Find the following matrix product, if possible. 6 -6 3 2 7 (: -1}{:}::) TO + 1 1 5 - 1 3

There are infinite numbers that are equivalent to 6.3.

Real numbers are those numbers that are either rational or irrational. Therefore, real numbers include both ration and irrational numbers.

The given number 6.3 can be rewritten in the form of a fraction as,

6.3 / 1

Multiply both the numerator and the denominator by a,

= 6.3a / a

In the above-formed fraction, the value of a can be any real number, because at the end a in the numerator will be cancelled by the a in the denominator. For instance let's take the value of a as 2, 10 and 1000.

When a=2,

(6.3×2) / (1 × 2) = 12.6/2

When a=10,

(6.3×10) / (1 × 10) = 63 / 10

When a=1000,

(6.3×1000) / (1 × 1000) = 6300 / 1000

Further, as a can be any real number, therefore, there are infinite numbers that are equivalent to 6.3.

The derivative for f(x) = 1032 . 1057  is 0

To find the derivative of the function f(x) = 1032 * 1057, we can use the power rule of differentiation, which states that the derivative of a constant raised to a power is equal to the product of the constant, the power, and the derivative of the expression inside the parentheses.

Using this rule, we have:

f(x) = 1032 * 1057

f'(x) = d/dx (1032 * 1057)

f'(x) = 1032 * d/dx (1057) + 1057 * d/dx (1032)

Since 1032 and 1057 are constants, their derivatives with respect to x are 0, so we can simplify the expression to:

f'(x) = 0 + 0 = 0

Therefore, the derivative of f(x) = 1032 * 1057 with respect to x is 0.

The nth partial sum of the series  1 È (on "(035) sin sin n.5 n+6 1 50 is option the sum of the series is 1238.78.

To find the formula for the nth partial sum of the series, we can use the formula for the sum of a finite geometric series:

S_n = a(1 - r^n) / (1 - r)

where a is the first term, r is the common ratio, and n is the number of terms.

In this series, the first term is 1/(n^0.35 sin(n+6))^2 and the common ratio is (0.35/(n+1))^2. So we have:

S_n = (1/(n^0.35 sin(n+6))^2) * (1 - (0.35/(n+1))^2^n) / (1 - 0.35/(n+1))^2

To determine if the series converges or diverges, we need to take the limit as n approaches infinity of the nth partial sum:

lim(n→∞) S_n

If the limit exists and is finite, the series converges. Otherwise, it diverges.

Taking the limit, we have:

lim(n→∞) S_n = lim(n→∞) (1/(n^0.35 sin(n+6))^2) * (1 - (0.35/(n+1))^2^n) / (1 - 0.35/(n+1))^2

Since the denominator goes to 1 as n approaches infinity, we can simplify to:

lim(n→∞) S_n = lim(n→∞) (1/(n^0.35 sin(n+6))^2) * (1 - (0.35/(n+1))^2^n)

Now, we need to consider the behavior of each term as n approaches infinity. First, note that sin(n+6) is bounded between -1 and 1, so (sin(n+6))^2 is bounded between 0 and 1.

Next, consider the term (0.35/(n+1))^2^n. As n approaches infinity, this term goes to 0, since the exponent grows much faster than the base.

Therefore, the limit of the nth partial sum is 0, which means the series converges.

To find the sum of the series, we can take the limit of the entire series as n approaches infinity:

sum(n=1 to infinity) 1/(n^0.35 sin(n+6))^2

Since we know the series converges, we can use the formula for the sum of an infinite geometric series:

sum = a / (1 - r)

where a is the first term and r is the common ratio.

In this series, the first term is 1/(1^0.35 sin(1+6))^2 = 1/0.035^2 and the common ratio is (0.35/2)^2 = 0.06125.

So we have:

sum = (1/0.035^2) / (1 - 0.06125) = 1238.78

Therefore, the sum of the series is 1238.78.

The volume of the composite solid made up of a cube with a side length of 6 meters and a hemisphere with a diameter of 6 meters can be found by adding the volume of the cube and the volume of the hemisphere, which yields 216 + 56.55approx 2762.55 cubic meters rounded to the nearest hundredth.

