If the relationship a2 + b2 = c2 applies to triangle abc, angle c is a staright angle. if not the connection, angle c is not a straight angle. in a green area, lines have been drawn up for training plans. show which of the u, v, x and y angles have not managed to get right.

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?
