Technically only 1...

If you have to use 4 rows there is only one option;
1 1 1 2
1 1 2 1
1 2 1 1
2 1 1 1

Each number represents the total kids in a row.
1st number is row 1 second number is row 2 etc.


If you can use 2 or 3 rows there are some more answers.

The exponential function that models cell duplication in a lab is f(t) = 2^ t+2 where f(t) is the number of cells after time t (
o-na [289]
ANSWER

11.29 \: hours

EXPLANATION

The exponential function that models cell duplication in the lab is given as

f(t) = {2}^{t + 2}

We want to determine the time it will take for the cells to increase to
10,000.

In other words, we want to find the value of
t
when
f(t) = 10,000

This gives us the equation,

10,000 = {2}^{t + 2}

Recall that,

{a}^{m + n} = {a}^{m} \times {a}^{n}

We apply this property to the right hand side to obtain,

10,000 = {2}^{t} \times {2}^{2}

This implies that,

10,000 =4 \times {2}^{t}

We divide both sides by 4 to get,

2500 = {2}^{t}

We take the antilogarithm of both sides to base 10 to get,

t = log_{2}(2500)

This implies that,

t = 11.29 \: hours
to the nearest hundredth.
