Use f(x) = 2 x and f-'(x) = 2x to solve the problems.

Westkost [7]

Answer:

$f(2) = 1$

$f(1) = \frac{1}{2}$

$f^{-1}(2)=4$

Step-by-step explanation:

Consider the provided functions.

$f(x) = \frac{1}{2}x$

$f^{-1}(x)=2x$

Find f(2) as shown.

Substitute x=2 in $f(x) = \frac{1}{2}x$

$f(2) = \frac{1}{2}\times2$

$f(2) = 1$

Find f(1) as shown.

Substitute x=1 in $f(x) = \frac{1}{2}x$

$f(1) = \frac{1}{2}$

Find f'(2) as shown.

Substitute x=2 in $f^{-1}(x)=2x$

$f^{-1}(2)=2(2)$

$f^{-1}(2)=4$

Why is the side opposite the right angle in a right triangle will always be the longest side?

Pani-rosa [81]

The hypotenuses, is what I believe you're referring to.

<span>The other two are at a 90 degree angle to each other. There is no side that is always adjacent, you just say adjacent if the side happens to be right next to an angle you are describing. Same with opposite, it is the one side that doesn't touch the angle you are describing.</span>

The population of Adamsville grew from 6000 to 13000 in 7 years. Assuming uninhibited exponential growth, what is the expected p

IgorLugansk [536]

Answer:

18107.32

Step-by-step explanation:

Set up the exponential function in the form:

$P = P_0(R)^t$

so P is the new population, $P_0$ is the original population, R is the rate of increase in population, and t is the time in years.

You have to use the information given to find the rate that the population is increasing and then use that rate to find the new population after more time passes.

$13000 = 6000(R)^7\\\\\\frac{13000}{6000} = R^7\\\\\sqrt[7]{\frac{13000}{6000} } = R\\\\\\ R = 1.116786872$

Now that you found the rate, you can use the function to find the population after another 3 years.

$P = 13000(1.116786872)^3\\P = 18107.32317\\$

So the population is 18107, rounded to the nearest whole number.
