Find the roots of the function f(x) = 3x4 - 48.

Andrew [12]

Answer:

$x=\pm 2\text{ or } x = \pm 2i$

Step-by-step explanation:

We are given:

$0=3x^4-48$

Factor:

$0=3(x^4-16)$

Difference of Two Squares:

$0=3(x^2-4)(x^2+4)$

Zero Product Property:

$(x^2-4)=0\text{ or } x^2+4=0$

Solve:

$x^2=4\text{ or } x^2=-4$

Take the square root. Since we are taking an even-root, it requires plus/minus:

$x=\pm 2\text{ or } x = \pm 2i$

Find the length of the unknown side. Round your answer to the nearest tenth.

Paraphin [41]

Answer:

The correct option is: 11.5

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so using Pythagorean theorem, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

(Rounded to the nearest tenth)

So, the length of the unknown side is 11.5
