Answer:

The output is 20

Explanation:

Given:

numA = 2

for count in range(5,8):

numA = numA + count

print(numA)

Required:

Determine the output

The first line of the program initializes numA to 2.

The next iteration sum up integers from 5 to 7 (i.e. 8 - 1) to the initialized value of numA

So, numA becomes

$numA = 2 + 5 + 6 + 7$

$numA = 20$

Hence, the output is 20

Answer:

Explanation:

assuming the print statement is not indented, the program effectively calculates 2+5+6+7.

The range(...) is excluding the end value (8 in this case).

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

Which IDEs support multiple high-level programming languages? Select all that apply.

rewona [7]

Answer:

The correct answer to this question is given below in the explanation section.

Explanation:

This question is about integrated development environments (IDEs) that support multiple high-level programming languages.

All mentioned IDEs such as Eclipse, Visual Studio, and Xcode support multiple high-level programming languages except Linux.

Using Eclipse, you can do Java programming easily and can build Java-based programs, and also you can do android programming in Eclipse while importing required android settings and libraries. Visual Studio is a Microsoft IDE, in which you can build desktop, web, and mobile, and windows phone app easily using high-level programming. Xcode is an integrated development environment for macOS containing a suite of software development tools developed by Apple for developing software for macOS, iPadOS, iOS, watchOS, and tvOS.

While Linux is not an IDEs, it is an open-source operating system based on Linux kernel.

Since the value we want to receive is either true or false, it makes the most sense to use:

EastWind [94]

Answer:

Logical Expressions

Explanation:

The expressions that have logical statements which could be "true or false" are known as logical expressions. These types of expressions are also known as Boolean Expressions.

These expression are used in computer programming. The purpose of these expressions in programming is to make a decision that could be based on different conditions. These conditions could be true or false. This is the main reason that. logical expression makes best sense for values received in true or false.
