The limit is -1/4.

Using Squeeze Theorem, we can conclude that lim x² cos(1/x²) = 0 as x approaches 0.

To compute the limit lim (2+h)^(-1) - 2^(-1) / h as h approaches 0, we can simplify the expression:

lim (2+h)^(-1) - 2^(-1) / h

= (1/(2+h) - 1/2) / h

Now, let's find the common denominator and simplify further:

= [(2 - (2+h)) / (2(2+h))] / h

= (-h / (2(2+h))) / h

= -1 / (2(2+h))

Finally, we can take the limit as h approaches 0:

lim -1 / (2(2+h)) = -1 / (2(2+0)) = -1 / (2(2)) = -1/4

Therefore, the limit is -1/4.

Now, let's use the Squeeze Theorem to show that lim x² cos(1/x²) = 0 as x approaches 0.

We know that -1 ≤ cos(1/x²) ≤ 1 for all x ≠ 0.

Multiplying through by x², we have -x² ≤ x² cos(1/x²) ≤ x².

Taking the limit as x approaches 0, we get:

lim -x² ≤ lim x² cos(1/x²) ≤ lim x²

As x approaches 0, both -x² and x² approach 0.

Therefore, by the Squeeze Theorem, we can conclude that lim x² cos(1/x²) = 0 as x approaches 0.

The given angle is 8° 55' 42". To convert this angle to decimal degrees, we need to convert the minutes and seconds to their decimal equivalents. The resulting angle will be in decimal degrees.

To convert the minutes and seconds to their decimal equivalents, we divide the minutes by 60 and the seconds by 3600, and then add these values to the degrees. In this case, we have:

8° + (55/60)° + (42/3600)°

Simplifying the fractions, we have:

8° + (11/12)° + (7/600)°

Combining the terms, we get:

8° + (11/12)° + (7/600)° = (8*12 + 11 + 7/600)° = (96 + 11 + 0.0117)° = 107.0117°

The given equation represents the Fundamental Theorem of Calculus, which provides a fundamental connection between the definite integral and the antiderivative of a function.

The given expression represents the equation of the Fundamental Theorem of Calculus, stating that the definite integral of a function f(x) with respect to x over the interval [a, b] is equal to the antiderivative of f(x) evaluated at b minus the antiderivative of f(x) evaluated at a. This theorem allows us to calculate definite integrals by evaluating the antiderivative of the integrand function at the endpoints. The Fundamental Theorem of Calculus relates the definite integral of a function to its antiderivative. The equation can be written as:

∫[a, b] f(x) dx = F(b) - F(a)

where F(x) is the antiderivative (or indefinite integral) of f(x).

The left-hand side of the equation represents the definite integral of f(x) with respect to x over the interval [a, b]. It calculates the net area under the curve of the function f(x) between the x-values a and b. The right-hand side of the equation involves evaluating the antiderivative of f(x) at the endpoints b and a, respectively. This is done by finding the antiderivative of f(x) and plugging in the values b and a. Subtracting the value of F(a) from F(b) gives us the net change in the antiderivative over the interval [a, b]. The equation essentially states that the net change in the antiderivative of f(x) over the interval [a, b] is equal to the area under the curve of f(x) over that same interval.

The two positive numbers that satisfy the given conditions are 20 and 20.

How to minimize an expression?

To minimize an expression, you typically need to find the value or values of the variables that result in the smallest possible value for the expression.

Let's assume the two positive numbers as x and y. We are given that their product is 400, so we have the equation xy = 400.

To find the values of x and y that minimize the expression 2x + 3y, we can use the concept of the arithmetic mean-geometric mean inequality (AM-GM inequality). According to the inequality, the arithmetic mean of two positive numbers is always greater than or equal to their geometric mean.

