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

PLEASE HELP
shtirl [24]

Answer:

70 m

Step-by-step explanation:

AB makes a 30-60-90 triangle with the wall.

AC makes a 45-45-90 triangle with the wall.

In a 30-60-90 triangle, the short leg (opposite of the 30° angle) is half the hypotenuse.

In a 45-45-90 triangle, the legs are the same length.

So the distance between the left wall and the laser is 60/2 = 30 m.

The distance between the right wall and the laser is 40 m.

The total distance is therefore 70 m.
