The size of the bacteria after 8 hours will be of A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53 squared inches.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53

In which F(0) is the initial value and F is the growth rate.

A bacteria with an initial size of 180in2 grows by 27% every minute.

This means that A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53. So

A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53

A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53

A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53

In which t is measured in minutes,

What will the size of the bacteria be after 8hours

8 hours has 8*60 = 480 minutes, so this is F(480).

A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53

The size of the bacteria after 8 hours will be of A bacteria with an initial size of 180in2 grows, №17886997, 18.05.2022 19:53 squared inches.

The size of the bacteria after 8 hours will be of 1.2 \times 10^{52} squared inches.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

F(t) = F(0)(1+r)^{t}

In which F(0) is the initial value and F is the growth rate.

A bacteria with an initial size of 180in2 grows by 27% every minute.

This means that F(0) = 180, r = 0.27. So

F(t) = F(0)(1+r)^{t}

F(t) = 180(1+0.27)^{t}

F(t) = 180(1.27)^{t}

In which t is measured in minutes,

What will the size of the bacteria be after 8hours

8 hours has 8*60 = 480 minutes, so this is F(480).

F(480) = 180(1.27)^{480} = 1.2 \times 10^{52}

The size of the bacteria after 8 hours will be of 1.2 \times 10^{52} squared inches.

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

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.

Cost before sale tax=$46.00

Cost after including tax=$48.76

Sale tax=$48.76-46.00

=$2.76

we know,

sale tax=((sales tax rate)/100) * cost before sale tax

2.76=((sales tax rate)/100) *46.00

sale tax rate=(2.76*100)/46

                   =276/46

                    =6%

There fore sales tax rate=6%
