The integrating factor of the given differential equation is I(t) = e^(sin(t)).

To find the integrating factor of the given differential equation, dy/dx = -cos(t)y t^2, follow these steps:

Rewrite the differential equation in the standard form:
(dy/dx) + P(t)y = Q(t), where P(t) and Q(t) are functions of t.

In our case, P(t) = cos(t) and Q(t) = -t^2.

Calculate the integrating factor, I(t), using the formula:
I(t) = e^(∫P(t) dt)

Here, P(t) = cos(t), so we need to integrate cos(t) with respect to t.

3. Integrate cos(t) with respect to t:
∫cos(t) dt = sin(t) + C, where C is the constant of integration. However, since we only need the function part for the integrating factor, we can ignore the constant C.

4. Substitute the integration result into the integrating factor formula:
I(t) = e^(sin(t))

So, the integrating factor of the given differential equation is I(t) = e^(sin(t)).

In both the cases when n is even and when n is odd, the expression is odd, we can conclude that if n ∈ Z, then [tex]5n^2 + 3n + 7[/tex]is odd.

To prove the proposition "if n ∈ Z, then[tex]5n^2 + 3n + 7[/tex]is odd" using a direct proof with cases, we consider two cases: when n is even and when n is odd.

Case 1: n is even.

Assume n = 2k, where k ∈ Z. Substituting this into the expression, we have [tex]5(2k)^2 + 3(2k) + 7 = 20k^2 + 6k + 7[/tex]. Notice that [tex]20k^2[/tex] and 6k are both even since they can be factored by 2. Adding an odd number (7) to an even number results in an odd number. Hence, the expression is odd when n is even.

Case 2: n is odd.

Assume n = 2k + 1, where k ∈ Z. Substituting this into the expression, we have [tex]5(2k + 1)^2 + 3(2k + 1) + 7 = 20k^2 + 16k + 15[/tex]. Again, notice that [tex]20k^2[/tex]and 16k are even. Adding an odd number (15) to an even number results in an odd number. Therefore, the expression is odd when n is odd.

Since we have covered all possible cases and in each case, the expression is odd, we can conclude that if n ∈ Z, then 5n^2 + 3n + 7 is odd.

The correct expressions which model the value of the phone after t years are given by 300(0.87)t/12 and 300(0.9885)t. Value of a cellular phone depreciates at a rate of 13% every month.

Given a cellular phone's value depreciates at a rate of 13% every month. So, the phone's value will decrease by 13% of its original value every month. Therefore, the equation for the phone's value after t years is given by:

V(t) = $300 × (1 - 0.13)ᵗ, where t is the time in years.

The given expressions, 300(0. 87)/12 and 300(0. 1880)t 300(0. 87)t/12 and 300(0. 9885)t 300(0. 87)124 and 300(0. 1880)t 300(0. 87) 12 and 300(0. 9885)t. Do not model the value of the phone after t years. Therefore, the correct answer is 300(0. 87)t/12 and 300(0. 9885)t.

The value of a cellular phone depreciates at a rate of 13% every month, which means that the remaining value of the phone after one month is 87% of the original value. Therefore, to calculate the value after t years, the equation

V(t) = $300 × (1 - 0.13)ᵗ should be used.

By plugging in the time t in years, we can get the remaining value of the phone. The first option (300(0.87)/12 must be corrected because it only calculates the phone's value after one month, which is not the question asked. Therefore, the correct expression that model the phone's value after t years is given by 300(0.87)t/12 and 300(0.9885)t.

The null and alternative hypotheses are: H0: σ21 = σ22 and Ha: σ21 ≠ σ22(C).

To find the critical value, we need to use the F-distribution with degrees of freedom (df1 = n1 - 1, df2 = n2 - 1) at a significance level of α/2 = 0.005 (since this is a two-tailed test).

Using a calculator or a table, we find that the critical values are F0.005(12,7) = 4.963 (for the left tail) and F0.995(12,7) = 0.202 (for the right tail).

The test statistic is calculated as F = s21/s22, where s21 and s22 are the sample variances and n1 and n2 are the sample sizes. Plugging in the given values, we get F = 5.7^2/5.1^2 = 1.707.

Since this value is not in the rejection region (i.e., it is between the critical values), we fail to reject the null hypothesis. Therefore, we do not have sufficient evidence to claim that the population variances are different at the 0.01 level of significance.

the point on the hyperboloid where the tangent plane is parallel to the plane z = 6x + 6y is (3, -3, 1/2).

To find the points on the hyperboloid where the tangent plane is parallel to the plane z = 6x + 6y, we need to first find the gradient vector of the hyperboloid at any point (x, y, z) on the hyperboloid.

The gradient of x^2 - y^2 - z^2 = 9 is given by:

grad(x^2 - y^2 - z^2 - 9) = (2x, -2y, -2z)

Now, we need to find the points on the hyperboloid where the gradient vector is parallel to the normal vector of the plane z = 6x + 6y, which is given by (6, 6, -1).

