the correct answer is y = -1/2x + 6

Step-by-step explanation:

The value of the exponential equation is A = 5/3

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = [ 2²⁰¹⁴ + 2²⁰¹² ] / [ 2²⁰¹⁴ - 2²⁰¹² ]   be equation (1)

On simplifying the equation , we get

Taking the common factor as 2²⁰¹² , we get

A = 2²⁰¹² [ 2² + 1 ] / 2²⁰¹² [ 2² - 1 ]

On further simplification , we get

A = ( 2² + 1 ) / ( 2² - 1 )

A = ( 4 + 1 ) / ( 4 - 1 )

A = 5/3

Therefore , the value of A is 5/3

Hence , the equation is A = 5/3

27. y = 5/2x - 1/2

28. y = x + 3

29. y = -x + 2

30. y = -1/4x + 9/4

The equation of a line is y = mx + b, in slope-intercept form, where:

m = slope = rise/run = change in y / change in x

b = y-intercept or the point where the graph intercepts the y-axis.

22. Slope (m) = rise/run = -1/2

Substitute m = -1/2 and b = 3 into the equation, y = mx + b:

y = -1/2x + 3.

23. Slope (m) = rise/run = 4/2 = 2

y-intercept (b) = -3

Substitute m = 2 and b = -3 into the equation, y = mx + b:

y = 2x - 3.

24. Slope (m) = rise/run = -2/2 = -1

y-intercept (b) = 0

Substitute m = -1 and b = 0 into the equation, y = mx + b:

y = -x + 0

y = -x

25. Slope (m) = rise/run = -2/1 = -2

P-value of a hypothesis test is an important measure of the strength of evidence against the null hypothesis and helps us make informed decisions about rejecting or failing to reject the null hypothesis.

A hypothesis test is a statistical method used to test the validity of an assumption or a hypothesis about a population based on a sample data.

The correct answer is b. The P-value of a hypothesis test is the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true.

In hypothesis testing, we start with a null hypothesis, which is usually denoted as H_0, that represents the status quo or the default assumption. The alternative hypothesis, denoted as H_a, represents the opposite of the null hypothesis.

The P-value is the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true. A low P-value indicates that the sample data provides strong evidence against the null hypothesis, and we reject the null hypothesis.

A high P-value indicates that the sample data does not provide strong evidence against the null hypothesis, and we fail to reject the null hypothesis.

In mathematical terms, the P-value is calculated as the probability of observing a test statistic Z that is more extreme than the one actually obtained, assuming the null hypothesis is true.

Answer:

Step-by-step explanation:

You want to know the work done to empty a half-full spherical tank of radius 3 m containing liquid of density 900 kg/m³ through a 2 m spout at the top of the tank.

The mass of the liquid is the product of its volume and its density. The volume of the hemisphere is ...

  V = 2/3πr³ = 2/3π(3³) = 18π . . . . . . cubic meters

Then the mass of the liquid is ...

  m = ρV = (900 kg/m³)(18π m³) = 16200π kg

The centroid of the liquid is 3/8r below the center of the tank. The mass of liquid must be moved from that location to a point 2 m above the top of the tank. The total height the liquid must be moved is ...

  3/8(3 m) + 3m + 2m = 6.125 m

The work done to lift the liquid is ...

  W = Fd = (m·g)d = (16200π kg)(9.8 m/s²)(6.125 m) = 972405π J

  W ≈ 3,054,900.4 J ≈ 3.0549 MJ

The work required is about 3.0549 megajoules.

__

Additional comment

We could find the incremental work to move a layer of liquid dy thick to the necessary height, then integrate over the depth of liquid. It is much easier to look up the centroid location for a hemisphere, and use that in the calculation.

We have used "m" to represent both mass and meters. We trust you can determine which is which from the context.

The requried difference between the perimeters of the two gardens would be, 12x + 20 - 4s.

Perimeter is the measure of the figure on its circumference.

Here,
Let's assume that Shawn's garden is also a square with side lengths. Therefore, the perimeter of Shawn's garden would be 4s.
The perimeter of Charlie's garden would be 4(3x + 5), which simplifies to 12x + 20.

The difference between the perimeters of the two gardens would be,

12x + 20 - 4s

We can't simplify this expression any further without knowing the value of s.

Therefore, we can conclude that the difference between the perimeters of the two gardens depends on the side length of Shawn's garden.

Using division, we know that Leo replaces 6 new strings from 3 guitars which are a total of 18 strings.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

On a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.

When no more full chunks of the size of the second number can be allocated during the computation of the quotient, the division with a remainder or Euclidean division of two natural numbers yields an integer quotient, which is the number of times the second number is entirely contained in the first number, and a remainder, which is the portion of the first number that remains.

So, we know that:

6 new strings are put on each guitar.

He uses 18 strings.

Then, the number of guitars:

⇒ 18/6 = 3

the ratio of yellow : blue = 2 : 3 = 2x : 3x ( x is a multiplier )

after buying 27 more blue buttons

2x : 3x + 27 = 4 : 9

expressing the ratios in fractional form

[tex]\frac{2x}{3x+27}[/tex] = [tex]\frac{4}{9}[/tex] ( cross- multiply )

18x = 4(3x + 27)

18x = 12x + 108 ( subtract 12x from both sides )

6x = 108 ( divide both sides by 6 )

x = 18

number of buttons at first = 2x + 3x = 5x = 5 × 18 = 90
