This graph shows the rate of a scuba diver’s ascent to the surface. What does the y-intercept of the graph represent? Graph of a diagonal line on a coordinate plane going up and to the right with Time (min) on x-axis and Depth (m) on y-axis. When min is 0, m is -30. When min is 3, m is -10

A. The scuba diver ascended at a rate of 10 meters per minute.
B. The scuba diver started her ascent at the surface of the water.
C. The scuba diver ended her ascent 35 meters below the surface of the water.
D. The scuba diver was 35 meters below the surface of the water at the start of the ascent.

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."

In which form is the following function written? y = - 2(x – 3)(x + 5)

Can someone me with these two circle theorem questions asap?