Setting the components of the gradient vector and the normal vector equal to each other, we get the following system of equations:

2x = 6

-2y = 6

-2z = -1

Solving for x, y, and z, we get:

x = 3

y = -3

z = 1/2

So, the point on the hyperboloid where the tangent plane is parallel to the plane z = 6x + 6y is (3, -3, 1/2).

To verify that the tangent plane is parallel to the given plane, we can find the gradient of the hyperboloid at this point, which is (6, 6, -1), and take the dot product with the normal vector of the given plane, which is (6, 6, -1). The dot product is equal to 72, which is nonzero, so the tangent plane is parallel to the given plane.

a. By using the recursive relation a₃ = 4, a₄ = 8, and a₅ = 16.  b. By assuming values and using mathematical induction proved aₙ = 2n-1 for all n ∈ ℕ.

a. Using the given recursive relation, we can calculate the values of a₃, a₄, and a₅ as follows:

a₃ = a₂ + 2a₁ = 2 + 2(1) = 4

a₄ = a₃ + 2a₂ = 4 + 2(2) = 8

a₅ = a₄ + 2a₃ = 8 + 2(4) = 16

Therefore, a₃ = 4, a₄ = 8, and a₅ = 16.

b. To prove the statement by Strong principle of mathematical induction, we must first establish a base case. From the given recursive relation, we have a₁ = 1 = 2¹ - 1, which satisfies the base case.

Now, assume that the statement is true for all values of k less than or equal to some arbitrary positive integer n. That is, assume that aₓ = 2x-1 for all x ≤ n.

We must show that this implies that aₙ = 2n-1. To do this, we can use the given recursive relation:

aₙ = aₙ-1 + 2aₙ-2

Substituting the assumption for aₓ into this relation, we get:

aₙ = 2n-2 + 2(2n-3)

aₙ = 2n-2 + 2n-2

aₙ = 2(2n-2)

aₙ = 2n-1

Therefore, assuming the statement is true for all values less than or equal to n implies that it is also true for n+1. By the principle of mathematical induction, we can conclude that the statement is true for all positive integers n.

Hence, we have proved that aₙ = 2n-1 for all n ∈ ℕ.

The average answer time for the entire day on Monday was 15.9 seconds.

For the average answer time for the entire day on Monday, we need to calculate the total time spent answering calls and divide by the total number of calls answered.

Let's first calculate the total time spent answering calls:

- For the 500 calls before noon, the total time spent answering calls is: 500 x 16 = 8,000 seconds

- For the 350 calls from noon to 6pm, the total time spent answering calls is: 350 x 14 = 4,900 seconds

- For the 150 calls on Monday night, the total time spent answering calls is: 150 x 20 = 3,000 seconds

So the total time spent answering calls on Monday is:

8,000 + 4,900 + 3,000 = 15,900 seconds

Now, let's calculate the total number of calls answered:

500 + 350 + 150 = 1,000 calls

Finally, we can calculate the average answer time for the entire day on Monday:

Average answer time = Total time spent answering calls / Total number of calls answered

= 15,900 / 1,000

= 15.9 seconds

Therefore, the average answer time for the entire day on Monday was 15.9 seconds.

The distance from the plane 10x y z=90 to the plane 10x y z=70, we need to find the distance between a point on one plane and the other plane. The distance from the plane 10x y z=90 to the plane 10x y z=70 is 10sqrt(2) units.

Take the point (0,0,9) on the plane 10x y z=90.
The distance between a point and a plane can be found using the formula:
distance = | ax + by + cz - d | / sqrt(a^2 + b^2 + c^2)
where a, b, and c are the coefficients of the x, y, and z variables in the plane equation, d is the constant term, and (x, y, z) is the coordinates of the point.
For the plane 10x y z=70, the coefficients are the same, but the constant term is different, so we have:
distance = | 10(0) + 0(0) + 10(9) - 70 | / sqrt(10^2 + 0^2 + 10^2)
distance = | 20 | / sqrt(200)
distance = 20 / 10sqrt(2)

The statement that correctly compares the two functions is B, They have the same y-intercept but different end behavior.

From the graph that the exponential function passes through the points (-0.5, 8), (0, 4), (1, 1), and (5, 0). Use this information to find the equation of the exponential function.

Assume that the exponential function has the form f(x) = a × bˣ, where a and b = constants to be determined, use the points (0, 4) and (1, 1) to set up a system of equations:

f(0) = a × b⁰ = 4

f(1) = a × b¹ = 1

Dividing the second equation by the first:

b = 1/4

Substituting this value of b into the first equation:

a = 4

So the equation of the exponential function is f(x) = 4 × (1/4)ˣ = 4 × (1/2)²ˣ.

Now, compare the two functions. Since the exponential function has a y-intercept of 4, and the equation of the other function is not given.

However, from the graph that the exponential function approaches the x-axis (i.e., has an end behavior of approaching zero) as x gets larger and larger. Therefore, the exponential function and the other function have different end behavior.

Lower bound: If we round each side down to the nearest centimeter, we get a rectangular parallelepiped with sides 2 cm, 3 cm, and 4 cm. The volume of this parallelepiped is 2 cm * 3 cm * 4 cm = 24 cm³.

