Check the true statements below:

a. the orthogonal projection of yy onto vv is the same as the orthogonal projection of yy onto cvcv whenever c≠0c≠0.

b. if the columns of an m×nm×n matrix aa are orthonormal, then the linear mapping x→axx→ax preserves lengths.

c. if a set s={}s={} has the property that ui⋅uj=0ui⋅uj=0 whenever i≠ji≠j, then ss is an orthonormal set.

d. an orthogonal matrix is invertible.

e. not every orthogonal set in rnrn is a linearly independent set.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

i think it might be a but you might want a second opinion

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.  

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
