Dean is mountain climbing with sandra and has just climbed a 48-foot vertical rock face. sandra is standing 36 feet away from the bottom of the cliff, looking up at dean. how far away are dean and sandra?

Do 48-36=12. So, sandra is 12 feet away from dean. hope this helped, please mark as brainliest answer!!

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.
