What is the value of x? round your answer to the nearest tenth if necessary.

right triangle whose two legs measure seven and four, and whose hypotenuse is x

We know that to find the sides of a right triangle we can use the Pythagorean theorem: A^2 + B^2 = C^2.

Plugging in our sides into the equation:
7^2 + 4^2 = x^2
49 + 16 = x^2
65 = x^2
x = 8.06

Rounding x to the nearest tenth, we get x = 8.1

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.
