Answer: Neither linear nor exponential (choice B)

Through interpolation, a graphing calculator, or trial and error, you can find the function to be f(x) = 2x^2. This is a polynomial function. It is not linear as it graphs out a curved parabola. It's not exponential either since the exponent isn't a variable. This also can be considered a power function.

vodka [1.7K]

Answer:

$7,718

Step-by-step explanation:

Given that :

Cost of car in 2007 = $34000

Cost of car in 2014 = $16200

Predicted value of car in 2021

Lets obtain the percentage Depreciation (d) :

Worth (A) of car in 2014 = $16200

Time (t) = 2014 - 2007 = 7 years

Initial cost (I) = price in 2007

A = I(1 - d/100)^7

16200 = 34000( 1 - d/100)^7

16200 = 34000(1 - 0.01d)^7

(16200/34000)^1/7= 1 - 0.01d

0.8995 = 1 - 0.01d

0.01d = 1 - 0.8995

d = 0.1005 /0.01

d = 10.05

Value of car in year 2021:

t = 2021 - 2007 = 14 years

A = I(1 - 10.05/100)^14

A = 34000(1 - 0.1005)^14

A = 34000(0.8995)^14

A = 34000 * 0.2269950

A =7717.83100

Approximate worth = $7718

How do write 3 15/44 as a decimal
Morgarella [4.7K]
Change 3 and 15/44 to an improper fraction: 3 x 44 + 15 = 147 So, 147/44

times the whole number (3) by the bottom number of the fraction (44 or denominator) then added the top number (15 or numerator). Once you get that number you put it over the original denominator in the question (44).

then you divide the two number so...   147/44 = 3.340909091 <- That's your answer!
