Answer:

You will need to convert to degrees when you are taking a right-triangle approach to trigonometry. In other words, if you are not utilizing aspects of the unit circle, you should convert to degrees. The opposite would go for radians. When you are taking a unit circle approach, convert degrees to radians.

The polynomial x^2+3x-1 is a factor of x^4+3x^3-2x^2-3x+1 true or false?

pashok25 [27]

Answer:

Yes, it is true that $x^2+3x-1$ is a factor of $x^4+3x^3-2x^2-3x+1$ .

Step-by-step explanation:

Let us try to factorize $x^4+3x^3-2x^2-3x+1$

$x^4+3x^3-2x^2-3x+1\\\Rightarrow x^4-2x^2+1-3x+3x^3$

Let us try to make a whole square of the given terms:

$\Rightarrow (x^2)^2-2\times x^2 \times 1+1^2+3x^3-3x\\\Rightarrow (x^2-1)^2+3x^3-3x\\$

--------------

Formula used above:

$a^{2} -2 \times a \times b +b^{2} = (a-b)^2$

In the above equation, we had $a = x, b = 1$ .

--------------

Further solving the above equation, taking $3x$ common out of $3x^3-3x$

$\Rightarrow (x^2-1)^2+3x(x^2-1)\\$

Taking $(x^{2} -1)$ common out of the above term:

$\Rightarrow (x^2-1)((x^2-1)+3x)\\\Rightarrow (x^2-1)(x^2+3x-1)$

So, the two factors are $(x^2-1)\ and\ (x^2+3x-1)$ .

$\therefore$ The statement that $x^2+3x-1$ is a factor of $x^4+3x^3-2x^2-3x+1$ is <em>True.</em>

Bennett is setting up a light display for a wedding with two 10-foot strands of lights. The lights will be attached to the top o

Anuta_ua [19.1K]

Answer:

7.1

Step-by-step explanation:

write pythagorean theorem $x^{2}$ + $x^{2}$ = $10^2$

2 $x^2$ = 100

divide 2 both side:

$x^{2}$ = 50

$\sqrt{x^2}$ = $\sqrt{50}$

$x$ = $\sqrt{50}$

$x$ = 7.07106781

round to nearest tenth:

$x$ = 7.1

If f(x) = 4(3x - 5), find f^-1(x)

Sloan [31]

Answer:

The answer is A.

Step-by-step explanation:

Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.

$y=12x-20\\ y+20=12x\\ x=\frac{y+20}{12}$

Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).

f-1(x) = (x+20)/12
