Answer:

$AB =10.8166538264$

$AB \approx10.8$

Step-by-step explanation:

$A( - 5,6),B(1, - 3)$

$A( - 5,6),B(1, - 3) \\ A( { x }_{ 1 } , { y }_{ 1 } ),B( { x }_{ 2 } , { y }_{ 2 } )$

$AB = \sqrt{( { { x }_{ 2 } - { x }_{ 1 } ) }^{2} + {( { y }_{ 2 } - { y }_{ 1 } ) }^{2} }$

$AB = \sqrt{ {(1 - - 5)}^{2} + {( - 3 - 6)}^{2} }$

$AB = \sqrt{ {(1 + 5)}^{2} + { (- 3 - 6)}^{2} }$

$AB = \sqrt{ {(6)}^{2}+ {( - 9)}^{2} }$

$AB = \sqrt{36 + 81}$

$AB = \sqrt{117}$

$AB =10.8166538264$

$AB \approx10.8$

In 2010, the average person in Mexico used about 5.25 kilowatt-hours of electricity per day. The population of

liubo4ka [24]

5.82*10^8 Kilowatt-hours of electricity is used on average in Mexico each day.

Step-by-step explanation:

The average electricity will be calculated by multiplying the number of people with the amount of electricity used each day.

Given

Electricity used each day =e = 5.25 kWh

Population of the city = p =1.11*10^8

So,

$Electricity\ used\ each\ day = e*p\\=5.25*1.11*10^8\\=5.82*10^8\ kWh\\$

5.82*10^8 Kilowatt-hours of electricity is used on average in Mexico each day.
