalent choice of 15√2

The product √45 × √10 can be simplified by using the property of square roots that states √(a × b) = √a × √b.

By application of this property, we have that:

√45 × √10 = √(45 × 10).

To simplify further, we find that 45 and 10 have a common factor of 5, and thus,

45 × 10 = 5 × (9 × 10)

45 × 10 = 5 × 90.

Now, we can rewrite √(45 × 10) as √(5 × 90).

Using the same property again, we obtain √5 × √90. Finally, we recognize that 90 can be factored into 9 × 10.

Thus;

√45 × √10 = √(2 × 9 × 25)

√45 × √10 = √2 × √225

√45 × √10 = √2 × 15

√45 × √10 = 15√2

Therefore, the expression√45 × √10 have an equivalent of 15√2

The solution is Option A.

The translation of the center of circle is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

Let the equation for the circle A be represented as

( x - 7 )² + ( y - 1 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( 7 , 1 )

Let the equation for the circle A be represented as

( x + 8 )² + ( y - 2 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( -8 , 2 )

So , the translation of circle A to B is given by

( 7 , 1 ) to ( -8 , 2 )

So , the x coordinate is translated by 15 units to left and the y coordinate is translated by 1 unit up

Hence , the translation is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

The closed-form expression for the given summation is (3n^2 + 7n) / (2n^2). Using this formula, the sums for n = 10, 100, 1000, and 10,000 are 37/20, 307/200, 3007/2000, and 30007/20000, respectively.

The given expression can be rewritten using the summation formulas as

∑nj=1 3j+2/n2 = (3(1)+2)/n2 + (3(2)+2)/n2 + ... + (3(n)+2)/n2

Let's simplify this expression by factoring out the common term of 1/n2

= (3/n2)(1 + 2 + ... + n) + (2/n2)(1 + 1 + ... + 1)

= (3/n2)(n(n+1)/2) + (2/n2)(n)

= (3n(n+1) + 4n) / (2n2)

= (3n^2 + 7n) / (2n^2)

Therefore, we have the closed-form expression for S(n) as

S(n) = (3n^2 + 7n) / (2n^2)

Using this formula, we can find the sums for n = 10, 100, 1000, and 10,000

S(10) = (3(10^2) + 7(10)) / (2(10^2)) = 37/20

S(100) = (3(100^2) + 7(100)) / (2(100^2)) = 307/200

S(1000) = (3(1000^2) + 7(1000)) / (2(1000^2)) = 3007/2000

S(10000) = (3(10000^2) + 7(10000)) / (2(10000^2)) = 30007/20000

Therefore, the sums for n = 10, 100, 1000, and 10,000 are 37/20, 307/200, 3007/2000, and 30007/20000, respectively.

Given  a full subtractor with inputs X and Y , what is X "minus" Y, given that X = 1, Y = 0 and Yout = 1. The correct answer is indeed: b. 1

In a full subtractor circuit, the inputs X and Y represent the minuend and subtrahend, respectively, and the output Yout represents the borrow. The operation "X minus Y" is performed by subtracting the subtrahend (Y) from the minuend (X), taking into account any borrow (Yout) from the previous subtractor stage.

In the given truth table, when X = 1, Y = 0, and Yout = 1, we can see that the result of "X minus Y" is 1. This means that when subtracting 0 from 1, the result is 1.

The borrow (Yout) being 1 indicates that there was a borrow from the previous subtractor stage, which is important when performing subtraction with multiple bits. However, in this case, since we are only considering a single subtractor, we can focus on the X and Y inputs and the resulting output, which is 1.

Therefore, the correct answer is indeed:

The correct expression for f • g in the function f (x) = 2 x, g (x) = 3 x is 3 • 2 .3 x. Thus, Option C is the answer.

Given functions are f(x) = 2x, g(x) = 3x. The domain and target set for functions f and g are the set R.

We have to find the expression for f . g which is equal to f(g(x))

Now f(x) = 2x, so we replace x with g(x) in f(x) and simplify it,

f(g(x)) = 2g(x)f(g(x)) = 2(3x) f(g(x)) = 6x.

Answer:

See below.  The garden is 40' x 70.' for 2800 ft^2 total area.

Step-by-step explanation:

a)  Two 40 foot sections would require 80 feet of fencing.  Since one of the remaining sides is the rock wall, the fencing left for the fourth side, x, would be:  150' - 2*(40') = 70 feet for the fourth wall, x.  x = 70 feet.

---

b)  The total fencing available is 150 feet.  The side opposite the stone wall is length x.  (150' - x) represents the remaining fencing available for the two identical sides, which we'll say are y feet in length.

We know that x + 2y = 150'

Rearrange to find y:

  x + 2y = 150

  2y = 150 - x

  y = (150 - x)/2

Since x is 70 feet, each side would be 40 feet.

---

c)  Area of the garden is width, x, times length.  y.

      Area = x*y

      Area = (70')*(40')

     Area = 2800 ft^2

To express the area only as a function of x, we can substitute the definition of y:

   Area = x*y

   Area = x*((150-x)/2)

  Area = (150x - x^2)/2

Check:  Area = (150*70 - (70^2))/2 = 2800 ft^2  

x has meaning for the range of 0 - 70 feet.

For various levels of output, businesses in a competitive market have the following production costs. Right now, the price on the market is $4. Total Cost Quantity 0 1 10 2 13 3 18 4 25 34. Therefore,

1. Each firm maximizes profit by supplying 2 units where MR = MC.

2. At $4 market price, market not in long-run equilibrium as ATC ($6.5) > price.

3. Market reaches long-run equilibrium at $6, the minimum point of ATC curve.

To determine the units each firm will supply to maximize profit and calculate the profit, we need to examine the cost and revenue associated with each quantity of output.

