To find the work done in winding 80ft. of cable on a drum, we need to calculate the total weight of the cable being wound.

Given that the cable weighs 6lb/ft and we are winding 80ft. of cable, the weight of the cable being wound is:

Weight = 6lb/ft * 80ft = 480lb.

Now, we need to calculate the work done. Work is defined as the force applied over a distance. In this case, the force is the weight of the cable, and the distance is the length of the cable being wound.

Since the cable supports a safe weighing 800lb, the force applied to wind the cable is the difference between the weight of the cable and the weight of the safe:

Force = Weight of the cable - Weight of the safe = 480lb - 800lb = -320lb.

(Note: The negative sign indicates that the force is acting in the opposite direction of winding.)

The work done is then calculated as:

Work = Force * Distance = -320lb * 80ft = -25,600 ft-lb.

Therefore, the work done in winding 80ft. of cable on the drum is -25,600 ft-lb.

The Gram-Schmidt process is used to transform a set of linearly independent vectors into an orthogonal set of vectors. The process involves taking each vector in the set, projecting it onto the subspace spanned by the preceding vectors in the set, and then subtracting the projection from the original vector to obtain a new vector that is orthogonal to all of the preceding vectors.

Let's use the Gram-Schmidt process to transform the given basis {ū₁, ū₂, ūz} into an orthogonal basis. ū₁ = (1,0,0)This vector is already orthogonal, so we can use it as the first vector in the new basis: v₁ = ū₁ = (1,0,0)ū₂ = (3,7,-2)To obtain an orthogonal vector to v₁, we first project ū₂ onto v₁: projv₁(ū₂) = ((ū₂ · v₁)/|v₁|²) v₁= ((3,7,-2) · (1,0,0))/(1² + 0² + 0²) (1,0,0)= (3,0,0)The projection of ū₂ onto v₁ is (3,0,0), so an orthogonal vector to v₁ isū₂₁ = ū₂ - projv₁(ū₂)= (3,7,-2) - (3,0,0)= (0,7,-2)We can use this as the second vector in the new basis: v₂ = ū₂₁ = (0,7,-2)ūz = (0,4,1)To obtain an orthogonal vector to {v₁, v₂}, we first project ūz onto v₁ and onto v₂:projv₁(ūz) = ((ūz · v₁)/|v₁|²) v₁= ((0,4,1) · (1,0,0))/(1² + 0² + 0²) (1,0,0)= (0,0,0)projv₂(ūz) = ((ūz · v₂)/|v₂|²) v₂= ((0,4,1) · (0,7,-2))/(0² + 7² + (-2)²) (0,7,-2)= (-1/27)(0,4,1) + (2/9)(0,7,-2)= (14/27, 8/27, 10/27)An orthogonal vector to {v₁, v₂} isūz₁ = ūz - projv₁(ūz) - projv₂(ūz)= (0,4,1) - (0,0,0) - (14/27, 8/27, 10/27)= (40/27, 20/27, -17/27)We can use this as the third vector in the new basis:v₃ = ūz₁ = (40/27, 20/27, -17/27)Therefore, the basis {v₁, v₂, v₃} is an orthogonal basis that spans the same subspace as the original basis {ū₁, ū₂, ūz}.

Simplifying the system of equations, we have:

x + y - z = 0

x - y + z = 0

4x + 2y - 2z = 0

From the first equation, we can express x in terms of y and z:

x = z - y

Substituting this value of x into the second equation, we get:

(z - y) - y + z = 0

2z - 2y = 0

z = y

Now, substituting x = z - y and z = y into the third equation, we have:

4(z - y) + 2y - 2z = 0

4z - 4y + 2y - 2z = 0

2z - 2y = 0

z = y

Therefore, in this case, we have x = z - y = y - y = 0, y = y, and z = y.

Therefore, there are 175,760,000 different possible security codes that can be made with three letters followed by four digits.

For the three letters, assuming we have a standard English alphabet with 26 letters, there are 26 options for the first letter, 26 options for the second letter, and 26 options for the third letter. Therefore, the total number of options for the three letters is 26 x 26 x 26 = 17,576.

For the four digits, assuming we have decimal digits from 0 to 9, there are 10 options for each digit. So, there are 10 options for the first digit, 10 options for the second digit, 10 options for the third digit, and 10 options for the fourth digit. Therefore, the total number of options for the four digits is 10 x 10 x 10 x 10 = 10,000.

