Revolt · Accepted Answer

C: theta  has a  60 -degree reference angle and is located in Quadrant II or IV

Question 5

What is the range of y is equal to negative 3 sine x minus 4 ?

Revolt · Accepted Answer

C: all real numbers  negative 5 is less than or equal to y comma y is less than or equal to 3

Question 6

The height, h , in feet of a ball suspended from a spring as a function of time, t , in seconds can be modeled by the equation h is equal to 3 sine open paren pi over 2 times open paren t plus 2 close paren close paren plus 5 Which of the following is the graph of this equation?

Revolt · Accepted Answer

D: Image with description A first-quadrant coordinate plane. The horizontal axis goes from 0 to 10 and is labeled Time, in seconds. The vertical axis goes from 0 to 10 and is labeled Height, in inches. Points start at (0 comma 4 point 5) and fall to (1 comma 2). The points rise to (3 comma 8), and rise back to (5 comma 2). The points rise to (7 comma 8), and fall to (9 comma 2). Then the points go up.

Question 7

Which is the graph of y is equal to cosine of x plus 3 ?

Revolt · Accepted Answer

C: Image with description A coordinate plane. The graph starts and rises to (0 comma 4). It starts to fall through (pi over 2 comma 3) to (pi comma 2). It then rises through (3 pi over 2 comma 3) to (2 pi comma 4).

Question 8
