On the interval [0, 21), which points are intersections of r = 5 + 4 sin(O) and r = -6 sin(O)? Check all that apply. 0-71

there is no

it would be 6xy and -16xy.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
