To prove that a² is algebraic, we need to find a polynomial in F[x] that has a² as a root. Let's start by considering the polynomial with coefficients depending on a's:

p(x) = (x - a²)

If we substitute x = a into this polynomial, we get:

p(a) = (a - a²) = a(1 - a)

Since a is a root of ao + a1x +... + anx^n, we know that:

ao + a1a +... + ana^n = 0

Multiplying both sides by a, we get:

a ao + a1a² +... + ana^{n+1} = 0

Substituting a(1 - a) for a², we get:

a ao + a1(a(1 - a)) +... + an(a(1 - a))^n = 0

Simplifying, we get:

a ao + a1a(1 - a) +... + ana^n(1 - a)^n = 0

Multiplying both sides by (1 - a)^n, we get:

a ao(1 - a)^n + a1a(1 - a)^{n+1} +... + ana^n(1 - a)^{2n} = 0

Now, let's group the terms by even powers of a and odd powers of a:

a^0(1 - a)^n ao + a^2(1 - a)^{n+1} a1 +... + a^{2n}(1 - a)^{2n} an = 0

This is a polynomial in F[x] with a² as a root. Therefore, we have proved that a² is algebraic.

[tex]f(t) = - 16 {t}^{2} + 60t + 16[/tex]

A. x = (-60 + √(60^2 - 4(-16)(16))) / (2(-16))

= (-60 + √4,624)/-32

= (-60 + 68)/-32

= -1/4, 4

So the coordinates of the roots

(x-intercepts) are (-1/4, 0) and (4, 0).

B. The line of symmetry is

x = (-1/4 + 4)/2 = (15/4)(1/2) = 15/8 = 1.875

f(1.875) = -16(15/8)^2 + 60(15/8) + 16

So the vertex is (1.875, 72.25).

C. Plot the roots and the vertex on the graph. f(1) = 60, f(2) = 72, and f(3) = 52, so plot (1, 60), (2, 72), and (3, 52).

1a. To differentiate f(x) = 5x^4 - 4x + 7, we simply take the derivative of each term separately:
f'(x) = 20x^3 - 4

1b. For g(x) = 6√x + 9x^6, we first need to rewrite the square root as a power:
g(x) = 6x^(1/2) + 9x^6
Then, we take the derivative of each term:
g'(x) = 3x^(-1/2) + 54x^5

1c. It's unclear what function h(x) is supposed to be.

2. To find the equation of the line tangent to k(x) = 3x² - 7x + 4 at x = 2, we first need to find the slope of the tangent line, which is equal to the derivative of k(x) evaluated at x = 2:
k'(x) = 6x - 7
k'(2) = 5
So the slope of the tangent line at x = 2 is 5.

Next, we need to find the y-coordinate of the point on the curve that corresponds to x = 2:
k(2) = 3(2)^2 - 7(2) + 4 = 6 - 14 + 4 = -4

So the point on the curve that corresponds to x = 2 is (2, -4).

Finding an eigenvector of A may be difficult, but checking whether a given vector is in fact an eigenvector is easy. This statement is True.

Finding an eigenvector of a matrix A involves solving the equation $(A - \lambda I)\vec{v} = \vec{0}$, where $\lambda$ is an eigenvalue of A and $\vec{v}$ is the corresponding eigenvector.

This can be a challenging computational problem in general, especially for larger matrices or complex eigenvalues.

However, once a candidate eigenvector is found, it is easy to check whether it is in fact an eigenvector.

Simply multiply the vector by A and compare the result to the product of the eigenvalue and the original vector.

On the interval (-1, 1), the Fourier series for f(x) is f(x) = 1/2 + ∑[2/πn cos(nπx)] - [2/πn sin(nπx)].

To find the Fourier series for the given function f(x) on the interval (-1, 1), we need to determine its Fourier coefficients. The Fourier coefficient for the nth term can be calculated using the following formula:

an = (2/L) ∫f(x) cos(nπx/L) dx, where L is the period of the function, which in this case is 2.

bn = (2/L) ∫f(x) sin(nπx/L) dx, where L is the period of the function, which in this case is 2.

We can evaluate these integrals separately for the intervals (-1, 0) and (0, 1) and then add the results to obtain the final Fourier coefficients.

