Answer:

Step-by-step explanation:

There is a 1/4 chance of landing on an x. If you multiply 4*3 you get 12 (The total amount of parts) but since you multiplied 4 by 3 you also have to multiply 1 by 3, so that would give you 3/12 meaning that 3 parts are labeled "x"

F(x)=sqrt x+2; g(x)=sqrt 8x-6. FInd f(g(x))

zhenek [66]

Hello!

This question is an example of composition of functions. It is using range values of some given function as domain values of some other given function to find new range values. Remember that the domain of the composite function will be the same as the domain of the first function.

Given f(g(x)), for f = $\sqrt{x+2}$ , substitute x with g(x) = $\sqrt{8x-6}$ .

Therefore, $f(g(x))= \sqrt{\sqrt{8x-6} +2}$ .

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
