Step 1: Define
f(x) = 1/3x + 5
f(3) is x = 3
Step 2: Evaluate
Substitute: f(3) = 1/3(3) + 5Multiply: f(3) = 1 + 5Add: f(3) = 6Consider the function given below: (defun things (x) (if (null x ) '() (if (>(carx) 10) (cons(+(carx) 1) (things (cdrx))) (cons (- (car x) 1) (things (codr x)) ) 1 ) 1 Show the evolution resulting from the following call: USP> (things '(11-2 31))
Answers
The evolution of the function call (things '(11 -2 31)) is as follows:
(things '(11 -2 31)) -> (things '(-2 31)) -> (things '(31)) -> (things '()) -> '() the final result of the given call is '().
The given function is a recursive function called "things" that takes a list as input. It checks if the list is empty (null), and if so, it returns an empty list. Otherwise, it checks if the first element of the list (car x) is greater than 10. If it is, it adds 1 to the first element and recursively calls the "things" function on the rest of the list (cdr x). If the first element is not greater than 10, it subtracts 1 from the first element and recursively calls the "things" function on the rest of the list. The function then returns the result.
Now, let's see the evolution resulting from the call (things '(11 -2 31)):
1. (things '(11 -2 31))
Since the list is not empty, we move to the next if statement.
The first element (car x) is 11, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.
The recursive call is (things '(-2 31)).
2. (things '(-2 31))
Again, the list is not empty.
The first element (car x) is -2, which is not greater than 10, so we subtract 1 from it and recursively call the "things" function on the rest of the list.
The recursive call is (things '(31)).
3. (things '(31))
The list is still not empty.
The first element (car x) is 31, which is greater than 10, so we add 1 to it and recursively call the "things" function on the rest of the list.
The recursive call is (things '()).
4. (things '())
The list is now empty, so the function returns an empty list.

As diversification increases, the total variance of a portfolio approaches _____.A. 0B. 1C. idiosyncratic riskD. systematic risk
Answers
The correct answer is A. 0. As diversification increases, the total variance of a portfolio approaches zero.
As diversification increases, the total variance of a portfolio approaches 0, which means that the portfolio becomes less risky. This occurs because diversification spreads the risk across multiple assets, reducing the impact of any single asset on the portfolio's overall performance. The reduction in risk is due to the fact that some assets in the portfolio may perform well while others may not, but the negative performance of some assets is compensated by the positive performance of others, leading to a lower overall portfolio variance. Therefore, option A is the correct answer.
Diversification is an investment strategy that involves spreading an investor's portfolio across different assets, such as stocks, bonds, real estate, and commodities, with the aim of reducing overall risk.

Answers
Answer:
B) x = 8\(\sqrt{3}\) ; y = 4\(\sqrt{3}\)
Step-by-step explanation:
in a 30-60-90° triangle the sides, respectively, are in the ratio of
1 : \(\sqrt{3}\) : 2
we can find 'x' by creating this proportion:
12/\(\sqrt{3}\) = x/2
cross-multiply to get:
\(\sqrt{3}\)x = 24
x = 24/\(\sqrt{3}\)
we can simplify this by 'rationalizing the denominator' which is to
multiply numerator and denominator by \(\sqrt{3}\) to get:
(24\(\sqrt{3}\))÷3, which is 8\(\sqrt{3}\)
we know that side 'y' is half that of side 'x'
therefore y = 4\(\sqrt{3}\)

Randy has begun selling portraits of his pet rocks. He estimates the cost of producing x portraits is given by the function C(x)=1000+25x−0.1x 2
. a. Find the fixed costs. What factors could be contributing to this? b. Find the average cost for producing 20 portraits. c. Find and interpret the marginal average cost for x=20.
Answers
The fixed cost can be attributed to expenses such as rent, salaries of staff, depreciation of machinery, and other overhead costs that do not depend on the level of production.
a) Fixed costs refer to those costs that do not change with a change in production.
It is the amount that Randy would have to pay even if he did not sell a single portrait.
Therefore, the fixed cost in this case is the constant value, i.e., $1000.
The fixed cost can be attributed to expenses such as rent, salaries of staff, depreciation of machinery, and other overhead costs that do not depend on the level of production.
b) Average cost (AC) is the cost per unit of production. It is found by dividing the total cost by the number of units produced. When 20 portraits are produced, the cost of production is:
C (20) = 1000 + 25 (20) - 0.1 (20)2
= 1000 + 500 - 40
= $1460
Average Cost = Total cost/ Number of portraits
= 1460/20 = $73
c) The marginal average cost refers to the additional cost incurred for producing one additional unit of the product. It is given by the first derivative of the average cost function, i.e., dAC(x) / dx.
Marginal Average Cost when x=20 is given by the first derivative of the average cost function:
AC(x) = (1000+25x-0.1x²) / x
= 1000/x + 25 - 0.1x
Marginal Average Cost = dAC(x) / dx
= -1000/x² - 0.1
= -1000/20² - 0.1
= -0.6
Interpretation:
When Randy produces the 20th portrait, the marginal average cost is $-0.6, which implies that the average cost of production will decrease if he produces one additional portrait. This is because the cost of producing that additional unit is less than the current average cost.
Therefore, Randy can maximize his profit by producing more portraits as long as the marginal cost is less than the selling price.

Answers
A sphere thrown upward at a 45-degree angle to the horizontal in a classroom elastically bounces off the ceiling while still rising
At time t = 0, a sphere is launched with an initial velocity at a 45-degree angle to the horizontal in a classroom. The sphere follows a parabolic trajectory as it rises due to the upward component of its initial velocity and experiences the downward pull of gravity. While the sphere is still ascending, it reaches the ceiling and collides with it.
During the elastic collision, the sphere's motion is reversed. It rebounds off the ceiling, changing its direction but maintaining its kinetic energy. As a result, the sphere starts descending with the same speed it had before the collision but in the opposite direction. The angle of descent will also be 45 degrees to the horizontal, mirroring the angle of the initial launch.
Throughout the entire process, neglecting air resistance, the total mechanical energy of the sphere is conserved since the collision with the ceiling is elastic.