Upper bound: If we round each side up to the nearest centimeter, we get a rectangular parallelepiped with sides 4 cm, 5 cm, and 6 cm. The volume of this parallelepiped is 4 cm * 5 cm * 6 cm = 120 cm³.

Therefore, the best lower bound for the volume is 24 cm³, and the best upper bound is 120 cm³.

b. Similar to the volume, we can determine the best upper and lower bounds for the surface area of the parallelepiped by considering the extreme cases.

Lower bound: If we round each side down to the nearest centimeter, the dimensions of the parallelepiped become 2 cm, 3 cm, and 4 cm. The surface area is calculated as follows:

CH3OH → CH4 + 1/2O2

By comparing the standard enthalpies of formation (∆Hf) for each compound involved, we can determine the overall enthalpy change of the reaction. The standard enthalpy of formation for wood alcohol (∆Hf(CH3OH)) is known to be negative, indicating its formation is exothermic. However, the standard enthalpy of formation for methane (∆Hf(CH4)) is more negative than the sum of ∆Hf(CH3OH) and 1/2∆Hf(O2).

This means that the formation of methane and oxygen from wood alcohol would require an input of energy, making it thermodynamically unfavorable at 25°C and 1 atm. Therefore, under these conditions, the decomposition of wood alcohol to methane and oxygen would not occur spontaneously.

[tex]\frac{12}{5}[/tex] = [tex]\frac{1}{6k}[/tex] ( cross- multiply )

72k = 5 ( divide both sides by 72 )

k = [tex]\frac{5}{72}[/tex]

Answer: k=8.4 or 42/5

Step-by-step explanation: to find k you take 1 2/5 and divide it by 1/6. When I did it I got 8.4. To check my work I replaced the variable in the equation and it was correct.

Mr. Baral has to pay Rs 64000 as an annual income tax at an interest of 10% for his stationary shop.

From the question, we have given that if he is unmarried and his income is between Rs 5,00,001 to Rs 7,00,000, he has to pay an annual interest of 10%.

Given annual income in Rs = 640000.

The annual income tax rate he has to pay at = 10%

So, to find out the income tax from the annual income we have to find out the 10% of 640000.

Income tax = 640000/100 * 10 = 64000

From the above analysis, we can conclude that Mr. Baral has to pay 64000 rs of income tax annually.

The normal distribution tails never go up again after crossing the horizontal axis. In a normal distribution, the tails of the curve represent the extreme values in either direction.

The tails of the curve extend infinitely in both directions and they get closer and closer to the horizontal axis, but they never touch it.

The curve is symmetrical around the mean and the area under the curve is equal to 1 or 100%.In probability theory, normal distribution is a continuous probability distribution that describes a set of random variables, and is often referred to as the Gaussian distribution. It is a bell-shaped curve and is characterized by the mean and standard deviation. It is an important concept in statistics and is used to describe various natural phenomena, such as heights, weights, IQ scores, etc.

TRUE. The visual inspection method is a simple and quick way to get a rough idea of the cash inflows and outflows of a business.

However, it does not provide any supporting documentation for the statement of cash flows, nor does it provide any detailed information on the sources and uses of cash.

The statement of cash flows is a financial statement that reports the cash inflows and outflows of a business during a given period of time. It is an essential tool for analyzing a company's financial performance and assessing its ability to generate cash. The statement of cash flows should provide a clear and detailed picture of the cash inflows and outflows of the business, and should be supported by appropriate documentation.

While the visual inspection method may be useful as a preliminary tool for assessing a company's cash flows, it should not be relied upon as the sole source of information for preparing the statement of cash flows. Instead, a more rigorous and detailed analysis should be undertaken, based on the company's accounting records and supporting documentation.

This will ensure that the statement of cash flows is accurate, reliable, and informative, and will enable investors and other stakeholders to make informed decisions based on the company's financial performance.

The derivative of h(x) with respect to x, evaluated at x = 5, is h'(5) = 13.

To find h'(5) if h(x) = r(x) s(x), we need to differentiate the function h(x) with respect to x and evaluate it at x = 5.

Using the product rule, we differentiate h(x) as follows:

h'(x) = r'(x) s(x) + r(x) s'(x)

Now, let's substitute the given values into the equation:

r(5) = 4, s(5) = 3, r'(5) = -1, and s'(5) = 4.

h'(x) = r'(x) s(x) + r(x) s'(x)

h'(5) = r'(5) s(5) + r(5) s'(5)

Plugging in the values, we get:

h'(5) = (-1)(3) + (4)(4)

h'(5) = -3 + 16

h'(5) = 13

Therefore, the derivative of h(x) with respect to x, evaluated at x = 5, is h'(5) = 13.

In simpler terms, h'(5) represents the rate of change of the function h(x) at x = 5. In this case, h(x) is the product of two functions, r(x) and s(x). By applying the product rule, we differentiate each function and multiply them together. Substituting the given values, we find that h'(5) equals 13. This means that at x = 5, the function h(x) is changing at a rate of 13 units per unit change in x.
