Answer:

56.3 in²

Step-by-step explanation:

Given 2 similar figures with linear ratio = a : b, then

area ratio = a² : b²

Here linear ratio = 4 : 3, thus

area ratio = 4² : 3² = 16 : 9

Let x be the surface area of the smaller can then by proportion

\frac{16}{100} = \frac{9}{x} ( cross- multiply )

16x = 900 ( divide both sides by 16 )

x ≈ 56.3 in² ( to the nearest tenth )

In 2012 your car was worth $10,000. In 2014 your car was worth $8,800. Suppose the value of your car decreased at a constant rat
Sonbull [250]

Answer:

g(t) = 10000(0.938)^t

Step-by-step explanation:

Given data:

car worth is $10,000 in 2012

car worth is $8000 in 2014

let linear function is given as

P(t) = at + b

which denote the value of car in year t

take t =0 for year 2012

at t =0, 10,000 = 0 + b

we get b = 10,000

take t =2 for year 2014

at t =2, P(2) = 2a + b

8800 = 2a + 10,000

a = - 600

Thus the price of car at year t after 2012 is given as p(t) = -600t + 10000

let the exponential function p(t)  =ab^2 where t denote t = 0 at 2012

putting t = 0 P(0) = 10,000 we get 10,000 = ab^0

a = 10,000

putting t = 2 p = 8800

8800 =ab^2

b^2 = \frac{8800}{10000}

b = 0.938

g(t) = 10000(0.938)^t
