the value of bb
the only missing bit that you need to find the answer is the value of bb. then, just take away 18% of that to get your answer.
linearly: 8560 bacteria
exponentially: approximately 75233 bacteria
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.
∠q = 62
set < q equal to < s and solve. once you find x plug it back into the equation given for < q.
step-by-step explanation: divide 275 by 5 and you get 55. so he drove 55 miles every hour. now divide 495 by 55 and you get 9.
