Mo bought a new car from a showroom. The value, $P, of Mo's car is modelled by
P(t)= 20000(0.9)^(kt)+ 1000, where t is the
number of years since Mo bought the car.
a.) Find the price that Mo paid for the car
After three years, the car was valued at
$16 000.
b.) Find k.
Mo will sell his car when it is worth $5000.
c.) Determine the number of years, after
buying the car, that Mo sells it.

452,489 to the nearest thousand is 452,000

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
