Answer:

The fraction of income does Lakshmi donate to charity is $\frac{1}{5}$ .

Step-by-step explanation:

Let us assume that the income of the Lakshmi be x.

As given

Lakshmi donates 20 % of her income to charity .

20% is written in the decimal form.

$= \frac{20}{100}$

= 0.20

Lakshmi donates to charity = 0.20 × x

= 0.20x

$Fraction\ of\ Lakshmi\ income\ donate\ to\ charity = \frac{Lakshmi\ donates\ to\ charity}{Total\ income\ of\ Lakshmi}$

Putting the values in the above

$Fraction\ of\ Lakshmi\ income\ donate\ to\ charity = \frac{0.20x}{x}$

$Fraction\ of\ Lakshmi\ income\ donate\ to\ charity = \frac{20}{100}$

$Fraction\ of\ Lakshmi\ income\ donate\ to\ charity = \frac{1}{5}$

Therefore the fraction of income does Lakshmi donate to charity is $\frac{1}{5}$ .

Find g^-1(x) <br><br> A<br> B<br> C<br> D

Katyanochek1 [597]

<h2>Answer:</h2>

$a. \ g^{-1}=-1 \pm\sqrt{\frac{3}{x}+1}$

<h2>Step-by-step explanation:</h2>

A function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function $f$ has an inverse function if and only if there is no any horizontal line that intersects the graph of $f$ at more than one point. So the function is called one-to-one. The graph of $g$ is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find $g^-{1}(x)$ :

$g(x)=\frac{3}{x^2+2x} \\ \\ Substitute \ g(x) \ by \ y \\ \\y=\frac{3}{x^2+2x} \\ \\ Interchange \ x \ and \ y: \\ \\ x=\frac{3}{y^2+2y} \\ \\ Solve \ for \ y: \\ \\y^2+2y=\frac{3}{x} \\ \\ Completing \ square \\ \\y^2+2y\mathbf{+ 1}\mathbf{-1}=\frac{3}{x} \\ \\(y+1)^2=\frac{3}{x}+1 \\ \\y+1=\pm\sqrt{\frac{3}{x}+1} \\ \\ y=-1 \pm\sqrt{\frac{3}{x}+1}$

Finally, substitute $y \ by \ g^{-1}$ :

$boxed{g^{-1}=-1 \pm\sqrt{\frac{3}{x}+1}}$

Find the angle between u = (-2,-5) and v = (5,2)

OleMash [197]

The angle between u = (-2,-5) and v = (5,2) is 134 degrees approximately.

<u>Solution:</u>

Given, two vectors are u = (-2, -5) and v = (5, 2)

We have to find the angle between two vectors.

We know that,

$a. b=\|a\| .\|b\| \times \cos \theta$

where $\theta$ is angle between vectors a and b

$\text { Now vectors are }(-2 \vec{\imath}-5 \vec{\jmath}) \text { and }(5 \vec{\imath}+2 \vec{\jmath})$

$(-2 \vec{\imath}-5 \vec{\jmath}) \cdot(5 \vec{\imath}+2 \vec{\jmath})=\sqrt{(-2)^{2}+(-5)^{2}} \times \sqrt{5^{2}+2^{2}} \times \cos \theta$

$\text { since }\|a\|=\sqrt{x^{2}+y^{2}} \text { for } a=x \vec{\imath}+y \vec{\jmath}$

$\begin{array}{l}{-10-10=\sqrt{29} \times \sqrt{29} \times \cos \theta} \\\\ {-20=29 \times \cos \theta} \\\\ {\cos \theta=\frac{-20}{29}} \\\\ {\theta=\cos ^{-1} \frac{-20}{29}} \\\\ {\theta=133.60}\end{array}$
