Add. PLEASE HELPP
(X^2 + 1 - 4x^3 + 3x^4) + (-x^2 - 2x^4 + x^3 + 4).
Express the answer in standard form. Enter your answer in the box.

- 3x³ + 5

Step-by-step explanation:

Remove the parenthesis from the 2 expressions, that is

x² + 1 - 4x³ + 3 - x² - 2 + x³ + 4

Collect like terms, largest exponents to smallest, that is

(3 - 2) + (- 4x³ + x³) + (x² - x²) + 1 + 4

= - 3x³ + 5 ← in standard form

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.

idk this answer sorry cant on this one.