The answer based on the limit and continuity is (a) the value of the given limit is 57/89. , (b)  the value of the given limit is infinity.

(a) Here is the working shown below:

The given expression is;

2t² + 21t + 27 / 3t² + 25t - 18

To find lim t→9 2t² + 21t + 27 / 3t² + 25t - 18

We can use the rational function technique which is a quick way to evaluate limits that give an indeterminate form of 0/0.

Applying this method, we can find the limit by computing the derivatives of the numerator and denominator.

We take the first derivative of the numerator and denominator, and simplify the expression.

We then find the limit of the simplified expression as x approaches 9.

If the limit exists, then it will be equal to the limit of the original function lim x→a f(x).

Now let's start applying the same;

First, take the derivative of the numerator which is 4t + 21 and the derivative of the denominator is 6t + 25.

Put the values in the limit expression and get the following result;

lim t→9 (4t + 21)/(6t + 25)

= (4(9) + 21) / (6(9) + 25)

= 57 / 89

So, the value of the given limit is 57/89.

(b) Here is the working shown below:

The given expression is;

8t⁴²+3 + 25t¹² + 7t² / 78 - 35t⁸ – 81t⁵ + 1013

To find lim t→∞ 8t⁴²+3 + 25t¹² 3 + 7t² / 78 - 35t⁸ – 81t⁵ + 1013 t

We have to apply L'Hopital's rule here to evaluate the limit.

To do so, we have to differentiate the numerator and denominator.

Hence, Let f(x) = 8t⁴²+3 + 25t + 7t and g(x) = 78 - 35t8 – 81t5 + 1013

Now, we have to differentiate both numerator and denominator with respect to t.

Hence, f'(x) = (32t³ + 375t¹¹ + 14t) and g'(x) = (-280t⁷ - 405t⁴)

We will evaluate the limit by putting the value of t as infinity.

Hence, lim t→∞ (32t³ + 375t¹¹ + 14t)/(-280t⁷ - 405t⁴)

After putting the value, we get  ∞ / -∞ = ∞

Hence, the value of the given limit is infinity.

The correct option is:

b. Reject the null hypothesis and there is not significant evidence for alternative hypothesis.

When the critical value of the significance level is smaller than the test statistic in a right-tailed test, it means that the test statistic falls in the rejection region. This indicates that the observed data is unlikely to occur under the assumption of the null hypothesis. Therefore, we reject the null hypothesis. However, since the p-value (the probability of obtaining a test statistic as extreme as the observed value) is greater than the significance level, there is not significant evidence to support the alternative hypothesis.

(ii) The nth partial sum of the series 5/1.2 + 5/2.3 + 5/3.4 + ... is given by Sn = 5((1/n) - (1/(n+1))). The series converges to the limit 5.

(i) For the series 2 + 2/3 + 2/9 + 2/27 + ..., notice that each term can be expressed as 2/3^n. The nth partial sum, Sn, can be obtained by summing up the terms from the first term to the nth term. This can be calculated using the formula for the sum of a geometric series: Sn = a(1 - r^n) / (1 - r), where a is the first term and r is the common ratio. In this case, a = 2 and r = 1/3. Simplifying the formula gives Sn = 2(1 - (1/3)^n) / (1 - 1/3) = 3(1 - (1/3)^n). As n approaches infinity, (1/3)^n approaches 0, so the series converges to the limit 3.

(ii) For the series 5/1.2 + 5/2.3 + 5/3.4 + ..., each term can be expressed as 5/(n(n+1)). The nth partial sum, Sn, can be obtained by summing up the terms from the first term to the nth term. In this case, we don't have a geometric series, but we can still find a formula for Sn. By observing the pattern, we can rewrite each term as 5((1/n) - (1/(n+1))). Summing up these terms, we find that Sn = 5((1/1) - (1/2)) + ((1/2) - (1/3)) + ... + ((1/n) - (1/(n+1))). Notice that many terms cancel out, leaving only the first and last terms. Simplifying, we have Sn = 5((1/1) - (1/(n+1))) = 5(1 - 1/(n+1)). As n approaches infinity, 1/(n+1) approaches 0, so the series converges to the limit 5.

