L is a decidable language because the Turing machine accepts it.
L is a recognizable language if TM M recognizes it.
<h3>How do you know if a language is decidable?</h3>
A language is said to be decidable only when there seems to exists a Turing machine that is said to accepts it,
Here, it tends to halts on all inputs, and then it answers "Yes" on words that is seen in the language and says "No" on words that are not found in the language. The same scenario applies to recognizable language.
So, L is a decidable language because the Turing machine accepts it.
L is a recognizable language if TM M recognizes it.

Answer:
A and C are the only <u>legal</u> but unethical options
Insecurely attached infants who are left my their mothers in an unfamiliar setting often will Hold fast in their mothers in their return.
A. Hold fast in their mothers in their return
<u>Explanation:</u>
It is in the conscience of the infants to have the company of their parents no matter the place or time and do not generally like to be left alone. Moreover, the questions says, insecurely attached infants which further add up to this behavior.
The infant would not explore the surroundings due to lack of confidence in an unfamiliar setting. They would rather be uncomfortable and most probably weep the time until their mother arrives and hold fast on to them on their return.
Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
import math
def rectangle(perimeter, area):
l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4
l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4
l2_1 = area/l1_1
l2_2 = area/l1_2
print(l1_1,l2_1)
print(l1_2,l2_2)
if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:
return(int(max(l1_1,l2_1)))
elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:
return(int(max(l1_2,l2_2)))
else:
return(None)
Explanation:
- We import math to make basic operations
- We define the rectangle function that receives perimeter and area
- We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
- We calculate the second root of the quadratic equation for the same side (l1_2)
- We calculate the second side of the rectangle using the first root on w = a/h
- We calculate the second side of the rectangle using the second root on w= a/h
- We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
- If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
- if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
Answer:
ofstream asia("asiasales2009.txt"); //It is used to open asiasales2009.txt files with the asia objects.
ofstream europe("europesales2009.txt"); //It is used to open europesales2009.txt files with the europe objects.
ofstream africa("africasales2009.txt");
//It is used to open africasales2009.txt files with the africa objects.
ofstream latin("latinamericasales2009.txt");//It is used to open latinamericasales2009.txt files with the latin objects.
Explanation:
- The above code is written in the c++ language which is used to open the specified files with the specified objects by the help of ofstream class as described in the question-statements.
- The ofstream is used to open the file in the c++ programing language, so when a user wants to use the ofstream to open the file in written mode, then he needs to follow the below syntax--
ofstream object("file_name_with_extension");
