Solve for x. (X-8)^2=-8

Mathematics
1 answer:
VikaD [51]4 years ago
7 0

Answer:

x = 8 ± 2i√2

Step-by-step explanation:

√-1 is imaginary number i

Step 1: Write equation

(x - 8)² = -8

Step 2: Solve for <em>x</em>

  1. Square root both sides: x - 8 = √-8
  2. Factor out negative: x - 8 = √-1 · ±√8
  3. Simplify: x - 8 = ±i2√2
  4. Add 8 to both sides: x = 8 ± 2i√2

Find the area or this triangle ​
Arlecino [84]

Answer:

Area of triangle = 15 square units

Step-by-step explanation:

We need to find area of the triangle, given the vertices:

A=(4,0)

B=(1,5)

C=(7,5)

The formula used is: Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))

We have: x_1 =4, y_1 =0, x_2 =1, y_2=5, x_3=7 , y_3=5

Putting values and finding area

Area\:of\:triangle=\frac{1}{2}(x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2))\\Area\:of\:triangle=\frac{1}{2}(4(5-5)+1(5-0)+7(0-5))\\Area\:of\:triangle=\frac{1}{2}(4(0)+1(5)+7(-5))\\Area\:of\:triangle=\frac{1}{2}(0+5-35)\\Area\:of\:triangle=\frac{1}{2}(-30)\\Area\:of\:triangle=-15

We will be ignoring negative sign, because area of triangle is positive.

So, Area of triangle = 15

Can someone please help and explain how to use the Pythagorean Theorem to prove a triangle is a right triangle.
marin [14]

Hi there!

For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2

And then find the root of the hypotenuse.

For example,

15^2 + 8^2 = the hypotenuse^2

Which equals, 225 + 64 = 289

Square root of 289 = 17

Please mark me brainliest if this helps!

Have a wonderful day!

Plz help me with number 13 plz I need your help plz help me I’m begging you plz help me plz it’s an emergency plz I’m begging yo

<h2>A = 0.625</h2>

There are 8 points between 1 and 0 so divide 1 by 8.

1 / 8 = 0.125

Each point has a value of 0.125.

You can minus 0.125 from 1 until you reach A.

Or you can multiple 0.125 by the number of points from 0 to A, including A.

1 - 0.125 - 0.125 - 0.125 = 0.625

0.125 * 5 = 0.625

<h2>A = 0.625</h2>
