Answer:

Option (3) is the correct answer of this question.

Explanation:

HCatalog makes available Hive metadata to users of other Hadoop applications, such as Pig, MapReduce and Hive. it offers interfaces for MapReduce and Pig so that users can read data from and write data to the Hive warehouse.
This means users don't have to care about where or in what format their data is stored. So we know this way that Hcatalog makes sure our data is secure.
Others option does not belong to Hcatalog so these options are incorrect .

Drag each statement to the correct location.

VMariaS [17]

Answer:

$(a)\ 222_{10} = DE_{16}$ --- True

$(b)\ D7_{16} = 11010011_2$ --- False

$(c)\ 13_{16} = 19_{10}$ --- True

Explanation:

Required

Determine if the statements are true or not.

$(a)\ 222_{10} = DE_{16}$

To do this, we convert DE from base 16 to base 10 using product rule.

So, we have:

$DE_{16} = D * 16^1 + E * 16^0$

In hexadecimal.

$D =13 \\E = 14$

So, we have:

$DE_{16} = 13 * 16^1 + 14 * 16^0$

$DE_{16} = 222_{10}$

Hence:

(a) is true

$(b)\ D7_{16} = 11010011_2$

First, convert D7 to base 10 using product rule

$D7_{16} = D * 16^1 + 7 * 16^0$

$D = 13$

So, we have:

$D7_{16} = 13 * 16^1 + 7 * 16^0$

$D7_{16} = 215_{10}$

Next convert 215 to base 2, using division rule

$215 / 2 = 107 R 1$

$107/2 =53 R 1$

$53/2 =26 R1$

$26/2 = 13 R 0$

$13/2 = 6 R 1$

$6/2 = 3 R 0$

$3/2 = 1 R 1$

$1/2 = 0 R1$

Write the remainders from bottom to top.

$D7_{16} = 11010111_2$

Hence (b) is false

$(c)\ 13_{16} = 19_{10}$

Convert 13 to base 10 using product rule

$13_{16} = 1 * 16^1 + 3 * 16^0$

$13_{16} = 19$

Hence; (c) is true

What is the inverse function of d(x ) = -2x - 6?

PtichkaEL [24]

Answer:

$-\frac{x}{2} - 3$

Explanation:

d(x) = -2x - 6

to find the inverse of a function, you need to follow these steps:

1. set d(x) = y

2. interchange the variables, so y becomes x and x becomes y

3. solve the equation for y

step 1: set d(x) = y

y = -2x -6

step 2: interchanging the variables

y = -2x - 6 turns into x = -2y - 6

step 3: solving for y

x = -2y - 6 < add 6 to both sides to get rid of it on the right

x + 6 = -2y < divide both sides by -2 to get y alone

x + 6 / -2 = $-\frac{x}{2} - 3$

-2y / -2 = y

$-\frac{x}{2} - 3$ = y

so the inverse of the function is $-\frac{x}{2} - 3$

Papessa [141]

Data sharing, maintaining security

Explanation:

Kristian is a cybersecurity professional. She is writing a book called The Door Toward Cybersecurity. Organizations should avoid any data sharing or exchange while servers are transmitting information. This will help organizations keep the information intact and maintain security. If any info or data shared when the servers are transmitting the info, then it may lead to the loss of security, and the information gets leaked. So it must be avoided to share while transmission of info using the servers.
