The integral of the given function e^(6x).cos(5x) is

6/61e6xcos(5x) + 5/61e^6x.sin(5x)+C , c is the constant.

∫u(x)v′(x)dx=u(x)v(x)−∫u′(x)v(x)dx

We apply the integration by parts twice to solve this problem. We use the integration by parts for the first time:

we choose u(x)=cos(5x), v′(x)=e6x, which gives us u(x)=−5sin(5x),  v(x)=16e6x

We have ∫e6xcos(5x)dx = 16e6xcos(5x) + 56∫e6xsin(5x)dx

Now, we use integration by parts for the second time for the integral on the right-hand side. This time

we choose u(x)=sin(5x),v′(x)=e6x, which gives us u′(x)=5cos(5x), v(x)=16e6x

We have ∫e6xsin(5x)dx=16e6xsin(5x)+56∫e6xcos(5x)dx

Evaluating the integral:

∫e6xcos(5x)dx=16e6xcos(5x)+56∫e6xsin(5x)dx=16e6xcos(5x)+56(16e6xsin(5x)−56∫e6xcos(5x)dx)=16e6xcos(5x)+536e6xsin(5x)−2536∫e6xcos(5x)dx

We solve this equation for ∫e6xcos(5x)dx , and we get:

∫e^6x.cos^(5x).dx = 6/61e6xcos(5x) + 5/61e^6x.sin(5x)+C

where C is the constant of integration.

Based on the quadrilateral, the measure of angles a, b, c, and d are as follows;

In Mathematics, the measure of the sum of two (2) adjacent angles would be equal to 180º when two (2) parallel lines are cut through by a transversal according to the Linear Pair Postulate:

a + 79° = 180°

a = 180° - 79°

a = 101°

In Geometry, the vertical angles theorem states that two opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other. Therefore, we have the following:

c = 83° (vertically opposite angle).

By applying the co-interior angles theorem, we have the following:

a + b = 180°

101 + b= 180°

b = 180° - 101°

b = 79°

d + c = 180° (co-interior angles)

d + 83° = 180°

d = 180° - 83°

d = 97°

If a normal population has a known variance σ² ,  then the value of confidence level for z_(α/2) equal to 2.10 is 96.42% .

The value of z_(α/2) is used to determine the critical value for a two-tailed hypothesis test with a given level of significance(α).

The Critical Value separates the rejection region from the acceptance region in the standard normal distribution.

A Confidence Level is often expressed as (1 - α) , where α is the level of significance.

To find the confidence level that corresponds to z_(α/2) = 2.10, we can solve for 1 - α:

⇒ α/2  = 0.0179 ;

⇒ α = 0.0179 × 2 = 0.0358 ;

⇒ So , 1 - α = 1 - 0.0358 = 0.9642 or 96.42% .

Therefore , the value of Confidence Level is 96.42% .

The vectors =−6 3 and = 6 6 are not orthogonal because they have different magnitude.

Orthogonal vectors are two vectors that are perpendicular to each other, meaning they form a 90-degree angle.

As we all know that when two vectors have the same magnitude and are orthogonal, they are said to be orthonormal.

To find all numbers and for which the vectors =−6 3 and = 6 6 are orthogonal and have the same magnitude, we first need to find the magnitude of each vector.

For the first vector, =−6 3,

the magnitude is

=> √(−6)² + (3)²

=>  √(36 + 9) = √45

=> 3√5.

For the second vector, = 6 6,

When Luke selects combinations of x1 and x2 that, function given his income and the prices of x1 and x2, maximise his utility, his utility is maximised.

A utility function, which gauges the satisfaction he will have from a particular mix of items, can be used to model Luke's decision-making. His utility function, for instance, might be u(x1,x2)=x1 x2, which indicates the satisfaction he will experience from x1 and x2 is the sum of their respective numbers. His income is m, and the prices of x1 and x2 are represented as p1 and p2, respectively. Given Luke's income and the prices of x1 and x2, the x1 and x2 combination that maximises Luke's utility will also maximise the product of x1 and x2. This is so that, given the same income and prices, if one combination of x1 and x2 gives a higher utility than another combination of x1 and x2, Luke will then pick the combo that has the greatest utility. Given his income and the costs of x1 and x2, Luke will therefore go for the x1 and x2 combination that provides him with the greatest utility.

Length is the term used for identifying the size of an object or distance from one point to the other.

The length of KL can be found using the distance formula between two points:

√((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of the two points.

So, the length of KL is:

√((-9 - 8)^2 + (5 + 1)^2) = √((-17)^2 + 6^2) = √(289 + 36) = √(325) = 18.03.

A linear equation is an algebraic equation with simply a constant and a first-order (linear) component of the form y=mx+b, where m is the slope and b is the y-intercept. The above is sometimes referred to as a "linear equation with two variables," where y and x are the variables.

Ax+By=C is the typical form for linear equations in two variables. 2x+3y=5, for example, is a simple linear equation. It is rather simple to get both intercepts when an equation is stated in this way (x and y).

Let's call the number of minutes passed "t".

The total number of sticks in the wood pile after t minutes is given by the equation:

Woodpile = 5 + 7t - 3t = 5 + 4t

We want to find the time t it takes for the wood pile to have 45 sticks:

The total number of matches played are 6 matches.

The number of matches in a round-robin tournament is given by n(n-1)/2, where n is the number of teams.

In this case, n=4, so the number of matches = 4(4-1)/2 = 6.

The formula n(n-1)/2 is a combinatorial calculation for the number of unique pairings possible among n items.

In the context of a round-robin tournament, n is the number of teams, and each team must play every other team exactly once. This means that each match must involve two unique teams.

The formula n(n-1)/2 calculates the number of unique pairs that can be formed from n items. The numerator (n-1) represents the number of elements available to be paired with the first element, then n-2 for the second element and so on. Dividing by 2 accounts for double-counting the same pairs, as each pair can be counted twice (once for each team in the pair).

The total atomic masses of a compound's constituent atoms, expressed in grams per mole, make up the compound's molar mass.

You must adhere to the grams to moles formula in order to accurately calculate the number of moles, n, of a substance with a given mass, m, (in grams): The molar mass of this substance is M, and n = m / M.

The atomic mass of an element is multiplied by the number of its atoms. Add the values once you've completed this for all the atoms to determine the amount of grams in a mole.

A compound's molar mass is determined by adding the atomic masses of all of its constituent atoms together in grams per mole.

Answer:
the value of a3 is 39.

Step-by-step explanation:

The given equation is a recursive formula for the sequence a(n) = 4a(n-1) - 1 - 4. This means that a(n) is defined in terms of the previous term in the sequence, a(n-1).

Given that a1 = 3, we can use this as the starting point and apply the recursive formula repeatedly to find the value of a3.

a2 = 4a1 - 1 - 4 = 4(3) - 1 - 4 = 11

a3 = 4a2 - 1 - 4 = 4(11) - 1 - 4 = 39

So the value of a3 is 39.

Answer:

28

Explanation:

Given that a1 = 3 and an = 4an-1 - 4

to find a3 we can substitute the value of a3 in terms of a2 and a1.

a3 = 4a2 - 4

and a2 = 4a1 - 4

substituting a2 and a1 in terms of their values we get

a3 = 4(4a1 - 4) - 4

substituting the given value of a1 we get

a3 = 4(4*3 - 4) - 4

a3 = 4(8) - 4 = 32 - 4 = 28

So the value of a3 is 28.
