Answer:
The beam should be placed 8 feet from the center.
Step-by-step explanation:
The struts are y = √(x + 8) and y = √(x − 4). The struts are 2 feet apart at the location of the beam:
√(x + 8) − √(x − 4) = 2
Solving:
√(x + 8) = 2 + √(x − 4)
x + 8 = 4 + 4√(x − 4) + x − 4
8 = 4√(x − 4)
2 = √(x − 4)
x − 4 = 4
x = 8

Answer:
y=(-3/2)x+24
Step-by-step explanation:
a perpendicular line should have the negative reciprocal of the line that it is perpendicular to.
negative reciprocal of 2/3 is -3/2
out line should look something like this
y=(-3/2)x+b
then we use the given point to find b
6=(-3/2)12+b
6=-18+b
b=24