First, let's find the volume of the cube. The formula for the volume of a cube is V = s^3, where V is the volume and s is the side length. In this case, the side length is 6 meters. So, the volume of the cube is:

V_cube = 6^3 = 216 cubic meters

Next, we'll find the volume of the hemisphere. The formula for the volume of a sphere is V = (4/3)πr^3, where V is the volume and r is the radius. Since we're dealing with a hemisphere, we'll need to take half of the sphere's volume. The diameter of the hemisphere is 6 meters, which means the radius is 3 meters. The volume of the hemisphere is:

V_hemisphere = 0.5 * (4/3)π(3)^3 = 0.5 * (4/3)π(27) ≈ 56.55 cubic meters

Now, we'll add the volume of the cube and the volume of the hemisphere to find the total volume of the composite solid:

V_total = V_cube + V_hemisphere ≈ 216 + 56.55 ≈ 272.55 cubic meters

Rounded to the nearest hundredth, the volume of the composite solid is approximately 272.55 cubic meters.

The rate of change of the distance from the particle to the origin at this instant is 12.247 units/second.

Let's call the distance from the particle to the origin at a certain point (x, y) as d(x, y). Then, by the Pythagorean theorem, we have:

d(x, y) = √(x^2 + y^2)

We want to find the rate of change of d(x, y) with respect to time t, which we can write as:

d/dt [d(x, y)]

To find this, we need to express d(x, y) in terms of t. We know that the particle is moving along the curve y = 2√5x + 11, so we can substitute this into the equation for d(x, y):

d(x, y) = √(x^2 + y^2) = √(x^2 + (2√5x + 11)^2)

Now we can use the chain rule to find d/dt [d(x, y)]:

d/dt [d(x, y)] = d/dt [√(x^2 + (2√5x + 11)^2)]

= (1/2) (x^2 + (2√5x + 11)^2)^(-1/2) * d/dt [x^2 + (2√5x + 11)^2]

We already know that dx/dt = 5, so we just need to find dy/dt:

dy/dx = d/dx [2√5x + 11] = √5

dy/dt = dy/dx * dx/dt = √5 * 5 = 5√5

Now we can substitute dx/dt and dy/dt into the expression we found for d/dt [d(x, y)]:

d/dt [d(x, y)] = (1/2) (x^2 + (2√5x + 11)^2)^(-1/2) * (2x + 4(2√5x + 11) dx/dt)

= (1/2d(x, y)) (x + 4(√5x + 11)) dx/dt

Finally, we can substitute the values for x and dx/dt that we know from the problem:

x = 5

dx/dt = 5

And we can substitute the expression we found for d(x, y) back into the equation for d/dt [d(x, y)]:

d/dt [d(x, y)] = (1/2√(x^2 + (2√5x + 11)^2)) (x + 4(√5x + 11)) dx/dt

= (1/2√(5^2 + (2√5(5) + 11)^2)) (5 + 4(√5(5) + 11)) (5)

Simplifying this expression gives:

d/dt [d(x, y)] ≈ 12.247 units/second

So the rate of change of the distance from the particle to the origin at the instant when the particle passes through the point (5, 12) is approximately 12.247 units/second.

To find the average value of f(x, y) on the given rectangle, we need to calculate the double integral of f(x, y) over the rectangle and then divide the result by the area of the rectangle. Average value = 1125

First, we integrate f(x, y) with respect to y from 0 to 3:

∫[0,3] (x^2 + 10y) dy = [x^2y + 5y^2] from 0 to 3
= 9x^2 + 45

Next, we integrate this result with respect to x from 0 to 15:

∫[0,15] (9x^2 + 45) dx = [3x^3 + 45x] from 0 to 15
= 6765

Finally, we divide this result by the area of the rectangle, which is 15 x 3 = 45:

Average value of f(x, y) = 6765 / 45
= 150.33 (rounded to two decimal places)

Therefore, the average value of f(x, y) = x^2 + 10y on the rectangle 0 ≤ x ≤ 15, 0 ≤ y ≤ 3 is 150.33.

To find the average value of f(x, y) = x^2 + 10y on the rectangle 0 ≤ x ≤ 15, 0 ≤ y ≤ 3, you need to calculate the double integral of the function over the given region and divide it by the area of the rectangle.

First, find the area of the rectangle: A = (15-0)(3-0) = 45

Next, set up the double integral: ∬(x^2 + 10y) dy dx, with x ranging from 0 to 15 and y ranging from 0 to 3.

Now, evaluate the double integral:
∫(∫(x^2 + 10y) dy) dx = ∫(x^2*y + 5y^2) | y=0 to 3 dx = ∫(3x^2 + 45) dx
∫(3x^2 + 45) dx = (x^3 + 45x) | x=0 to 15 = 15^3 + 45*15 = 50625

Finally, divide the result by the area of the rectangle to find the average value:
Average value = (50625)/45 = 1125

The equation (1), which is equivalent to p'(x) = -3p(x), has exactly three distinct real solutions.

