Consider the exponential function
evablogger [386]

<u>Given</u>:

The given function f(x)=19,000 \cdot 0.96 ^x which models the value of Mark’s car, where x represents the number of years since he purchased the car.

We need to determine the approximate value of Mark's car after 7 years.

<u>Value of the car:</u>

The value of the car after 7 years can be determined by substituting x = 7 in the function f(x)=19,000 \cdot 0.96 ^x, we get;

f(7)=19,000 \cdot 0.96 ^7

f(7)=19,000 \cdot 0.7514474781

f(7)=14277.502

Rounding off to the nearest dollar, we get;

f(7)=14278

Thus, the approximate value of Mark's car after 7 years is $14278.

Hence, Option a is the correct answer.

Is x% of y is always the same as y% of x​
11Alexandr11 [23.1K]

Answer:

True

Step-by-step explanation:

Firstly, “ % ” means percent, which, as it name says, is the amount of the number per 100 .

Take 5% for instance, 5 percent would mean 5/100

Likewise, x%=x/100

Now x% of y means x/100×y=xy/100

but also, y% of x means y/100×x=yx/100

and therefore these two are the same!
