Need help with this question. I tried simplifying the radical, but apparently it’s not the answer
sesenic [268]

Answer:

-1/5+(√3)/20i   or   -0.2+0.05√3i

Step-by-step explanation:

  \dfrac{-8+\sqrt{-12}}{40}=-\dfrac{8}{40}+\dfrac{2\sqrt{3}i}{40}=\boxed{-\dfrac{1}{5}+\dfrac{1}{20}\sqrt{3}\,i=-0.2+0.05\sqrt{3}\,i}

<em>Comment on answer form</em>

Satisfying the input format requirements of a computer is always problematic. One never knows if fractions or decimals are preferred, whether radicals must be simplified, and so on. If no clues are offered by general instructions, other questions, or previous experience, then it might be useful to consult your instructor.

If line GH is perpendicular to line HJ, then GJ is ____ HJ.
valentinak56 [21]

Option A: >

Solution:

Given a triangle GHJ.

The line GH is perpendicular to line HJ.

This means the triangle is a right angled triangle.

In ΔGHJ, GH is the base of the triangle and

HJ is a height of the triangle.

Then the third side must be the hypotenuse of the right triangle.

We know that by the Pythagoras theorem,

(\text {Hypotenuse})^2=(\text{Base})^2+(\text{Height})^2

(\text {GJ})^2=(\text {GH})^2+(\text {HJ})^2

This clearly shows that the hypotenuse is greater than the height.

⇒ GJ > HJ

Option A: > is the correct answer.

If line GH is perpendicular to line HJ, then GJ is > HJ.

X-4 is a factor of the function f(x)=2x^3-5x^2-11x-4
Gnoma [55]

If the one factor of the function is (x - 4). Then the other two factor of the function will be (2x + 1) and (x + 1).

<h3>What is a factorization?</h3>

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

(x - 4) is the factor of the function.

f(x) = 2x³ - 5x² - 11x - 4

Then the factor of the function will be

f(x) = 2x³ - 5x² - 11x - 4

f(x) = 2x³ + x² - 6x² - 3x - 8x - 4

f(x) = x²(2x + 1) - 3x (2x + 1) - 4(2x + 1)

f(x) = (2x + 1)(x² - 3x - 4)

f(x) = (2x + 1)(x² - 4x + x - 4)

f(x) = (2x + 1)[x(x - 4) + 1 (x - 4)]

f(x) = (2x + 1)(x + 1)(x - 4)

Help me find the area of the rhombus
atroni [7]
The equation for the area of a rhombus is A =  \frac{ (d_1)( d_2)}{2}, where d_1 and d_2 are the length of the diagonals of the rhombus, and A = area of the rhombus.

Your two diagonals are:
d_1 = 5m + 5m = 10m
d_2 = 10m + 10m = 20m

Plug these values into the equation for the area of a rhombus:
A = \frac{ (d_1)( d_2)}{2} \\&#10;A = \frac{ (10)(20)}{2} \\&#10;A =  \frac{200}{2} \\&#10;A = 100m^2

Answer: 100 m^{2}