In this case, the arithmetic mean of x and y is (x + y)/2, and the geometric mean is √(xy). So, applying the AM-GM inequality, we have:

(x + y)/2 ≥ √(xy)

Plugging in xy = 400, we get:

(x + y)/2 ≥ √400

(x + y)/2 ≥ 20

To minimize the expression 2x + 3y, we want the values of x and y to be as close as possible. The equality condition of the AM-GM inequality holds when x = y, so we can choose x = y = 20.

When x = y = 20, the product xy is 400, and the expression 2x + 3y becomes 2(20) + 3(20) = 40 + 60 = 100. This gives us the minimum sum for twice the first number plus three times the second number.

If a convex polygon has three angles whose sum is 180°, then the polygon must be a triangle.

Let's assume we have a convex polygon with more than three angles whose sum is 180°. If it is not a triangle, it must have at least one additional angle. Let's call the sum of the three angles forming 180° as A and the additional angle as B.

Now, let's consider the sum of the angles in the polygon. For any polygon with n sides, the sum of its interior angles is given by (n-2) * 180°. Since our polygon has three angles summing up to 180° (A), the sum of its remaining angles (excluding the three angles) must be (n-3) * 180°.

Now, let's compare the two sums: (n-2) * 180° vs. (n-3) * 180° + B.

We can see that (n-3) * 180° + B is greater than (n-2) * 180° because it has an additional angle B. However, this contradicts the fact that the sum of the angles in a convex polygon is fixed at (n-2) * 180°. Hence, our assumption that the polygon has more than three angles forming 180° must be false. Therefore, if a convex polygon has three angles whose sum is 180°, it must be a triangle.

To evaluate the double integral, we need to carefully select the order of integration. Let's consider the given function and limits of integration:

Answer :  the double integral ∬R (6y + 7xy) dA, where R: 0 ≤ x ≤ 5, -1 ≤ y ≤ 1, evaluates to 0.

∬R (6y + 7xy) dA

where R represents the region defined by the limits:

R: 0 ≤ x ≤ 5, -1 ≤ y ≤ 1

To determine the appropriate order of integration, we can consider the integrals with respect to each variable separately and choose the order that simplifies the calculations.

Let's start by integrating with respect to y first:

∫∫R (6y + 7xy) dy dx

Integrating (6y + 7xy) with respect to y gives:

∫ (3y^2 + 7xy^2/2) | -1 to 1 dx

Simplifying further, we have:

∫ (3 + 7x/2) - (3 + 7x/2) dx

The terms with y have been eliminated, and we are left with an integral with respect to x only.

Now, we can integrate with respect to x:

∫ (3 + 7x/2 - 3 - 7x/2) dx

Integrating (3 + 7x/2 - 3 - 7x/2) with respect to x gives:

∫ 0 dx

The integral of a constant is simply the constant times the variable:

0x = 0

Therefore, the value of the double integral is 0.

In summary, the double integral ∬R (6y + 7xy) dA, where R: 0 ≤ x ≤ 5, -1 ≤ y ≤ 1, evaluates to 0.

Answer:

  47

Step-by-step explanation:

Given 3 persons per horse, 4 sheep per cow, 3 ducks per person, you want to know if the total number of people, horses, sheep, cows, and ducks can be any of 41, 47, 59, 61, or 66.

Using {d, p, h, s, c} for numbers of {ducks, people, horses, sheep, cows}, the given ratios are ...

We can combine the first and last of these to d : p : h = 9 : 3 : 1.

In terms of horses, the total number of horses, people, and ducks will be ...

  h(1 + 3 + 9) = 13h

In terms of cows, the total number of sheep and cows will be ...

  c(1 + 4) = 5c

Then the total Hamlet population will be (13h +5c).

We need to find the number on the given list that cannot be expressed as this sort of sum.

In the attachment, we do that by subtracting multiples of 13 from the offered choice, and seeing if any remainders are divisible by 5. The cases where subtracting a multiple of 13 gives a multiple of 5 are highlighted.

Only 47 cannot be a total of people, horses, sheep, cows, and ducks.

