Four people invested in a restaurant. one person invested $100,000. two others invested in the ratio x: 2x, and the fourth person invested an amount equal to the other three investors combined. the total investment was $1,100,000. 1. write an expression for the amount invested by the fourth person? 2. write an equation that allows you to find the amount invested by each person3. how much did each person invest?

The heaviest 16% of all men in weight weigh more than how many pounds ?

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.

Factor the polynomial, if possible. if the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75
