A conducting sphere contains positive charge distributed uniformly over its surface
The potential at the center of the sphere is the same as the potential at the surface. Then the correct option is B.
What is the potential difference?The amount of labor required to move a unit signal from one part to another is defined as the potential difference between any two points.
If the conducting sphere contains a positive charge distributed uniformly over its surface
The charge inside the sphere is zero, so the electric field inside the sphere is zero
Hence potential is same ( E = - dV/dr)
The potential at the center of the sphere is the same as the potential at the surface.

A box is in the shape of a rectangular prism. Andrea is trying to ship boxes of her homemade chocolate chip cookies. The box she is using to ship has the dimensions of 12in by 10in by 12in. Each cookie box has dimensions of 4in by 5in by 3in. How many cookie boxes will fit into the box to be shipped? Explain how you got your answer.
The 24 boxes which will fit into the large box if the box is in the shape of a rectangular prism.
What is a cuboid?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape.
We can find the volume of the box = length×width×height
Volume for the large box = 12×10×12 = 1440 cubic in
Volume for the small box = 4×5×3 = 60 cubic in
Number of cookie boxes will fit into the large box = 1440/60 = 24
Thus, the 24 boxes which will fit into the large box if the box is in the shape of a rectangular prism.

Find the mean, median, mode and range for the following data set. 1, 3, 5, 9, 8, 5, 8, 6 Mean: Median: Mode: Range:

Find the mean, median, mode and range for the following data set. 1, 3, 5, 9, 8, 5, 8, 6
[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and How to solve:-}}}[/tex]
In order to find the mean of a data set, we add all the numbers in the data set and add them, then we divide by how many there are:-
1+3+5+9+8+5+8+6
[tex]\bigstar[/tex] On simplification,
18+8+5+8+645[tex]\bigstar[/tex] Now, divide by 8, because there are 8 numbers in the data set:-
[tex]\bold{\dfrac{45}{8}\:;written\:as\:decimal\Longrightarrow5,625}}}[/tex]
We've found the mean, but we also need to find the median, mode, and range!
The median is the number in the middle, but we should first arrange the data from least to greatest:-
1, 3, 5, 5, 6, 8, 8, 9
Now pick the number in the middle, which is:-
5,6. There are 2 numbers in the middle!
So what we do is we find the mean of the two numbers in the middle:-
5+6=11
11/2 [tex]\Longleftarrow[/tex] median
Now, we don't need to find the mean anymore - the mode and range don't require the mean.
The median requires the mean only when there's an even amount of numbers in the data set.
The mode of a dataset is the number we see the most.
Here we see the number 1 once, the number 3 once, the number 5 appears twice, 6 appears one time only, 8 appears twice and, last but not least, 9 appears once.
So this data set has two modes - 5 and 8.
In order to find the range, we take the smallest number (1) and subtract it from the largest number (9), which results in
8 (range)

Reflect (-1, 4) over the x-axis.
Then translate the result up 3 units.
What are the coordinates of the final point?
If a point (-1, 4) reflected over the x-axis then translate the result up 3 units then the coordinates of the final point are (-1, -1)
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
Reflecting a point over the x-axis negates the y-coordinate, while leaving the x-coordinate unchanged.
Therefore, reflecting (-1,4) over the x-axis gives us the point (-1,-4).
Translating a point up 3 units means adding 3 to the y-coordinate. Therefore, translating (-1,-4) up 3 units gives us the point:
(-1, -4 + 3) = (-1, -1)
So the final point is (-1,-1).
Hence, if a point (-1, 4) reflected over the x-axis then translate the result up 3 units then the coordinates of the final point are (-1, -1)

I need help, will give brainliest to whomever answers!! thanks!!!
Step-by-step explanation:
in such problems with just equations we always need to have the main (optimization) equation or condition, and then usually some constraint equations.
the constant equations allow us typically to express one variable through another, until we have only one variable for the optimization equation. then we find the zeros of the first derivative of that functions and find the needed maximum or minimum if needed via the second derivative.
now if we have inequalities, it is even easier, I think.
we find the corners of the shaded area that must contain our minimum or maximum by finding the intersections of the delimiter lines. the optimum must be one of the corners.
and then we try the coordinates of the different corners in the optimization equation and see, which one delivers the highest or lowest value. and we are done.
a.
x + y <= 240
y >= 4x
b.
500x + 450y = profit
theoretically we have 3 corners to test
(0, 0)
(0, 240)
(48, 192)
(0, 0) is clearly the minimum, profit 0.
(0, 240) gives
450×240 = $108,000
(48, 192) gives
500×48 + 450×192 = 24000 + 86400 = $110,400
that is the maximum.
so, the farmer makes the most profit under the given constraints, if he plants 48 acres corn and 192 acres sprouts.

[tex]V_{shipping\: container}=2,419,200\:in^3[/tex]
A. 4032 boxes
SA = 460 sq in
Step-by-step explanation:
For shipping container:
l = 240 in, w 84 in, h = 120 in
[tex]V_{shipping\: container}=lwh[/tex]
[tex]\implies V_{shipping\: container}=240\times 84\times 120[/tex]
[tex]\implies V_{shipping\: container}=2,419,200\:in^3[/tex]
For box:
l = 10 in, w = 5 in, h = 12 in
[tex]V_{box}=lwh[/tex]
[tex]\implies V_{box}=10\times 5\times 12[/tex]
[tex]\implies V_{box}=600\:in^3[/tex]
[tex]\frac{V_{shipping\: container}}{V_{box}}=\frac{2,419,200}{600}[/tex]
[tex]\frac{V_{shipping\: container}}{V_{box}}=4032[/tex]
Surface area of box
= 2(lw + lh +wh)
= 2(10*5+ 10*12+ 5*12)
=2(50+120+60)
=2(230)
= 460 sq in
An architect-designed an attic space in the shape of a square pyramid. After reviewing the design, he decided to make a second design for an attic space in the shape of an oblique pyramid. He created models of both designs as shown.
Both models were cut horizontally at the same height, finding the cross-sections with the same area. Several other horizontal cross-sections were analyzed and found to have the same area. Both pyramid models also have the same height, a.
Which formula would allow the architect to calculate the volume of his second attic space design?
A.V=s^2a
B.V=1/2s2b
C.V=1/3scb
D.V=1/3s2a
The formula that would allow the architect to calculate the volume of his second attic space design is V = 1/3s²b. Option D is correct.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The formula for the volume of an oblique pyramid is V = 1/3 * base area * height. In this case, the base of the oblique pyramid is the shape of the cross-section, which is a square. So, the formula becomes V = 1/3 * s^2 * height. The given information states that the height is "a", which is the same for both pyramid models.
Therefore, the formula for calculating the volume of the second attic space design becomes V = 1/3 * s² * a.

The answer is almost certainly 5 years. People might, however, pursue a Master of Architecture degree, which takes two to three years to accomplish.
Step-by-step explanation:
Architecture is a five-year degree that requires a keen interest in the topic. A five-year undergraduate architecture degree, known as a B. Arch., or a two- or three-year post-college master's program, known as an M. Arch., are the two alternatives for those who wish to get an architectural degree that will help them get licensed as an architect. You'll have to labor every day and night. Of course, your performance in class will have an impact. Some instructors may offer homework that are beyond your grasp and abilities.
