The number forty one to the power of negative start fraction two over five end fraction end power can be written in the form sta
Fantom [35]
From the description we can infer that we have the expression: 41^{- \frac{2}{5} }.
Now, to write our expression as a as a root, we are going to apply the law of exponents: x^{-n}= \frac{1}{x^n} first
41^{- \frac{2}{5} }= \frac{1}{41^{ \frac{2}{5} }}

Next, we are going to apply the law about fractional exponents: x^{ \frac{m}{n}}= \sqrt[n]{x^m}
\frac{1}{41^{ \frac{2}{5} }}= \frac{1}{ \sqrt[5]{41^2} }

We can conclude that the value of B is 2.

In a right triangle, angle C measures 40°. The hypotenuse of the triangle is 10 inches long. What is the approximate length of t
Zepler [3.9K]

Answer:

<em>Approximate length of the side adjacent to ∠C is </em><em>7.66 inches.</em>

Step-by-step explanation:

*The appropriate triangle is attached below.

From the diagram, the right triangle ABC has

  1. Hypotenuse = \overline{AC}=10\ inch
  2. m\angle C=40^{\circ}

The side adjacent to angle C is BC. We can get the length of BC by applying trigonometric operations.

We know that,

\cos \theta =\dfrac{b}{h}

Putting the values,

\Rightarrow \cos 40 =\dfrac{BC}{10}

\Rightarrow BC=\cos 40 \times {10}

\Rightarrow BC=7.66\ in
