The eigenvalues of the given matrix are 4, 2, 0, and 0, with corresponding eigenvectors given by [1, sin(πn/5), sin(2πn/5), sin(3πn/5)] for eigenvalue 4, [1, sin(πn/5), sin(2πn/5), sin(3πn/5)] for eigenvalue 2, [0, cos(πn/5), cos(2πn/5), cos(3πn/5)] for eigenvalue 0 (n ≠ 0), and [0, 1, -2, 1] and [1, 0, 0, 0] for eigenvalue 0 (n = 0).
To find the eigenvalues and eigenvectors, we start by using the sine transform. Let S be the 4x4 sine matrix, i.e., the entry in the i-th row and j-th column of S is given by sin(πij/5). Then, we can write the given matrix as M = 3I + S + S^T, where I is the 4x4 identity matrix.
Next, we find the eigenvalues of S. Since S is a real symmetric matrix, its eigenvalues are real and its eigenvectors are orthogonal. By inspection, we see that the columns of S are orthogonal and have length 2, so the eigenvalues of S are given by λn = 2(1 - cos(πn/5)) for n = 1, 2, 3.
Now, we can find the eigenvalues of M. Since M = 3I + S + S^T, the eigenvalues of M are given by μn = 3 + λn + λm, where λn and λm are the eigenvalues of S. Thus, we have μ1 = 4, μ2 = 2, and μ3 = μ4 = 0.
To find the eigenvectors of M, we need to solve the equations (M - μnI)x = 0 for each eigenvalue μn. For μ1 = 4, we have (M - 4I)x = (S - 2I)(S^T - 2I)x = 0, which has non-trivial solutions of the form [1, sin(πn/5), sin(2πn/5), sin(3πn/5)] for n = 1, 2, 3, 4.
Similarly, for μ2 = 2, we have solutions of the form [1, sin(πn/5), sin(2πn/5), sin(3πn/5)] for n = 1, 2, 3, 4. For μ3 = 0, we have solutions of the form [0, cos(πn/5), cos(2πn/5), cos(3πn/5)] for n ≠ 0. Finally, for μ4 = 0, we have two linearly independent solutions: [0, 1, -2, 1] and [1, 0, 0, 0].

Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula,
Step-by-step explanation:
= 25 a²- ( 4b²- 28bc +49c²)
=. 25a²- {( 2b)²- 2(2b)(7c)+ (7)²}
= 25a²- { (2b - 7c)²}

In Vicky's rose garden, 2 of the rose bushes are blooming and the other 17 rose bushes are not blooming. What is the ratio of the number of bushes that are blooming to the total number of bushes?
Answer:
2 : 19
Step-by-step explanation:
We know 2 of the bushes are blooming (this is the left number in my answer) but the other 17 are not. Neither of these is the total number of bushes. To find that, we need to add these together to get 2 + 17 = 19.
This means 2 out of 19 rose bushes are blooming.

eliminate the parameter in the equations x=5cos(t) -7 and y=5sin(t)+9. how can the rectangular equation be described?
circle
ellipse
parabola
hyperbola
Answer:
the answer is A
Step-by-step explanation:
The parameters represent a circle with a radius of 5 units, centered at (-7,9) and the equation of the circle is (x + 7)² + (y - 9)² = 5².
Deducing the figure from the parameters:The given equations are:
x = 5cos(t) - 7, and
y = 5sin(t) + 9
if we rearrange the above equations we get:
(x + 7) = 5cos(t), and
(y - 9) = 5sin(t)
Taking square of both equation we get:
(x + 7)² = 25cos²(t), and
(y - 9)² = 25sin²(t)
Now, adding the equations we get:
(x + 7)² + (y - 9)² = 25cos²(t) + 25sin²(t)
(x + 7)² + (y - 9)² = 25
(x + 7)² + (y - 9)² = 5²
This is an equation of a circle with a radius of 5 units and the center at (-7,9)
since, the equation of a circle with radius R units and centered at (a,b) is given by:
(x -a)² + (y - b)² = R²

Answer:
it cannot be proven
Explanation:
You cannot prove what isn't true.
We know you know how to use parentheses, so we take the left-side expression at face value. The left-side and right-side functions are different, so cannot be proved to be the same, except at specific angles.

Kyle is correct, the quadrilaterals are not similarStep-by-step explanation:
Measure the corresponding sides and verify if the ratios are same or not.
Corresponding sides:
AB and LM, BC and MN, CD and NO, AD and LOThe measures, using coorinates and the distance formula:
AB = √(2-1)² + (4-3)² = √2LM = √(16-14)² + (4-6)² = √8 = 2√2BC = √(5-2)²+(5-4)² = √10MN = √(23-16)²+(2-4)² = √53We can see the ratios of the two pairs are not same:
AB/LM = 1/2BC/MN = √10/531/2 ≠ √10/53We can state that Kyle is correct
a=10t+0 find the y intercept
Answer:
0
Step-by-step explanation:
The y intercept is the constant in this equation, as in the only number unaccompanied or affected by a variable. In this case, assuming y is a and x is t, the y intercept is 0. You can test this by plugging in y=10x+0 into a graphing calculator. The y intercept is where x equals 0, and so if you plug in 0 for x, the result (in this case 0) is the y intercept.
