La municipalidad de Miraflores organizó un día de limpieza de las playas de su distrito. A cada una de las cuadrillas de trabajo se le asignó una extensión de playa para cubrir toda la franja litoral del distrito. A la cuadrilla “A” le correspondió 1 500 m, a la cuadrilla “B” 1 260 m, a la cuadrilla “C” 968 m, y a la cuadrilla “D” 1 272 m. ¿Cuál es la longitud total de la franja litoral del distrito? ¿Cuántos metros más limpio la cuadrilla “A” que la cuadrilla “D”? ¿Cuántos metros hay que darle a la cuadrilla “C” para que limpie igual que la cuadrilla “B”?

Given a singly linked list, remove nodes greater than x. Example: List = 100 → 105 + 50 X = 100 List becomes 100 + 50 Return a reference to the root node of the list after removing 105. Function Description Complete the function remove Nodes in the editor below. The function must return a reference to the root node of the final list. removeNodes has the following parameter(s): listHead: a reference to the root node of the singly-linked list x: integer, the maximum value to be included in the returned singly-linked list Constraints • 1 sn, xs 105 • 1 s SinglyLinkedListNode values s 105

a) Give equations of one-sheeted and two-sheeted hyperboloids and draw the pictures of the corresponding surfaces (schematically, no need for specifics). b) Let S be 4e surface given by the equation x^2 ? 6x + y^2 ? z^2 + 2(y ? z) + 9 = 0, Is S a hyperboloid? If yes, what type? If no, what is it? c) Show that the curve (3 + e^t/root 2, e^t/root 2 ? 1, e^-t -1) is normal to the surface S (in part (b)) at the point of intersection.

*7.6 (Algebra: quadratic equations) Design a class named QuadraticEquation for a quadratic equation ax2 + bx + x = 0. The class contains: The private data fields a, b, and c that represent three coefficients A constructor for the arguments for a, b, and c. Three get methods for a, b, and c. A method named getDiscriminant O that returns the discriminant, which is b-4ac. The methods named getRoot 10 and getRoot2 for returning the two roots of the equation using these formulas: 2 – 4ac and 2 24ac 2a These methods are useful only if the discriminant is nonnegative. Let these meth ods return 0 if the discriminant is negative. Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display “The equation has no roots.” See Exercise 4,1 for sample runs
