Acompany has introduced two new products to the market. the revenue generated by product a was $63,000 in the first year, and the revenue increases by 3.5% every year. the revenue generated by product b was $81,000 in the first year, and the revenue increases by 2.1% every year. which function can the company use to determine its total revenue from the two products, r(x), after they have been on the market for x years, and approximately what will be the revenue generated by sales of the products after 6 years? r(x) = 9,000[7(1.035)x + 9(1.021)x]; $635,580 r(x) = 9,000[7(1.035)x + 9(1.021)x]; $169,200 r(x) = 9,000[9(1.035)x + 7(1.021)x]; $170,936 r(x) = 9,000[9(1.035)x + 7(1.021)x]; $688,050

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.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
