Answer:
Step-by-step explanation:
The explicit formula for the n-th term of an arithmetic sequence is ...
an = a1 + d(n -1)
where a1 is the first term and d is the common difference.
The sequence of seat counts has a1=5 and d=10, so the explicit formula is ...
an = 5 +10(n -1)
___
The 7th term is ...
a7 = 5 +10(7 -1) = 65
96°.
Since sides AB and AC ane equal, that means that angle B is equal to angle C. The measurement of all the angles of a triangle always equals 180°, so if you add angles B and C, you should get 84° and then you should be able to find angle A. Subtract 84° from 180° and you should get 96°.

Answer:
The answer is 17
Step-by-step explanation:
To find the answer, we first have to put the values in for a and b.
√225 + ║2 - 3(1/3)(4)║
√225 + ║2 - 4║
√225 + ║-2║
√225 + 2
15 + 2
17
