45. Trayectorias de cometas Algunos cometas, como el cometa Halley, son una parte permanente del sistema solar,
que viajan en órbitas elípticas alrededor del Sol, Otros
pasan
por el sistema solar sólo un vez, siguiendo una trayectoria
hiperbólica con el Sol en un foco. La figura muestra la tra-
yectoria de esta clase de cometa. Encuentre una ecuación
para la trayectoria, suponiendo que lo más que el cometa se
aproxima al Sol son 2 x 10' millas y que la trayectoria que
estaba tomando el cometa antes de acercase al sistema solar
es en un ángulo recto a la trayectoria que continúa después
de dejar el sistema solar.

James was playing a game with his friends. he won 35 points. then he lost 15, lost 40 and won 55. how did he come out

Can some one explain how to slove specifically, what is the value of x? 0.9(x+1.4)-2.3+0.1x=1.6 enter the answer as a decimal in the box. x= ?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
