The composite function g(h(8)) when evaluated is 94.

From the question, we have the following parameters that can be used in our computation:

g(a) = 4a - 2

h(a) = 3a

To find g(h(8)), we need to first evaluate h(8), and then plug that result into g(a) and simplify.

h(a) is defined as 3a, so h(8) = 3(8) = 24.

Now we can plug in 24 for a in g(a) and simplify:

g(a) = 4a - 2

g(h(8)) = g(24) = 4(24) - 2 = 94

Therefore, g(h(8)) = 94.

To find the values of z that make the product with the complex number 5-6i a real number, we need to consider the imaginary part of the product.

The product of z and 5-6i can be written as:

z * (5 - 6i)

Expanding this expression, we get:

5z - 6zi

For the product to be a real number, the imaginary part (-6zi) must be equal to zero. This means that the coefficient of the imaginary unit i, which is -6z, must be zero.

Setting -6z = 0, we find:

z = 0

So, one possible nonzero value of z is 0.

However, since we are looking for nonzero values of z, we need to find another value that satisfies the condition.

Let's consider the equation for the imaginary part:

-6z = 0

Dividing both sides of the equation by -6, we have:

z = 0/(-6)

z = 0

Again, we find z = 0, which is not a nonzero value.

Therefore, there are no other nonzero values of z that make the product with the complex number 5-6i a real number. The only value that satisfies the condition is z = 0.

The inequalities that can be used with the squeeze theorem to find the limit of the function as x approaches 0 are:

0 ≤ |g(x)| ≤ |f(x)|

0 ≤ |h(x)| ≤ |f(x)|

To apply the squeeze theorem to find the limit of a function as x approaches 0, we need to find two functions that "squeeze" the given function and have the same limit as x approaches 0.

Let's analyze the given functions:

f(x) = (1 - cos(x)) / x^2

g(x) = x^2sin(1/x)

h(x) = sin(x) / x

By examining the given functions, we can see that the squeeze theorem can be applied with the inequalities involving g(x) and h(x) because g(x) and h(x) both approach 0 as x approaches 0.

Specifically, the following inequalities can be used with the squeeze theorem to find the limit of the function as x approaches 0:

0 ≤ |g(x)| ≤ |f(x)|

0 ≤ |h(x)| ≤ |f(x)|

These inequalities show that g(x) and h(x) are bounded by f(x) and approach 0 as x approaches 0. Therefore, we can use the squeeze theorem to conclude that the limit of g(x) and h(x) as x approaches 0 is also 0.

The application of the Squeeze Theorem can be demonstrated using g(x)=x^2 sin(1/x) bounded between -x^2 and x^2 as x approaches 0. Since the bounding functions approach 0, the limit of g(x) is also 0.

The Squeeze Theorem, also known as the Sandwich Theorem, is a concept in calculus which states if a function f(x) is 'squeezed' between two other functions g(x) and h(x) for all x in an interval, and the limit of g(x) and h(x) at a point c is the same, then the limit of f(x) at c must also be the same.

Considering the functions in the question, it's possible that g(x)=x2sin(1/x) can be 'squeezed' between two appropriate functions for applying the Squeeze Theorem. One can create two bounding functions for g(x): -x2 ≤ g(x) ≤ x2, since sin(1/x) is bounded between -1 and 1. Therefore, as x approaches 0, both bounding functions approach 0, hence by the Squeeze theorem, the limit of g(x) as x approaches 0 is also 0.

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

The probability that exactly two out of the five randomly selected trucks have defective brakes is approximately 0.3456, or 34.56%.

To calculate the probability that two out of five randomly selected trucks have defective brakes, we need to use the concept of combinations and the probability of selecting a truck with brake problems.

We know that there are 10 trucks in total and 4 of them have brake problems, we can first calculate the probability of selecting a truck with a brake problem.

The probability of selecting a truck with a brake problem is given by:

P(defective truck) = Number of defective trucks / Total number of trucks

P(defective truck) = 4 / 10 = 0.4

Next, we need to calculate the probability of selecting exactly two defective trucks out of the five trucks tested. We can use the binomial probability formula for this calculation:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

where:

P(X = k) is the probability of exactly k successes,

n is the total number of trials (number of trucks tested),

k is the number of successes (number of defective trucks),

p is the probability of success (probability of selecting a truck with brake problems), and

C(n, k) is the number of combinations of n items taken k at a time.

In this case, we have n = 5 (five trucks tested), k = 2 (two defective trucks), and p = 0.4 (probability of selecting a truck with brake problems).

Using the formula, we can calculate the probability:

P(X = 2) = C(5, 2) * 0.4² * (1-0.4)⁽⁵⁻²⁾

P(X = 2) = 10 * 0.4² * 0.6³

P(X = 2) = 10 * 0.16 * 0.216

P(X = 2) = 0.3456

Therefore, the probability that exactly two out of the five randomly selected trucks have defective brakes is approximately 0.3456, or 34.56%.

The change in equilibrium real GDP is B220.

To calculate the change in equilibrium real GDP resulting from an increase in autonomous investment, we need to use the expenditure-output model. In this model, equilibrium real GDP (Y) is determined by the aggregate expenditure (AE), which is the sum of consumption (C), investment (I), government spending (G), and net exports (NX). The equation is:

Y = AE = C + I + G + NX

Given the information provided, let's calculate the initial equilibrium real GDP (Y) using the given values:

C = 80 + (9/10)Y

DI = 1800

G = 1600

TR = 10

T = (1/3)Y

Substituting the values into the equation:

Y = (80 + (9/10)Y) + 1800 + 1600 + 10 - (1/3)Y

Simplifying the equation:

Y = 3490 + (5/6)Y

Multiplying through by 6 to remove the fraction:

6Y = 6(3490) + 5Y

6Y = 20940 + 5Y

Y = 20940

The initial equilibrium real GDP is 20940.

Now, let's calculate the equilibrium real GDP after the B220 increase in autonomous investment (ΔI):

Y' = Y + ΔI

Substituting the values:

Y' = 20940 + B220

Calculating the change in equilibrium real GDP:

Change in Y = Y' - Y

Change in Y = (20940 + B220) - 20940

Change in Y = B220

The change in equilibrium real GDP is B220.

A Southern Pacific rattlesnake is more likely to be longer than 43.6 inches.

To calculate the probability of a rattlesnake having a length greater than 43.6 inches, we need to find the standard score (z-score) of 43.6 inches for each species and then use a standard normal table to find the corresponding probability.

The formula for the standard score is:

\($z = \frac{x - \mu}{\sigma}$\) where,

For Great Basin rattlesnakes:

\($\mu\) = 40 inches

\($\sigma\) = 7.2 inches

So,

\($z = \frac{43.6 - 40}{7.2} = 0.5$\)

Using a standard normal table, we find that the probability of a Great Basin rattlesnake having a length greater than 43.6 inches is approximately 0.306.

For Southern Pacific rattlesnakes:

\($\mu\) = 40 inches

\($\sigma\) = 10.8 inches

So,

\($z = \frac{43.6 - 40}{10.8} = 0.333$\)

Using a standard normal table, we find that the probability of a Southern Pacific rattlesnake having a length greater than 43.6 inches is approximately 0.379.
