Answer:

Step-by-step explanation:

1.The square root function is a mathematical function that returns the positive number that, when multiplied by itself, gives the original number. It can be represented using the symbol √ or using the exponent 1/2. The cube root function is a mathematical function that returns the number that, when multiplied by itself three times, gives the original number. It can be represented using the symbol ∛ or using the exponent 1/3.

2.The ancient civilizations of Babylonia, Greece, and India all independently discovered the square root function. The concept of cube root was first mentioned in the ancient Indian text "Sulbasutras" around 800 BCE. The Greek mathematician Euclid also described the cube root function in his work "Elements" around 300 BCE.

3.The square root function is used in many areas of mathematics and science, including geometry, trigonometry, and physics. In real life, square root functions are used in many areas such as engineering, architecture, and finance. For example, in engineering, square root functions are used to calculate the stress and strain on materials. In architecture, square root functions are used to calculate the area of a building or room. In finance, square root functions are used to calculate the volatility of an asset. Similarly, cube root function is used in mathematics, physics, engineering, economics, and other fields. It is used to find the cube root of a number, to find the volume of a cube, to solve equations, and to calculate the cube root of a complex number.

x = -5.7778

Step-by-step explanation:

1)  8x + 8 + x -2 = 48 (You multiply the -4 into both -2x and -2, thus getting rid of the brackets)

2) 9x + 6 = -48 (Add the two values of x (8x + x) and then subtract the 2 from 8  = 6)

3) 9x =-46 - 6 (Move the 6 mover, which will change its sign from a (+) to a (-6))

4) 9x = -52 (Do the expression, and you get -52)

5) x = -52 / 9 (Isolate the x, by dividing both sides by it)

6) x = -5.7778 (Round the answer)

Step-by-step explanation:

Our assumption that there exists a Mersenne prime greater than 3 with a composite k value must be false. All Mersenne primes greater than 3 must have a corresponding prime integer k.

All Mersenne primes greater than 3 have the following property: their corresponding integer k must also be prime. This can be proven using a proof by contradiction.

Assume there exists a Mersenne prime greater than 3 with a composite k value. This means that k can be expressed as the product of two integers, p and q, both greater than 1.

We can then substitute 2pq − 1 for n in the equation for a Mersenne prime (n = 2k − 1), giving us:

n = 2k − 1
n = 2pq − 1

We can then factor this expression as:

n = (2p + 1)(2q − 1)

Since p and q are both greater than 1, we know that (2p + 1) and (2q − 1) are both greater than 2. This means that n has factors other than 1 and itself, which contradicts the definition of a prime number.

The value of cosec A / cot A - sec A, we'll first express cosec A, cot A, and sec A in terms of the given value of tan A.The value of cosec A / cot A - sec A, using the given value of tan A = 4/3, is 1 + √(9/7)/3.

We know that cosec A is the reciprocal of sin A, and sin A is the reciprocal of cosec A. Similarly, cot A is the reciprocal of tan A, and sec A is the reciprocal of cos A.

Using the Pythagorean identity, sin^2 A + cos^2 A = 1, we can find the value of cos A. Since tan A = 4/3, we can find sin A as well.

Given:

tan A = 4/3

Using the Pythagorean identity:

sin^2 A + cos^2 A = 1

We can solve for cos A as follows:

(4/3)^2 + cos^2 A = 1

16/9 + cos^2 A = 1

cos^2 A = 1 - 16/9

cos^2 A = 9/9 - 16/9

cos^2 A = -7/9

Taking the square root of both sides, we get:

cos A = ± √(-7/9)

Since cos A is positive in the first and fourth quadrants, we take the positive square root:

cos A = √(-7/9)

Now, using the definitions of cosec A, cot A, and sec A, we can find their values:

cosec A = 1/sin A

cot A = 1/tan A

sec A = 1/cos A

Substituting the values we found:

cosec A = 1/sin A = 1/√(1 - cos^2 A) = 1/√(1 - (-7/9)) = 1/√(16/9) = 1/(4/3) = 3/4

cot A = 1/tan A = 1/(4/3) = 3/4

sec A = 1/cos A = 1/√(-7/9) = -√(9/7)/3

Now, let's calculate the expression cosec A / cot A - sec A:

cosec A / cot A - sec A = (3/4) / (3/4) - (-√(9/7)/3)

= 1 - (-√(9/7)/3)

= 1 + √(9/7)/3

Therefore, the value of cosec A / cot A - sec A, using the given value of tan A = 4/3, is 1 + √(9/7)/3.

Step-by-step explanation:

So we know that a shape with 4 angles equal 360 degrees and this has 4 angles. Since we know that 4x is one and 2x is one We cna use the vertical angles to find the other two. Since 4x is opposite of an unknown side it is also 4x becuase vertical angles are equal becuase they are opposite sides of each other. Same thing with 2x

Now add them all up

4x+4x+2x+2x which will equal 12x

Answer:

a: The answer is 36 units squared

b: You would lose four square units

Step-by-step explanation:

a: You can count the pieces showing, but you also have to add the amount you cannot see, which would give you a total of 36 units squared (since it doesn't say what each unit is represented by

b: The bottom pieces that originally were not showing would now be showing, but you would lose the ones above it. These cancel out from each other. There are 4 other sides that are now no longer showing since the others that are still showing still were anyways, so there are 4 units squared missing from the surface area when you remove the top two blocks.

