We have to find the amount that Maya painted IN ALL, which means we must add 3/4 and 1/8. First, look for the answer choice that has 1/8 as a number (B and A). However, none of the answer choices have 3/4 as an answer, so we must convert it into an equivalent fraction, 6/8. You get 6/8 by multiplying both the numerator and denominator by 2. Therefore the answer is B.

2.5(cos 5π/6  + i sin 5π/6) is the polar form  of the complex number

Complex numbers are numbers that are expressed in the form of a+ib, where a and b are real numbers and 'i' is an imaginary number called “iota”. The value of i = (√-1)

Given: the complex number (5√3)/4 - 5/4 i

In polar form:

(5√3)/4 - 5/4 i = r(cosθ + isinθ)

θ  = tan⁻¹( (-5/4) / (5√3 /4) )

θ = -30°

θ = -30+180 = 150°

θ = 5π/6

r = √( (5√3)/4)² +(- 5/4)²) = 2.5

Thus,

(5√3)/4 - 5/4 i = r(cosθ + isinθ)

r(cosθ + isinθ) = 2.5(cos 5π/6  + i sin 5π/6 )

Therefore, the polar form  of the complex number is 2.5(cos 5π/6  + i sin 5π/6)

Answer:

If the video game that Ethan bought usually costs $39.99, and it was on sale for 20% off, then the discount on the game would be $39.99 x 20/100 = $8.00. To determine the final price of the game after the discount, we can subtract the discount from the original price of the game, which gives us:

Final price = $39.99 - $8.00 = $31.99

Therefore, Ethan paid $31.99 for the video game that was on sale. This can be rounded to the nearest cent to give us a final answer of:

Final price = $31.99 ≈ $32.00.

Therefore, Ethan paid $32.00 for the video game that was on sale.

Step-by-step explanation:

The factored form of the polynomial y² + 5y - 24 is:(y + 8)(y - 3)

To factor the polynomial y² + 5y - 24, we need to find two binomial factors that, when multiplied, give us the original polynomial.To factor this polynomial, we can look for two numbers whose sum is 5 and whose product is -24. After considering different combinations, we find that the numbers are 8 and -3.We can use the method of "splitting the middle term" to factorize the polynomial.

Multiply the coefficient of the leading term (y²) and the constant term (-24). The product is -24.

y² * -24 = -24y²

Find two numbers whose sum is equal to the coefficient of the middle term (5) and whose product is equal to the result from step 1 (-24). In this case, the numbers are 8 and -3.

8 + (-3) = 5

8 * (-3) = -24

Rewrite the middle term (5y) using the two numbers found in step 2.

y² + 8y - 3y - 24

Group the terms and factor them by grouping:

(y² + 8y) + (-3y - 24)

Factor out the greatest common factor from each group:

y(y + 8) - 3(y + 8)

Notice that both groups have a common factor of (y + 8). Factor out this common factor:

(y + 8)(y - 3)

Therefore, the factored form of the polynomial y² + 5y - 24 is:

(y + 8)(y - 3)

it may be permissible to proceed with a hypothesis test even if the assumption of random participant selection is violated, under the conditions of known and accounted for non-random selection or random assignment to treatment groups

Random participant selection is an important assumption in hypothesis testing, as it helps ensure the generalizability of the results to the target population. However, in some situations, it may be impractical or impossible to achieve perfect random selection. In such cases, there are a few conditions under which it may still be permissible to proceed with a hypothesis test despite the violation of this assumption:

Non-random selection is known and accounted for: If the non-random selection process is well-documented and understood, researchers can adjust their analysis or statistical methods to account for potential biases introduced by the non-random selection.

Random assignment to treatment groups: Even if participants are not randomly selected, random assignment to different treatment groups can help mitigate the impact of non-random selection. By randomly assigning participants to treatment groups, the effects of non-random selection are distributed evenly across the groups, allowing for valid comparisons and hypothesis testing.

