Help HeLp it is A easy question PLEASE HELP There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.

The rate of change increased by about bass per a year.

1.2

Step-by-step explanation:

Since 3,000 bass population grows by 2% each year, multiply 3,000 by 1.02 to find next year's population.  Since we're looking for a rate of change, multiply that new total by 1.02 again.  The two values that you should have gotten are 3,060 (first time), and 3,121.2

But we know that the population started at 3,000.  Now this is why we needed 3 values:

Take the difference between 3,060 and 3,000.  Then take the difference between 3,121.2 and 3,060.  3,060-3,000=60  and 3,121.2-3,060=61.2

Now 60 and 61.2 are the rates of change for those two values.  There is a 1.2 difference between them, meaning that the rates of change increase by 1.2 annually.

- 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

the answer is simply just 6n add the two together as they have an n
