Charlie determined that the distance from her grandmother's house to her house is more than 20,000 feet but less than 26,000 feet. which of the following could be a reasonable estimate for the distance between the houses? a. 2.1 x 10^4 ft b. 2.1 x 10^3 ft c. 2.5 x 10^-4 ft d. 2.1 x 10^-4 ft e. 2.1 x 10^3 ft f. 2.5 x 10^4 ft (chose all that apply)

2.1 x 10^4 = 21000, and that fits the range of the boundaries

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
