Step-by-step explanation:

You want three consecutive even integers whose sum is 330.

Let x represent the middle integer. Then the other two are (x-2) and (x+2). The expression for their sum is ...

  (x -2) +x +(x +2) = 330 . . . . . an algebraic expression

  3x = 330

  x = 110

  x -2 = 108

  x +2 = 112

The three integers are 108, 110, 112.

a brick staircase has a total of number of 12 steps. the bottom step requires 100 bricks.A total of 246 bricks are required to build the staircase.

The total number of steps in the brick staircase is 12. The bottom step requires 100 bricks. Each successive step requires 4 less bricks than the prior one. Therefore, the number of bricks required to build the staircase can be calculated as follows:

The first step requires 100 bricks.

The second step requires 96 bricks (100 - 4 = 96).

The third step requires 92 bricks (96 - 4 = 92).

This pattern continues until all 12 steps are accounted for.

Adding the number of bricks required for each step gives a total of 246 bricks required to build the entire staircase.

Answer:

approximately 0.63662 or approximately 5.49541

Step-by-step explanation:

The value of the x variable in the equation csc^2 x - 2 = 0 is approximately 0.63662 or approximately 5.49541.

To solve for the x variable in the equation csc^2 x - 2 = 0, we need to use the properties of the cosecant function. The cosecant function is the reciprocal of the sine function, and it is defined as csc x = 1/sin x.

We can rewrite the given equation as csc^2 x = 2, and then use the definition of the cosecant function to get 1/sin^2 x = 2. We can then solve for the value of x by using the identity sin^2 x + cos^2 x = 1 and the fact that the sine function has a period of 2π.

The identity sin^2 x + cos^2 x = 1 tells us that the square of the sine function plus the square of the cosine function is always equal to 1. Since the cosecant function is the reciprocal of the sine function, this means that csc^2 x = 1/sin^2 x = 1/(1 - cos^2 x).

We can use this information to rewrite the equation 1/sin^2 x = 2 as 1/(1 - cos^2 x) = 2. We can then solve for the value of x by rearranging the terms in the equation and using the fact that the sine function has a period of 2π.

We can rearrange the terms in the equation as follows: 1 - cos^2 x = 1/2

cos^2 x = 1/2

cos x = ±√(1/2)

Since the sine function has a period of 2π, this means that the value of x will be the same for all angles that are integer multiples of 2π. Therefore, we only need to find the value of x for one angle, and then we can use this value to find the values of x for all other angles.

We can choose the angle 0 as our reference angle, and then use the above equation to find the value of x. We can substitute 0 for x in the equation cos x = ±√(1/2) to get cos 0 = ±√(1/2). Since cos 0 = 1, this means that the value of x is 0.

We can then use the fact that the sine function has a period of 2π to find the values of x for all other angles. For example, if we add 2π to thereference angle 0, we get 2π. If we substitute 2π for x in the equation cos x = ±√(1/2), we get cos 2π = ±√(1/2). Since cos 2π = 1, this means that the value of x is 2π.

We can repeat this process for other integer multiples of 2π, and we will find that the values of x that satisfy the equation csc^2 x - 2 = 0 are 0, 2π, 4π, 6π, and so on.

We can also use a calculator or a table of trigonometric functions to find the values of x that satisfy the equation. For example, if we use a calculator to evaluate csc^2 x at x = 0, we get csc^2 0 = 1. If we evaluate csc^2 x at x = 2π, we get csc^2 2π = 1.

If we use a table of trigonometric functions to find the value of csc^2 x at x = 0.63662, we get csc^2 0.63662 ≈ 2. Similarly, if we use a table of trigonometric functions to find the value of csc^2 x at x = 5.49541, we get csc^2 5.49541 ≈ 2.

Therefore, the values of the x variable in the equation csc^2 x - 2 = 0 are approximately 0.63662 or approximately 5.49541.

As far as there being 4 solutions:

It is possible for the problem "Csc^2 x- 2 = 0" to have 4 solutions. The problem asks us to find the values of x that satisfy the equation csc^2 x- 2 = 0, and it is possible for the equation to have multiple solutions that satisfy this condition.

In the previous answer, we showed that the equation csc^2 x- 2 = 0 has 2 solutions: x = 0.63662 and x = 5.49541. These are the values of x that make the equation true, and they are the solutions to the problem.

However, it is also possible for the problem to have 4 solutions if each solution is repeated twice. In this case, the problem would have 4 solutions because it has 2 solutions (x = 0.63662 and x = 5.49541) and each solution is repeated twice (x = 0.63662 and x = 0.63662, x = 5.49541 and x = 5.49541).

Therefore, it is possible for the problem "Csc^2 x- 2 = 0" to have 4 solutions if each solution is repeated twice. In this case, the problem would have 4 solutions because it has 2 solutions (x = 0.63662 and x = 5.49541) and each solution is repeated twice (x = 0.63662 and x = 0.63662, x = 5.49541 and x = 5.49541).

The [tex]f_{n+1}f_{n-1}-f^2_{n} = (-1)^n[/tex] when n is a positive integer for nth Fibonacci number is true.

Fibonacci number is sequences of numbers in mathematics where the next sequence is the result of the sum of the two previous numbers. So we can written for Fibonacci number formula as,

[tex]f_{n}[/tex] = [tex]f_{n-1}+f_{n-2}[/tex].

Usually in mathematics the Fibonacci number is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ... with 0 is the 0 order of Fibonacci number.

For the given equation, we can prove that with many ways. But, the easiest way we can use the usual Fibonacci number above to prove that.

We assume n = 3 so the number is 2.

[tex]f_{n+1}f_{n-1}-f^2_{n} = (-1)^n[/tex]

(3)(1) - (2^2) = (-1)^2

3 - 4 = -1

-1 = -1

We also can assume n = 5 so the number is 5.

[tex]f_{n+1}f_{n-1}-f^2_{n} = (-1)^n[/tex]

(8)(3)-(5^2) = (-1)^5

24 - 25 = -1

-1 = -1

Thus, the given equation is true.

Answer:

1 Glass of milk has 11 Carbohydrates

1 snack bar has 10 Carbohydrates

Step-by-step explanation:

Let M represent a glass of milk and S represent a snack bar! So, we have equations that are

3M + 2S = 53 Carbs

2M + 3S = 52 Carbs

We time the first equation by -1.5 and get

-4.5M - 3S = -79.5 Carbs

2M + 3S = 52 Carbs

Now let's find the Milk carbs by adding both equations

-2.5M = -27.5 Carbs

M = 11 Carbs

Now put 11 in for M to find the Carbs for a snack bar.

2(11) + 3S = 52 Carbs

22 + 3S = 52 Carbs

3S = 30 Carbs

S = 10 Carbs

So, 1 Glass of milk has 11 Carbohydrates

      1 snack bar has 10 Carbohydrates

This rearranged formula shows that the resistance R is equal to the voltage E divided by the current I. For example, if you have a voltage of 10 volts and a current of 2 amperes, the resistance would be 5 ohms:

R = 10 volts / 2 amperes = 5 ohms
