One model for car depreciation is as follows, where cis the original cost, vis the value of the car after tyears, and ris the rate
of depreciation
v= (1-1)
if the original cost of the car was $21,000 and the rate of depreciation is 15%, what will be the value of the car after 5 years?
[round to the nearest dollar.]
a. $17,850
b. $3,150
c. $9,318
d. $19,472

0,0

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