Quantity                    Total Cost

0                                       1

1                                       10

2                                      13

3                                      18

4                                     25

1. To find the quantity that maximizes profit for each firm, we need to compare the marginal cost (MC) and marginal revenue (MR) at each quantity level.

Quantity   Total Cost   MC       MR

0                  1                   -       -

1                  10                 9       4

2                  13                 3       4

3                  18                 5       4

4                  25                 7       4

To maximize profit, a firm will produce where MR equals MC. Looking at the table, we can see that at a quantity of 2, the MR and MC are equal. Therefore, each firm will supply 2 units to maximize profit.

2. To determine if the market is in long-run equilibrium at a market price of $4, we need to compare the market price with the average total cost (ATC) for each firm. If the market price is equal to or greater than the ATC, the market is in long-run equilibrium.

Let's calculate the ATC for each firm at a quantity of 2:

\(ATC = \frac{Total Cost}{Quantity}\)

\(ATC = \frac{13}{2}\)

ATC = 6.5

The ATC for each firm is $6.5, which is greater than the market price of $4. Therefore, the market is not in long-run equilibrium because firms are not covering their costs and would not continue to operate in the long run.

3. To determine the price at which the market will be in long-run equilibrium, we need to find the minimum point of the average total cost (ATC) curve. This point represents the price at which firms can cover their costs and earn a normal profit in the long run.

Looking at the table, we can observe that the minimum ATC occurs at a quantity of 3. Let's calculate the ATC at this quantity:

\(ATC = \frac{Total Cost}{Quantity}\)

\(ATC = \frac{18}{3} = 6\)

Therefore, the market will be in long-run equilibrium at a price of $6, which corresponds to the minimum point of the ATC curve.

The answer is: True. When matrix A is upper triangular, its eigenvalues are located on its main diagonal. If you find the eigenvectors corresponding to each eigenvalue, you can construct an eigenvector matrix S.

An upper triangular matrix is a square matrix in which all entries below the main diagonal are zero. An eigenvector of a matrix A is a nonzero vector x such that Ax is a scalar multiple of x. That is, there exists a scalar λ such that Ax = λx.
For a complete upper triangular matrix, all of its eigenvalues are on the diagonal. To see this, consider the characteristic polynomial of a complete upper triangular matrix:
p(λ) = det(A - λI)
where I is the identity matrix. Since A is upper triangular, its determinant is the product of its diagonal entries, and det(A - λI) is a polynomial of degree n (the size of the matrix) in λ. Therefore, there are n roots of p(λ), which correspond to the eigenvalues of A. Since A is completely upper triangular, all of its eigenvalues are on the diagonal.

Now, let's consider the eigenvector matrix S of A. This is a matrix whose columns are the eigenvectors of A. Since A is upper triangular, any eigenvector of A must also be upper triangular (or zero). Therefore, the eigenvector matrix S must also be upper triangular. In summary, if a is a complete upper triangular matrix, then all of its eigenvalues are on the diagonal, and its eigenvector matrix S is upper triangular. Therefore, the statement is true.
"If A is a complete upper triangular matrix, then it has an upper triangular eigenvector matrix S." When a matrix A is upper triangular, its eigenvalues are located on its main diagonal. If you find the eigenvectors corresponding to each eigenvalue, you can construct an eigenvector matrix S. Since A is upper triangular, the eigenvector matrix S will also be upper triangular.

CI = 6.76 ± 1.96 × (2.67/√50)
CI = 6.76 ± 0.96
Therefore, the 95% confidence interval for the population means rating for Miami is: (5.80, 7.72)

We can be 95% confident that the true mean rating for Miami International Airport falls within this interval.
To develop a 95% confidence interval for the population means rating for Miami International Airport, we need to follow these steps:

1. Calculate the sample mean (x) by adding up all the ratings and dividing by the sample size (n=50).
2. Calculate the sample standard deviation (s).
3. Use a t-distribution to find the t-score for a 95% confidence interval with (n-1) degrees of freedom.
4. Calculate the margin of error (ME) using the t-score, standard deviation, and sample size.
5. Add and subtract the margin of error from the sample mean to find the lower and upper limits of the confidence interval.

To calculate the 95% confidence interval, we need to use the formula:
CI = x ± Z' (s/√n)
Where:
x = sample mean
Z' = z-score for the desired confidence level (in this case, 95%, so

Z' = 1.96)
s = sample standard deviation
n = sample size

Step 1: Calculate the sample mean (x)
Sum of ratings = 346
Sample size (n) = 50
x = 346/50 = 6.92

Step 2: Calculate the sample standard deviation (s)
Variance = [(Sum of (rating - x)^2) / (n-1)] = 88.48
Standard deviation (s) = √(88.48) = 9.41

Step 3: Find the t-score
For a 95% confidence interval with 49 (n-1) degrees of freedom, the t-score is approximately 2.01.

Step 4: Calculate the margin of error (ME)
ME = t-score × (s / √n) = 2.01 × (9.41 / √50) = 2.01 × 1.33 = 2.67

Step 5: Find the confidence interval
Lower limit: x - ME = 6.92 - 2.67 = 5.80
Upper limit: x + ME = 6.92 + 2.67 = 7.72

Thus, the 95% confidence interval for the population mean rating for Miami International Airport is approximately
