Andrea wants to enclose a rectangular field with four internal partitions as shown. If the area of the field must be 13100 square feet, what dimensions will require the least fencing? Note that the internal partitions also require fencing. Q The width should be :] feet and the length should be :] feet. (Round your answers to two decimal places) Consider the function m) = 123:5 + 45:2:4 360m3 + 5. f(:c) has inflection points at (reading from left to right) x = D, E, and F For each of the following intervals, tell whether f(:c) is concave up or concave down. 0)= > Next Question Consider the function m) = 2:133 + 36:02 192m + 5. For this function there are three important open intervals: ( 00, A), (A, B), and (B, 00) where A and B are the critical numbers. For each of the following open intervals, determine whether f(a:) is increasing or decreasing. ( oo,A): (AB): (3,00): Using the First Derivative Test, we can conclude: am = Am) has am = Mac) has ) Next
