I can't see pictures T^T.

To find the are of a triangle, you multiply the dimensions as you would a rectangle, but divide the product by 2.

Example:

The dimensions of triangle B are 4 and 9.

4x9=36

Now divide.

36/2=18

So the area of triangle B is 18.

What kinds of functions can be integrated using partial fraction decomposition? Choose the correct answer below

zaharov [31]

Answer:

B. Rational functions

Step-by-step explanation:

The partial fraction decomposition is used for functions there are described by fractions, and for which the substitution method is not possible. These are rational functions, in which both the numerator and the denominator are polynomials.

So the correct answer is:

B. Rational functions

Write each expression as an algebraic (nontrigonometric) expression in u, u > 0.

max2010maxim [7]

Answer:

$\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0$

Step-by-step explanation:

We want to write the trignometric expression:

$\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)\text{ where } u>0$

As an algebraic equation.

First, we can focus on the inner expression. Let θ equal the expression:

$\displaystyle \theta=\sec^{-1}\left(\frac{u}{10}\right)$

Take the secant of both sides:

$\displaystyle \sec(\theta)=\frac{u}{10}$

Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is:

$\displaystyle o=\sqrt{u^2-10^2}=\sqrt{u^2-100}$

By substitutition:

$\displaystyle= \sin(2\theta)$

Using an double-angle identity:

$=2\sin(\theta)\cos(\theta)$

We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore:

$\displaystyle =2\left(\frac{\sqrt{u^2-100}}{u}\right)\left(\frac{10}{u}\right)$

Simplify. Therefore:

$\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0$

The list that orders the fractions from least to greatest is:

$\frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}$

<h3>Ordering of fractions</h3>

To order the fractions from least to greatest, we have to realize their conversion to decimal.

To realize the conversion, the numerator is divided by the denominator, as ordering decimal numbers are easier than fractions.

Hence, the fractions converted to decimal are:

$\frac{2}{3} = 0.6667$ .

$\frac{7}{12} = 0.5833$ .

$\frac{17}{24} = 0.7083$

$\frac{3}{4} = 0.75$

Hence, the list from least to greatest is, according to the results of the conversions:

$\frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}$
