In the following passage we have proven the Pythagoras' theorem.

What is Pythagoras' theorem?

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Here given in the question that one side of the wall 5 feet

So as it is a rectangular bedroom it can be split into 2 right-angled triangles.

So the hypotenuse of the triangle is 13 feet

Now using the Pythagoras theorem we can find out the length of the other wall

b²=h²-p²

AB² + BC² = AD × AC + CD × AC

AB² + BC² = AC (AD + CD)

Since, AD + CD = AC

Therefore, AC² = AB² + BC²

So we have p² + b² = h².

Hence, we prove the Pythagoras theorem using two triangle.

If two quantities have same units, they will be comprised of the same basic physical quantities and hence their dimensions will be same. Same dimensions do not represent the same physical quantity. For example, The kinetic energy and the potential energy are measured in the same units but they possess different physical quantities.

The minimal set of coordinates required to specify any point within a mathematical space is known as the dimension of the space in physics and mathematics. As a result, a line has a dimension of one because a point on it can be specified by a single coordinate, such as the point at 5 on a number line.

Two quantities with the same units will be made up of the same fundamental physical quantities, resulting in identical dimensions. The same physical quantity does not have the same dimensions. For instance, although having different physical properties, kinetic energy and potential energy are measured in the same units.

Equation is C=25n + 2500 And The total cost to produce 3000 toys is $77,500 And With $32500, a total of 1200 toys can be produced

A linear equation is what, exactly?

An algebraic equation with only a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

A) Lets have linear equation y=mx+b,

C (total cost) = y and n (number of toys) =x.

The original development cost plus the production cost of each toy would equal the overall cost of creating n toys.

Because m is multiplied by n, the number of toys, the cost to produce a toy will equal m.

Due to the fact that b is a constant and its value is unaffected by the quantity of toys, it will always equal the development cost.

Therefore, C=25n + 2500

B) by above, equation put n=1750

C= 25(3000) + 2500

C= $77,500

C) Now, again by same equation, but C instead of n.

=> 32500= 25n +2500

=> 30000=25n

=> n = 1200

t-distribution in the bank or restaurant to get the customer arrival time is a b) normal distribution.

The t-distribution is defined by degrees of freedom. These are related to sample size. The t distribution is most useful when the sample size is small, the population standard deviation is unknown, or both. As the sample size increases, the t-distribution will become more normal.

The t distribution is the continuous probability distribution of z scores when the estimated standard deviation is used in the denominator instead of the true standard deviation. The purpose of the t-test is to compare a specific characteristic that describes the groups, and the means will be representative of the populations that are normally distributed.

Answer:

Step-by-step explanation:

You want the statements that describe the function f(x) = 2(x -4)⁴.

The degree of the function is the exponent: 4. This means the function has 4 zeros.

The maximum number of relative extrema is 1 less than the degree. The function has at most 3 relative maximums or minimums.

The even degree means both ends of the graph go in the same direction.

The leading coefficient of 2 is positive, so the ends of the function will go up.

In the parent function f(x) = x⁴, the value of x has been replaced by (x-4). This causes the graph to be translated 4 units to the right.

__

Additional comment

This function has a zero at (4, 0) with multiplicity 4. There is a flat spot where the graph touches, but does not cross, the x-axis. As a consequence, there is only one minimum and no relative maximums.

Answer: x = 10

Step-by-step explanation:

x + 6 + 3x = 5x - 4

First you want to group your like values together

6 +4 = 5x - 3x - x

Note that when any value crosses the = sign, The sign in front of it (+/-) changes. (e.g. -4 changes to +4 after it crosses the = sign)

Then work out your values

10 = x

Also note that x is the same as 1x. So you minus 3x from 5x to get 2x and 2x minus 1x is equal to 1x which is the same as x.

Using unit I, calculate the average waiting time of customers in the wash line (μ for unit I = 12 per unit).

For unit II at 15 per hour

if waiting time is the only criterion, unit II should be purchased. But before we make the final decision, we must look at the profit differential between both units.

With unit I, some customers would balk and renege because of the 5 minute wait. And, although this greatly complicates the mathematical analysis, we can gain some estimate of lost sales with unit I by increasing Wq = 5 minutes and solving for λ. This would be the effective arrival rate of customers.

Therefore, because the original estimate of λ was 10 per hour, an estimated 2 customers per hour will be lost.

Lost profit of 2 costumers per hour × 14 hours × 1/2 ($0.70 fill-up profit + $0.40 wash profit) = $15.40 per day.

Because the additional cost pf unit II over unit I is only $4 per day, the loss of $15.40 profit obviously warrants installing unit II.

The original five-minute maximum wait constraint is satisfied by unit II.

Therefore, unit III is not considered unless the arrival rate is expected to increase.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the total ounces of ingredients in the cake be = 44 ounces

The ratio of flour to sugar is = 6 : 5

So , the amount of flour in 44 ounces = 6x

The amount of sugar in 44 ounces = 5x

And , the equation is

6x + 5x = 44

On simplifying the equation , we get

11x = 44

Divide by 11 on both sides , we get

x = 4

So , the total amount of sugar in 44 ounces of ingredients = 5x

Substitute the value for x = 4 , we get

Total amount of sugar in 44 ounces of ingredients = 20 ounces

And ,

Let the total ounces of ingredients in the new cake be = 91 ounces

The ratio of flour to sugar is = 7 : 6

So , the amount of flour in 91 ounces = 7y

The amount of sugar in 91 ounces = 6y

And , the equation is

7y + 6y = 91

On simplifying the equation , we get

13y = 91

Divide by 13 on both sides , we get

y = 7

So , the total amount of sugar in 91 ounces of ingredients = 6y

Substitute the value for y = 7 , we get

Total amount of sugar in 91 ounces of ingredients = 42 ounces

Therefore , the extra ounces of sugar the baker added to the new cake is =

Total amount of sugar in 91 ounces of ingredients - Total amount of sugar in 44 ounces of ingredients

The extra ounces of sugar the baker added to the new cake is = 42 - 20

Extra ounces of sugar the baker added to the new cake is = 22 ounces

Hence ,

The amount of ounces of sugar she added to the new cake is 22 ounces

In the given question, in 2006, 68.1 million people subscribed to cable television. in 2013, that number had decreased to 57.1 million.

We have to find the percent decrease in the number of cable TV subscribers from 2006 to 2013.

The number of subscriber in 2006 is 68.1 million.

The number of subscriber in 2013 is 57.1 million.

Then the percent decrease in the number of cable tv subscribers from 2006 to 2013 is

Percent decrease in the number of cable TV subscribers = (subscriber in 2006 - subscriber in 2006)/subscriber in 2006 *100

Percent decrease in the number of cable TV subscribers = (61.4-50.4)/61.4 *100

Percent decrease in the number of cable TV subscribers = 11/61.4 *100

Percent decrease in the number of cable TV subscribers = 0.1792*100