Let p(x) = (x - a)(x - b)(x - c)(x - d). Then p(x) = 0 has exactly four distinct real solutions, namely a, b, c, and d.

Taking the logarithmic derivative of p(x), we get:

p'(x)/p(x) = 1/(x - a) + 1/(x - b) + 1/(x - c) + 1/(x - d)

Multiplying both sides by p(x), we obtain:

p'(x) = p(x) / (x - a) + p(x) / (x - b) + p(x) / (x - c) + p(x) / (x - d)

Simplifying, we get:

p'(x) = (x - b)(x - c)(x - d) + (x - a)(x - c)(x - d) + (x - a)(x - b)(x - d) + (x - a)(x - b)(x - c)

Therefore, the equation (1) can be written as p'(x) = -3p(x).

By Rolle's theorem, between any two distinct real roots of p(x) (i.e., a, b, c, and d), there must be at least one real root of p'(x). Since p(x) has four distinct real roots, p'(x) must have at least three distinct real roots.

Moreover, since p(x) has degree 4, it can have at most four distinct real roots. Therefore, p'(x) = 0 can have at most four distinct real roots. Since we know that p'(x) has at least three distinct real roots, it follows that p'(x) = 0 has exactly three distinct real roots.

b)  F(1000) = F(999) + F(998)

c)  F(1000) = F(998) + F(997) + F(996)

Using the formula for the Fibonacci sequence: F(n) = F(n-1) + F(n-2), with F(0) = 0 and F(1) = 1, we can find F(12) by repeatedly applying the formula:

F(2) = F(1) + F(0) = 1 + 0 = 1

F(3) = F(2) + F(1) = 1 + 1 = 2

F(4) = F(3) + F(2) = 2 + 1 = 3

F(5) = F(4) + F(3) = 3 + 2 = 5

F(6) = F(5) + F(4) = 5 + 3 = 8

F(7) = F(6) + F(5) = 8 + 5 = 13

F(8) = F(7) + F(6) = 13 + 8 = 21

F(9) = F(8) + F(7) = 21 + 13 = 34

F(10) = F(9) + F(8) = 34 + 21 = 55

F(11) = F(10) + F(9) = 55 + 34 = 89

F(12) = F(11) + F(10) = 89 + 55 = 144

Therefore, F(12) = 144.

(b) F(1000) = F(999) + F(998)

We know that F(1000) = F(999) + F(998) from the formula F(n) = F(n-1) + F(n-2). Therefore, F(1000) can be expressed as the sum of F(999) and F(998).

(c) F(1000) = F(998) + F(997) + F(996)

Using the same formula, we can write F(1000) as F(999) + F(998), and then substitute F(999) with the sum of F(998) and F(997) to get:

F(1000) = F(999) + F(998) = F(998) + F(997) + F(998) = F(998) + F(997) + F(996)

The number of loops in the curve is determined by the positive integer n, with even values resulting in half as many loops, and odd values corresponding to an equal number of loops.

The number of loops in the family of curves given by the polar equations is related to the value of the positive integer, . Specifically, if  is even, then the number of loops in the curve is  when  is a multiple of 2, and  when  is an odd multiple of 2.

On the other hand, if  is odd, then the number of loops in the curve is  when  is a multiple of 2, and  when  is an odd multiple of 2. This relationship can be explained by considering the symmetry of the curves in relation to the polar axis. When  is even, the curves exhibit -fold symmetry, which leads to  loops for even multiples of 2 and  loops for odd multiples of 2. When  is odd, the curves exhibit -fold symmetry, which leads to  loops for even multiples of 2 and  loops for odd multiples of 2.

The family of curves given by polar equations with positive integer n is related to the number of loops through their symmetry and periodicity. The number of loops in the curve is directly proportional to the value of n. Specifically, if n is even, the curve has n/2 symmetrical loops, and if n is odd, it has n loops. This relationship can be observed by examining the graph of the polar equations and analyzing the behavior of the curve as n varies.

