the equation y=2(3^t) shows the number of infected people from an outbreak of the norovirus. the variable y represents the number of infected people and t represents time in weeks.

in how many weeks will the number if infected people reach 1458?

Respuesta :

Answer:

Step-by-step explanation:

We have the equation

[tex] 2(3^t) = 1458[/tex]

Dividing by 2 on both sides we get

[tex] 3^t = 729[/tex]

Taking the natural logarithm on both sides we get

[tex] t \ln(3) = \ln(729)[/tex]

So t = \frac{\ln(729)}{\ln(3)} = 6.

So at 6 weeks we get 1458 infected people.