Based on the above analysis, the numbers that could not possibly be the total number of people, horses, sheep, cows, and ducks in Hamlet are: 41, 47, 59, and 61.

To determine which of the given numbers could not possibly be the total number of people, horses, sheep, cows, and ducks in Hamlet, we need to check if they satisfy the given ratios between these animals and people.

Given ratios:

3 people for each horse

4 sheep for each cow

3 ducks for each person

Let's evaluate each option:

a) 41:

To satisfy the ratios, the number of horses would need to be a multiple of 3. However, 41 is not divisible by 3, so it is not possible.

b) 47:

Again, the number of horses would need to be a multiple of 3 to satisfy the ratios. 47 is not divisible by 3, so it is not possible.

c) 59:

Similarly, 59 is not divisible by 3, so it is not possible.

d) 61:

Once again, 61 is not divisible by 3, so it is not possible.

e) 66:

In this case, the number of horses would be 66 / 3 = 22. If we have 22 horses, we would need 22 * 3 = 66 people, which satisfies the ratio. However, we also need to check the other ratios. If we have 22 horses, we would need 22 * 4 = 88 sheep and 66 * 3 = 198 ducks. The number of cows can be any number since there is no ratio involving cows. Therefore, 66 is possible as the total number.

To determine the convergence or divergence of the series, we can examine the behavior of its terms as n approaches infinity. In this case, we have the expression 5n + 18 / (n(n + 9)).

As n grows larger, the dominant term in the numerator becomes 5n, while the dominant term in the denominator becomes n^2. Therefore, we can simplify the expression to 5n / n^2.

Now, we can rewrite this as 5/n, which approaches zero as n tends to infinity. However, for a series to be convergent, the terms must approach zero, which is not the case here. The series diverges since the terms do not converge to zero.

In summary, the given vectors a and b have the following properties: their dot product is 0, the magnitude of vector b is √30, the dot product of vector b and vector a is 0, the dot product of vector a and vector b is 0, and the cross product of vectors a and b is <-3, -4, 9>.

To find the dot product of two vectors, we multiply their corresponding components and then sum the results. In this case, a • b = (5 * 5) + (1 * 1) + (-2 * -2) = 25 + 1 + 4 = 30, which equals 0.

To find the magnitude of a vector, we take the square root of the sum of the squares of its components. The magnitude of vector b, denoted as ||b||, is √((5^2) + (1^2) + (-2^2)) = √(25 + 1 + 4) = √30.

The dot product of vector b and vector a, denoted as b • a, can be found using the same formula as before. Since the dot product is a commutative operation, it yields the same result as the dot product of vector a and vector b. Therefore, b • a = a • b = 0.

The cross product of two vectors, denoted as a × b, is a vector perpendicular to both a and b. It can be calculated using the cross product formula. In this case, the cross product of vectors a and b is given by the determinant:

We can simplify the first integral using a change of variable, u = t/7, dt = 7du, which gives:

g(7x) = ∫7du 13 x € (0, x) + ∫dt 13 7x € (7x, [infinity])

We can simplify the first integral further:

g(7x) = 7∫du 13 x € (0, x) + ∫dt 13 7x € (7x, [infinity])

We can now substitute g(x) + C for the second integral:

g(7x) = 7∫du 13 x € (0, x) + g(x) + C

Finally, we can simplify the first integral using a change of variable, v = u/7, du = 7dv, which gives:

g(7x) = ∫7dv 13 x/7 € (0, x/7) + g(x) + C

g(7x) = g(x/7) + g(x) + C

Therefore, g(7x) = g(x) + C for all x in (0, [infinity]).

f(1) represents the value of the function f(x) at x = 1. In this case, f(1) = 3, which means that when x is 1, the value of the function is 3.

What is Derivative?

In mathematics, the derivative is a way of showing the rate of change: that is, the amount by which a function changes at one given point. For functions that act on real numbers, it is the slope of the tangent line at a point on the graph.

