An interface does not have ____.

Computers and Technology

5 0

Answer:

B - instance fields

Explanation:

Fields/variables declared within interfaces are by default final, public or static and hence will not be considered as an instance variable/field but a class variable. Although interfaces can be used to define instance methods, they will never have instance variables.

[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

Dawn needs to insert a macro into a Word document. Where can she find the Insert Macro dialog box?
amid [387]

Answer:

Developer tab

Explanation:

Inserting the Macro dialog box can be confusing for many people because the "Developer tab," where it can be found, is <em>hidden by default</em> in Microsoft Word. In order to add this to the ribbon, all you have to do is to go to the File tab, then click Options. After this, click Customize Ribbon. Under this, choose Main Tabs, then select the Developer check box. The Developer tab will then become visible. You may now insert a macro.

Which criterion can be used to select the appropriate type of network media for a network?
OverLord2011 [107]

There are various kinds of network media and each one of them has different features and benefits. Some have different characteristics and not all of them are meant to perform the same purpose. While choosing network media, a number of criteria must be met. These criteria include:

The distance the selected medium can successfully carry a signal.

The environment where the selected medium is to be installed

Explanation:

The distance the selected medium can successfully carry a signal – The type of network media you choose depends on the distance it can cover before you install signal boosters or repeaters. Repeaters are used to regenerate signals that are required to cover greater distances. A UTP cable as compared to fiber is more prone to interference like noise and the distance it covers before a signal repeater is installed is shorter. Fiber cable is considered the best for distances as it can cover longer distances.

Environment should also be considered when choosing network media - If your network is setup in a place where there is too much electromagnetic field being generated, then you may be required to purchase fiber optic cables. Fiber optics are immune to such interference.
