Answer:
rule: f(n) = n³
missing numbers: 125, 216, 343, 512, 729
Step-by-step explanation:
Your familiarity with the cubes of small integers helps you recognize each of these numbers is a cube. Their sequence is the sequence of cubes of increasing natural numbers.
1 = 1·1·1 = 1³
8 = 2·2·2 = 2³
27 = 3·3·3 = 3³
64 = 4·4·4 = 4³
__
The rule is ...
f(n) = n³
The cubes of 5 through 9 will complete the set of numbers ...
1, 8, 27, 64, 125, 216, 343, 512, 729
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.