For the interval (-1, 0), we have:

an = (2/2) ∫[1 + x] cos(nπx/2) dx from x = -1 to x = 0

an = [(1 + x) sin(nπx/2)/πn] from x = -1 to x = 0

an = [0 - (-1) sin(nπ/2)/πn] - [(1 + 0) sin(0)/πn]

an = 2/πn

bn = (2/2) ∫[1 + x] sin(nπx/2) dx from x = -1 to x = 0

bn = [-(1 + x) cos(nπx/2)/(πn)] from x = -1 to x = 0

bn = [-1 cos(nπ/2)/(πn) - (1 + 0) cos(0)/(πn)]

bn = -2/πn

For the interval (0, 1), we have:

an = (2/2) ∫[1 - x] cos(nπx/2) dx from x = 0 to x = 1

an = [(1 - x) sin(nπx/2)/πn] from x = 0 to x = 1

an = [(1 - 0) sin(nπ/2)/πn] - [(1 - 1) sin(nπ)/πn]

an = 2/πn

bn = (2/2) ∫[1 - x] sin(nπx/2) dx from x = 0 to x = 1

bn = [- (1 - x) cos(nπx/2)/(πn)] from x = 0 to x = 1

bn = [-(1 - 1) cos(nπ)/πn] - [(1 - 0) cos(nπ/2)/(πn)]

bn = 0

Therefore, the Fourier series for f(x) on the interval (-1, 1) is:

f(x) = 1/2 + ∑[2/πn cos(nπx)] - [2/πn sin(nπx)], where the sum is taken from n = 1 to infinity.

The x-coordinate of the point that the line passes through is x = 0.

We can use the point-slope form of a linear equation to solve this problem.

The slope of the line can be found using the two given points:

slope  (change in y) / (change in x)

slope = (-3 - (-9)) / (12 - x)

slope = 6 / (x - 12)

Now we can use the point-slope form of the linear equation, with the y-intercept of 6:

y - 6 = slope * (x - 0)

Substituting the slope we just found:

y - 6 = (6 / (x - 12)) * x

Simplifying:

y - 6 = 6x / (x - 12)

Multiplying both sides by (x - 12):

y(x - 12) - 6(x - 12) = 6x

Distributing:

xy - 12y - 6x + 72 = 6x

Moving the x terms to one side:

xy - 12y - 12x + 72 = 0

Now we can substitute the y-coordinate of the other given point, (-9), and solve for x:

x(-9) - 12(6) - 12x + 72 = 0

Simplifying:

-9x - 72 - 12x + 72 = 0

A percentile is a measure used in statistics to indicate the value below which a given percentage of observations fall. For example, if a data set has a 75th percentile value of 100, then 75% of the observations in the data set fall below the value of 100.

To find the 11th percentile for the given normal distribution with mean μ=58 and standard deviation σ=8, we need to use a standard normal distribution table or a calculator.

We can start by converting the given value to a z-score using the formula:

z = (X - μ) / σ

Where X is the value we want to find the percentile for, μ is the mean, and σ is the standard deviation.

Plugging in the values given, we get:

z = (X - 58) / 8

To find the z-score for the 11th percentile, we can use a standard normal distribution table or calculator to find the z-score associated with a cumulative probability of 0.11.

Using a calculator or table, we find that the z-score associated with a cumulative probability of 0.11 is -1.23.

We can now solve for X using the z-score formula:

z = (X - μ) / σ

-1.23 = (X - 58) / 8

Solving for X, we get:

X = -1.23 * 8 + 58 = 48.16

Therefore, the 11th percentile for this normal distribution is 48.16. This means that 11% of the observations in this distribution fall below the value of 48.16.

A Z-score represents the number of standard deviations an observation is from the mean of the distribution. The formula for calculating a Z-score is:

Z = (X - μ) / σ

In this case, you need to find the Z-score corresponding to the 11th percentile. To do this, you can refer to the Z-table, which provides the area (probability) to the left of a given Z-score. Look for the value closest to 0.11 (representing 11%) in the table. You will find that the Z-score associated with the 11th percentile is approximately -1.23.

Now, you can use the Z-score formula to solve for X:

-1.23 = (X - 58) / 8

To solve for X, perform the following calculations:

X - 58 = -1.23 * 8
X - 58 = -9.84
X = 58 - 9.84
X ≈ 48.16

So, the 11th percentile of the normally distributed random variable X with a mean of 58 and standard deviation of 8 is approximately 48.16.

The number of ways to place 10 paintings into 8 boxes with at least one painting in each box is C(9,2) = 36.

The number of ways to place 5 paintings into 3 boxes when some boxes can be empty is C(7,2) = 21.

(a) To place 10 paintings into 8 boxes with at least one painting in each box, we can use the concept of distributing identical items into distinct groups. We will first place one painting in each box, leaving us with 2 paintings to distribute among the 8 boxes. We can use the "stars and bars" method to solve this problem. We have 2 "stars" (paintings) and need to separate them using 7 "bars" (box dividers). We can think of this as choosing 2 positions from 9 available positions (2 stars + 7 bars). Therefore, the number of ways to place 10 paintings into 8 boxes with at least one painting in each box is C(9,2) = 36.

(b) To place 5 paintings into 3 boxes without the restriction that each box must have a painting, we will again use the "stars and bars" method. In this case, we have 5 "stars" (paintings) and 2 "bars" (box dividers). We can think of this as choosing 2 positions from 7 available positions (5 stars + 2 bars). Therefore, the number of ways to place 5 paintings into 3 boxes when some boxes can be empty is C(7,2) = 21.
