The formula is true for all positive integers n.

The formula to verify that for all n ≥ 1, the sum of the squares of the first 2n positive integers is given by the formula is as follows :1² + 2² +3²+...+(2n)² =n(2n + 1)(4n+1)/ 3

To prove this formula is true for all n greater than or equal to 1, we need to use the mathematical induction method.

Base case:

Let's assume that n= 1. Then,1² + 2²=1(2(1)+1)(4(1)+1)/ 3=5/3Therefore, the formula is correct for the initial case (n=1).

Induction Hypothesis:

Suppose that the formula is true for all integers 1≤ k ≤ n. That is, 1² + 2² + 3² + ... + (2k)²= k(2k+1)(4k+1)/3.

We have to prove that this formula is true for the case n+1, i.e.1² + 2² + 3² + ... + (2n)² + [(2(n+1))]² = (n+1)[2(n+1)+1][4(n+1)+1]/3

Proof:

Now, we will prove the induction step, as follows:

(1² + 2² + 3² + ... + (2n)²)+ [(2(n+1))]²=(n+1)(2(n+1)+1)(4(n+1)+1)/3(k= n+1)

[Using Induction Hypothesis]= k(2k+1)(4k+1)/3= (n+1)[2(n+1)+1][4(n+1)+1]/3

Therefore, the formula is true for all positive integers n.

If x is a continuous random variable then P(x≥A) =  P(X>A). So, the correct option is C, i.e., P(X>A).

For a continuous random variable, the probability of X taking any specific value is zero, since there are infinitely many possible values that X could take. Instead, we calculate the probability that X falls within a certain range of values.

To find the probability that X is greater than or equal to A, we can use the cumulative distribution function (CDF) of X, denoted as F(X). The CDF F(X) gives the probability that X is less than or equal to a certain value x, i.e., F(X) = P(X ≤ x).

Now, since the event X ≥ A is the complement of the event X < A, we can use the complement rule to write:

P(X ≥ A) = 1 - P(X < A)

Using the definition of CDF, we get:

P(X ≥ A) = 1 - F(A)

Therefore, the probability of a continuous random variable X being greater than or equal to a certain value A is P(X>A) = 1 - F(A). This is the correct option C in the given question.

In order to rewrite these values in the standard form, let's calculate the product with the power of 10 from each number.

For the length, we have:

For the thickness, we have:

To count the number of relations R on set A such that at least one ordered pair in R has element a as its first element, we can consider the total number of relations on A and subtract the number of relations that do not have a as the first element in any ordered pair.

Given:

- Set A has 6 elements.

- Element a is one of the elements in A.

- Element b is also an element in A, and it is distinct from element a.

The total number of relations on set A is given by 2^(n^2), where n is the number of elements in A. In this case, n = 6.

Total number of relations on A = 2^(6^2) = 2^36

Now, let's calculate the number of relations on A that do not have a as the first element in any ordered pair. For any ordered pair in a relation, the first element can be any of the remaining 5 elements in A (excluding a). Similarly, the second element can be any of the 6 elements in A.

Number of relations without a as the first element = 5 * 6^2 = 180

Therefore, the number of relations R on A such that at least one ordered pair in R has a as its first element is:

Number of relations with a as the first element = Total number of relations on A - Number of relations without a as the first element

Number of relations with a as the first element = 2^36 - 180

Please note that the resulting number is an extremely large number.

Answer:

width is 47 and the length is 90

Step-by-step explanation:

Hello!

You find the perimeter by adding all the sides

l + l + w + w = p

The perimeter is 274

l + l + w + w = 274

It says the length is 4 less than double the width

l = 2w - 4

We can put this into the original equation

2w - 4 + 2w - 4 + w + w = 274

Now we solve

Combine like terms

6w - 8 = 274

Add 8 to both sides

6w = 282

Divide both sides by 6

w = 47

We can put w into the orginal equation to find l

l + l + 47 + 47 = 274

Combine like terms

2l + 94 = 274

Subtract 94 from both sides

2l = 180

Divide both sides by 2

l = 90

The answer is the width is 47 and the length is 90

Hope this helps!

Answer:

lenght: 90 yards

width: 47 yards

Step-by-step explanation:

perimeter = 2(length + width)

274 = 2(h + w)

h = 2w - 4

h = length

w = width

then:

274 = 2((2w-4) + w)

274/2 = 2w - 4 + w

137 = 3w - 4

137 + 4 = 3w

141 = 3w

w= 141/3

w = 47 yd

h = 2w - 4

h = 2*47  - 4

h = 94 - 4

h = 90 yd

probe:

274 = 2(47 + 90)

274 = 2(137)

x = \(\frac{5}{8}\)

Step-by-step explanation:

Given

- 4(3 + x) + 5 = 4(x + 3) ← distribute parenthesis on both sides

- 12 - 4x + 5 = 4x + 12 , that is

Answer:

x=3, y=-1

Step-by-step explanation:

We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation

2x-6y=12

We substitute 4y+7 in place of x

2(4y+7)-6y=12

Now we only have one variable to work on, distribute the 2

8y+14-6y=12

Combine similar terms, 8y-6y=2y

2y+14=12

Subtract 14 from both sides

2y=-2

y=-1

Now we plug in -1 for y in the first equation to find x

x=4(-1)+7

x=-4+7

x=3

The required solution of the given system of equations are x = 3 and y = -1.

