CB is equal to 10m you can tell this bye the side DC being 20 m and the angle of DC is half of CB so that means that CB has to be 10 m
Answer:
I dont know but when u got the answer tell me
Answer:
5 ??????????????????????????????????
F(x)= x² + 5, is just a parabola shfited upwards by 5 units, so, is a smooth graph and no abrupt edges, so from 0 to 3, is indeed differentiable and continuous. So Rolle's theorem applies, let's check for "c" by simply setting its variable to 0, bear in mind that, looking for "c" in this context, is really just looking for a critical point, since we're just looking where f'(c) = 0, and is a horizontal tangent line.
