Find the circumference and area of a circle with a diameter of 10 inches. Leave your answers in terms of pi. A)C = 5π; A = 20π


B)C = 10π; A = 20π


C)C = 10π; A = 25π


D)C = 5π; A = 25π

The correct option is Option D: Line AC and RS are skew lines.

What is the line?

A line is defined as set of points that extends infinitely in either direction. A line is the shortest distance between any two points.

What are skew lines?

Skew lines are two lines that never intersect and are not parallel also. Hence we can say that the two lines can not exist in the same plane.

From the figure it is clear that

Line AC and RS are in different planes and they are also not intersecting each other, hence according to the definition of skew lines, they are skew lines.

Final answer:

The terms that are 'like' are: 2xy, -xy, and xy.

Explanation:

In mathematics, like terms are expressions that have the same variables raised to the same powers. When adding or subtracting like terms, you can combine them by adding or subtracting their coefficients while keeping the variables and exponents unchanged. This simplifies algebraic expressions and equations, making them easier to work with. For example, in the expression "3x + 2y - 5x + 7y," "3x" and "-5x" are like terms because they both have the variable "x" raised to the first power, so they can be combined to simplify the expression as "(-2x) + 2y + 7y."

The terms that are 'like' are: b. 2xy, d. -xy, and f. xy. To be 'like' terms, they must have the same variables raised to the same powers. In this case, all three terms have the variables x and y raised to the power of 1. The coefficients (the numbers multiplied by the variables) can be different. For example, 2xy, -xy, and xy are all 'like' terms because they have the same variables raised to the power of 1.

Final answer:

In mathematics, like terms are terms that have the same variables and powers. In this case, the like terms are '2xy', '-xy', and 'xy' as they have the same variable part 'xy'.

Explanation:

In mathematics, like terms are terms whose variables have the same powers. The coefficients of these terms do not matter. Coefficients are the number part of the terms, while the variable part are the letters.

Looking at the options:

• a. xy^2
• b. 2xy
• c. x^2
• d. -xy
• e. 2x^2y
• f. xy

In these options, b. 2xy, d. -xy, and f. xy are like terms; they all have the same variable part 'xy'. The coefficients are different, but this does not affect their classification as like terms.