The gravitational potential energy of the wire can be calculated as PE = mgh = mg(r - (r^2 - (l/2)^2)^0.5) * (2r/π).

To find the gravitational potential energy of the thin wire, we need to use the equation PE = mgh, where m is the mass of the wire, g is the acceleration due to gravity, and h is the height of the wire above a reference point.

Since the wire is in a semicircular shape, we can find the height h using the Pythagorean theorem. Let the radius of the semicircle be r, then the height h can be found as h = r - (r^2 - (l/2)^2)^0.5.

Once we have the height h, we can calculate the gravitational potential energy of the wire. However, we also need to take into account the fact that the wire is bent in a semicircular shape.

To do this, we need to calculate the average height of the wire above the x-axis, which is given by (2r/π).

Therefore, the gravitational potential energy of the wire can be calculated as PE = mgh = mg(r - (r^2 - (l/2)^2)^0.5) * (2r/π).

The solution to the system of differential equations is x(t) = -\(3e^{(31t)\) and z(t) = -\(3e^{(31t\)).

To solve the given system of differential equations, we'll begin by finding the eigenvalues and eigenvectors of the coefficient matrix.

The coefficient matrix is A = [[-22, 54], [-9, 23]]. To find the eigenvalues λ, we solve the characteristic equation det(A - λI) = 0, where I is the identity matrix.

det(A - λI) = [[-22 - λ, 54], [-9, 23 - λ]]

=> (-22 - λ)(23 - λ) - (54)(-9) = 0

=> λ^2 - λ(23 + 22) + (22)(23) - (54)(-9) = 0

=> λ^2 - 45λ + 162 = 0

Solving this quadratic equation, we find the eigenvalues:

λ = (-(-45) ± √((-45)^2 - 4(1)(162))) / (2(1))

λ = (45 ± √(2025 - 648)) / 2

λ = (45 ± √1377) / 2

The eigenvalues are λ₁ = (45 + √1377) / 2 and λ₂ = (45 - √1377) / 2.

Next, we'll find the corresponding eigenvectors. For each eigenvalue, we solve the equation (A - λI)v = 0, where v is the eigenvector.

For λ₁ = (45 + √1377) / 2:

(A - λ₁I)v₁ = 0

=> [[-22 - (45 + √1377) / 2, 54], [-9, 23 - (45 + √1377) / 2]]v₁ = 0

Solving this system of equations, we find the eigenvector v₁.

Similarly, for λ₂ = (45 - √1377) / 2, we solve (A - λ₂I)v₂ = 0 to find the eigenvector v₂.

The general solution of the system is x(t) = c₁e(λ₁t)v₁ + c₂e(λ₂t)v₂, where c₁ and c₂ are constants.

Using the initial condition x(0) = -3, we can substitute t = 0 into the general solution and solve for the constants c₁ and c₂.

Finally, substituting the values of c₁ and c₂ into the general solution, we obtain the particular solution for x(t).

Since z(t) = x(t), the solution for z(t) is the same as x(t).

Therefore, the solution to the system of differential equations is x(t) = \(-3e^{(31t)\) and z(t) = -\(3e^{(31t)\).

Step-by-step explanation:

The value of n is -5.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms provide the basis of expressions.

A variable is a letter, like x, y, or z, that stands in for an arbitrary number.

6+x=12

You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression. Since 6 + 6 equals 12, the variable x in the example above is equal to 6.

If we are aware of the values of our variables, we can substitute those values for the original variables before evaluating the expression.

You must increase \(x^{-8} * x^{3}\). According to the laws of exponents, you can simply add the exponents when multiplying exponents with the same base, which will raise the base to the sum of the exponents.

So, \(x^{-8} *x^{3} = x^{-8+3} =x^{-5}\)

n equals -5 because our final result is.

The characteristic polynomial of T splits,  the characteristic polynomial of the restriction of T to any T-invariant subspace of V also splits.

To prove the given statement, we need to show that if the characteristic polynomial of a linear operator T on a finite-dimensional vector space V splits, then the characteristic polynomial of the restriction of T to any T-invariant subspace of V also splits.

Let U be a T-invariant subspace of V. We want to show that the characteristic polynomial of T restricted to U splits.

First, let's consider the minimal polynomial of T, denoted by \(m_T_{(x).\)Since the characteristic polynomial of T splits, we know that it can be written as \(c(x-a_1)^{m_1}(x-a_2)^{m_2}...(x-a_k)^{m_k}\), where \(a_1, a_2, ..., a_k\) are distinct eigenvalues of T, and \(m_1, m_2, ..., m_k\) are their respective multiplicities.

Since U is T-invariant, it means that for any u ∈ U, T(u) ∈ U. Thus, the restriction of T to U, denoted by \(T|_U,\) is a well-defined linear operator on U.

Now, let's consider the minimal polynomial of T restricted to U, denoted by m_{T|U}(x). We want to show that m{T|_U}(x) splits.

For any eigenvalue λ of T|_U, there exists a nonzero vector u ∈ U such that T|_U(u) = λu. This implies that T(u) = λu, so u is also an eigenvector of T associated with the eigenvalue λ.

Since the characteristic polynomial of T splits, we have λ as one of the eigenvalues of T. Hence, the minimal polynomial m_T(x) must have a factor of (x-λ) in its factorization.

Since m_T(x) is also the minimal polynomial of T restricted to U, it follows that m_{T|_U}(x) must also have a factor of (x-λ) in its factorization.

Since this argument holds for any eigenvalue λ of T|_U, we conclude that the characteristic polynomial of T restricted to U,

given by det(xI - T|_U), can be factored as (x-λ_1\()^{n_1}\)(x-λ_2\()^{n_2}\)...(x-λ_p\()^{n_p},\)

where λ_1, λ_2, ..., λ_p are the distinct eigenvalues of T|_U, and n_1, n_2, ..., n_p are their respective multiplicities.

Therefore, we have shown that if the characteristic polynomial of T splits, then the characteristic polynomial of the restriction of T to any T-invariant subspace of V also splits.

16. The length of each side of the original garden is 12 meters. The answer is (C) 12m.

17The value of c that makes x^2-11x+c a perfect-square trinomial is (B) 121/4..

18.The answer is (D) -1. 1, -9. 1.

Step by step explanation

16. Let s be the length of each side of the original garden. Then the area of the original garden is s^2. If each side is increased by 3 meters, then the new length of each side is s+3, and the area of the expanded garden is (s+3)^2. We are given that the area of the expanded garden is 225 square meters. Therefore, we can write the equation:

(s+3)^2 = 225

Taking the square root of both sides, we get:

s+3 = 15 or s+3 = -15

The second equation has no solution, since the length of a side cannot be negative. Therefore, we have:

s+3 = 15

Subtracting 3 from both sides, we get:

s = 12

17. To make x^2-11x+c a perfect-square trinomial, we need to add and subtract a constant term to make it a square of a binomial. Specifically, we want to add and subtract (11/2)^2 = 121/4 to get:

x^2 - 11x + c + 121/4 - 121/4

= (x - 11/2)^2 + (4c - 121)/4

For this to be a perfect-square trinomial, we need (4c - 121)/4 to be equal to 0. Therefore, we have:

4c - 121 = 0

Solving for c, we get:

4c = 121

c = 121/4

18. To solve the equation x^2 + 8x = 10 by completing the square, we first move the constant term to the right-hand side:

x^2 + 8x - 10 = 0

Next, we add and subtract the square of half the coefficient of x, which is (8/2)^2 = 16:

x^2 + 8x + 16 - 16 - 10 = 0

We can then write the left-hand side as a perfect-square trinomial:

(x + 4)^2 - 26 = 0

Adding 26 to both sides, we get:

(x + 4)^2 = 26

Taking the square root of both sides, we get:

x + 4 = ±√26

Subtracting 4 from both sides, we get:

x = -4 ±√26