Exponential functions are distinct from linear or quadratic functions in many ways. Exponential functions' differences include how they grow and their rate of change. Unlike the linear or quadratic functions, the increase of exponential functions depends on the rate of change and the starting point.

A function is exponential if it has the following characteristics: it has a fixed ratio between consecutive terms, meaning the value of x does not have to be constant; the ratio is constant and equal to the function's base.

Exponential functions, in general, have the form y = abx, where a and b are constants.

Step 1: Determine whether the ratio of consecutive y values is the same.

Step 2: Divide any y value in the table by the previous value to obtain the ratio. If the ratio is constant, the function is exponential.

Step 3: Identify the base by examining the ratio. The base of an exponential function is equal to the ratio of consecutive y values.

I think it would be 6.5 (squared, inches).

If the equal variance assumption (homoskedasticity) does not hold, the least squares (LS) estimators for Bo and B₁ will still be unbiased.

The unbiasedness of LS estimators does not depend on the assumption of homoskedasticity. Unbiasedness implies that, on average, the estimators will produce parameter estimates that are equal to the true population values. This property holds regardless of whether the assumption of equal variance is met or not. However, heteroskedasticity (unequal variance) can affect the efficiency and validity of the estimators. It may lead to inefficient estimates of the standard errors, which can affect the width and accuracy of the confidence intervals. Therefore, while the LS estimators remain unbiased, the assumption of homoskedasticity is important for obtaining accurate and efficient confidence intervals.

Dislike:         5       30       35

Total:          85       84      169

(a) Probability that a person selected at random from this group is an adult who likes the show

The total number of people in the group is 169, and the number of adults who like the show is 50. So the probability is:

Probability = (Number of adults who like the show) / (Total number of people)

Probability = 50/169

Therefore, the probability that a person selected at random from this group is an adult who likes the show is 50/169.

(b) Probability that a person selected at random who likes the show is an adult

The total number of people who like the show = 90

the number of adults who like the show = 50

Probability = (Number of adults who like the show) / (Total number of people who like the show)

Probability = 50/90

Therefore, the probability that a person selected at random who likes the show is an adult is 50/90.

(c) The expected value for the adults who dislike the show

To calculate the expected value, we'll multiply the number of adults who dislike the show (5) by the probability of disliking the show (P(Dislike)):

Expected value = (Number of adults who dislike the show) * (Probability of disliking the show)

Probability of disliking the show = (Number of adults who dislike the show) / (Total number of people)

Probability of disliking the show = 5 / 169

Expected value = 5 * (5 / 169)

Expected value = 25 / 169

Expected value ≈ 0.15 (rounded to two decimal places)

Therefore, the expected value for the adults who dislike the show is approximately 0.15.

(d) Calculate the test statistic.

To calculate the test statistic, we need to perform a chi-square test of independence. The test statistic formula is:

χ² = Σ [(Observed frequency - Expected frequency)² / Expected frequency]

The expected frequencies are calculated by multiplying the row total and column total and dividing by the grand total. Let's calculate the expected frequencies and then calculate the test statistic.

Calculating the test statistic:

χ² = [(50 - (85 * 90) / 169)² / ((85 * 90) / 169)] + [(40 - (84 * 90) / 169)² / ((84 * 90) / 169)] + ... + [(30 - (84 * 35) / 169)² / ((84 * 35) / 169)]

As [K(u): K] is an odd integer, it can be represented as 2n+1, where n ∈ N. So, [K(u²): K] = deg(f(x)) = 1 and K(u) = K(u²).

Given that KCF be a field extension and let u ∈ F such that [K(u): K] is an odd integer.

We are to show that u² is algebraic over K with [K(u²): K] odd and that K(u) = K (u²).

Now consider, K ⊆ K(u²) ⊆ K(u).Thus [K(u²): K] is a factor of [K(u): K].

Therefore, [K(u²): K] is odd. Let f(x) be the minimal polynomial of u over K(u²).

As u ∈ K(u), it means that f(u) = 0.As K ⊆ K(u²), it means that u² ∈ K(u).Hence, there exists an element a ∈ K such that u² = a + bu, where b ∈ K. It follows that u² - a = bu.

Now, squaring both sides, we get u⁴ - 2au² + a² = b²u².Note that LHS is an element of K and RHS is an element of K(u), thus it must be in K. Now u⁴ - 2au² + a² = b²u² ∈ K.(u⁴ - 2au² + a²) - b²u² = 0.

