Question 1

What is scientific notation used for?

Accepted Answer

Expressing very large or very small numbers in a compact form

Answer

Scientific notation expresses numbers as a product of a coefficient (between 1 and 10) and a power of 10, simplifying calculations with extreme values.

Question 2

What is the slope of a line in a graph?

Accepted Answer

The rate of change, calculated as rise over run (Δy/Δx)

Answer

Slope measures the steepness and direction of a line, calculated as the change in y divided by the change in x between any two points.

Question 3

What is the formula for calculating the area of a circle?

Accepted Answer

A = πr²

Answer

The area of a circle is found by multiplying pi (approximately 3.14159) by the square of the radius.

Question 4

What does a logarithm represent?

Accepted Answer

The exponent to which a base must be raised to produce a given number

Answer

A logarithm answers the question: 'To what power must the base be raised to yield this number?' For example, log₁₀(100) = 2.

Question 5

What is the Pythagorean theorem?

Accepted Answer

In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides (a² + b² = c²)

Answer

The Pythagorean theorem states that in a right-angled triangle, a² + b² = c², where c is the hypotenuse (longest side).
