Answer:
Its perpendicular
Step-by-step explanation:
You can solve the equation to get x=-2.5 and y = -7.5 so they intersect there, but they intersect at 90 degrees so its perpendicular.

20 hours × $72/hour = $1440
Answer:
The required dimension is 1.59 ft
Step-by-step explanation:
Volume of the box is V=XxHxW
Where
X = Length
H = height
W = width
Assume the box is cube. So, X=H=W=Y
V=Y3
Substituting the value of volume
4 = Y3
Taking cube root on both sides
(4)^(1/3) = Y^(3/3)
1.59 = Y
So the required dimensions are
X = H = W = 1.59 ft
As far as I can tell you are correct. The correct answer for x should be
-pi/3
If you plug x=+pi/3 into the expression cos(x/2 + pi/6), it ends i equaling 1/2, not 0.
