The function f(x) = -x2 - 7x + 30 shows the relationship between the vertical distance of a diver from poll's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diver board. what is a zero of f(x) , and what does it represent? a.) x = 10; the diver hits the water 10 feet away horizontally from the boredb.) x =3; the diver hits water 3 feet away horizontally from the boredc.) x=10.; the diver jumps in the pool 10 second peer second d.) x=3; the diver jumps in at 3 feet per second

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
