 Question 143787: For the following function, C computes a value, where if you add millions of dollars to the value, the result is the cost of implementing a city recycling project when x , as a percent (not its decimal equivalent), citizens participate. a) Using this model, approximately what is the cost if 60% of the citizens participate? Using this model, estimate the percentage of participation that can be expected if \$5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent. Click here to see answer by stanbon(57424)

 Question 144808: When I use the formula T^2/R^3 (Kepler's third law). The only variable given in the problem is the variable for R (which is 0.723 Astronomical Units). When I replace the R with that factor. How can I solve the equation. I tried setting it equal to 0 but that is going to make the answer 0. In case you cannot find the problem, I am indicating it here: #108) If the average radius of the orbit of Venus is 0.723 AU, then how many years does it take for Venuis to complete one orbit of the sun? Use the information in Exercise 107 FOR REFERENCE #107)Kepler's third law. According to Kepler's third law of planetary motion, the ration T^2/R^3 has the same value for every planet in our solar system. R is the average radius of the orbit of the planet measured in astronomical units (AU), and T is the number of years it takes for one complete orbit of the sun.
