WITCHER [35]

Answer:

26x³ - 12x² + 5x + 7

Step-by-step explanation:

  1. (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
  2. 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
  3. 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
  4. 26x³ + 5x + 7 - 12x²

= 26x³ - 12x² + 5x + 7

Write a recursive formula for each sequence given or described below.
valentinak56 [21]

Answer:

a_{n} =a_{n-1} +3000 and a₁ =30000 for n = 2,3,4,5,6, ......

Step-by-step explanation:

Doug has joined a job with a starting salary of $30000 per year.  

Hence, if a₁ is the salary of Doug in the first year, then  

a₁ =30000

Now, each year Doug will receive a raise of $3000 in his salary.

Hence, in the 2nd year, his salary(a₂) will become ( a₁ +3000) per year.

Again, in the 3rd year, his salary(a₃) will become ( a₂ +3000) per year.

Therefor, in the similar manner the recursive formula for his salary in each year will be given as a_{n} =a_{n-1} +3000 and a₁ =30000 for n = 2,3,4,5,6, ...... {aₙ is the yearly salary of Doug in the nth year} (Answer)