Now let g(x) = x⁴ - 2ax² + a² - b²x = x(x² - a)² - b²x = x(x- √a b)(x+ √a b).Here, g(x) ∈ K[x] and g(u²) = 0.

As g(x) is a polynomial of degree 3 over K(u²), it is also a factor of the minimal polynomial of u² over K(u²).

Since, g(u²) = 0, it means that f(x) is a factor of g(x).Therefore, g(x) = f(x)h(x), for some h(x) ∈ K(u²)[x].

As h(x) is a polynomial in K(u²)[x], it can be written as h(x) = c₀ + c₁x + ... + cₙ xⁿ, where cᵢ ∈ K(u²) and cₙ ≠ 0.

Therefore, g(x) = f(x)(c₀ + c₁x + ... + cₙ xⁿ).Since g(x) is a polynomial of degree 3 over K(u²),

it means that n = 3.If n = 1, then it means that [K(u): K(u²)] = 1, which contradicts the fact that [K(u): K] is odd.

Since n = 3, we have, g(x) = f(x)(c₀ + c₁x + c₂x² + c₃ x³).Since deg(g(x)) = 3, it means that c₃ ≠ 0.So, f(x) must be of degree 1 and it means that u² is algebraic over K and f(x) is its minimal polynomial.

So,  K(u) = K(u²) and [K(u²): K] = deg(f(x)) = 1.

The expression cos³(4x) - sin²(4x) can be rewritten using trigonometric identities to express it solely in terms of cosine functions of linear power.

First, we'll use the identity cos(2θ) = 1 - 2sin²(θ) to rewrite sin²(4x) as 1 - cos²(4x):

cos³(4x) - sin²(4x)

= cos³(4x) - (1 - cos²(4x))

= cos³(4x) - 1 + cos²(4x)

Next, we can use the identity cos(3θ) = 4cos³(θ) - 3cos(θ) to rewrite cos³(4x) as cos(12x):

cos³(4x) - 1 + cos²(4x)

= cos^(3)(4x) - 1 + cos²(4x)

= cos(12x) - 1 + cos²(4x)

Finally, we'll use the Pythagorean identity sin²(θ) + cos²(θ) = 1 to replace cos²(4x) with 1 - sin²(4x):

cos(12x) - 1 + cos²(4x)

= cos(12x) - 1 + (1 - sin²(4x))

= cos(12x) - sin²(4x)

Therefore, the expression cos³(4x) - sin²(4x) can be simplified as cos(12x) - sin²(4x), which is an expression with only cosine functions of linear power.

The value of the integral is 252, which can be expressed as x + iy as 252 + 0i.

Cauchy's Integral Formula states that if f(z) is analytic inside and on a simple closed contour C, and if a is any point inside C, then the nth derivative of f(a) is given by:

f^(n)(a) = (n! / (2πi)) ∫(C) f(z) / (z - a)^(n+1) dz

In this case, we have f(z) = 42/(z + i)^3, and we want to evaluate the integral ∫ f(z) dz over the circle |z + i| = 3.

Applying Cauchy's Integral Formula with n = 2, we have:

f''(a) = (2! / (2πi)) ∫(C) f(z) / (z - a)^3 dz

Since the contour C is the circle |z + i| = 3, we can choose a = -i (as it lies inside the circle). Therefore, we have:

f''(-i) = (2! / (2πi)) ∫(C) f(z) / (z + i)^3 dz

Substituting f(z) = 42/(z + i)^3, we get:

f''(-i) = (2! / (2πi)) ∫(C) (42/(z + i)^3) / (z + i)^3 dz

Simplifying, we have:

f''(-i) = (2! / (2πi)) (42) ∫(C) dz

The integral ∫ dz over the contour C represents the circumference of the circle, which is 2πr, where r is the radius of the circle. In this case, the radius is 3, so the integral simplifies to:

f''(-i) = (2! / (2πi)) (42) (2π * 3)

Simplifying further, we have: f''(-i) = 6 * 42

Therefore, the value of the integral is 252.

The LCM of A, B, and C is the product of all these values 120764100.

To determine the least common multiple (LCM) of A, B, and C, we can use the prime factorization method, which involves multiplying each of the prime factors of A, B, and C the greatest number of times it occurs in any of them. Then, we have to take the product of the highest exponent value from each prime factor.

