In 2012 your car was worth $10,000. In 2014 your car was worth $8,850. Suppose the value of your car decreased at a constant rat

monitta

Answer:

The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:

$f(t) = 10000(0.9407)^t$

Step-by-step explanation:

Value of the car:

Constant rate of change, so the value of the car in t years after 2012 is given by:

$f(t) = f(0)(1-r)^t$

In which f(0) is the initial value and r is the decay rate, as a decimal.

In 2012 your car was worth $10,000.

This means that $f(0) = 10000$ , thus:

$f(t) = 10000(1-r)^t$

2014 your car was worth $8,850.

2014 - 2012 = 2, so:

$f(2) = 8850$

We use this to find 1 - r.

$f(t) = 10000(1-r)^t$

$8850 = 10000(1-r)^2$

$(1-r)^2 = \frac{8850}{10000}$

$(1-r)^2 = 0.885$

$\sqrt{(1-r)^2} = \sqrt{0.885}$

$1 - r = 0.9407$

Thus

$f(t) = 10000(1-r)^t$

$f(t) = 10000(0.9407)^t$

Billy wanted to write a ratio of the number of apples to the number of peppers in his refrigerator. He wrote 1:3. Did bully writ

Ludmilka [50]

Answer:

Billy is incorrect. The ratio of the number of apples to the number of peppers is 3:1

Step-by-step explanation:

See the attached figure to better understand the problem

Let

x ----> the number of apples

y ----> the number of peppers

we have

$x=3\ apples$

$y=1\ peppers$

The ratio of the number of apples to the number of peppers is equal to

$\frac{x}{y}$

substitute

$\frac{3}{1}$

therefore

Billy is incorrect. The ratio of the number of apples to the number of peppers is 3:1
