Complete the sentence below. A function f is​ _____ on an open interval I​ if, for any choice of x1 and x2 in​ I, with x1less th
mojhsa [17]

Answer:

Increasing if f' >0 and decreasing if f'<0

Step-by-step explanation:

Difference quotient got by getting

\frac{f(x+h)-f(x)}{h} will be greater than 0 if function is increasing otherwise negative

Here h is a small positive value.

In other words, we find that whenever first derivative of a function f(x) is positive the function is increasing.

Here given that for x1, x2 where x1<x2, we have

if f(x1) <f(x2) then the function is decreasing.

Or if x1<x2 and if f(x1) >f(x2) for all x1, and x2 in I the open interval we say f(x) is decreasing in I.

Question is below in picture.
Maurinko [17]

Answer:

<u><em>C. </em></u>\sqrt{89}<u><em> cm</em></u>

Step-by-step explanation:

<u><em>First, we can start out by stating that this is a </em></u><u><em>right triangle</em></u><u><em>, since </em></u><u><em>it has a right angle</em></u><u><em>, shown by the marker square in the corner of the triangle. </em></u><u><em>The x part, is called the hypotenuse</em></u><u><em>. When finding the value of the hypotenuse, we use a thing called the </em></u><u><em>Pythagorean Theorem.</em></u><u><em> This theorem is :</em></u>

<u><em>a^2 + b^2 = c^2</em></u>

<u><em>a is one side length, and b is the other. c is the hypotenuse.</em></u><u><em> To find x, the hypotenuse, we simply </em></u><u><em>plug in the values, and solve.</em></u>

<u><em>8^2 + 5^2 = c^2</em></u>

<u><em>64 + 25 = c^2</em></u>

<u><em>89 = c^2</em></u>

<u><em>To get c alone, we do the </em></u><u><em>square root of 89.</em></u>

<u><em></em></u>\sqrt{89}<u><em> = c</em></u>

<u><em>9.43398113 = c</em></u>

<u><em>So, the answer is </em></u><u><em>C. </em></u>\sqrt{89}<u><em> cm</em></u>
