Answer:
Thats false
Step-by-step explanation:
When you multiply by a power your basically multiplying that number b itself 10x except for 1
Answer:
-157.87
Step-by-step explanation:
1) the rules are:
and
![log_ab^c=c*log_ab.](https://tex.z-dn.net/?f=log_ab%5Ec%3Dc%2Alog_ab.)
2) according to the rules above:
![log_7(yz^8)=log_7y+8log_7z=-6.19-8*18.96=-157.87.](https://tex.z-dn.net/?f=log_7%28yz%5E8%29%3Dlog_7y%2B8log_7z%3D-6.19-8%2A18.96%3D-157.87.)
Answer:
The following are the answer:
In option a "No".
In option b "Yes".
Step-by-step explanation:
In choice a:
Ax = 0 has no nontrivial solution. A would be the three-pivot matrix, it may assume, that the function has no free variable, and only if the function has had at least one free factor are their nontrivial formulas for the equations of the form Ax=0.
It implies that since A is a 3x3 matrix, has no free variables so that it has no non-trivial choices, and Ax = 0.
In choice b:
we assume that every potential has at least one solution that is Ax=b
. If A does have a three-pivot matrix, It will be a pivot element for each row and column, and for each possible b∈ R³, Ax = b has at least one solution.
Answer:
11. AW║BY
12. DX║YZ
13. AW║YZ
14. AW║DZ
Step-by-step explanation:
11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.
12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.
13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.
14. Lines perpendicular to the same line are parallel.
