Transforming Formulas Quiz

What is the first step in solving a formula for a specific variable?

• Multiply both sides by zero

• Ignore the variable

• Add random numbers to both sides

• Identify the variable to solve for

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

• Addition

• Division

• Subtraction

• Multiplication

What is the final expression for s in the formula V^2 = U^2 + 2as?

• s = (V^2 + U^2) / 2a

• s = (V^2 / U^2) * 2a

• s = (V^2 - U^2) / 2a

• s = (V^2 * U^2) / 2a

What restriction is applied to the formula V^2 = U^2 + 2as?

• a must be different from zero

• U must be zero

• V must be different from zero

• a must be zero

In the formula P = 1/2n(a + 1), what is the reciprocal of 1/2?

• 0

• 1

• 2

• 1/2

What is the expression for n in the formula P = 1/2n(a + 1)?

• n = 2p / (a + 1)

• n = p / (2a + 1)

• n = 2p * (a + 1)

• n = p / 2(a + 1)

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

• n must be different from one

• a must be different from negative one

• a must be zero

• n must be zero

When solving for a in the formula P = 1/2n(a + 1), what is the first step?

• Divide both sides by n

• Add n to both sides

• Multiply both sides by 2

• Subtract 1 from both sides

What is the expression for a in the formula P = 1/2n(a + 1)?

• a = p / 2n + 1

• a = 2p * n + 1

• a = 2p / (n + 1)

• a = 2p / n - 1

What is a common restriction when dealing with square roots in formulas?

• Square roots cannot have negative numbers

• Square roots can have negative numbers

• Square roots must be positive

• Square roots must be zero
