5 0

Answer:

  20ln(3)

Step-by-step explanation:

Put 15 for A and solve for t.

  15 = 45e^(-.05t)

  15/45 = 1/3 = e^(-.05t) . . . . divide by 45

  ln(1/3) = -.05t . . . . . . . . . . . take natural logs

  20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify

It will take 20·ln(3) years for the area to decrease to 15 km^2.

mr_godi [17]

14 volunteers will not be able to help.

Step-by-step explanation:

According to given statement;

One booth requires 3 Volunteers.

No. of booths = 16

Given number of volunteers = 62

We will multiply total number of booths with 3 to find the number of volunteers required.

Volunteers required = No. of booths x 3

Volunteers required = 16*3\\

Volunteers required = 48
