Answer:
c
Step-by-step explanation:
in upper triangle:
Tan60=p/b
√3=a/6
∴a=6√3
again, sin60=p/h
√3 /2=6√3 /b
∴b=12
now, taking down triangle:
cos45=h/b
1/√2 =12/c
∴c=6√2
Roy: y=150-1.5x
Luis: y=200-2.5x
150-1.5x=200-2.5x
150=200-x
-50=-x
50=x
So in 50 weeks, Roy and Luis will weigh the same at 75 pounds each.
179.36 pounds
(1, 1), (1, 2), (1, 3), (1, 4), (1, 5)
As long as the same x-coordinate appears more than once, the is not a function.
