Answer:

The values of 'x' are -1.2, 0, 0, $-4i$ or $4i$ .

Step-by-step explanation:

Given:

The equation to solve is given as:

$5x^5+6x^4+80x^3+96x^2=0$

Factoring $x^2$ from all the terms, we get:

$x^2(5x^3+6x^2+80x+96)=0$

Now, rearranging the terms, we get:

$x^2(5x^3+80x+6x^2+96)=0$

Now, factoring $5x$ from the first two terms and 6 from the last two terms, we get:

$x^2(5x(x^2+16)+6(x^2+16))=0\\x^2(x^2+16)(5x+6)=0$

Now, equating each factor to 0 and solving for 'x', we get:

$x^2=0\\x=0\ and\ 0\\\\5x+6=0\\x=\frac{-6}{5}=1.2\\\\x^2+16=0\\x^2=-16\\x=\sqrt{-16}=\pm 4i$

There are 3 real values and 2 imaginary values. The value of 'x' as 0 is repeated twice.

Therefore, the values of 'x' are -1.2, 0, 0, $-4i$ or $4i$ .

In the Diagram Lines M And N are Parallel M < 2 = 150 degress, Find the Measure of the following angles

Snezhnost [94]

<4= 150
<6=150
because the angels are parallel <4 & <2 are the exact same measurements and because 6 is perpendicular to <4 & <2 thus making it also 150 degrees

A Tourist Information Center is between a Bus Station and a Train Station. When mapped on a grid, the Tourist Information Center

deff fn [24]

Given :

The Tourist Information Center is located at (11,0) and the Bus Station is located at (-1,-10).

Also , Tourist Information Center is between a Bus Station and a Train Station.

To Find :

The point of location of train station .

Solution :

Let , point of location of train station is ( x,y ).

We know , mid-point of two points ( a, b) and ( c, d ) is given by :

$(\dfrac{a+c}{2},\dfrac{b+d}{2})$ .

Since , Tourist Information Center is between a Bus Station and a Train Station.

So , it is given by :

$( 11 , 0 ) = (\dfrac{-1+x}{2},\dfrac{-10+y}{2})$

Comparing both coordinate :

$\dfrac{x-1}{2}=11\\\\x=22+1\\\\x=23$

and

$\dfrac{y-10}{2}=0\\\\y=10$

Therefore , Train Station is located at point ( 23 , 10 ) .

Hence , this is the required solution .