By Integrating the function f(x, y) is: f(x, y) = x^2y + x^2y + 24y^4 = 2x^2y + 24y^4

The gradient of a function represents its vector of partial derivatives with respect to each variable. In this case, if we assume f(x, y) = 2x^2y + 24y^4, the partial derivatives of f with respect to x and y are:

∂f/∂x = 4xy

∂f/∂y = 2x^2 + 96y^3

To find the original function f(x, y) from its gradient, we need to integrate each partial derivative with respect to its corresponding variable.

Integrating ∂f/∂x = 4xy with respect to x, we get:

∫(4xy) dx = 2x^2y + C(y),

where C(y) is the constant of integration with respect to x. Notice that the integration involves treating y as a constant because we are integrating with respect to x.

Next, integrating ∂f/∂y = 2x^2 + 96y^3 with respect to y, we get:

∫(2x^2 + 96y^3) dy = 2x^2y + 24y^4 + C(x),

where C(x) is the constant of integration with respect to y. Here, we treat x as a constant during the integration.

Combining these results, we have:

f(x, y) = 2x^2y + 24y^4 + C(x) = 2x^2y + 2x^2y + 24y^4 + C(x).

Simplifying, we find:

f(x, y) = 4x^2y + 24y^4 + C(x).

To find f, we integrate each component of the gradient with respect to its corresponding variable.

Integrating 2xy with respect to x gives us x^2y, and integrating (x^2 + 72y^3) with respect to y gives us x^2y + 24y^4.

Therefore, the function f(x, y) is:

f(x, y) = x^2y + x^2y + 24y^4 = 2x^2y + 24y^4

The partitioning of the array A = [3, 6, 2, 8, 7, 9, 5, 1, 4] with Partition(A, 1, 9) manually results in [3, 2, 1, 4, 7, 9, 5, 8, 6].

We are given an array A containing 9 elements. We need to perform the following tasks:

5a. Compute the Partition function on A, where the function takes in the array A and two indices (1 and 9 in this case) as arguments. Partition function is a part of the Quick Sort algorithm that partitions the array into two parts based on a pivot element.

5b. We need to consider two cases where the last element of the array A, A[9], is 14 and 0 respectively, and see how it affects our computation in 5a.

5c. Finally, we need to sort array A using the Bucket Sort algorithm with min-max scaling. The bucket Sort algorithm works by dividing the range of values into a series of buckets and then distributing the elements into those buckets. Min-max scaling is a technique used to scale the values of an array between 0 and 1.

The moose fat stores data has 10 degrees of freedom for the t-test.

To calculate the degrees of freedom for the t-test, we need to know the number of samples (n) for each group. From the given data, we can see that there are 6 moose fat stores data for when wolves are absent and 6 moose fat stores data for when wolves are present.

Therefore, the total number of samples is:

n = 6 + 6 = 12

And the degrees of freedom is:

degrees of freedom = n - 2 = 12 - 2 = 10

So the moose fat stores data has 10 degrees of freedom for the t-test.

To calculate the sample average and sample standard deviation, we can use the following formulas: Sample average (x bar) = (sum of all values) / (number of values)

Sample standard deviation (s) = sqrt((sum of (each value - sample average)^2) / (number of values - 1))

Using these formulas, we get:

x bar = (2.13 + 2.96 + 3.02 + 1.82 + 1.15 + 1.37 + 2.04 + 2.47 + 2.60) / 9

= 2.09 mm

To calculate the sample standard deviation, we first need to find the sum of (each value - sample average)^2:

(2.13 - 2.09)^2 + (2.96 - 2.09)^2 + (3.02 - 2.09)^2 + (1.82 - 2.09)^2 + (1.15 - 2.09)^2 + (1.37 - 2.09)^2 + (2.04 - 2.09)^2 + (2.47 - 2.09)^2 + (2.60 - 2.09)^2

= 0.0193 + 0.6809 + 0.7276 + 0.0256 + 0.7696 + 0.3364 + 0.0036 + 0.1624 + 0.2131

= 2.9385

Using this value and the number of values (9), we can calculate the sample standard deviation:

s = sqrt(2.9385 / (9 - 1))

= sqrt(0.3673)

= 0.6061 mm

To find the instantaneous velocity at t = 3, we need to take the derivative of the position function with respect to time:

s'(t) = 10t + 3

Then, we can plug in t = 3 to find the instantaneous velocity:

s'(3) = 10(3) + 3 = 33

Therefore, the instantaneous velocity at t = 3 is 33.

So, to find the instantaneous velocity of the object at t = 3, we first need to find the derivative of the position function s(t) = 5t² + 3t + 2 with respect to time (t). This derivative represents the velocity function, v(t).

