Answer:

6898

Explanation:

Given that 1AF2 is a hexadecimal number.

We have in hexadecimal, the digits are 0,1,2,3...9, A,B,C,D,E,F for the 16 digits used.

Using the above we say in the given number, we have

2 in units column

F in 16 column

A in 16 square column

and 1 in 16 cube column

Place value $= 2(1) +15(16)+10(16^2)+1(16^3)\\= 2+240+2560+4096\\=6898$

Hence 1AF2 = 6898 in decimal

Explain in details how Galen , a physician during the Middle Ages, expanded on Hippocrates' theory of the four humors and explai

NISA [10]

Answer:

Galen expanded on the Hippocrates' theory of humor by assigning personalities, moods, behaviors, and emotions to the four humors. He believed blood stood for sanguine personality, black bile for a melancholic personality, yellow bile for a choleric personality and phlegm for a phlegmatic personality.

Explanation:

Hippocrates put forward the theory of the four humors. According to the theory, the human body is made up of four substances: black bile, yellow bile, blood, and phlegm. A healthy human body is the product of a balance of among the four humors, while diseases results if there is an imbalance among the four humors.

Galen, a keen admirer of Hippocrates' ideas, further elaborated on this theory and believed that they affected personalities, moods, behaviors, and emotions.

The personalities assigned the four humors are as follows:

People with predominantly black bile are Melancholic (corresponding to the season of autumn dry and cold): They are very sensitive, and enjoy artistic pursuits.

People with predominantly yellow bile are Choleric (corresponding to the season of summer, dry and hot): They possess a passionate temperament, They have a lot of ambition, energy, drive, enormous vitality but are domineering and get angry quickly.

People with predominantly blood are Sanguine (corresponding to the season of spring, wet and hot): These people are confident, joyful, optimistic, expressive, confident, rational and sociable.

People with predominantly phlegm are Phlegmatic (corresponding to the season of winter, wet and cold): They are deep thinkers, fair, calm, very consistent, relaxed, and observant, willing to compromise, and hard workers.

What do you mean by real time system? Why real time system needs to response within limited time?

Anna11 [10]

Real time system means that the system is subjected to real time, i.e., response should be guaranteed within a specified timing constraint or system should meet the specified deadline. For example: flight control system, real time monitors etc.

Which of these is the most likely result if the internet download speed in your home is 25 Mbps?

sashaice [31]

Answer:

Streaming movies may stop to buffer

Explanation:

microphones have a set record limit, and games downloaded wont generate errors unless something in the code is wrong, printers don't really need to connect to internet to work except for some, and streaming movies buffer because as you are watching them it downloads the next few minutes.

[20 pts] Write the function rectangle(perimeter, area), which takes two positive integers, perimeter and area. It returns an int

MrRissso [65]

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
