Answer:
a triangle that is rotated about a given point.
Step-by-step explanation:
Answer:
a) C(x) = 15000/x + 6x +80
b) Domain of C(x) { R x>0 }
Step-by-step explanation:
We have:
Enclosed area = 1500 ft² = x*y from which y = 1500 / x (a) where x is perpendicular to the river
Cost = cost of sides of fenced area perpendicular to the river + cost of side parallel to river + cost of 4 post then
Cost = 10*y + 2*3*x + 4*20 and accoding to (a) y = 1500/x
Then
C(x) = 10* ( 1500/x ) + 6*x + 80
C(x) = 15000/x + 6x +80
Domain of C(x) { R x>0 }
As the y-intercept increases, the graph of the line shifts up. B. as the y-intercept decreases, the graph of the line shifts left. ... As the y-intercept decreases, the graph of the line shifts down.
I hope this works for you!
