Kim and jay leave at the same time to travel 25 miles to the beach. Kim drives 9 miles in 12 minutes. Jay drives 10 miles in 15
Katen [24]
23. Kim and Jay leave at the same time to travel 25 miles going to the beach. Kim drives 9 miles in 12 minutes Jay drives 10 miles in 15 minutes. Question: who will arrive first? Unit rate of Kim => 9 miles in 12 minutes => 0.75 miles / minutes => 25 / 0.75 It will take 33.33 minutes for Kim to arrive Unit rate of Jay 10 miles in 15 minutes. => 10 miles /15 minutes => 0.67 miles /minute => 25 / 0.67 It will take Jay 37.31 minutes to arrive at the beach. SO Kim will arrive first

Determine which of the indicated column vectors are eigenvectors of the given matrix
gladu [14]
]Eigenvectors are found by the equation (A-\lambda I) \vec{v} = 0$ implying that \det(A-\lambda I) = 0. We then can write:

A-\lambda I = \left [ \begin{array}{cc} 4-\lambda & 2 \\ 5 & 1-\lambda \end{array}\right ] 

And:

\det(A-\lambda I) = (4-\lambda)(1-\lambda) - 10 = 0 

Gives us the characteristic polynomial:

\lambda^2 - 5 \lambda -6 = 0 \implies \lambda_1 = -1, \lambda_2 = 6

So, solving for each eigenvector subspace:

\left [ \begin{array}{cc} 4 & 2 \\ 5 & 1 \end{array} \right ] \left [ \begin{array}{c} x \\ y \end{array} \right ] = \left [ \begin{array}{c} -x \\ -y \end{array} \right ]

Gives us the system of equations:

4x + 2y = -x \newline 5x + y = - y 

Producing the subspace along the line y = -\frac{5}{2} x

We can see then that 3 is the answer.

Bogdan [553]

Answer:

  • See below

Step-by-step explanation:

<u>Multiply and simplify:</u>

  • (x - 1)(x + 2)(x + 3) =
  • (x² + 2x - x -2)(x + 3) =
  • (x² + x - 2)(x + 3) =
  • x³ + 3x² + x² + 3x - 2x - 6 =
  • x³ + 4x² + x - 6

<u>From the final polynomial we can see that:</u>

  • a = 1, b = 4, c = 1 and d = - 6

So all the coefficients are positive but the constant d is negative
