The equation that is equivalent to 52 = -4 (2n + 1) is C) -52/4 = 2n + 1.

Starting with the given equation:

52 = -4 (2n + 1)

First, we can simplify the right-hand side of the equation by distributing the -4:

52 = -8n - 4

Then, we can isolate the variable (n) by adding 4 to both sides of the equation:

56 = -8n

Finally, we can solve for n by dividing both sides by -8:

-7 = n

Therefore, we have found that the solution to the equation 52 = -4 (2n + 1) is n = -7.

Now, let's check each of the answer choices to see if they are equivalent to this solution:

A) 13 = -2 (2n + 1)

If we simplify the right-hand side of this equation, we get:

13 = -4n - 2

Then, if we add 2 to both sides and divide by -4, we get:

-3.75 = n

This solution is not equivalent to n = -7, so this equation is not equivalent to the original equation.

B) -7 = -2 (2n + 1)

If we simplify the right-hand side of this equation, we get:

-7 = -4n - 2

Then, if we add 2 to both sides and divide by -4, we get:

1.25 = n

This solution is not equivalent to n = -7, so this equation is not equivalent to the original equation.

C) -52/4 = 2n + 1

If we simplify the left-hand side of this equation, we get:

-13 = 2n + 1

Then, if we subtract 1 from both sides and divide by 2, we get:

-7 = n

This solution is equivalent to n = -7, so this equation is equivalent to the original equation.

D) -13 = -4 (2n + 1)

If we simplify the right-hand side of this equation, we get:

-13 = -8n - 4

Then, if we add 4 to both sides and divide by -8, we get:

1.875 = n

This solution is not equivalent to n = -7, so this equation is not equivalent to the original equation.

Therefore, the equation that is equivalent to 52 = -4 (2n + 1) is C) -52/4 = 2n + 1.

The triangle solved  using the Law of Sines. D=10,∠A=30 4, and, C=120 4 where a = 5.77 c = 10 i = 30°

To solve the triangle, we need to use the formula:
a/sinA = b/sinB = c/sinC

Given that D=10, ∠A=30°, and C=120°, we can plug in these values into the formula and solve for the unknown sides:

a/sin30° = 10/sin120°

Cross-multiplying and solving for a gives us:

a = 10*sin30°/sin120°

a = 5.77

Similarly, we can solve for the other unknown side, c:

c/sinC = 10/sin120°

c = 10*sinC/sin120°

c = 10*sin120°/sin120°

c = 10

Finally, we can solve for the unknown angle, i, using the fact that the sum of the angles in a triangle is 180°:

i = 180° - 30° - 120°

i = 30°

Therefore, the solution to the triangle is:

a = 5.77
c = 10
i = 30°

Answer:

The formula for calculating the value of an investment that grows continuously is:

A = Pe^(rt)

Where:

A is the final amount

P is the principal amount

e is Euler's number (approximately 2.71828)

r is the annual interest rate (as a decimal)

t is the time in years

In this case, P = 5000, r = 0.025 (2.5% expressed as a decimal), and t = 7. Plugging these values into the formula, we get:

A = 5000 * e^(0.025*7) = 5000 * e^0.175 = 5000 * 1.19128 = 5956.40

Therefore, Ryan's investment will be worth $5,956.40 after 7 years. Rounded to the nearest cent, the answer is $5,956.40.

50 % of the total books are of Marathi = x*50/100 = x/2

Books of English are 1/3rd of Marathi = (x/2)*(1/3)

                                                              = x/6

Books on Mathematics are 25 % of the English books = (x/6)*(25/100)

                                                                                          = x/24

Remaining books = 560

Now, according to the question.

⇒ x/2 + x/6 + x/24 + 560/1 = x/1

⇒ (12x + 4x + x + 13440)/24 = x/1

⇒ 17x + 13440 = 24x

⇒ 24x - 17x = 13440

⇒ 7x = 13440

a) is linearly dependent and set b) is linearly independent.

By inspection, we can determine whether the given sets are linearly dependent by looking at the relationship between the vectors in each set. If one vector can be written as a linear combination of the other vectors in the set, then the set is linearly dependent.

