Answer:
$79.20
Step-by-step explanation:
(a) yes it does
(b) the rate is constant because the rate of change (slope) is the same throughout the function.
(c) The rate, or rate of change, is -1/2.
y1 - y2/x1-x2
4 - 2/3 - 9
2/-6
-1/2
0.26
A (x , y), radius of circle = 1
y/radius = y/1 = sin 15°
y = 0.26
