Find t given that these vectors are perpendicular

Did you get there answer to 44?

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.

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution

The answer is d, none of above hope i
