In a lab experiment, a population of 500 bacteria is able to triple every hour. Which equation matches the number of bacteria in the population after 4 hours?

B=500(1+3)^(4)

B=3(500)^(4)

B=3(1+500)^(4)

B=500(3)(3)(3)(3)

Q. In a lab experiment, a population of 500500 bacteria is able to triple every hour. Which equation matches the number of bacteria in the population after 44 hours?\newlineB=500(1+3)4 B=500(1+3)^{4} \newlineB=3(500)4 B=3(500)^{4} \newlineB=3(1+500)4 B=3(1+500)^{4} \newlineB=500(3)(3)(3)(3) B=500(3)(3)(3)(3)
  1. Understand the problem: Understand the problem.\newlineWe are given an initial population of bacteria, which is 500500. We are told that this population triples every hour. We need to find the equation that represents the number of bacteria after 44 hours.
  2. Determine the growth pattern: Determine the growth pattern.\newlineSince the population triples every hour, the growth pattern is exponential. The number of bacteria after each hour can be found by multiplying the previous hour's population by 33.
  3. Write the equation: Write the equation for the exponential growth.\newlineThe general formula for exponential growth is P(t)=P0×rtP(t) = P_0 \times r^t, where P(t)P(t) is the population at time tt, P0P_0 is the initial population, rr is the growth rate, and tt is the time in hours. In this case, P0P_0 is 500500, rr is 33 (since the population triples), and tt is P(t)P(t)11 hours.
  4. Plug in values: Plug in the values into the exponential growth formula.\newlineUsing the formula from Step 33, we get P(4)=500×34P(4) = 500 \times 3^4. This represents the population after 44 hours.
  5. Simplify the equation: Simplify the equation.\newlineThe equation simplifies to B=500×34B = 500 \times 3^4, which is the same as B=500×(3×3×3×3)B = 500 \times (3 \times 3 \times 3 \times 3).
