Consider a satellite orbiting the earth. Its position above the earth is specified in polar coordinates. Find a model-view matri

x that keeps the viewer looking at the earth. Such a matrix could be used to show the earth as it rotates.

Two technicians are discussing engine valve timing. Technician A says that the optimum valve timing is found through experimenta

nordsb [41]

The answer is B. A only. The optimum valve timing is found through experimentation using an engine dynamometer. The timing of the opening and closing of the valves is called valve timing. So the use of dynamometer measures the power output of a machine that is why it can measure the optimum valve timing.

A variable must have its type declared but it is not required to be initialized prior to first use.

AnnZ [28]

Answer:

a) TRUE.

Explanation:

The statement is true.We can declare a variable but not initialize it there we can initialize it afterwards when we want to use.On declaring the variable type it tells the compiler to reserve the memory according to the size required for the data type.When we initialize the memory is allocated to that variable.

How many different messages can be transmitted in n microseconds using three different signals if one signal requires 1 microsec

SIZIF [17.4K]

Answer:

a_{n} = 2/3 . 2^n + 1/3 . (-1)^n

Explanation:

Let a_{n} represents number of the message that can transmitted in <em>n </em>microsecond using three of different signals.

One signal requires one microsecond for transmittal: a_{n}-1

Another signal requires two microseconds for transmittal: a_{n}-2

The last signal requires two microseconds for transmittal: a_{n}-2

a_{n}= a_{n-1} + a_{n-2} + a_{n-2} = a_{n-1} + 2a_{n-2}, n ≥ 2

In 0 microseconds. exactly 1 message can be sent: the empty message.

a_{0}= 1

In 1 microsecond. exactly 1 message can be sent (using the one signal of one microseconds:

a_{0}= 1

2- Roots Characteristic equation

Let a_{n} = r^2, a_{n-1}=r and a_{n-2}= 1

r^2 = r+2

r^2 - r - 2 =0 Subtract r+6 from each side

(r - 2)(n+1)=0 Factorize

r - 2 = 0 or r +1 = 0 Zero product property

r = 2 or r = -1 Solve each equation

Solution recurrence relation

The solution of the recurrence relation is then of the form a_{1} = a_{1 r^n 1} + a_{2 r^n 2} with r_{1} and r_{2} the roots of the characteristic equation.

a_{n} =a_{1} . 2^n + a_{2}.(-1)"

Initial conditions :

1 = a_{0} = a_{1} + a_{2}

1 = a_{1} = 2a_{1} - a_{2}

Add the previous two equations

2 = 3a_{1}

2/3 = a_{1}

Determine a_{2} from 1 = a_{1} + a_{2} and a_{1} = 2/3

a_{2} = 1 - a_{1} = 1 - 2 / 3 = 1/3

Thus, the solution of recursion relation is a_{n} = 2/3 . 2^n + 1/3 . (-1)^n

write pseudocode to represent the logic of a program that allows the user to enter two values. The program outputs the sum of an

valkas [14]

The pseudocode representing the above described logic of a program is:

start

input num1

input num2

set product = num1*num2

output product

stop

See the related flow chart is attached.

<h3>What is a pseudocode?</h3>

Pseudocode is a precise yet comprehensible explanation of what a computer program or algorithm must perform, written in normal language rather than programming language.

Pseudocode is occasionally used as a detailed phase in the development of a program.

Which of the following is an example of a Syntax Error?

quester [9]

Answer:

The correct answer is: "The program does not run at all."

Explanation:

The rules to write a program in any language are called syntax. The error in syntax of a language is called syntax error. Syntax errors are usually detected during the compilation of the program. The program cannot be run untill all syntax errors are removed.

So,

The correct answer is: "The program does not run at all."
