<span>Assuming that the particle is the 3rd particle, we know that it’s location must be beyond q2; it cannot be between q1 and q2 since both fields point the similar way in the between region (due to attraction). Choosing an arbitrary value of 1 for L, we get </span>

<span>
k q1 / d^2 = - k q2 / (d-1)^2 </span>

Rearranging to calculate for d:

<span> (d-1)^2/d^2 = -q2/q1 = 0.4 </span><span>
<span> d^2-2d+1 = 0.4d^2 </span>
0.6d^2-2d+1 = 0  
d = 2.72075922005613 
d = 0.612574113277207 </span>

<span>
We pick the value that is > q2 hence,</span>

d = 2.72075922005613*L

<span>d = 2.72*L</span>

Point A lies outside of plane P. How many lines can be drawn perpendicular to plane P through point A?
Ivanshal [37]

<em>Answer</em>


D) 1


<em>Explanation</em>

A perpendicular line makes a angle of 90° with a line or a plane.

If a line is to be drawn from a point to a line or a plain it can only be one. In this case a line is to be drawn through a point A to a plane P. If the line is to be perpendicular, then is is only one.


From the choices, the appropriate answer is D) 1

If Charlotte spent 25% more on furniture than she will on flooring, how much did she spend on furniture?
SashulF [63]

Answer:

Charlotte spent   x + 0.25x on furniture

Step-by-step explanation:

Given:

Charlotte spent 25% more on furniture than she will on flooring

To Find:

Amount spent on furniture = ?

Solution:

Let the amount spent on flooring be x

and the amount spent on furniture be y

25% more on furniture than she spent on flooring can be written as

=>25% of x

So the cost spent on furniture will be

=>y= cost spent on flooring +  25% of cost spent on flooring

=>y= x + 25% of x

=>y=x + \frac{25}{100} \times x

=> y=x + 0.25x

Onto
Nesterboy [21]

Answer:

No

Step-by-step explanation:

To obtain the inverse function

let y = f(x) and rearrange making x the subject, that is

y = 3x + 1 ( subtract 1 from both sides )

y - 1 = 3x ( divide both sides by 3 )

\frac{y-1}{3} = x

Change y back into terms of x, thus

f^{-1}(x) = \frac{x-1}{3}
