There does not exists a rational number t such that  [tex]t^2 = 2[/tex].

Suppose the contrary, that there exists a rational number t such that[tex]t^2 = 2[/tex]. Then t can be written in its lowest terms as t = p/q, where p and q are integers, with q≠ 0. Then squaring both sides gives[tex](p/q)^2 = 2[/tex], so [tex]p^2 = 2q^2[/tex]. Since both [tex]p^2[/tex] and [tex]q^2[/tex] are integers, this implies that 2 is a perfect square, which it is not.

In detail, assume t = p/q where p and q are integers and q ≠ 0. Then [tex]t^2 = 2[/tex] can be written as [tex]t^2 = 2[/tex].. This implies [tex]p^2 = 2q^2[/tex].

The length, in units, of the rectangle is 9 units.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Length = x

Width = x - 8

Area = 9 square units

Now,

The area of the rectangle = length x width

9 = x (x - 8)

9 = x² - 8x

x² - 8x - 9 = 0

Solve for x.

x² - 8x - 9 = 0

x² - (9 - 1)x - 9 = 0

x² - 9x + x - 9 = 0

x(x - 9) + 1(x - 9) = 0

(x - 9) (x + 1) = 0

x - 9 =0 and x + 1 = 0

x = 9 and x = -1 (rejected)

Now,

Length = 9

Width = 9 - 8 = 1

Thus,

Length is 9.

The puzzle method takes in an int x and returns an int based on its parameter x. If x is greater than 20, then the method will return x - 10.

The puzzle method takes in an int x and returns an int based on its parameter x. The formula for this method is as follows:

If x > 20, then the method will return x - 10.

For example, if x is 30, then the method will return 30 - 10 = 20.

The calculation for this method can be seen in the following example.

If x is 30, the calculation would be as follows:

30 > 20

30 - 10 = 20

Therefore, the method will return 20.

In conclusion, the puzzle method takes in an int x and returns

Answer:

0.3

Step-by-step explanation:

To solve this, I asked, "If 7 divided by 21 is 3, then 7 divided by 22 would have little to no difference in the tenths place, right?" And that question is correct. Answering this question, the decimal place could not be greater than 5, because 7/22 is the formula for another, more accurate, albeit shorter version of pi, but backwards. 7/22 is 0.31, and 0.31's tenths place has a 1 in it, so this, according to the laws of rounding, rounds downward. Therefore, the correct answer would be 0.3.

The Marginal Revenue MR(29) 11513 dollars per unit.

The velocity is v(t) = 24t² - 96t - 120.

The velocity equals zero at t = 5.

The acceleration of the particle is a(t) = 48t - 96.

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

Suppose a product's revenue function is given by R(q) = -7q² + 600q,

where R(q) is in dollars and q is units sold.

We have to determine a numeric value for the marginal revenue at 29 units

As per the question we have

R(q) = -7q² + 600q

Substitute the value of q = 29, and we get

R(29) = -7(29)² + 600(29)

R(29) = 11513

Thus, the Marginal Revenue MR(29) 11513 dollars per unit

Let s(t) = 8t³ - 48t² - 120t be the equation of motion for a particle.

To find the velocity, we need to differentiate the equation for the position of the particle, s(t).

v(t) = ds/dt = d/dt (8t³ - 48t² - 120t) = 24t² - 96t - 120

To find the t-values where the velocity is equal to zero, we need to set v(t) equal to zero and solve for t.

0 = 24t² - 96t - 120

This is a quadratic equation, and we can solve for t by factoring the GCF

(t - 5)(t + 1) = 0

(t - 5) = 0 and (t + 1) = 0

t = 5 and t = -1

So the velocity equals zero at t = 5

To find the acceleration, we need to differentiate the velocity function, v(t).

a(t) = dv/dt = d/dt (24t² - 96t - 120) = 48t - 96

So the acceleration of the particle is a(t) = 48t - 96.

The entropy of X (number of defective chips) in bits is a measure of uncertainty about the value of X.

The entropy of a random variable represents the amount of uncertainty or randomness associated with the outcome of the variable. To calculate the entropy of a discrete random variable, we need to determine the probability distribution function and use the formula:

H(X) = -Σ P(X=x) log2(P(X=x))

In this case, the random variable X represents the number of defective chips in 5 randomly chosen chips from a box of 50, with 3 defective chips. The possible outcomes are 0, 1, 2, 3, and 4, with probabilities:

P(X=0) = (47/50)^5

P(X=1) = (5 * (3/50) * (47/50)^4)

P(X=2) = (10 * (3/50)^2 * (47/50)^3) / 2!

P(X=3) = (5 * (3/50)^3 * (47/50)^2) / 3!

P(X=4) = (3/50)^4 / 4!

x is not an integer, and is instead an irrational number that lies between -1/6 and 1/9.

We can solve this problem using the law of sines. The law of sines states that for a triangle, the ratio of the side opposite an angle to the sine of that angle is equal for all three angles. Therefore, we can solve for x by setting up two equations, one for angle W and one for angle X.

For angle W, the equation is:

18x - 2 = sin-1(VX/WY)

For angle X, the equation is:

12x + 2 = sin-1(VW/YX)

Since we know the ratio of the sides of the triangle, we can solve for x by substituting these values into the equations.

For angle W, we get:

18x - 2 = sin-1(VX/WY)

18x - 2 = sin-1(2/2)

18x - 2 = 0

18x = 2

x = 1/9

For angle X, we get:

12x + 2 = sin-1(VW/YX)

12x + 2 = sin-1(2/2)

12x + 2 = 0

12x = -2

x = -1/6

K * K > N, because if the square of K is greater than N, it is not possible to add K distinct odd integers to get N.

If you square an integer (multiply it by itself), the result will always be an even number. If K is an odd number, then K * K will be an odd number plus one, which makes it even.

For example, if K = 3, then K * K = 9, which is an even number. If we take the square root of 9, we get 3, which is K. This means that the square of K will always be greater than K itself.

Now, if we want to add K distinct odd integers to get N, then N must be greater than K * K. This is because the sum of K odd numbers will always be less than K * K, and we need N to be greater than this sum.

Therefore, if K * K > N, it means that it is not possible to add K distinct odd integers to get N, because N is smaller than K * K, and the sum of K odd numbers will be smaller than N.

The area of the walkway around the garden as the sum of two terms is,  2(w + l) = 2(8x + 21).

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Let's call the width of the garden w and the length of the garden l.

Then, the area of the garden is,

wl = 6(2.5x + 1.5).

The combined area of the garden and the walkway is 7.5(4x + 5).

We can write this as wl + 2(w + l), since the walkway goes around the perimeter of the garden.

Equating the two expressions for the combined area, we have:

wl + 2(w + l) = 7.5(4x + 5)

Substituting wl = 6(2.5x + 1.5), we get:

6(2.5x + 1.5) + 2(w + l) = 7.5(4x + 5)

Expanding both sides, we get:

15x + 9 + 2w + 2l = 30x + 37.5

Solving for w + l, we get:

w + l = 15x + 28.5 - 7.5 = 8x + 21

So the area of the walkway around the garden can be expressed as 2(w + l) = 2(8x + 21).
