ven int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 5

monitta

Answer:

Following are statement is given below

int k=1,total=0; // variable declaration

while(k<50) // iterating the while loop

{

total=total+k*k;// calculating the square

k=k+1; // increments the value of k by 1

}

Explanation:

Following are the description of Statement.

Declared a variable "total" and "k" of the "integer " type initialized the total to 0 and "k" to 1.
Iterating the while loop for less then 50 .In this loop, we calculating the sum of square of first 50 number in the "total" variable .
After that increment the value of "k" variable by 1 to execute the loop less then 50 .

[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

Universal Windows Platform is designed for which Windows 10 version?

Naddika [18.5K]

Universal Windows Platform is an open source API created by Microsoft and first introduced in Windows 10. The purpose of this platform is to help develop universal apps that run on Windows 10, Windows 10 Mobile, Xbox One and HoloLens without the need to be re-written for each. It supports Windows app development using C++, C#, VB.NET, and XAML. The API is implemented in C++, and supported in C++, VB.NET, C#, F# and JavaScript. Designed as an extension to the Windows Runtime platform first introduced in Windows Server 2012 and Windows 8, UWP allows developers to create apps that will potentially run on multiple types of devices.
