Well since all of them are the same we have to look for one common number and given that they are all acute angles id say its about 30 or 50

Last month, a car dealership sold 184 new cars. To determine customer satisfaction, the sales manager asked all of these newcar

cricket20 [7]

126 car owners were not completely satisfied with their purchase.

If we add 32 and 24, that would give us 56. This problem represents the total amount of people who gave a review.

Then we would take 184, and subtract it by 56. That would give us 126. The 56 represents the amount of people who didnt exactly give a negative survey result, we still dont know how many gave a negative result, therefore we subtract the amount of people who has already submitted a complete and "positive" survey, to the overall amount of people that has bought a car.

For which value of b would x^2 + bx - 24 be prime? a. 3 b. 5 c. 10 d. 23

Lapatulllka [165]

Answer:

Step-by-step explanation:

24 + (-1) = 23, 12 + (-2) = 10, 8 + (-3) = and 6 + (- 4) = 2, none of the sums are equal to 3, therefore b = 3 would give a prime quadratic. The correct answer is then A. 3

A = 4 0 0 1 3 0 −2 3 −1 Find the characteristic polynomial for the matrix A. (Write your answer in terms of λ.) Find the real ei

Illusion [34]

Answer:

Step-by-step explanation:

We are given the matrix

$A = \left[\begin{matrix}4&0&0 \\ 1&3&0 \\-2&3&-1 \end{matrix}\right]$

a) To find the characteristic polynomial we calculate $\text{det}(A-\lambda I)=0$ where I is the identity matrix of appropiate size. in this case the characteristic polynomial is

$\left|\begin{matrix}4-\lambda&0&0 \\ 1&3-\lambda&0 \\-2&3&-1-\lambda \end{matrix}\right|=0$

Since this matrix is upper triangular, its determinant is the multiplication of the diagonal entries, that is

$(4-\lambda)(3-\lambda)(-1-\lambda)=(\lambda-4)(\lambda-3)(\lambda+1)=0$

which is the characteristic polynomial of A.

b) To find the eigenvalues of A, we find the roots of the characteristic polynomials. In this case they are $\lambda=4,3,-1$

c) To find the base associated to the eigenvalue lambda, we replace the value of lambda in the expression $A-\lambda I$ and solve the system $(A-\lambda I)x =0$ by finding a base for its solution space. We will show this process for one value of lambda and give the solution for the other cases.

Consider $\lambda = 4$ . We get the matrix

$\left[\begin{matrix}0&0&0 \\ 1&-1&0 \\-2&3&-5 \end{matrix}\right]$

The second line gives us the equation x-y =0. Which implies that x=y. The third line gives us the equation -2x+3y-5z=0. Since x=y, it becomes y-5z =0. This implies that y = 5z. So, combining this equations, the solution of the homogeneus system is given by

$(x,y,z) = (5z,5z,z) = z(5,5,1)$

So, the base for this eigenspace is the vector (5,5,1).

If $\lambda = 3$ then the base is (0,4,3) and if $\lambda = -1$ then the base is (0,0,1)