To find the derivative of the function f(x) = 6x / (x² + 1), we can use the quotient rule. The quotient rule states that if we have a function u(x) = g(x) / h(x), then the derivative of u(x) with respect to x is given by:

u'(x) = (g'(x)h(x) - g(x)h'(x)) / (h(x))²

In this case, g(x) = 6x and h(x) = x² + 1. Let's differentiate g(x) and h(x) to apply the quotient rule:

g'(x) = 6

h'(x) = 2x

Now we can apply the quotient rule:

f'(x) = (g'(x)h(x) - g(x)h'(x)) / (h(x))²

= (6(x² + 1) - 6x(2x)) / (x² + 1)²

= (6x² + 6 - 12x²) / (x² + 1)²

= (-6x² + 6) / (x² + 1)²

Now, let's evaluate f(1) and f'(1):

To find f(1), we substitute x = 1 into the original function:

f(1) = 6(1) / (1² + 1)

= 6 / 2

= 3

To find f'(1), we substitute x = 1 into the derivative we just found:

f'(1) = (-6(1)² + 6) / (1² + 1)²

= 0 / 4

= 0

Interpretation:

f(1) represents the value of the function f(x) at x = 1. In this case, f(1) = 3, which means that when x is 1, the value of the function is 3.

f'(1) represents the instantaneous rate of change of the function f(x) at x = 1. In this case, f'(1) = 0, which means that at x = 1, the function has a horizontal tangent, and its rate of change is zero at that point. This indicates a possible extremum or a point of inflection.

Overall, f(1) represents the value of the function at a specific point, while f'(1) represents the rate of change of the function at that point.

If the population continues to grow at a rate of 3% per year, it will be approximately 195 people in ten years. It takes approximately 24 years for the population to at least double if the growth rate remains constant.

Explanation: The formula for exponential growth can be expressed as P(t) = P0 * [tex](1+r)^{t}[/tex], where P(t) represents the population at time t, P0 is the initial population, r is the growth rate per time period, and t is the number of time periods. In this case, the initial population P0 is 150, and the growth rate r is 3% or 0.03. Therefore, the formula for the population as a function of time is P(t) = 150 *[tex](1 + 0.03)^{t}.[/tex]

To find the population in ten years, we substitute t = 10 into the formula: P(10) = 150 * [tex](1 + 0.03)^{10}[/tex]. Evaluating this expression gives us P(10) ≈ 195. Thus, if the population continues to grow at a rate of 3% per year, it will be approximately 195 people in ten years.

To determine the number of full years it takes to at least double the population, we need to find the value of t when P(t) = 2 * P0. In this case, P0 is 150. So, we set up the equation 2 * 150 = 150 * [tex](1 + 0.03)^{t}[/tex] and solve for t. Simplifying the equation, we get 2 = [tex](1 + 0.03)^{t}[/tex]. Taking the natural logarithm of both sides, we have ln(2) = t * ln(1 + 0.03). Dividing both sides by ln(1 + 0.03), we find t ≈ ln(2) / ln(1.03) ≈ 23.45. Therefore, it takes approximately 24 years for the population to at least double if the growth rate remains constant.

The value of (10) based on the function h(x) = 6) can be found by substituting x = 10 into the function. The answer is (10) = 6.

The given function is h(x) = 6. To find the value of (10) based on this function, we substitute x = 10 into the function and evaluate it. Therefore, (10) = h(10) = 6.

In this case, the function h(x) is a constant function, where the output value is always 6, regardless of the input value. So, when we substitute x = 10 into the function, the result is 6. Thus, we can conclude that (10) = 6 based on the given function h(x) = 6.

It's worth noting that the notation used here, (10), might suggest a function with a variable or a placeholder. However, since the given function is a constant function, the value of (10) remains the same regardless of the input value, and it is equal to 6.
