El jefe de obra en una construcción necesita cercar el terreno donde van a edificar. Sus hombres el primer día cierran los 3/7 del perímetro, el segundo día, los 2/5 de la parte aún pendiente y el tercer día 1/4 de la quedaría todavía. Teniendo en cuenta que tienen que cercar un total de 2 275 metros, (a) ¿Cuántos metros les quedan aún pendientes para concluir su tarea al acabar el segundo día?

(b) ¿Y al acabar el tercer día?

Agraph of a trapezoid can have diagonals with slopes that are negative reciprocals and two pairs of adjacent sides that are congruent, true or false, and why

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
