There are 498 coins in a bottle 1/3 of the coins are in pounds 124 of the coins are 50p and the rest are 20p work out the total value of 498 coins

(98 points) i need with 5 questions. answer definitions are welcomed, but not necessary.

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

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.