Example: The prime factorization of 45 is 3² × 5, and the prime factorization of 75 is 3 × 5². Multiplying both gives us the LCM: 3² × 5² = 225. Therefore, the LCM of 45 and 75 is 225.

The steps to find the LCM of A, B, and C using this method are as follows:Firstly, find the prime factorization of A, B, and C.

a) The mean (average) cost of the 10 college math textbooks is $70.3.

b) The median cost of the textbooks is $70.

c) The sample standard deviation of the costs is approximately 1.47.

a) To calculate the mean, we sum up all the textbook costs and divide by the number of textbooks. Adding up the costs: 70 + 72 + 71 + 70 + 69 + 73 + 69 + 68 + 70 + 71 equals 703. Dividing this sum by 10 (the number of textbooks) gives us a mean cost of $70.3.

b) To find the median, we arrange the costs in ascending order: 68, 69, 69, 70, 70, 71, 71, 72, 73. Since there are 10 textbooks, the middle two values are 70 and 71. Therefore, the median cost is $70.

c) To calculate the sample standard deviation, we use the formula that involves finding the difference between each cost and the mean, squaring those differences, summing them up, dividing by the number of textbooks minus 1, and finally taking the square root. The calculations result in a sample standard deviation of approximately 1.47, which represents the average deviation of the textbook costs from the mean.

The equations y = ax + b and y = cx + d, where a < 0, b = 0, c = 0, and d > 0, represent two different types of linear functions. The first equation, y = ax, represents a line passing through the origin with a negative slope.

In the equation y = ax + b, where b = 0, the value of b affects the y-intercept. Since b = 0, the equation simplifies to y = ax, which represents a line passing through the origin (0,0) with a slope determined by the value of a. Since a < 0, the line will have a negative slope. In the equation y = cx + d, where c = 0, the value of c affects the slope of the line. Since c = 0, the equation simplifies to y = d, which represents a horizontal line at a constant value of y. Since d > 0, the line will be positioned above the x-axis.

The differential equation in the form l(y) = g(x) where l is a linear differential operator with constant coefficients is obtained by solving the given differential equation y4 - 27y' = x2 - x.

Given differential equation:y4 - 27y' = x2 - xTo solve the differential equation, let us first make it homogeneous by substituting y = vx: y4 = (vx)4 = v4x4y' = v'x + vx'

Therefore, the given differential equation becomes:v4x4 - 27v'x - 27vx' = x2 - x (Equation 1)Now, we can see that the left-hand side of the above equation can be factorized as (v4 - 27v')x = x2 - x (Equation 2)

The differential equation in the form l(y) = g(x) is l(y) = y4 - 27y' and g(x) = x2 - x.

The explanation for the above equation:

Equation 2 represents a first-order linear differential equation, where the coefficients are constants.

Hence, we can use the integrating factor method to solve this equation.The integrating factor I(x) for the equation v4 - 27v' = 0 can be found out as follows:Coefficients p(x) and q(x) are:p(x) = -27 and q(x) = 0Integrating factor, I(x) = e∫p(x)dx = e-27x

Then, multiplying Equation 2 by I(x) we get:I(x)(v4 - 27v') = x2 - xI(x)v4 - I(x)(27v') = x2 - xI(x)v4 - (I(x)27)v' = x2 - xThis can be written as:d[I(x)v]/dx = x2 - xLet's integrate both sides to get the solution:vI(x) = ∫[x2 - x]dxvI(x) = [x3/3 - x2/2] + C/I(x)Where C is a constant.Now, substituting the value of I(x) = e-27x in the above equation:v(x) = (1/e27x) [x3/3 - x2/2 + C]Therefore, the solution of the given differential equation is:y(x) = (1/e27x) [x3/3 - x2/2 + C]x3/3 - x2/2 + Ce27xy(x) = (x3/3e27x - x2/2e27x + Ce27x)

The number of all subsets of A whose intersection with β has 1 element is n * (n - k) or (n - k) * k.

Given, A is a set such that |A| = n, β is a subset of A and |B| = k.