Step 1: Differentiate s(t) with respect to t
v(t) = ds/dt = d(5t² + 3t + 2)/dt = 10t + 3

Step 2: Evaluate v(t) at t = 3
v(3) = 10(3) + 3 = 30 + 3 = 33

So, the instantaneous velocity of the object moving in a straight line at t = 3 is 33 units per time unit.

The probability that the store was not busy given you did not work late is approximately 0.8083 or 80.83%.

To find the probability that the store was not busy given you did not work late, we can use Bayes' theorem.

1. Let A be the event "store is not busy" and B be the event "did not work late".
2. We are given P(A') = 0.56, where A' is the event "store is busy". So, P(A) = 1 - P(A') = 1 - 0.56 = 0.44.
3. We are also given P(B'|A') = 0.84, where B' is the event "worked late". So, P(B|A') = 1 - P(B'|A') = 1 - 0.84 = 0.16.
4. Additionally, we are given P(B'|A) = 0.14. So, P(B|A) = 1 - P(B'|A) = 1 - 0.14 = 0.86.

Now we can apply Bayes' theorem to find P(A|B):

P(A|B) = (P(B|A) * P(A)) / (P(B|A) * P(A) + P(B|A') * P(A'))

P(A|B) = (0.86 * 0.44) / (0.86 * 0.44 + 0.16 * 0.56)
P(A|B) = (0.3784) / (0.3784 + 0.0896)
P(A|B) = 0.3784 / 0.468

P(A|B) = 0.8083

The total number of possible ways to create a license plate with 2 letters followed by 3 numbers if no repetition is 4,680,00.

To calculate the number of ways to create a license plate with 2 letters followed by 3 numbers, we need to consider two separate parts: the number of ways to choose the two letters, and the number of ways to choose the three numbers. Since no repetition is allowed, we have to take this into account in both parts.

For the first part, we have 26 choices for the first letter and 25 choices for the second letter, since we cannot choose the same letter twice.

For the second part, we have 10 choices for each of the three numbers. Again, we cannot choose the same number twice, so we have to decrease the number of choices by 1 for each subsequent number.

Thus, the total number of ways to create a license plate with 2 letters followed by 3 numbers is:

26 x 25 x 10 x 9 x 8 = 468,000

If no repetition of characters is allowed, then the number of possible ways to create a license plate with 2 letters followed by 3 numbers can be calculated as follows:

There are 26 choices for the first letter (A-Z).

There are 25 choices for the second letter (since no repetition is allowed).

There are 10 choices for the first number (0-9).

There are 9 choices for the second number (since no repetition is allowed).

There are 8 choices for the third number (since no repetition is allowed).

Therefore, the total number of possible ways to create a license plate with 2 letters followed by 3 numbers if no repetition is allowed is:

26 x 25 x 10 x 9 x 8 = 4,680,00

The preschool should choose Box A while shopping for sand for its sandbox. To determine which sandbox has more sand, we need to calculate the volume of each box using the formula V = lwh (volume = length × width × height).

For Box A:
- Width (w) = 9 inches
- Length (l) = 13 inches
- Height (h) = 15 inches

Applying the formula V = lwh, we get:

V_A = 9 × 13 × 15 = 1755 cubic inches

For Box B:
- Width (w) = 6 inches
- Length (l) = 12 inches
- Height (h) = 20 inches

Applying the formula V = lwh, we get:

V_B = 6 × 12 × 20 = 1440 cubic inches

Comparing the volumes, Box A (1755 cubic inches) has more sand than Box B (1440 cubic inches). So, the preschool should choose Box A while shopping for sand for its sandbox.

Less than 0.03% of IQ scores are at least 84, given a bell-shaped distribution with a mean of 10 and a standard deviation of 16.

The empirical rule is a statistical rule stating that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% of the data falls within two standard deviations of the mean, and 99.7% of the data falls within three standard deviations of the mean.

In this case, we know that the mean of the IQ scores is 10 and the standard deviation is 16. To find the percentage of IQ scores that are at least 84, we need to calculate how many standard deviations away from the mean 84 is.

To do this, we can use the formula:

z = (x - μ) / σ

Where:
z = number of standard deviations away from the mean
x = IQ score we are interested in (in this case, 84)
μ = mean of the distribution (10)
σ = standard deviation of the distribution (16)

Plugging in the numbers, we get:

z = (84 - 10) / 16
z = 4.00

This means that 84 is four standard deviations away from the mean. According to the empirical rule, only 0.03% of the data falls beyond three standard deviations from the mean. Therefore, we can estimate that the percentage of IQ scores that are at least 84 is less than 0.03%.

