The explanation for each condition of the question is given below in which the activation record for the function is deallocated for Option (A).
What is an activation record?
Information required for just one execution of a procedure is managed by an activation record. When a procedure is called, an activation record is pushed into the stack, and it is popped when the control is returned to the calling function.
From the question, Languages typically group all activation-specific function validation under the umbrella of an activation record.
Whenever the block is entered, extend the function activation record.
a. fun f x = x + 1;
In this situation, the activation record concludes after the function "f" exits.Extend the function activation record if the block is entered; otherwise, revert.The activation record was terminated after execution at x=x+1. So, we. The activation record has to be reallocated.Because f(x)=x+1.11f is called, the local function is returned. The activation record is therefore deallocated.b. fun f x = y =>x y;
Take fun f
x=fun y
x+y
Here, f(x) and f are two functions (y).The execution of f(x) requires f(y).Therefore, until f(x) and f(y) is performed, the activation record will remain active. When the control returns to the first function, the activation record is exited.Therefore, during the function return, we need to reallocate the activation record.c. fun.f x = fn y => y+ 1;
fun f
x => fn
y => y+1
In this case, the activation record is expanded to include the second function, f(y), whose execution is reliant on f(x).The record will remain active till the execution of the two functions.After the activation record has been allocated, it is reactivated as the method returns.d. fun f x = map ~ x
Here, the map is used to connect the list to the function f(x) and the activation record is for the function f(x). As a result, the activation record is changed independently and then returned.As a result, a new activation record is not necessary.To learn more about an activation record

Joni is mistaken because she applied the compounding rate formula rather than just the simple interest rate equation, which is incorrect. $231.53 will belong to her.
Explain the term compounded annually?The equation A=P(1+r)t can be used to calculate the amount A you would have after t years if you deposit P dollars together in savings account including an annual interest rate of r and also the interest is compounded annually.The $200 was deposited by Joni into an account that earned interest at a 5% annual compound rate.
Joni calculated and she'll have a final balance of $230 after three years.
The steps are as following,
P = 200, r = 5, t = 3I = 200*0.05* 3I = 3030 + 200 = 230Because Joni employed the simple interest rate method instead of the compound interest rates formula, she is mistaken $231.53 will belong to her.
The yearly compound interest rate if 5% is stated above.
As a result, she ought to have used the compound interest calculation when calculating.
A = P(1 + r/n)∧(nt)

The number of days that the second voyage last's is 480 days.
Given,
The discrepancy in the length of the two excursions, we are asked to determine how many days the second voyage lasted.
We initially assign variables in order to overcome this issue. Let the duration of the first cruise be f days and the duration of the second expedition be s days.
We are aware that the first journey lasted 43 days longer than the second.
In mathematics, f = 43 plus s. (I)
The cumulative duration of the two journeys was 1003 days. Mathematically:
f + s = 1003........(ii) (ii)
We transform I into ii
43 + s + s = 1003
43 +2s = 1003

nine new employees, two of whom are married to each other, are to be assigned nine desks that are lined up in a row. if the assignment of employees to desks is made randomly, what is the probability that the married couple will have adjacent desks? (round your answer to the nearest tenth of a percent.)
The probability that the married couple will have adjacent desks is 0.22.
Fundamental Principle of Counting, also called the counting rule, is the method to count how many ways multiple independent events can occur.
Thus, by Fundamental Principle of Counting, the number of possible arrangements where the married coupe has adjacent desks is 80640.
= 8 x 7! x 2
= 80640
Ans the total number of possible arrangements is 362880.
= 9!
= 362880
Probability is defined as the likeliness of an event to occur. The probability of any event to occur ranges from 0 to 1, and the sum of all the probabilities of all the events happening is 1.
probability = desired outcome / total outcomes
probability = 80640/362880

you have 2,000 feet of fencing to enclose a rectangular pasture. one side of the pasture is up against a river. what is the maximum area you could enclose?
Maximum area to enclose a rectangular pasture with one side up against a river is equal to 500,000 square feet.
As given in the question,
Let 'l' be the length of the rectangular pasture
And 'w' be the width of the rectangular pasture
Condition:
One side of the pasture is up against a river
Perimeter of the rectangular pasture with one side up against river = l + 2w
⇒ 2000 = l + 2w
⇒ l = 2000 - 2w
Area of the rectangular pasture
=( 2000 - 2w )( w )
= - 2 ( w² - 1000w )
= -2( w² - 1000w + 250000 - 250000 )
= -2 ( w - 500 )² + 500, 000
Maximum area is at w = 500
Maximum area is 500,000
Therefore, the maximum area of the given rectangular pasture is 500,000 square pasture.

On the image you can see the different pieces of the function, and on the right the domain of each of the pieces.
The first part works for all the values smaller than -4 and x = -4.
So if we want to evaluate the function in x = -7, we need to use that piece:
f(-7) = |-7 + 5| - 9 = -7
And the second piece works on the interval (-4, 1], so to evaluate in x = 1 we need to use that piece.
f(1) = -1³ - 3*1 = -4

What is the magnitude?The magnitude or size of a mathematical object determines whether it is larger or smaller than other objects of the same kind in mathematics.
Formally speaking, the magnitude of an object is the visible outcome of an ordering—of the class of objects to which it belongs.
So, the weight of the person will be:
The scale measures the passenger's normal upward force as it is applied by the floor.
When moving upward, the most force is generated (when starting an upward trip or ending a downward trip).
When there is a downhill acceleration, the normal force is at its lowest.
For any such circumstance:
∑F y =ma y becomes for starting +591N−mg=+ma and for stopping +391N−mg=−ma.
Where a stands for the acceleration's magnitude.
To get rid of a and find mg, add these two simultaneous equations:

The probability of obtaining between 70 and 82 tails is 0.2137, that is, option A.
Here, we are given that a fair coin is tossed 130 times.
Thus,
number of trials ⇒ n = 130
p = P(getting tails in a single toss) = 0.5
mean of a binomial distribution = np
= 130*0.5
= 65
variance = np(1-p)
= 65*0.5
= 32.5
standard deviation = sqrt(variance)
= sqrt(32.5)
= 5.7
Now, x = number of tails
X follows a normal distribution with mean 65 and variance 5.7
P(70 < x < 82)
= P( 69.5 < X < 82.5) [applying continuity correction]
= P[(69.5-65)/5.7 < Z < (82.5-65)/5.7)]
= P(0.79 < Z < 3.07)
= P(Z < 3.07) - P(Z < 0.79)
= 0.9989- 0.7852
= 0.2137
Thus, the probability of obtaining between 70 and 82 tails is 0.2137, hence, option A. .

If the equation of f(x) goes through (1, 4) and (4, 6), what points does f-1(x) go through?.
The positions through which the equation of f^-1(x) travels are: (4, 1), (6, 4)
What are equations?A mathematical statement called an equation is comprised of two expressions joined together with the equal sign.
A formula would just be 3x - 5 = 16, for instance.
When this equation is solved, we observe that the value of the variable x is 7.
So, (1, 4) and (4, 6) are points through which the equation of f(x) goes.
If the f (x) equation contains (x, y).
Therefore, the f^-1(x) equation is as follows: (y, x).
Here, the f (x) equation passes through the following points: (1, 4) and (4, 6).
So, (4, 1) and (6, 4) are the points through which the equation of f^-1(x) goes through.
Therefore, the positions through which the equation of f^-1(x) travels are:
(4, 1), (6, 4)
