The difference is B&D cause the B has the line but the D doesn't Okay now the C was developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs.C++ was developed by Bjarne Stroustrup in 1979 with C++'s predecessor "C with Classes".When compared to C++, C is a subset of C++.C++ is a superset of C. C++ can run most of C code while C cannot run C++ code.C supports procedural programming paradigm for code development.C++ supports both procedural and object oriented programming paradigms; therefore C++ is also called a hybrid language.C does not support object oriented programming; therefore it has no support for polymorphism, encapsulation, and inheritance.Being an object oriented programming language C++ supports polymorphism, encapsulation, and inheritance.In C (because it is a procedural programming language), data and functions are separate and free entities.In C++ (when it is used as object oriented programming language), data and functions are encapsulated together in form of an object. For creating objects class provides a blueprint of structure of the object.In C, data are free entities and can be manipulated by outside code. This is because C does not support information hiding. In C++, Encapsulation hides the data to ensure that data structures and operators are used as intended.C, being a procedural programming, it is a function driven language. While, C++, being an object oriented programming, it is an object driven language.C does not support function and operator overloading.C++ supports both function and operator overloading.C does not allow functions to be defined inside structures.In C++, functions can be used inside a structure.C does not have namespace feature.C++ uses NAMESPACE which avoid name collisions. A namespace is a declarative region that provides a scope to the identifiers (the names of types, functions, variables, etc) inside it. Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially when your code base includes multiple libraries. All identifiers at namespace scope are visible to one another without qualification. Identifiers outside the namespace can access the members by using the fully qualified name for each identifier. C uses functions for input/output. For example scanf and printf.C++ uses objects for input output. For example cin and cout.C does not support reference variables.C++ supports reference variables.C has no support for virtual and friend functions.C++ supports virtual and friend functions.C provides malloc() and calloc() functions for dynamic memory allocation, and free() for memory de-allocation.C++ provides new operator for memory allocation and delete operator for memory de-allocation.C does not provide direct support for error handling (also called exception handling)Hope this helps ☺

Which of the following is the complete solution to the equation? (X-10)(X+8)=0

guajiro [1.7K]

X-10 = 0 results in x = 10, and x + 8 = 0 results in x = -8.

The two solutions are x = 10 and x = -8

The number of flaws in a certain type of lumber follows a Poisson distribution with a rate of 0.45 per linear meter. What is the

lbvjy [14]

Answer:

So, the probability is P=0.0097.

Step-by-step explanation:

We know that the number of flaws in a certain type of lumber follows a Poisson distribution with a rate of 0.45 per linear meter.

We conclude that λ=0.45.

We use the Poisson formula:

$\boxed{P(X=k)=\frac{\lambda^k\cdot e^{-\lambda}}{k!}}$

We calculate the probability that a board 3 meters in length has no flaws. We get that k=3.

We calculate:

$P(X=3)=\frac{0.45^3\cdot e^{-0.45}}{3!}\\\\P(X=3)=0.0097\\$

So, the probability is P=0.0097.

Write down an (in)equality which describes the solid ball of radius 2 centered at (-2, 5, 2). It should have a form like ????2 ?

MissTica

$\text{We know that the euation of the sphere with radius r and centered at (h,k,l)}\\
\text{is given by:}\\
\\
(x-h)^2+(y-k)^2+(z-l)^2=r^2\\
\\
\text{here we have given a solid ball of radius 2 centered at }(-2, 5,2), \text{ so the }\\
\text{region of the ball will be all the area within the ball.}\\
\text{Hence the inequality that will describe the ball is give given by}$

$(x-(-2))^2+(y-5)^2+(z-2)^2\leq 2^2\\
\\
\Rightarrow (x+2)^2+(y-5)^2+(z-2)^2\leq 4\\
\\
\text{hence the required inequality that describes the ball is:}\\
\\
(x+2)^2+(y-5)^2+(z-2)^2-4\leq 0$
