The height of a square prism is 3n + 1. The volume of the prism is 3n³ + 13n² + 16n + 4. What is the area of the square base of the prism? (Show all steps.)
Answers
If s is the side of the square base, the area of the square base is s^2. The volume of the square base is, V = (s²) (h) s² = V/h s² = 3n³ + 13n² + 16n + 4 / 3n + 1 You can do this division by factoring, synthetic division, or by plain division. Factoring out 3n + 1 from the numerator gives you: s² = (3n + 1)(n² + 4n + 4) / 3n+1 s² = n² + 4n + 4
Therefore, the area of the square base is n² + 4n + 4.
What is the sum of a 58-term arithmetic sequence where the first term is 6 and the last term is 405?11,097 11,508 11,919 12,330
Answers
Given: 58 - term first term : 6 last term : 405
Sum = n * (a+l)/2 Sum = 58 * (6 + 405)/2 Sum = 58 * 411/2 Sum = 58 * 205.5 Sum = 11,919