In conclusion, using the empirical rule, we can estimate that less than 0.03% of IQ scores are at least 84, given a bell-shaped distribution with a mean of 10 and a standard deviation of 16.

The two values of [tex]\theta[/tex] in [tex][0.2\pi)[/tex] such that cos([tex]\theta[/tex]) = 5/17 are approximately 0.915 radians and 0.533 radians.

To find two values of [tex]\theta[/tex] in [tex][0.2\pi)[/tex] such that [tex]cos(\theta)[/tex] = 5/17, we can use inverse trigonometric functions. Specifically, we will use the arccosine function ([tex]cos^{-1[/tex]) to solve for [tex]\theta[/tex].

First, we need to recognize that cos([tex]\theta[/tex]) = adjacent/hypotenuse. Therefore, if [tex]cos(\theta)[/tex] = 5/17, we can draw a right triangle with the adjacent side equal to 5 and the hypotenuse equal to 17.

Using the Pythagorean theorem, we can solve for the opposite side of the triangle. It turns out that the opposite side is equal to [tex]\sqrt(17^2 - 5^2)[/tex] = 16.

Now we have all three sides of the triangle and we can use trigonometry to find the two possible values of [tex]\theta[/tex]. Using the arccosine function, we can solve for the angle [tex]\theta[/tex]:

[tex]\theta[/tex] = [tex]cos^{-1}(5/17)[/tex] = 1.184 radians (rounded to three decimal places)

However, since we are looking for two values of [tex]\theta[/tex] in [tex][0.2\pi)[/tex], we need to add [tex]2\pi[/tex] to this result until we get a value within the specified range:
[tex][0.2\pi)[/tex]
This value is not within the specified range of [tex][0.2\pi)[/tex], so we subtract [tex]2\pi[/tex] until we get a value within the range:

[tex]\theta[/tex] = 7.036 - [tex]2\pi[/tex] = 0.915 radians (rounded to three decimal places)

Therefore, the first value of [tex]\theta[/tex]  such that cos([tex]\theta[/tex] ) = 5/17 in [tex][0.2\pi)[/tex] is approximately 0.915 radians.

To find the second value of [tex]\theta[/tex], we need to use the symmetry of the cosine function. Since cos( [tex]\theta[/tex]) = cos(- [tex]\theta[/tex]), we can solve for the negative angle that has the same cosine value:

[tex]\theta[/tex] = -[tex]cos^{-1}(5/17)[/tex] = -1.184 radians (rounded to three decimal places)

Again, we need to add and subtract [tex]2\pi[/tex] until we get a value within the specified range:

[tex]\theta[/tex] = -1.184 + [tex]2\pi[/tex] = 5.159 radians (rounded to three decimal places)

[tex]\theta[/tex] = 5.159 - [tex]2\pi[/tex] = 0.533 radians (rounded to three decimal places)

Therefore, the second value of [tex]\theta[/tex] such that cos( [tex]\theta[/tex]) = 5/17 in [tex][0.2\pi)[/tex] is approximately 0.533 radians.

The function attains an absolute maximum at x ≈ 1.13 with a value of f(x) ≈ 2.35, and an absolute minimum at x = 2 with a value of f(x) ≈ -8.77 on the interval [1/2, 2].

To verify that the given function f(x) = -4x^2 + 12x - 4ln(x) attains an absolute maximum and minimum on the interval [1/2, 2], we need to find critical points and evaluate the function at the interval's endpoints.

First, find the first derivative of the function:
f'(x) = d/dx (-4x^2 + 12x - 4ln(x))
f'(x) = -8x + 12 - 4/x

Set the first derivative equal to zero and solve for x to find critical points:
-8x + 12 - 4/x = 0

To find the critical points, we can use the quadratic formula, but since the function is not quadratic, we can instead use numerical methods or graphing to find approximate values. We find that there is a critical point at x ≈ 1.13.

Next, evaluate the function at the critical point and the endpoints of the interval:
f(1/2) ≈ -2.55
f(1.13) ≈ 2.35
f(2) ≈ -8.77

From these evaluations, we see that the function attains an absolute maximum at x ≈ 1.13 with a value of f(x) ≈ 2.35, and an absolute minimum at x = 2 with a value of f(x) ≈ -8.77 on the interval [1/2, 2].