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

The given system of equations is below as:

x = 4y + 7      ....(i)

2x - 6y = 12   ....(ii)

To solve the equations, use the substitution method.

Substitute the value of equation x = 4y+7 in (ii), and solve for y

2(4y + 7) - 6y = 12

8y + 14 - 6y = 12

8y - 6y = 2y

2y + 14 = 12

Subtract 14 from both sides of the equation

2y = -2

y = -1

Substitute the value of y = -1 in (i), and solve for x

x = 4(-1) + 7

x = -4 + 7

x = 3

Thus, the required solution of the given system of equations are x = 3 and y = -1.

For the budget constraint X + Y = 12, there is no optimal bundle that maximizes the utility function U(X, Y).

A) To find the optimal bundle, we need to maximize the utility function U(X, Y) subject to the budget constraint 3X + 5Y = 60.

Let's solve this problem using the Lagrange multiplier method:

1. Set up the Lagrangian function:

L(X, Y, λ) = -(X - 7)^2 - (Y - 7)^2 + λ(3X + 5Y - 60)

2. Find the first-order conditions:

∂L/∂X = -2(X - 7) + 3λ = 0

∂L/∂Y = -2(Y - 7) + 5λ = 0

∂L/∂λ = 3X + 5Y - 60 = 0

3. Solve the system of equations:

-2X + 14 + 3λ = 0    --(1)

-2Y + 14 + 5λ = 0    --(2)

3X + 5Y - 60 = 0     --(3)

From equations (1) and (2), we can solve for X and Y:

X = (14 - 3λ) / 2

Y = (14 - 5λ) / 2

Substituting these expressions into equation (3), we can solve for λ:

3(14 - 3λ) / 2 + 5(14 - 5λ) / 2 - 60 = 0

Simplifying and solving the equation, we find λ = -4.

Substituting λ = -4 back into X and Y expressions:

X = (14 - 3(-4)) / 2 = 13

Y = (14 - 5(-4)) / 2 = 9

Therefore, the optimal bundle is X = 13 and Y = 9.

B) To find the optimal bundle for the budget constraint X + Y = 12, we can rewrite it as Y = 12 - X.

Substituting this into the utility function, we have U(X) = -(X - 7)^2 - (12 - X - 7)^2.

To find the optimal bundle, we need to find the maximum value of U(X) by taking the derivative with respect to X and setting it equal to zero:

dU/dX = -2(X - 7) + 2(12 - X - 7) = 0

Simplifying the equation, we find:

-2X + 14 + 2X - 40 = 0

-26 = 0

Since -26 ≠ 0, there is no value of X that satisfies the first-order condition for optimization.

The series 16+24+36+54+... diverges.

Divergent series are those that contain an infinite series that never converges and an infinite sequence of partial sums with no finite limit. In contrast, a series is considered to be convergent when its limits converge to its finite range of values. A limit that is finite in nature and exists for the partial sum of the series is crucial since only at that point will the series converge.

The given series in question 16 + 24 + 36 + 54 + deviates from the series. 16n, where n is the number of terms, can be used to denote the series' overall term. The total of the terms in the series also increases as n increases since 16n grows along with n, too. This indicates that the series diverges since it does not reach a particular finite value.

To find the equations of the secant line and the tangent line for the given function f(x) = 2 + x, when x takes certain values, we need to use the slope-intercept form of a line, which is y = mx + b, where m represents the slope and b represents the y-intercept.

(a) Secant Line:

Let's find the equation of the secant line through the points where x takes the values x₁ = 4 and x₂ = 1.

The slope of the secant line is given by:

m = (f(x₂) - f(x₁)) / (x₂ - x₁)

Substituting the function f(x) = 2 + x into the slope formula, we have:

m = (f(1) - f(4)) / (1 - 4)

= ((2 + 1) - (2 + 4)) / (1 - 4)

= (3 - 6) / (-3)

= -3 / -3

= 1

Since the slope of the secant line is 1, we can choose any of the given points to find the equation. Let's use the point (4, f(4)) = (4, 2 + 4) = (4, 6):

Using the point-slope form of a line, we can write the equation of the secant line as:

y - y₁ = m(x - x₁)

y - 6 = 1(x - 4)

y - 6 = x - 4

y = x + 2

Therefore, the equation of the secant line is y = x + 2.

(b) Tangent Line:

To find the equation of the tangent line when x has the value x₁ = 4, we need to find the derivative of the function f(x) = 2 + x.

The derivative of f(x) with respect to x gives us the slope of the tangent line:

f'(x) = d/dx (2 + x)

= 1

The slope of the tangent line is equal to the derivative of the function evaluated at x = 4, which is 1.

Using the point-slope form of a line and the given point (4, f(4)) = (4, 2 + 4) = (4, 6), we can write the equation of the tangent line as:

y - y₁ = m(x - x₁)

y - 6 = 1(x - 4)

y - 6 = x - 4

y = x + 2

Therefore, the equation of the tangent line is y = x + 2, which is the same as the equation of the secant line in this case.
