➷ E = k/d^2

k is the constant

Substitute the values given in:

29.388 = k/2.1^2

Multiply both sides by 2.1^2 to get the constant

k = 129.60108

The equation that models this is:

E = 129.60108/d^2

Substitute the values in:

4.614 = 129.60108/d^2

Divide both sides by 4.614 to get d^2

d^2 = 28.0886606

d = 5.29987364

This can be rounded to 5.3

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

What are the solutions of 2x2- 6x+5=0?
Scrat [10]

Answer:

$x_{1}=\frac{3}{2}+\frac{i}{2}\\$

$x_{2}=\frac{3}{2}-\frac{i}{2}$

Step-by-step explanation:

It is a Quadratic Equation

2x^2-6x+5=0

Once it cannot be easily factored, you solve it using the quadratic formula or completing the square. I will use the quadratic formula.

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{-(-6)\pm\sqrt{(-6)^2-4\cdot 2\cdot 5}}{2\cdot 2}$

The discriminant is negative, therefore we got complex solutions.

\Delta= \sqrt{-4}= \sqrt{4i}  =2i

$x=\frac{6\pm 2i}{4}$

$x_{1}=\frac{3+i}{2} $

$x_{2}=\frac{3-i}{2} $

Now, just rewrite the roots in standard complex form

$x_{1}=\frac{3}{2}+\frac{i}{2}\\$

$x_{2}=\frac{3}{2}-\frac{i}{2}$
