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 }
No, a line of symmetry should cut the shape or object in half and represent a perfect mirror image.
Since we know that the ratio of the model car to the real
car is 1:64, therefore we use this to solve this true length of the real NASCAR
vehicle, let us call this us X, so that:
1 : 64 = 3 inches : X
1 / 64 = 3 inches / X
X = 192 inches

The true length is 192 inches</span>
