Short answer📘 N.VM.A.3🧠 DOK 1

Question:

A car is traveling north at a speed of 30 miles per hour. Another car is traveling east at a speed of 40 miles per hour. Assuming these are vector quantities, calculate the magnitude of the resultant velocity of the two cars.

✅ Answer:
The magnitude of the resultant velocity is 50 miles per hour.

💡 Explanation:

  • To find the magnitude of the resultant vector when two vectors are perpendicular, use the Pythagorean theorem: (302+402)=(900+1600)=2500=50\sqrt{(30^2 + 40^2)} = \sqrt{(900 + 1600)} = \sqrt{2500} = 50.

  • Thus, the magnitude of the resultant velocity is 50 miles per hour.

Question:

Identify a real-world situation where one quantity changes at a constant rate per unit interval relative to another quantity.

✅ Answer:
An example of a real-world situation where one quantity changes at a constant rate per unit interval relative to another is the speed of a car moving at a constant velocity. Here, the distance traveled changes at a constant rate per unit of time.

💡 Explanation:

  • When a car travels at a constant speed, the distance it covers increases by the same amount for each unit of time, illustrating a constant rate of change.

Question:

Evaluate the following expression correctly by using the order of operations, including parentheses and brackets: 8 + [3 × (6 – 4)² + 5] – 9 What is the value of the expression?

Answer Choices:

  • A) 18
  • B) 20
  • C) 24
  • D) 26
✅ Answer:
24

💡 Explanation:

  • To evaluate the expression 8 + [3 × (6 – 4)² + 5] – 9, follow the order of operations: 1.

  • Inside the parentheses: (6 – 4) = 2 2.

  • Next, evaluate the power: 2² = 4 3.

  • Then, inside the brackets, perform the multiplication: 3 × 4 = 12 4.

  • Add the result to 5 inside the brackets: 12 + 5 = 17 5.

  • Add 8 to the result from the brackets: 8 + 17 = 25 6.

  • Finally, subtract 9: 25 - 9 = 16 Therefore, the value of the expression is 16.

The evening sky was a canvas of colors—orange, pink, and purple. As the sun set, the world seemed to pause; everything was calm, serene. Birds chirped in the distance, their songs echoing across the landscape. It was a moment of reflection, a time to ponder the day's events, and consider the possibilities of tomorrow.

Question:

How does the use of punctuation in the phrase 'The evening sky was a canvas of colors—orange, pink, and purple' contribute to the meaning of the sentence?

Answer Choices:

  • A) It shows a contrast between the colors and the sky.
  • B) It indicates a pause to emphasize the vividness of the colors.
  • C) It suggests the colors are unrelated to the sky.
  • D) It implies that the colors are less important than the sky.
✅ Answer:
It indicates a pause to emphasize the vividness of the colors.

💡 Explanation:

  • The dash is used to create a pause that highlights the vividness and variety of the colors, drawing the reader's attention to the description and enhancing the imagery.

Question:

Explain how increases in human population and per-capita consumption of natural resources can impact Earth's systems. Provide specific examples to support your argument.

✅ Answer:
Increases in human population lead to greater demand for resources such as water, land, and energy, which can result in overexploitation of these resources. For example, deforestation occurs when forests are cleared to make way for agricultural lands or urban development, impacting the carbon cycle and leading to increased greenhouse gases in the atmosphere. Additionally, higher per-capita consumption means more waste and pollution, such as plastic waste polluting oceans and harming marine life.

💡 Explanation:

  • As human populations grow, the demand for natural resources like water, land, and energy increases, leading to potential overuse and depletion.
  • For instance, deforestation for agriculture or development affects the carbon cycle, increasing atmospheric carbon dioxide levels and contributing to climate change.
  • Increased per-capita consumption results in more waste, such as plastics, which can pollute ecosystems and harm wildlife.
  • These examples illustrate how human activity can significantly alter Earth's systems.

Question:

Which of the following statements correctly describe the application of the Law of Sines or the Law of Cosines in solving triangles? Select all that apply.

Answer Choices:

  • A) The Law of Sines can be used to find the length of a side in a right triangle when two angles and one side are known.
  • B) The Law of Cosines can be used to find the length of a side in a non-right triangle when two sides and the included angle are known.
  • C) The Law of Sines is only applicable to right triangles.
  • D) The Law of Cosines applies only to isosceles triangles.
  • E) The Law of Sines can be used to find an unknown angle in a non-right triangle when two sides and one angle are known.
✅ Answer:
The Law of Sines can be used to find the length of a side in a right triangle when two angles and one side are known.;The Law of Cosines can be used to find the length of a side in a non-right triangle when two sides and the included angle are known.;The Law of Sines can be used to find an unknown angle in a non-right triangle when two sides and one angle are known.

💡 Explanation:

  • The Law of Sines is applicable for any triangle, not just right triangles, and can be used when we know two angles and one side or two sides and one angle.

  • The Law of Cosines, on the other hand, is useful for finding unknown sides or angles in any triangle, not just isosceles triangles, particularly when two sides and the included angle are known.

Question:

Two skateboarders, Alex and Jamie, are on a smooth, level surface. Alex pushes against Jamie, causing both of them to move in opposite directions. Which of the following statements correctly apply Newton's Third Law to describe the motion of Alex and Jamie? Select all that apply.

Answer Choices:

  • A) A. Alex exerts a force on Jamie, and Jamie exerts an equal and opposite force on Alex.
  • B) B. The forces exerted by Alex and Jamie are unequal because Alex is stronger.
  • C) C. Both skateboarders move in the same direction after the push.
  • D) D. The force exerted by Alex on Jamie is equal in magnitude and opposite in direction to the force exerted by Jamie on Alex.
  • E) E. Neither skateboarder exerts any force on the other.
✅ Answer:
A, D

💡 Explanation:

  • According to Newton's Third Law, for every action, there is an equal and opposite reaction.
  • When Alex pushes on Jamie, Jamie pushes back with an equal and opposite force.
  • This causes them to move in opposite directions, demonstrating the law of action and reaction.