E[X] = 11/12, P(A) = 1/2, E[X|A] = 4/3

fX|A (x) = {2/3 0 Less then or x Less than or 2 0 otherwise

E[Y] = 4/3, var(Y) = 4/5

The expected value of X, denoted as E[X], can be calculated by integrating the product of the random variable X and its probability density function (pdf) fX(x) over its entire range. In this case, the pdf is defined as fX(x) = x/4 for 1 ≤ x < 3 and 0 otherwise. Integrating x*(x/4) over the range [1, 3] yields E[X] = 11/12.

The probability of event A, denoted as P(A), can be determined by integrating the pdf fX(x) over the range where X < 2. Since fX(x) is equal to x/4 for 1 ≤ x < 2 and 0 otherwise, integrating (x/4) over the range [1, 2] gives P(A) = 1/2.

The conditional pdf fX|A(x) represents the probability density function of X given the event A has occurred. In this case, when A occurs (X < 2), fX|A(x) is equal to 2/3 for 0 ≤ x < 2 and 0 otherwise.

The expected value of X given event A, denoted as E[X|A], can be calculated by integrating the product of X and fX|A(x) over its range. Integrating x*(2/3) over the range [0, 2] yields E[X|A] = 4/3.

The random variable Y is defined as the square of X. To find E[Y], we need to calculate the expected value of Y. Since Y = X^2, we can use the linearity of expectation and compute E[Y] as E[X^2]. From the previously calculated E[X], E[Y] is equal to (11/12)^2 = 121/144.

The variance of Y, denoted as var(Y), can be calculated using the formula var(Y) = E[Y^2] - (E[Y])^2. Since we have already calculated E[Y], we need to find E[Y^2]. Since Y = X^2, E[Y^2] is equivalent to E[X^4]. However, we do not have enough information about the higher moments of X to directly compute E[X^4]. Therefore, we cannot determine the exact value of var(Y) without additional information.

The system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.

A line process has three processing stages with the characteristics given below:

Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100%

To determine the system capacity and the bottleneck stage and utilization of Stage 3:

The system capacity is calculated by the product of the processing capacity of each stage:

1 x 1 x 2 = 2 units per minute

The bottleneck stage is the stage with the lowest capacity and it is Stage A. Therefore, Stage A has the lowest capacity and determines the system capacity.The utilization of Stage 3 can be calculated as the processing time per unit divided by the available time per unit:

Process time per unit = 1 + 2 + 3 = 6 minutes per unit

Available time per unit = 90% x 100% x 100% = 0.9 x 1 x 1 = 0.9 minutes per unit

The utilization of Stage 3 is, therefore, (6/0.9) x 100% = 666.67%.

However, utilization cannot be greater than 100%, so the actual utilization of Stage 3 is 100%.

Hence, the system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.

The space cost you $833.33. per MONTH

To calculate the monthly cost, we first need to determine the annual cost of the space.

Given that the cost is $10 per square foot per year, we know, there are 12 months in an year and the space is 1,000 square feet, the annual cost of the space would be:

Annual cost = the space  * cost

Annual cost = 1,000 square feet * $10/square foot = $10,000

To convert this to monthly cost, we divide the annual cost by 12 (the number of months in a year):

Monthly cost = $10,000 / 12 = $833.33

The area of the quadrilateral B-H-G-E is 7

Step-by-step explanation:

The area of the parallelogram = 60  

It can be shown that ΔG-D-F = 3/10 × Area of the parallelogram S = 3/10×S

Because the diagonal B-D shares A-F into the ratio 1:2, the ΔH-D-A = 2/3×ΔD-B_A  where ΔD-B_A = 1/2·S, therefore, ΔD-B_A = 2/3×1/2×S = 1/3×S

ΔB-F-H is similar to ΔD-B_A scaled to 1/2,

Therefore;

The area of ΔB-F-H = 1/4×Area of ΔD-B_A = 1/4×1/3×S = 1/12×S,

ΔF-C-D = 1/4×S

ΔE-A-D = 1/4×S

The area of the quadrilateral B_H_G_E found as follows;

Area B_H_G_E  = S - (ΔF-C-D + ΔG-D-F +ΔE-A-D +ΔB-F-H)

Area B_H_G_E  = S - (1/4×S + 1/10×S +1/4×S +1/12×S) = S - 53/60×S = 7/60×S

Whereby we are given that the area, S of the parallelogram AB-CD = 60 we have;

Area B_H G_E  = 7/60×60 = 7

Solving a system of equations we can see that each pair of pants costs €82.94 and each coat costs €26.37

Let's define the variables:

x = cost of a pant

y = cost of a coat.

First, we know that:

3x + 2y = 245

And then there are discounts of 20% and 5%, and the cost of one of each is 100.75, then:

0.8x + 0.95y = 100.75

Then we have a system of equations:

3x + 2y = 245

0.8x + 0.95y = 100.75

We can isolate x on the second equation to get:

x = (100.75 - 0.96y)/0.8

x = 125.9 - 1.2y

Replace that in the other equation:

3*(125.9 - 1.2y) + 2y = 245

Solving for y:

3*125.9 - 3*1.2y + 2y = 245

y*(2 - 3*1.2) = 245 - 3*125.9

y = (245 - 3*125.9)/(2 - 3*1.2)

y = 82.94

Then the value of x is:

x = 125.9 - 1.2*82.94

x = 26.37
