Eric made two investments: •investment q has a value of $500 at the end of the year and increases by $45 per year. •investment r has a value of $400 at the end of the year and increases by 10% per year. what is the first year in which eric sees that investment r’s value exceeded investment q’s value?

10

Step-by-step explanation:

Notice that investment Q’s value grows linearly while investment R’s value grows exponentially. In conclusion, investment R’s value will first exceed investment Q’s value in year number 10

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

- 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
