Answer:

In 2012 , the population will be 15 million

Step-by-step explanation:

We start by setting up an exponential equation that defines the increase

P(t) = I(1 + r)^t

P(t) represents the present population = 15 million

I is the population in 2007 which is 13.8 million

r is 1.6% = 0.016

t is what we want to calculate

15 million = 13.8 million (1 + 0.016)^t

15/13.8 = (1.016)^t

1.09 = (1.016)^t

ln 1.09 = t ln 1.016

t = ln 1.09/ln 1.016

t = 5.429 which is approximately 5

So in 2007 + 5 = 2012, the population will be 15 million

The factor tree for 1,764 is shown.
Rashid [163]

Answer:

42

Step-by-step explanation:

               |--------------1764------------|

               |                                      |

              2                           |-------882-----------|

                                           |                            |

                                          2               |--------441------|

                                                           |                      |

                                                   |------9-----|        |----49---|

                                                   |               |        |             |

                                                  3              3      7            7

From the factor tree we see that

1764 = 2^2 \times 3^3 \times 7^2

Now we need to find the square root of 1764.

\sqrt{1764} = \sqrt{2^2 \times 3^2 \times 7^2} = \sqrt{(2 \times 3 \times 7)^2} = \sqrt{(42)^2} = 42
