Answer:
- f(1) = 4
- f(n) = f(n - 1) + 4
Step-by-step explanation:
Given the sequence:
The first term is 4 and common difference is 4
<u>Recursive formula:</u>
- f(1) = 4
- f(n) = f(n - 1) + 4
The answer will be neither the bus nor the trains were running today. (D)
Answer : The volume of box B is 
Step-by-step explanation :
Given :
Volume of box A = 512 cubic meter
Let us assumed that the box A and box B are cubes and the dimensions of cube are same i.e, 'a'.
Volume of box A = V = 
As per question,
When dimensions of box A divided by 2 then the volume of box B will be:
Volume of box A = V' = 
As the box B is similar to box A. So, the volume of box B will be:
Volume of box B = V' = 
Therefore, the volume of box B is
Answer:
147.4°
Step-by-step explanation:
Supplementary angles sum to 180° , then
supplementary angle = 180° - 32.6° = 147.4°
Answer:
857.766cm^3
Step-by-step explanation:
Given data
Lenght = 3m
Internal radius r = 3m
External radius R= 10m
Volume of pipe= πr^2h
Volume of metal= External - Internal
Volume= πR^2h-πr^2h
Volume= πh(R^2-r^2)
Volume= 3.142*3(10^2-3^2)
Volume= 3.142*3(100-9)
Volume= 9.426*(91)
Volume= 857.766cm^3
Hence the volume of the metal is 857.766cm^3
