puteri [66]

Answer:

In Python:

def MPH(miles,minutes):

mph = round(60 * miles/minutes,1)

return mph

miles = float(input("Miles: "))

minutes = float(input("Minutes: "))

if miles>0 and minutes>0:

print("MPH: ",MPH(miles,minutes))

else:

print("Positive inputs only")

Explanation:

This defines the function

def MPH(miles,minutes):

This calculates mph rounded to 1 decimal place

mph = round(60 * miles/minutes,1)

This returns the calculated mph

return mph

The main begins here

This gets input for miles

miles = float(input("Miles: "))

This gets input for minutes

minutes = float(input("Minutes: "))

If miles and minutes are positive

if miles>0 and minutes>0:

This calls the MPH function

print("MPH: ",MPH(miles,minutes))

If otherwise, this prompts the user for positive inputs

else:

print("Positive inputs only")

Answer:

Here’s one!

Given [math]R[/math], the radius of the circle.

Let [math]N,D\leftarrow 0[/math]

Repeat until [math]D[/math] is large enough (about 1,000,000)

[math]x,y\leftarrow U[0,1][/math]

If [math]x^2 + y^2\le 1[/math] then [math]N\leftarrow N+1[/math]

[math]D\leftarrow D+1[/math]

[math]P\leftarrow\frac{8NR}{D}[/math]

Return [math]P[/math]

[math]U[0,1][/math] is a uniform random number in the range [math][0,1][/math].

What is the first thing you should do when you discover a computer is infected with malware? The second thing?

Goshia [24]

Answer:

Quarantine the computer.

Explanation:

Malware can be characterized with negative software capable of causing various damages to a computer, such as theft of data and information, in addition to damage to devices.

In order to avoid having your computer infected with malware, it is essential to have installed reliable malware-checking software, in addition to taking all appropriate security measures when accessing the internet and never clicking on unknown or suspicious links.

Therefore, when realizing that the computer has been infected by malware, it is necessary to quarantine the computer and immediately disconnect from a network so that it does not infect other computers. The quarantine acts as an action where the infected file is moved to an encrypted folder where the malware cannot be executed and spread by the operating system.
