Which of the following statements is false? a. InputStream and OutputStream are abstract classes for performing byte-based I/O.

Bond [772]

Answer:

The answer is "Option b".

Explanation:

Tubes were streams among processes, that are interconnected. It is coordinated ways to communicate between threads, that's why the only option b is wrong, and the correct choice can be defined as follows:

In option a, the byte-based I/O the input and output stream abstract class is used, that's why it correct.
In option c, It is used to provide additional functionality, that's why it correct.
In option d, It is used to provide the text output.

Which is a real-world example of a procedure?

Romashka [77]

Answer:

Go out to get some milk

Explanation:

Almost anything we do in life is framed in a procedure, from making popcorn, to driving a car, to pay for the bus, to go out to get some milk, but we don't think about those in everyday life, because we are so used to them that we do them instinctively. Anything that implies doing specific actions in a specific order to obtain a specific result.

Procedure to get milk

Verify if you wear appropriate clothes to go outside

- If not, dress properly

Go out of your house (lots of mini procedures included here, like go to the door, open the door, get out, close and lock the door behind you, and so on)

Go to the store

Find milk in the shelf and take it to the cash registry

Pay for the milk

Go back home

Re-enter the house

Undress if necessary

Put milk in the fridge.

More obvious examples could be the fire emergency procedure or the pre-lift off check list for a plane.

the volume of two similar solids are 1080cm and 1715cm .if the curved surface area of the smaller cone is 840cm .fond the curved

gavmur [86]

Answer:

$A_{big} = 1143.33cm^2$

Explanation:

The given parameters are:

$V_{small} = 1080$

$V_{big} = 1715$

$C_{small} = 840$

Required

Determine the curved surface area of the big cone

The volume of a cone is:

$V = \frac{1}{3}\pi r^2h$

For the big cone:

$V_{big} = \frac{1}{3}\pi R^2H$

Where

R = radius of the big cone and H = height of the big cone

For the small cone:

$V_{small} = \frac{1}{3}\pi r^2h$

Where

r = radius of the small cone and H = height of the small cone

Because both cones are similar, then:

$\frac{H}{h} = \frac{R}{r}$

and

$\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}$

$\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}$

Substitute values for Vbig and Vsmall

$\frac{1715}{1080} = \frac{R^2H}{r^2h}$

Recall that: $\frac{H}{h} = \frac{R}{r}$

So, we have:

$\frac{1715}{1080} = \frac{R^2*R}{r^2*r}$

$\frac{1715}{1080} = \frac{R^3}{r^3}$

Take cube roots of both sides

$\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}$

Factorize

$\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}$

$\sqrt[3]{\frac{343}{216}} = \frac{R}{r}$

$\frac{7}{6} = \frac{R}{r}$

The curved surface area is calculated as:

$Area = \pi rl$

Where

$l = slant\ height$

For the big cone:

$A_{big} = \pi RL$

For the small cone

$A_{small} = \pi rl$

Because both cones are similar, then:

$\frac{L}{l} = \frac{R}{r}$

and

$\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}$

$\frac{A_{big}}{A_{small}} = \frac{RL}{rl}$

This gives:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}$

Recall that:

$\frac{L}{l} = \frac{R}{r}$

So, we have:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}$

$\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2$

Make $A_{big}$ the subject

$A_{big} = (\frac{R}{r})^2 * A_{small}$

Substitute values for $\frac{R}{r}$ and $A_{small}$

$A_{big} = (\frac{7}{6})^2 * 840$

$A_{big} = \frac{49}{36} * 840$

$A_{big} = \frac{49* 840}{36}$

$A_{big} = 1143.33cm^2$

Hence, the curved surface area of the big cone is 1143.33cm^2

Choose the term to complete the sentence.

netineya [11]

Answer:

raster

Explanation:

-> A raster image consists of a grid of colored pixels.

To choose our answer we can look at the definition for each of the options:

[✘] wireframe - "a skeletal three-dimensional model in which only lines and vertices are represented"

[✘] vector - "denoting a type of graphical representation using straight lines to construct the outlines of objects"

[✔] raster - "a rectangular pattern of parallel scanning lines followed by the electron beam on a television screen or computer monitor'

[✘] rendering - "the processing of an outline image using color and shading to make it appear solid and three-dimensional"

(All definitions are quoted from Oxford Languages)

-> Based on these definitions, raster makes the most sense

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
