What is meant by cross section area?The area of a two-dimensional shape created when a three-dimensional object, like a cylinder, is cut perpendicular to a predetermined axis at a point is known as the cross-sectional area. For instance, a cylinder's cross-section is a circle when it is cut parallel to the base.Cross section is defined in the Britannica Dictionary. 1.: a perspective or illustration that depicts how something appears on the inside after a cut has been made across it. A thorough cross-section of the human brain is [counted]. Conic sections are some of the most well-known cross sections. Conic sections are made by cutting a right cone in several ways. Conic sections come in four different shapes: circles, ellipses, parabolas, and hyperbolas.

When assembling a career portfolio, what should a student do before assessing their work?
A.
consider the types of jobs they will likely apply for
B.
delete or throw away projects that are not good enough to include
C.
assemble the documents and files in the order they were created
D.
design a cover for a physical portfolio or a landing page for an electronic portfolio
Please don't guess.
Answer:
A.
Consider the types of jobs they will apply for.
Explanation:
It's critical to consider the types of jobs the student will apply for before assessing their work to know which information will be the most predominant and favorable to your employer.
Errors can be syntax errors or logic errors (the code works, but not as intended). In the Guess My Number game, there is a lower limit and an upper limit for the range of possible numbers to guess. If the lower limit were exclusive and the upper limit inclusive, which expression would properly generate values for the secret number?
(int)(Math.random() * (upper − lower + 1) ) + lower
(int)(Math.random() * (upper − lower) ) + lower + 1
(int)(Math.random() * (upper − lower + 1) ) + lower - 1
Errors can be syntax errors or logic errors (the code works, but not as intended) is option A: (int)(Math.random() * (upper − lower) ) + lower
What is the syntax errors about?The phrase that would correctly provide results for the secret number if the lower limit were inclusive and the upper limit exclusive is Option A
Note that we cannot increase the lower limit by one because it is INCLUSIVE. Additionally, the Math.random() function returns a result between [0,1[ that satisfies our requirements (meaning the 0 is included, but not the 1).
Therefore, We'll be flawless if the (int) caster returns only the integer component after rounding down the result.

A student wants to create an Android Application to help a motorist to approximate the cost of a journey
by road. The app should enable the user to enter the length of the journey in Kilometres, the amount fuel
that the vehicle uses per kilometre and the cost of fuel per litre. The app should then calculate the total
amount that will be spent on fuel for the journey.
Sketch the interface for the activity that can be used for this task. (5 marks)
b) Declare and initialize all the widgets (views) that you can use for this task. Assume your own ids.
(5 marks)
c) Write the program to calculate the cost of the journey.
Answer:
Explanation: How to calculate fuel economy and usage
Manufacturers give a fuel economy figure for new cars in litres per 100km for urban, extra urban (i.e. higher speeds) and combined (a mixture of the two). This number is determined via a standardised test which, unfortunately, bears very little resemblance to the type of driving the vast majority of people do. If a vehicle you are looking at purchasing has an indicated fuel economy of 8l/100km, everyday driving is probably more likely to be around 10l/100km (this is my experience, after driving and reviewing over 400 cars since 2007).
However, the manufacturer-supplied figures are good for comparing between models, just not calculating what your expected fuel costs will be.

The destination operand of the or instruction cannot be a memory operand.
a. True
b. False
The given statement is false. By performing a bitwise OR operation, the OR instruction supports logical expression.
What is OR instruction?By performing a bitwise OR operation, the OR instruction supports logical expression. If the matched bits from either or both operands are 1, the bitwise OR operator returns 1. If both of the bits are zero, it returns 0. One or more bits may be set using the OR operator. A bitwise instruction is an OR instruction. This implies that the digits of two integers with the same amount of bits (for example, two 32-bit numbers) are handled bit by bit (and not the complete number). If both "input" bits are 0, the OR instruction produces a result of 0, and a result of 1, if at least one input bit is a 1.A memory operand cannot be the destination operand of the OR instruction. The destination operand is always changed by the TEST instruction. The Zero flag is always set when an operand is XORed with 1. The two's complement of an integer can be created by applying the XOR instruction to it.The given statement is false. By performing a bitwise OR operation, the OR instruction supports logical expression.To learn more about OR instruction refer to:
