Answer:
D. Doubling the amount of charge on one of the particles
Step-by-step explanation:
Force between charged particles:
The force between two charged particles is given by:
[tex]F = \frac{kq_1q_2}{r^2}[/tex]
In which k is the coulomb constant, [tex]q_1[/tex] and [tex]q_2[/tex] are the charges and r is the distance between them.
Which of the following changes would double the force between two charged particles?
Doubling the amount of force on both particles quadriplies, as does decreasing the distance between the particles by a factor of 2(we would have a division by 1/4 which is the same as a multiplication by 4).
Increasing the distance would decrease the force.
So the correct option is D, one of the particles' charges being multiplied by 2 means that the equation for F is multiplied by 2, and thus, the force is doubled.

Let X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits. What are the possible values of X? Give three possible outcomes and their associated X values
Answer: there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values
12345 5
04555 4
00001 1
Step-by-step explanation:
Here, X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits.
Possible number of outcomes = 10 x 10 x 10 x 10 x 10
= 100,000
Possible outcomes Associated X values
12345 5
04555 4
00001 1
Hence, there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values

HELP? You put $1000 into an investment yielding 6% annual interest; you left the
money in for two years. How much interest do you get at the end of those
two years?
Answer:
$120
Step-by-step explanation:
as long as the interest is not being compounded, use the simple interest formula of:
Interest = Principal x Interest Rate x Time (in years)
I = 1000(.06)(2)
I = 120
Solve for x in IJK Algebra
Answer:
x = 60
Step-by-step explanation:
The sum of the angles in a triangle is 180
40 + x+20 + x = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x+60-60 =180-60
2x =120
Divide by 2
2x/2 =120/2
x = 60

option 2 is the answer....
The solution to the system of equations is (0, 4).
(PIC 1)
TRUE or FALSE
The solution to the system graphed below is (1, -2).
(PIC 2)
TRUE OR FALSE
Answer:
1 is false
2 is true
Step-by-step explanation:
The solution is the coordinate where the two lines intersect
For the first image the two lines intersect at (3,5) therefore (0,4) is not a solution to the system of equations
For the second image the lines intersect at (1,-2) therefore the statement is true

please help, I'll give brainlist who answers my questions ax+by=2x-3y
Answer:
a=4, b=-3
Step-by-step explanation:
If it is vertical, then the y coefficient must be equal to zero, which means b = -3. When y is 0, a*3=2*3+6, which means a=4.
Answer:
a=4
b=-3
Step-by-step explanation:
ax+by=2x-3y+6 is vertical and passes through (3,0) which means the equation should be equivalent to x=3.
If we want the y's to cancel we need -3y on lefy since we have it on right so b=-3.
So now the equation is ax=2x+6
If ax=2x+6 and x=3, by substitution property we have a(3)=2(3)+6.
Let's solve for a.
3a=6+6.
3a=12
a=12/3
a=4.
a=4
b=-3

7. Suppose you roll a fair, six-sided die 2000 times and then make a histogram of your results. Which of the following would most likely be characteristics of the histogram you would obtain?
a. Skewed-right
b. Symmetric, with a central peak
c. Skewed-left
d. Uniform
Uniform would most likely be characteristics of the histogram obtain.
What is histogram?A histogram is a rough representation of the distribution of numerical data. The term was first coined by Karl Pearson.
The histogram is the width of the area covered by the x-axis bars. These are approximate values because the histograms show the bin values instead of the original data values.
If a histogram is bell-shaped, it can be modestly described by its center and width. The center is the location of its axis of symmetry. The spread is the distance between the center and one of its inflection points.

the graph of the parabola x=2y^2-6y+3 has an x-intercept (a,0) and two y-integers (0,b) and (0,c). Find a+b+c
9514 1404 393
Answer:
6
Step-by-step explanation:
The sum of the roots (y-intercepts) of the polynomial is the opposite of the ratio of the linear term coefficient and the leading coefficient.
b + c = -(-6/2) = 3
The x-intercept is the constant: a = 3
Then the sum a+b+c is ...
a + (b +c) = 3 + 3 = 6
_____
Additional comment
The factored form of the polynomial for the given intercepts will be ...
x = 2(y -b)(y -c)
and the expanded form of that is ...
x = 2y^2 -2(b+c)y +2bc
The y-coefficient is ...
-2(b+c) = -6
b +c = 3 . . . . . . . divide by -2. This is the result used above.
We show the graph so you can add up the values of the intercepts to see that the sum is 6.

Answer:
n= 2x-6y
Step-by-step explanation:
So we might look at this and have an immediate panic attack, but if there is one thing we might look to to help us, it would be logarithms. Logarithms have many wonderful properties that will help us solve this equation. Let's get started:
1. This is the starting equation. [tex](2^{\frac{1}{2} } )^{n} =\frac{2^x}{8^y}[/tex]
2. Let's use the power to power rule on the left and multiply 1/2 by n:
a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]
3. Next, lets take the log of both sides and use the properties of logarithms:
a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]
b. [tex]log(2^{\frac{1}{2}n }) =log(\frac{2^x}{8^y})[/tex]
c. One property we are allowed to use is bringing down the exponent on the left, and another property we can use is when you have the log of a fraction, that is the same thing as the log(numerator)-log(denominator)
d. [tex]\frac{1}{2}n *log(2) =log(2^x)-log(8^y)[/tex]
e. After we do this, we can use the same property of bringing down the exponent on the right side:
f. [tex]\frac{1}{2}n *log(2) =x*log(2)-y*log(8)[/tex]
g. After this, because log(2) and 1/2 are both numbers and are multiplied by n, we can divide them from both sides, and simplify:
h. [tex]\frac{1}{2}n =\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
i. [tex]2(\frac{1}{2})n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
j. [tex]n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
k. After this, we must simplify the fraction because log(2)/log(2)=1, and log(8)/log(2)=3, these are both because 2^1=2 and 2^3=8 respectively:
l. [tex]n =2(\frac{x*log(2)}{log(2)}-\frac{y*log(8)}{log(2)} )[/tex]
m. Lastly, let's cancel and distribute:
n. [tex]n =2(x-3y)[/tex]
o. [tex]n=2x-6y[/tex]

What should be added to 7/12 to get -4/15 ?
Answer:
-17/20
Step-by-step explanation:
7/12 + x = -4/15
Subtract 7/12 from both sides
x = -4/15 - 7/12
Use 60 as common denominator
x = -16/60 - 35/60
x = -51/60
Reduce
x = -17/20

Find the measure of each acute angle
Answer:
x = 18
Step-by-step explanation:
The sum of interior angles in a triangle = 180 degrees
The given is a right triangle which means one of the angle is = 90
so the sum of 3x + 2x = 90
5x = 90 divide both sides by 5
x = 18 to find the measure of angles replace x with 18

Now we cal calculate the quantities requested
[tex]sin(2\theta)=2sin\theta cos\theta=2(-\frac{7}{25})\frac{24}{25}=-\frac{336}{625}\\\\[/tex]
[tex]cos(2\theta)=cos^2\theta-sin^2\theta=(\frac{24}{25})^2-(-\frac{7}{25})^2=\frac{527}{625}[/tex]
[tex]tan(2\theta)=\frac{sin(2\theta)}{cos(2\theta)}=\frac{-\frac{336}{625}}{\frac{527}{625}}=-\frac{336}{527}[/tex]
