Transforming Formulas Quiz

What is the first step in transforming a formula to solve for a specific variable?

• Multiply both sides by zero

• Identify the variable to solve for

• Add random numbers to both sides

• Ignore the variable

In the formula V^2 = U^2 + 2as, what operation is used to isolate the term 2as?

• Division

• Addition

• Subtraction

• Multiplication

What is the result of solving V^2 = U^2 + 2as for s?

• s = (V^2 + U^2) / 2a

• s = (V^2 / U^2) * 2a

• s = (V^2 - U^2) / 2a

• s = (V^2 * U^2) / 2a

Why is it important to consider restrictions when transforming formulas?

• To change the variable

• To make the formula more complex

• To avoid division by zero

• To ensure the formula is always positive

What is the reciprocal of 1/2 used for in solving P = 1/2n(a + 1)?

• To add to both sides

• To multiply both sides

• To subtract from both sides

• To divide both sides

When solving for n in P = 1/2n(a + 1), why are parentheses important?

• They act as blocks that must be moved as a whole

• They make the equation more complex

• They can be ignored

• They simplify the equation

What is the result of solving P = 1/2n(a + 1) for n?

• n = p / (2a + 1)

• n = 2p * (a + 1)

• n = p * (2a + 1)

• n = 2p / (a + 1)

What is the final step to solve for a in P = 1/2n(a + 1)?

• Add 1 to both sides

• Divide by n

• Subtract 1 from both sides

• Multiply by n

What restriction is applied when solving for a in P = 1/2n(a + 1)?

• a must be zero

• n must not be zero

• a must not be zero

• n must be zero

What happens if a square root contains a negative number?

• It remains the same

• It becomes positive

• It becomes zero

• It becomes a complex number
