The average diameter of a can in inches is 2.4 inches.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a 12-ounce soda can has a height of 4.875 inches.

We know that, 1 ounce = 1.805 cubic inches

Here, 12 ounce = 21.6563 cubic inches

As we know, volume of cylinder is πr²h.

Now, 21.6563 = 3.14×r²×4.875

21.6563 =r²×15.3075

r²=21.6563/15.3075

r²=1.414

r=1.2 inches

Then, diameter = 2.4 inches

Therefore, the average diameter of a can in inches is 2.4 inches.

The surface area of the square pyramid is given by S = 16 inches²

The total surface area is the summation of the areas of the base and the three other sides. A = B + ( 1/2 ) ( P x h ), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid

Surface Area of Pyramid = B + ( 1/2 ) ( P x h )

Given data ,

Let the surface area of the square pyramid be S

Now , the equation will be

The surface area of the square pyramid = surface area of square + 4 ( area of triangles )

And , the side length of square a = 2 inches

So , the area of square = a² = 4 inches²

The height of the triangle h = 3 inches

The base of the triangle = a = 2 inches

So , the area of the triangle = ( 1/2 ) x a x h

On simplifying the equation , we get

The area of the triangle = ( 1/2 ) x 2 x 3 = 3 inches²

So , the area of 4 triangles = 4 x 3 = 12 inches²

Now , The surface area of the square pyramid S = 4 inches² + 12 inches²

On simplifying the equation , we get

The surface area of the square pyramid S = 16 inches²

Hence , the surface area of pyramid is 16 inches²

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Salut/Hello!

Definition of a function: In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

To make it more simple imagine a empty box with 2 holes ( one at the top and the other at the bottom ) and you insert a ball in the top hole and it falls thru the bottom hole.
When the ball falls inside the box (function) thru the top hole it'll be called
"input ball". The inside of the box can be called "function box:"
So once the ball falls out of the box thru the bottom hole it'll be called "output box(ball)".

Example: (using the image)
1. In this diagram of a function we have the domain X = {A,B,C} and codomain Y = {1,2,3} and it's defined with the set of ordered pairs  {(A, 2), (B, 1), (C, 3)} and the set range is {A,B,C}

2. In this diagram of a function we have the domain A = {1,2,3} and codomain B = {X,Y,Z} and it's defined with the set of ordered pairs {(1, Y), (2, Y), (3, Z)} and the set range is {Y,Z}

3. In this diagram, representing the set of pairs {(1,D), (2,E), (2,F)} does not define a function because 2 is the first element in more than one ordered pair, but also because 3 is not the first element of any ordered pair.


Answer:
Relation 1: Function
Relation 2: Not a function (-8 is the first element in more than one ordered pair)
Relation 3: Function (a function can contain ordered pairs that include the same value for both the domain and codomain)
Relation 4: Not a function (5 is the first element in more than one ordered pair)

Answer:

Step-by-step explanation:

The total length of the road is 27 miles, and since each cottage is separated from its neighbor by a distance of 1, 2, 3, 4, ..., 25, or 26 miles, the total length of the road occupied by these distances must sum to 27 miles. This is because the road connects the six cottages.

One possible distribution is:

Cottage 1 and 2 are 1 mile apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 4 and 6 are 7 miles apart.

...

Cottages 1 and 6 are 25 miles apart.

Cottages 2 and 5 are 26 miles apart.

A second possible distribution can be obtained by reversing the order of the distances between the cottages. That is:

Cottages 2 and 5 are 26 miles apart.

Cottages 1 and 6 are 25 miles apart.

Cottages 4 and 6 are 7 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 1 and 2 are 1 mile apart.

There may be other possible distributions, but these two demonstrate that there are multiple ways to arrange the distances between the cottages while still satisfying the constraint that the distances must sum to 27 miles.

To find the time it takes for a car to stop from a velocity of 35 m/s using a braking force of 4000 N, we can use the following formula:

vf = vi + at

where

vf = final velocity (0 m/s in this case, since the car is stopping)

vi = initial velocity (35 m/s)

a = acceleration, which can be calculated as a = F/m, where F is the braking force (4000 N) and m is the mass of the car (2000 kg)

t = time

Rearranging the formula:

t = (vf - vi)/a = (0 - 35) / (4000 / 2000) = (35) / (2) = 17.5 s

Answer:

It takes the car 17.5 seconds to stop from a velocity of 35 m/s with a braking force of 4000 N.

61 percent of the 8th graders estimated they spend less than an hour a day on social media.

To find the percentage of 8th graders who estimated they spend less than an hour a day on social media, we need to calculate the proportion of 8th graders who answered "less" and then convert it to a percentage.

There were 12 + 19 = 31 8th graders in the sample.

Out of these 31 8th graders, 19 answered "less" and 12 answered "more".

So, the proportion of 8th graders who answered "less" is 19/31 = 0.61290323.

To convert this proportion to a percentage, multiply it by 100:

0.61290323 * 100 = 61.290323 (rounded to 2 decimal places).

Finally, rounding to the nearest whole number percent, we get:

61.290323 rounded to the nearest whole number percent = 61%

In order for Lashonda to achieve a final average of 80, she must receive a score of 86 on her last exam.

Score is a numerical value or result that is used to indicate the performance or achievement of an individual or team in a particular activity or game. A high score indicates excellence or success while a low score indicates the opposite. Score is often used to track progress and can be used to compare individuals or teams against each other. Score can also be used as a measure of progress or improvement.

To calculate her score, we add up all of her previous exam scores (95 + 82 + 89 + 70 + 76) and divide them by 6 (the number of exams taken). This gives an average of 81. We then subtract the current average (81) from her desired average (80) to arrive at the score she must receive on her last exam (86).

In which:

The highest grade is for large values of t, meaning that e^(-0.24t) = 0, and thus:

P(t) = 36 + 56

P(t) = 92.

If the student does not study, we have that t = 0, hence the grade is given as follows:

In other words, it is impossible to describe an irrational number as the ratio of two integers. When there is an irrational relationship between the lengths of two line segments, the line segments are also said to be incommensurable. This means that there is no length, no matter how short, that could be used to express the lengths of the two supplied segments as integer multiples of itself.

In mathematical terms, the equation e^-2.5 = h states that the exponential value of -2.5 (e^-2.5) is equal to the variable h. To convert this equation into its logarithmic form, we can take the natural logarithm of both sides of the equation. The natural logarithm, represented by the function ln, returns the power to which e must be raised to obtain a given number.

So, taking the natural logarithm of both sides of the equation, we have:

ln(e^-2.5) = ln(h)

Since ln(e^x) = x, we can simplify the left side of the equation:

ln(h) = -2.5

Thus, the logarithmic equivalent of the equation e^-2.5 = h is ln(h) = -2.5.

The logarithmic equation ln(h) = -2.5 can be interpreted as follows: the natural logarithm of h is equal to -2.5. In other words, h is the result of raising e to the power of -2.5. To find the value of h, we can use the exponential function:

h = e^-2.5

Therefore, the original equation e^-2.5 = h and the logarithmic equation ln(h) = -2.5 are mathematically equivalent and can be used interchangeably.

It is worth mentioning that logarithms are used in many areas of mathematics and science, including engineering, finance, and physics. They allow us to simplify complex calculations and to solve problems that are otherwise difficult or impossible to solve.
