1. Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?

• A. -5
• B. i^5
• C. 5√-1
• D. 1/5i

Correct answer: C

Rationale: Rationale: - The imaginary unit, denoted as "i," is defined as the square root of -1. - Therefore, 5i can be expressed as 5 times the square root of -1, which is equivalent to 5√-1. - Option A, -5, is a real number and not an imaginary unit multiple. - Option B, i^5, is equal to i because i raised to any power that is a multiple of 4 results in 1, and i^5 is equivalent to i. - Option D, 1/5i, is the reciprocal of 5i and not equivalent to 5i.

2. A table top has dimensions of 75cm by 50cm. What is its perimeter if opposite sides are equal?

• A. 125cm
• B. 150cm
• C. 200cm
• D. 50cm

Correct answer: B

Rationale: Rationale: - Given that the table top has dimensions of 75cm by 50cm. - Since opposite sides are equal, the table top can be divided into two pairs of equal sides: 75cm and 50cm. - To find the perimeter, we add up all four sides: 75cm + 50cm + 75cm + 50cm = 250cm. - However, since opposite sides are equal, we only need to consider two sides: 75cm + 50cm = 125cm. - Therefore, the perimeter of the table top is 125cm + 125cm = 150cm. - Hence, the correct answer is B) 150cm.

3. Which of the following is NOT a major division of the nervous system?

• A. Peripheral nervous system
• B. Central nervous system
• C. Somatic nervous system
• D. Autonomic nervous system

Correct answer: C

Rationale: The somatic nervous system is actually a component of the peripheral nervous system, responsible for voluntary control of skeletal muscles and sensory information. The major divisions of the nervous system are the central nervous system (which includes the brain and spinal cord) and the peripheral nervous system (which includes all nerves outside the central nervous system). The autonomic nervous system, on the other hand, is a division of the peripheral nervous system responsible for involuntary functions like heart rate and digestion. Therefore, the correct answer is C, the somatic nervous system, as it is not a major division of the nervous system.

4. Which of the following is a unit of work and energy?

• A. Pascal (Pa)
• B. Kilowatt-hour (kWh)
• C. Coulomb (C)
• D. Tesla (T)

Correct answer: b

Rationale: Kilowatt-hour is a unit used to measure both work and energy, especially in the context of electricity consumption.

5. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."

• A. "My biggest fear"
• B. "that I wouldn't live life to the fullest"
• C. "life"
• D. "the fullest"

Correct answer: B

Rationale: Option B functions as the object of the verb "is," making it a noun clause.

6. Bradycardia refers to a heart rate that is:

• A. Normal (60-100 bpm)
• B. Slightly elevated (100-120 bpm)
• C. Significantly elevated (>120 bpm)
• D. Abnormally slow (<60 bpm)

Correct answer: D

Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.
