What is the average rate of change of the function f(x)=20 ( 1 4 ) x f(x)=20(14)x from x = 1 to x = 2?

jok3333 [9.3K]

Answer: The average rate of change is 3640.

Explanation:

The given function is,

$f(x)=20(14)^x$

The value of f(x) at x=1.

$f(1)=20(14)^(1)$

$f(1)=20\times 14$

$f(1)=280$

The value of f(x) at x=2.

$f(2)=20(14)^(2)$

$f(2)=20\times 196$

$f(2)=3920$

The average rate of change of a function from x₁ to x₂ is,

$\text{Rate of change}=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

$\text{Rate of change}=\frac{f(2)-f(1)}{2-1}$

$\text{Rate of change}=\frac{3920-280}{1}$

$\text{Rate of change}=3640$

Therefore the average rate of change is 3640.

An observer (O) is located 500 feet from a school (S). The observer notices a bird (B) flying at a 39° angle of elevation from h

Serhud [2]

Answer:

h=404.89

Step-by-step explanation:

We are looking for side h, which is opposite of the observer. We know that the side adjacent to the observer is 500 feet. We also know that the angle from the observer to the bird is 39°. Because we have these values, SOH CAH TOA tells us that we should use tangent, opposite over adjacent.

We can set up our equation as follows:

tan(39°)=h/500

We can then solve for h:

500*tan(39°)=h

h=404.89
