Aleks04 [339]

Answer:

613297

Step-by-step explanation:

The equation for exponential decay is y=A(1-r)^t

A=654,000

r (rate)=0.008 (0.8% as a decimal)

t=8 (2009-2000=8)

y=659,000(1-0.008)^8

y=613297.4028

Since you can't have part of a person, round: y=613297

A fishing hook is at an elevation of −12 m relative to sea level. Half an hour later, the fishing hook's elevation increases by

yulyashka [42]

Answer:

$-12m + 12m =0$

Step-by-step explanation:

Given

$Initial\ Position = -12m$

$Rise = 12m$

Required

Represent as an equation

The new position of the hook is calculated by:

$New\ Position = Initial\ Position + Rise$

This gives:

$New\ Position = -12m + 12m$

$New\ Position = 0$

Hence, the equation is:

$-12m + 12m =0$
