Answer:
See proof below.
Step-by-step explanation:
True
For this case we need to use the following theorem "If
are eigenvectors of an nxn matrix A and the associated eigenvalues
are distinct, then
are linearly independent". Now we can proof the statement like this:
Proof
Let A a nxn matrix and we can assume that A has n distinct real eingenvalues let's say 
From definition of eigenvector for each one
needs to have associated an eigenvector
for 
And using the theorem from before , the n eigenvectors
are linearly independent since the
are distinct so then we ensure that A is diagonalizable.
Answer:
the first option is correct
since value of a will be found through division.
Answer:a.100+(hx25)
b.120+(hx20)
c.4 hours
h=hours
Step-by-step explanation:
Okay. When it comes to multiplying decimals, you multiply them just like you would do whole numbers. However, solving them by paper, you would add a decimal point into the answer, depending on how many numbers are behind the decimal point in the numbers being multiplied. In this case, the decimal point will go in front of two numbers, because there are two numbers behind the decimal point in -1.2 and 0.4. Know that the answer will be negative, because there is one negative and one positive number.
Multiply both numbers. -1.2 * 0.4 is -0.48. There. The product is -0.48.

Answer:
(d) 25°
Step-by-step explanation:
Each diagonal represents a transversal between parallel lines. Alternate interior angles are congruent, so ...
∠BDC ≅ ∠DBA = 25°
