Answer:
D
Step-by-step explanation:
The answer is d, because a represents adults, and c represent children. It's $45 per adult, so $45a, and $30 per child, so $30c. a+c is equal to 10, because that's how many tickets were purchased. $45a+$30c=345, because $345 is the total amount spent on tickets.

Answer: 5
Step-by-step explanation:
A = xˆ(2−1)+yˆ(−1−(−1))+zˆ(0−(−3)) = xˆ +zˆ3,
|A| =
√
1+9 = 3.16,
aˆ =
A
|A|
=
xˆ +zˆ3
3.16
= xˆ 0.32+zˆ 0.95.