Let S be a subset of A whose intersection with β has only one element.To find the number of all subsets of A whose intersection with β has 1 element, let's consider two cases:

1. The chosen element belongs to β.2. The chosen element does not belong to β.Case 1:

When we choose an element from β, we have to choose one element out of β and n - k elements out of A - β.So, the total number of such subsets is given byn - k * k

Case 2:When we choose an element that does not belong to β, we have to choose one element out of A - β and k elements out of β.

So, the total number of such subsets is given byn - k * (n - k)

Therefore, the total number of all subsets of A whose intersection with β has only one element is given byn - k * k + n - k * (n - k) = n - k * (k - n + k) = n * (n - k)

For instance, let us consider a simple example to prove this.Let A = {1, 2, 3, 4}, B = {2, 3}, β = {2}.

Therefore, the subsets whose intersection with β has one element are {1, 2}, {4, 2}.

So, the total number of such subsets is 2, which is equal to n * (n - k) = 4 * (4 - 2) = 8.

Hence, the number of all subsets of A whose intersection with β has 1 element is n * (n - k) or (n - k) * k.

we have a = 17, b = 17, and d = 1., the correct relation for this expression is T(n) = Θ(n log n), the growth of T(n) is logarithmic, specifically Θ(n log n).

The given recurrence relation is T(n) = 17 T(n/17) + n, with T(1) = 1. We can solve this using the Master Theorem. To apply the Master Theorem, we need to express the recurrence relation in the form T(n) = a T(n/b) + f(n), where a is the number of recursive subproblems, b is the size of each subproblem, and f(n) is the cost of combining the subproblems. In this case, a = 17 (since we have 17 recursive subproblems), b = 17 (since each subproblem has size n/17), and f(n) = n.

The Master Theorem has three cases. In this case, we have a = 17, b = 17, and d = 1. Comparing d with ㏒ᵇₐ, we see that d = 1 < log¹⁷₁₇= 1.

The optimal solution for the linear programming model is to produce 175 jars of Western Foods Salsa and no jars of Mexico City Salsa. The total profit contribution for this solution is $142.70.

The linear programming model that will enable Salsa R Us to determine the mix of salsa products that will maximize the total profit contribution is given below: Let x = number of jars of Western Foods Salsa produced per production period y = number of jars of Mexico City Salsa produced per production period.

The objective function to maximize total profit contribution is:

Profit = ($1.64 per jar of Western Foods Salsa)x + ($1.93 per jar of Mexico City Salsa)y - ($0.96 per pound of whole tomatoes - 0.10 per jar)x - ($0.64 per pound of tomato sauce - 0.10 per jar)x - ($0.56 per pound of tomato paste - 0.10 per jar)x - $0.05 per jar (which is the sum of the cost of glass jars and labeling and filling costs).

Thus, the objective function is:

Profit = $1.64x + $1.93y - $1.06x - $0.74y - $0.66x - $0.05.

The objective function can be simplified to:

Profit = $0.58x + $1.19y - $0.05

The constraints are as follows:

0.96x + 0.70y ≤ 280 (constraint for whole tomatoes)

For all m and x in R, if m is an integer and x is a real number, then [x] + [2m - x] = 2m + 1. The statement "For all a and b in Z, if a # 0 and b # 0 then ged(a, b) - lcm(a, b) = ab" is false.

Let m be an integer and x be a real number. Then [x] is the greatest integer less than or equal to x, and [2m - x] is the greatest integer less than or equal to 2m - x. Since m is an integer, [2m - x] is also an integer. Therefore, [x] + [2m - x] is an integer.

Now, let y = [x] + [2m - x]. Then y is an integer and y <= 2m. Since x is a real number, there exists a non-integer real number z such that z < x <= z + 1. Therefore, [x] = z and [2m - x] = 2m - z - 1.

Substituting these values for [x] and [2m - x] into the equation y = [x] + [2m - x], we get y = z + (2m - z - 1) = 2m. Therefore, y = 2m + 1.

The statement is false because it is possible for ged(a, b) - lcm(a, b) to be equal to zero. For example, if a = 1 and b = 1, then ged(a, b) = lcm(a, b) = 1, so ged(a, b) - lcm(a, b) = 0.

Another way to disprove the statement is to find a counterexample. A counterexample is an example that shows that the statement is false. For example, the numbers a = 2 and b = 3 are a counterexample to the statement because ged(a, b) - lcm(a, b) = 1 - 6 = -5.
