Given the following class definition and the variable declaration:

class employee
char *name;
long id; }
class manager {
employee empl;
char* rank; } x

Which of the following assignment statement is correct?

a. x.empl->id = 12345;
b. x.id = 12345;
c. x->id = 12345;
d. x.empl.id = 12345;

Answers

Answer 1

Answer:

The answer is "Option d".

Explanation:

In the above-given code, two-class is defined that is "employee and manager", in which the first class "employee" defines two variables that are "name, id". In this name is pointer type character and id is a long type variable.

In the second class "manager" one variable "rank" and the employee object is created. In this class, the rank variable is a pointer type character, and outside this class, a reference "x" is created.

In this code, we use both class object that uses the "employee" class variable that is id to hold value in it.

, , and angle x and angle y are both in the first quadrant.

Answers

Answer:

[tex]\tan(x+y) = 3.73[/tex]

Explanation:

The missing part of the question are:

[tex]\sin(x) = \frac{1}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]

Required

[tex]\tan(x + y)[/tex]

First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]

We have:

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So:

[tex](1/2)^2 + \cos^2(x) = 1[/tex]

Collect like terms

[tex]\cos^2(x) = 1 - (1/2)^2[/tex]

[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]\cos^2(x) = \frac{4-1}{4}[/tex]

[tex]\cos^2(x) = \frac{3}{4}[/tex]

Square roots of both sides

[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

Similarly,

[tex]\sin^2(y) + \cos^2(y) = 1[/tex]

So:

[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]

[tex]\sin^2(y)+ (2/4) = 1[/tex]

[tex]\sin^2(y)+1/2 = 1[/tex]

Collect like terms

[tex]\sin^2(y) = 1 - 1/2[/tex]

Take LCM

[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]

[tex]\sin^2(y) = \frac{1}{2}[/tex]

Square roots of both sides

[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]

Rationalize

[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

So, we have:

[tex]\sin(x) = \frac{1}{2}[/tex]           [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]        [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]

[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]

Rewrite as:

[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]

[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]

Rationalize

[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]

Similarly

[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]

[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]

[tex]\tan(y) = 1[/tex]

Lastly,

[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]

Combine fractions

[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]

Cancel out 3

[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]

Using a calculator

[tex]\tan(x+y) = 3.73[/tex]

A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures?


please help me figure this out I am so confused

Answers

The corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures is: 155 kHz.

Given the following data:

Period = 645 μs

Note: μs represents microseconds.

Conversion:

1 μs = [tex]1[/tex] × [tex]10^{-6}[/tex] seconds

645 μs = [tex]645[/tex] × [tex]10^{-6}[/tex] seconds

To find corresponding frequency of this sinewave, in kHz;

Mathematically, the frequency of a waveform is calculated by using the formula;

[tex]Frequency = \frac{1}{Period}[/tex]

Substituting the value into the formula, we have;

[tex]Frequency = \frac{1}{645\; * \;10^{-6}}[/tex]

Frequency = 1550.39 Hz

Next, we would convert the value of frequency in hertz (Hz) to Kilohertz (kHz);

Conversion:

1 hertz = 0.001 kilohertz

1550.3876 hertz = X kilohertz

Cross-multiplying, we have;

X = [tex]0.001[/tex] × [tex]1550.39[/tex]

X = 155039 kHz

To 3 significant figures;

Frequency = 155 kHz

Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.

Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.
