Answer:
The minimum umber of multiplication operations needed to compute is 1242.
Explanation:
Solution
Given that:
Now,
(A1*(A2*A3))*(A4A5)
Thus
A2*A3 = 7*30*2 = 420 operations. It will create 7*2 matrix.
A1*(A2*A3) = 3*7*2 = 42 operations. It will create 3*2 matrix
A4*A5 = 2*10*30 = 600 Operations. It will create 2*30 matrix.
(A1*(A2*A3))*(A4A5) = 3*2*30 = 180 operations. It will create 3*30 matrix
Hence
The total number of multiplications are is given below
420+42+600+180 = 1242
Answer:
B. Methods and occasionally final attributes
Explanation:
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.
Answer:
Another way to block all inbound packets is to use the firewall layer of the circuit.
Explanation:
The firewall circuit layer is a firewall containing a table with four fields, mainly such as source port, destination port, source IP address, and destination IP address.
They are containing mainly the addresses or the ports that need to be blocked.
So we want to block all inbound packets, and also set the source port to 23 while the rest is set to zero, meaning that all inbound packets are blocked.
