By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Dup= 72 miles
<span>ddown= 120 miles </span>
<span>v= riverspeed </span>
<span>rup= 32mph - v </span>
<span>rdown= 32mph + v </span>
<span>t both ways= t </span>
<span>d=r*t </span>
<span>d/r=t </span>
<span>t=ddown/rdown </span>
<span>t=dup/rup </span>
<span>dup/rup = ddown/rdown </span>
<span>(72)/(32-v)=(120)/(32+v) </span>
<span>3840-120v=2304+72v </span>
<span>1536=192v </span>
<span>v=8</span>

Answer:
Step-by-step explanation:
Given is the piecewise function.
The first part is increasing function y = x + 6, when x ≤ -3
The second part is decreasing function y = -x when x > -3
The above is reflection in the first graph (top one)
