500,000,000 and 2,000,000
10 exponent 8 is 100000000 because it has 8 0s
multiply that by 5 to get 500,000,000
10 exponent 6 is 1000000 because it has 6 0s
multiply by 2 to get 2,000,000
Answer:
no it is not biased because it is randomly selected although in alphabetical order.
Step-by-step explanation:
]Eigenvectors are found by the equation
![(A-\lambda I) \vec{v} = 0$](https://tex.z-dn.net/?f=%28A-%5Clambda%20I%29%20%5Cvec%7Bv%7D%20%3D%200%24)
implying that
![\det(A-\lambda I) = 0](https://tex.z-dn.net/?f=%5Cdet%28A-%5Clambda%20I%29%20%3D%200)
. We then can write:
And:
Gives us the characteristic polynomial:
![\lambda^2 - 5 \lambda -6 = 0 \implies \lambda_1 = -1, \lambda_2 = 6](https://tex.z-dn.net/?f=%20%5Clambda%5E2%20-%205%20%5Clambda%20-6%20%3D%200%20%5Cimplies%20%5Clambda_1%20%3D%20-1%2C%20%5Clambda_2%20%3D%206)
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 ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%20%5Cbegin%7Barray%7D%7Bcc%7D%204%20%26%202%20%5C%5C%205%20%26%201%20%5Cend%7Barray%7D%20%5Cright%20%5D%20%5Cleft%20%5B%20%5Cbegin%7Barray%7D%7Bc%7D%20x%20%5C%5C%20y%20%5Cend%7Barray%7D%20%5Cright%20%5D%20%3D%20%5Cleft%20%5B%20%5Cbegin%7Barray%7D%7Bc%7D%20-x%20%5C%5C%20-y%20%5Cend%7Barray%7D%20%5Cright%20%5D%20)
Gives us the system of equations:
Producing the subspace along the line
![y = -\frac{5}{2} x](https://tex.z-dn.net/?f=%20y%20%3D%20-%5Cfrac%7B5%7D%7B2%7D%20x%20)
We can see then that 3 is the answer.
Answer: 2.4 miles per hour
Step-by-step explanation: just do 7.2/3=2.4
or another way you could do this is do 2.4 x 3=7.2
