Shawn's solution is marked incorrect. Which best explains Shawn's error?

A. Shawn added 4 to both sides of the equation
instead of subtracting 4.

B. Shawn multiplied by -5 on both sides of the
equation instead of multiplying by - 1/5

C. Shawn multiplied by -5 on both sides of the
equation instead of dividing by - 1/5

D. Shawn subtracted 3/5 x on the left side of the
equation instead of adding 3/5 x.

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.

3=log(n)=2

answer a: product property

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
