Answer 1

To find the number of infected passengers after one week (7 days), we can substitute $t=7$ into the equation $A(t)=3e^{0.35t}$.

Calculating:

$$A(7)=3e^{0.35\cdot 7}$$

First, calculate $0.35\cdot 7$:

$$0.35\cdot 7=2.45$$

Now compute $e^{2.45}$:

Using a calculator, we find:

$$e^{2.45}\approx 11.605$$

Now, substitute this value back into the equation:

$$A(7)=3\cdot 11.605\approx 34.815$$

Rounding to the nearest whole number:

$$A(7)\approx 35$$

Therefore, after one week, the number of infected passengers is approximately 35 passengers.
