The Winding river is modeled by r(x)= 
As bridges will be built along x-Axis to cross the river.
so,the bridges work as a tangent to river.
r'(x)=
So , r'(x)=0
→
=0
→3x²+6 x+ 2 x+4=0
→3 x(x+2)+2(x+2)=0
→(x+2)(3 x+2)=0
x=-2, x= -2/3
As there are two values of x, from where we can draw tangents or bridges to the river.So there are maximum of two bridges that we need to built.
Answer:
45 inches
Step-by-step explanation:
C = (pi)(diameter).
Assuming that the radius of the pizza in this case is 7 inches, the diameter is twice that, or 14 inches.
Thus, the circumference of the pizza is C = (3.14)(14 inches) = 45 inches
approximately.
