A small college had 7,500 students enrolled in 2010, and the number of students enrolled has increased by 3% each year since. It f(n) represents the number of students enrolled n years after 2010, then which function best represents its value?

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

true

step-by-step explanation:

452,489 to the nearest thousand is 452,000

i think that you should ask google for the answer to that problem because if we don't know it google does