For set a) \( \left\{\left[\begin{array}{l}1 \\ 3\end{array}\right],\left[\begin{array}{l}2 \\ 6\end{array}\right]\right\} \), we can see that the second vector is simply 2 times the first vector. This means that the second vector can be written as a linear combination of the first vector, and therefore the set is linearly dependent.

For set b) \( \left\{\left[\begin{array}{l}1 \\ 0 \\ 0\end{array}\right],\left[\begin{array}{l}0 \\ 1 \\ 0\end{array}\right],\left[\begin{array}{l}0 \\ 0 \\ 1\end{array}\right]\right\} \), we can see that none of the vectors can be written as a linear combination of the other vectors in the set. This means that the set is linearly independent.

Therefore, by inspection, we can determine that set a) is linearly dependent and set b) is linearly independent.

For the number of checks written greater than 42.5, a checking account at Long's Bank will generate more earnings income than one at Fellow's Bank.

Range of checks refers to a specific interval or set of values within which the number of checks written is included or applicable.

It is usually used in the context of analyzing financial data related to checking accounts, transactions, or other monetary activities.

To find the range of checks for which Long's Bank generates more earnings income than Fellow's Bank, we need to compare the two equations and solve for x.

I(Long's Bank) > I(Fellow's Bank)

-0.06x + 8.3 > -0.02x + 6.6 (Substitute the values of I for both banks)

0.04x > 1.7 (Simplify by combining like terms)

x > 42.5 (Divide both sides by 0.04 and reverse the inequality sign)

The x-coordinate of the midpoint of line segment AB is 29.5

What is coordinate?

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.

To find the x-coordinate of the midpoint of line segment AB, we can use the midpoint formula:

Midpoint x-coordinate = (x-coordinate of A + x-coordinate of B) / 2

We are given the coordinates of points A and B:

A(13, 5) and B(46, -13)

Using the midpoint formula, we can substitute the x-coordinates of A and B into the formula and simplify:

Midpoint x-coordinate = (13 + 46) / 2

= 29.5

Therefore, the x-coordinate of the midpoint of line segment AB is 29.5

(b)  The centralizer of S in G is the set {1, r^2}.

This means that the kernel of Φ is the set of all complex numbers with an imaginary part of 0, which is the set of all real numbers. That is, ker Φ = R.

The fundamental theorem of Group Hormomorphisms states that for any group homomorphism Φ: G -> H, the kernel of Φ, ker Φ, is a normal subgroup of G, and the image of Φ, im Φ, is a subgroup of H. Furthermore, G/ker Φ is isomorphic to im Φ.

(a) (i) To show that Φ is a homomorphism, we need to show that it preserves the group operation. That is, for any two elements x + iy and u + iv in C, we need to show that Φ((x + iy) + (u + iv)) = Φ(x + iy) + Φ(u + iv). Using the definition of Φ, we have:

Φ((x + iy) + (u + iv)) = Φ((x + u) + (y + v)i) = y + v

Φ(x + iy) + Φ(u + iv) = y + v

Since these two expressions are equal, Φ is a homomorphism.

(ii) The kernel of Φ, ker Φ, is the set of all elements in C that are mapped to the identity element in R, which is 0. That is, ker Φ = {x + iy : Φ(x + iy) = 0}. Using the definition of Φ, we have:

Φ(x + iy) = 0

y = 0

This means that the kernel of Φ is the set of all complex numbers with an imaginary part of 0, which is the set of all real numbers. That is, ker Φ = R.

(iii) To prove that C/ker Φ is isomorphic to R, we can use the fundamental theorem of Group Hormomorphisms. Since ker Φ = R, we have C/R ~= im Φ. Since the image of Φ is the set of all real numbers, we have C/R ~= R.

(b) The centralizer of a subset S of a group G, denoted by C_G(S), is the set of all elements in G that commute with every element in S. That is, C_G(S) = {g : g in G, gs = sg for all s in S}. For the given groups G = D6 and S = {1,r^2}, we have:

C_G(S) = {g : g in G, g1 = 1g and gr^2 = r^2g}

(a+b)³ = (a+b)(a+b)(a+b)

= (a+b)(a²+2ab+b²)

= a³ + 2a²b + ab² + a²b + 2ab² + b³

= a³ + 3a²b + 3ab² + b³

So the correct expansion of (a+b)³ has four terms, not two as Erin's shortcut suggests. Therefore, Erin's shortcut does not always work and should not be used.
