A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the

trapecia [35]

1999 price = 11900
it depreciates 13%
$\frac{13}{100} \times 11900 = 1547$
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
$\frac{13}{100} \times 10353 = 1345.89$
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
$\frac{13}{100} \times 9007.11 = 1170.92$
year 2002 cost = 9007.11 - 1170.92 = 7836.19

How does the graph of y = sec(x + 3) – 7 compare with the graph of y = sec(x)?

with that template in mind,

$\bf y=sec(\stackrel{B}{1}x+\frac{C}{3})\stackrel{D}{-7}$

the derived function has a horizontal shift of C/B or +3/1 or +3, namely 3 units to the left.

and has a vertical shift D = -7, of 7 units downwards.
