According to one cosmological theory, there were equal amounts of the two uranium isotopes 235u and 238u at the creation of the universe in the "big bang." at present there are 137.7 atoms of 238u for each atom of 235u. using the half-lives 4.51×109 years for 238u and 7.10×108 years for 235u, calculate the age of the universe.

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
