Q. Ocean sunfish are well-known for rapidly gaining a lot of weight on a diet based on jellyfish.\newlineThe relationship between the elapsed time, t t , in days, since an ocean sunfish is born, and its mass, M(t) M(t) , in milligrams, is modeled by the following function:\newlineM(t)=(1.34)t6+4 M(t)=(1.34)^{\frac{t}{6}+4} \newlineComplete the following sentence about the daily rate of change in the mass of the sunfish.\newlineRound your answer to two decimal places.\newlineEvery day, the mass of the sunfish is multiplied by a factor of
  1. Identify Function: Identify the function that models the mass of the sunfish.\newlineThe function given is M(t)=(1.34)(t6)+4M(t) = (1.34)^{(\frac{t}{6})+4}. This function represents the mass of the sunfish as a function of time in days.
  2. Determine Rate of Change: Determine the daily rate of change.\newlineThe daily rate of change is the factor by which the mass changes when tt increases by 11 day. To find this, we need to calculate M(t+1)M(t+1) and divide it by M(t)M(t).
  3. Calculate M(t+1)M(t+1): Calculate M(t+1)M(t+1).M(t+1)=(1.34)((t+1)6+4)M(t+1) = (1.34)^{\left(\frac{(t+1)}{6}+4\right)}
  4. Simplify M(t+1)M(t+1): Simplify M(t+1)M(t+1).
    M(t+1)=(1.34)(t6+16+4)M(t+1) = (1.34)^{\left(\frac{t}{6}+\frac{1}{6}+4\right)}
    M(t+1)=(1.34)(t6+4)×(1.34)16M(t+1) = (1.34)^{\left(\frac{t}{6}+4\right)} \times (1.34)^{\frac{1}{6}}
  5. Calculate Rate of Change: Calculate the daily rate of change.\newlineThe daily rate of change is M(t+1)/M(t)=(1.34)(t/6)+4×(1.34)1/6/(1.34)(t/6)+4M(t+1)/M(t) = (1.34)^{(t/6)+4} \times (1.34)^{1/6} / (1.34)^{(t/6)+4}
  6. Simplify Expression: Simplify the expression for the daily rate of change.\newlineThe terms (1.34)(t6)+4(1.34)^{(\frac{t}{6})+4} cancel out, leaving us with (1.34)16(1.34)^{\frac{1}{6}}.
  7. Calculate Value: Calculate the value of (1.34)16(1.34)^{\frac{1}{6}}. Using a calculator, we find that (1.34)161.048113(1.34)^{\frac{1}{6}} \approx 1.048113.
  8. Round Rate of Change: Round the daily rate of change to two decimal places.\newlineThe daily rate of change, rounded to two decimal places, is approximately 1.051.05.
