Write a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below.
For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer.
hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.
The time it takes for a cloud 106,000 AU in radius
to collapse in "free-tall to form a new star is half
the time it would take for an object to orbit the star
on an extremely elliptical orbit with a semimajor
axis of 53,000 AU (half the 106.000 AU radius).
Part A
Use Kepler's third law to find the collapse time, assuming the star has the same mass as the Sun.
Express your answer in years to two significant figures.
