A certain species of fish is to be introduced into a lake, and wildlife experts estimate the population will grow to P(t)=(723)4t4
, where t represents the number of years from the time of introduction.

Answer:

1 year

Step-by-step explanation:

To find the quadrupling time for the population of fish, we need to determine the time it takes for the population to increase by a factor of 4.

Let P₀ = 723 be the initial population at t=0. Then, the population at any time t is given by:

P(t) = P₀(4^t)

If the population quadruples, it means that the new population is four times the initial population:

4P₀ = P₀(4^t)

Dividing both sides by P₀, we get:

4 = 4^t

Taking the logarithm of both sides, we have:

t*log(4) = log(4)

Solving for t, we get:

t = log(4)/log(4) = 1

Therefore, the quadrupling time for this population of fish is 1 year.

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
