nomework: Homework 1.1 and 1.2 Score: 0.4 of 1 pt 4 11 of 14 (10 complete) HW Score: 67.14%, 9.4 of 14 & Phys Sci 1.1.73 Question Help The given table lists the distances (in megaparsecs where 1 megaparsec 3.1x 10 km) and velocities (in kilometers per second) of four space objects moving rapidly away from Earth. Complete parts a through d ject Distance Velocity 200 280 530 1500 16,000 25,000 40,000 600 600 Do the points lie in an approximately linear pattern Yes No b. Wrte a linear equation y mx to model this data, using the ordered pair (530,40000), y-75.5x (Simplify your answer. Round to the nearest tenth as needed.) c. An object has a velocity of 60,000 km per sec. Use the equation in part b to approximate how far away it is from Earth The object is approximately 795 megaparsecs away from Earth (Simplify your answer. Round to the nearest integer as needed) 95x10 Approximate A using the value of m d. The value of m in the equation is called the Hubble constant The Hubble constant can be used to estimate the age of the universe, A in years) using the formula A from part b. The age of the universe is about ?bilion years. (Simplify your answer. Round to the nearest tenth as needed.) Enter your answer in the answer box and then click Check AnswerExplanation / Answer
Hey dear your approach is absolutely correct but in part (d) you are asked to write the answer to nearest tenth , so you must need to round off your to 1 decimal place.
So, the correct answer will be 1.3 billion year..
Hope this will help you...have a nice day... :)
