SOLVE x^4 − 15x^2 − 16 = 0 What are the roots of the equation?

kakasveta [241]

Answer:

roots : 4, -4, i, -i

Step-by-step explanation:

This gets a bit tricky.

We have to substitude x^2 as u in this problem.

Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get

u^2 - 15u - 16 = 0

( u - 16) (u + 1)

U = 16

U = -1

This is not the end of the problem.

Now we have to substitute x^2 back to u.

x^2 = 16 --> we get the roots 4 and -4

x^2 = -1 --> we get the roots i and -i

Find the area of the figure.

andrezito [222]

Answer:

area of figure = area of rectangle + area of triangle

area of rectangle= length × width

6×4

24yd²

area of triangle= 1/2×base×height

1/2×3×4

3×2

=6yd²

area of figure= 24+6

= 30yd²

A central angle of a circle measures 42 degrees. What else can be shown to measure 42 degrees?

Slav-nsk [51]

Answer:

Vertically opposite angles

Step-by-step explanation:

Given

$\theta = 42^\circ$

Required

What else can measure $\theta = 42^\circ$

The question has missing options. So, I will give a general explanation.

Using the attached image as a point of reference.

Given that:

$\theta = 42^\circ$

The value of b is calculated as:

$b = \theta$

Because b and $\theta$ are vertically opposite angles

This gives:

$b = 42^\circ$

So, one possible answer to the question is a vertically opposite angle
