If an atom loses a neutron, what happens to the overall electric charge
Answers
For atoms, all you need to know this. You have a nucleus, which is compromised of protons and neutrons. Electrons orbit the nucleus.
Protons have a positive charge of +1
Neutrons have a neutral charge
Electrons have a negative charge of -1
Now, neutrons are part of the nucleus, meaning they add overall mass/weight to the atom. If you were to take one of these away, it would STILL be the same element. Elements are defined truly by their protons, not neutrons.
So, take away a single neutron, the mass will lower, but it would still be the same element.

what is the slope of a line that is perpendicular to the line that passes through (1,0) and is parallel to y=3x+5
Answers
We need to first find the slope. Since we're already given an equation, we can simply find it within there :)
We're given an equation in slope intercept form (y = mx + b) so we can simply look in the "m" spot. Therefore, we know that the slope is 3.
Since our slope is perpendicular to the given line, we must find the negative reciprocal of the slope.
A negative reciprocal is simply a number flipped over and then given a negative (or a negative is removed).
An example is here : slope = 8 → negative reciprocal of slope = -1/8
So, our negative reciprocal of "3" is -1/3.
Therefore, our new slope is -1/3.
Now, since it passes through (1, 0) then this is how we are going to find out y-intercept to input it into our new equation.
y = mx + b
Simply plug in everything (including slope and y)
0 = (-1/3)(1) + b
Simplify.
0 = -1/3 + b
Add 1/3 to both sides.
1/3 = b
Therefore, our y-intercept is b.
Now that we have all of the needed variables for our new equation, simply plug everything into an all new equation :)
y = mx + b
y = -1/3x + 1/3

The equation y = x + 1 defines the relationship between x and y, where x is the input and y is the output. Which statements about the graph of this relationship are true? Select two that apply.
A.The graph is a curved line.
B.The graph is a straight line.
C.the graph is a vertical line.
D.The graph represents a function.
E.The graph has no negative outputs.
F.The graph passes through the origin.
Answers
All in all, your answers are B and D.
Let's go through all of our options.
A) It's defintely not curved; it's written in slope intercept form and is indeed a straight line.
B) Yes, the graph is a straight line. Although it's at an angle, it has no curves or flaws, and is completely straight.
C) The graph is not vertical. It has a y intercept and slope and therefore isn't. That's because it has a rate of change, and it crosses the y axis at some point depending on the slope, or rise over run. Vertical lines really don't have that.
D) Yes, the graph is a function. This is because it does not have two x values for one y, and does not fail the straight line test, which states that you can place a straight line anywhere on the graph and it can only go through one point.
E) This is false. If we put in -5 as our input, we add 1 and get -4, which is a negative output. Your output here depends on the input you put in, and the sign usually remains considering it's +1.
F) This graph does not pass through the origin. This is because the origin has a point at 0,0 and since it's x+1, it would be 0,1 instead because your output is adding one to that 0.

This figure is made up of a quadrilateral and a semicircle.
What is the area of this figure?
Use 3.14 for pi. Round your answer to the nearest tenth.
A.) 22.8 units²
B.) 40.4 units²
C.) 45.5 units²
D.) 74.5 units²
Answers
Answer:
The correct option is B. The area of the figure is 40.4 units².
Step-by-step explanation:
The line AB divides the figure in two parts one is a rectangle and another is semicircle.
The distance formula is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The length of AB is
[tex]AB=\sqrt{(2+3)^2+(4-2)^2}=\sqrt{25+4}=\sqrt{29}[/tex]
The length of AD is
[tex]AD=\sqrt{(-1+3)^2+(-3-2)^2}=\sqrt{4+25}=\sqrt{29}[/tex]
Since AB=AD, therefore ABCD is a square. The area of the of square is
[tex]A_1=a\times a=\sqrt{29}\times \sqrt{29} =29[/tex]
The area of square is 29 units².
The area of a semicircle is
[tex]A_2=\frac{\pi}{2}r^2[/tex]
Since AB is the diameter of the semicircle, therefore the radius of the semicircle is
[tex]r=\frac{d}{2}=\frac{\sqrt{29}}{2}[/tex]
The area of the semicircle is
[tex]A_2=\frac{3.14}{2}(\frac{\sqrt{29}}{2})^2=40.3825[/tex]
The area of the figure is
[tex]A=A_1+A_2=29+11.2825=40.3825\approx 40.4[/tex]
Therefore the area of the figure is 40.4 units². Option B is correct.

A. $829.23
B. $884.56
C. $807.81
D. $876.09
Answers
Answer:
Option B is the answer.
Step-by-step explanation:
The formula for EMI is :
[tex]\frac{p\times r\times (1+r)^{n} }{(1+r)^{n} -1}[/tex]
Here p = 162000
r =[tex]5.15/12/100=0.004292[/tex]
n = [tex]30\times12=360[/tex]
Now putting the values in the formula we get,
[tex]\frac{162000\times 0.004292\times (1+0.004292)^{360} }{(1+0.004292)^{360} -1}[/tex]
[tex]\frac{162000\times 0.004292\times (1.004292)^{360} }{(1.004292)^{360} -1}[/tex]
= $884.60 close to option B.
So, option B is the answer.

Given a triangle with vertices U(6, −1), W(0, −5), and X(4, −9), and Y is the midpoint of segment UW and Z is the midpoint of segment WX comma what is the length of YZ?
Answers
Here we have to use the distance formula
Please see the image attached with the solution , for the figure
Firstly we have to find the length of line segment XU
and the triangle has a property that the length of line segment that connects the midpoint of the two sides is half the length of the third side.
It means here
Length of YZ = half the length of XU
So lets find the length of XU
[tex] \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}= \sqrt{(6-4)^2 +(-1+9)^2} =\sqrt{4+64} [/tex]
[tex] =\sqrt{68} [/tex]
[tex] =2\sqrt{17} [/tex]
Now the length of YZ = half of [tex] =2\sqrt{17} [/tex]
So length of YZ = [tex] =\sqrt{17} [/tex]

y 2 + 5y Choose the constant term that completes the perfect square trinomial.
Answers
The constant term that completes the perfect square trinomial is 6.25.
Explanation:To complete the square for the given expression y² + 5y, we take half of the coefficient of the linear term (5/2) and square it to find the value to be added. Half of 5/2 is 5/4, and squaring it gives 25/16. Adding 25/16 to the expression yields a perfect square trinomial: y² + 5y + 25/16 = (y + 5/4)².
To write it in standard form, we convert 25/16 to 1.5625. Therefore, the constant term that completes the perfect square trinomial is 1.5625, or 6.25 when expressed as a decimal.
