What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be:
Ok, so there are 2 men per 7 women so we can just scale up so there are 4 men per 14 women and then 6 men per 21 women but there are 36 performers so we have to keep going till it equals 36 people so 8 men per 28 women = 36 people so 8 men!

Step-by-step explanation:
2.73x8=21.84
Answer:
a) 34
b) 30
Step-by-step explanation:
so the nth term is just the position on the term, so if u want to find the 5th term you just have to substitute 5 in for n and solve!
a) 6n + 4
= 6(5) + 4
= 30 + 4
= 34 --> the 5th term for a sequence defined by 6n+4 is 34
b) n^2 + 5
= (5)^2 + 5
= 25 + 5
= 30 --> the 5th term for a sequence defined by n^2 + 5 is 30
hope this helps!
Answer:
sn = d/2·n^2 + (a - d/2)·n
sn = (-4)/2·n^2 + (19 - (-4)/2)·n = -441
- 2·n^2 + 21·n = -441
- 2·n^2 + 21·n + 441 = 0
n^2 - 21/2·n - 441/2 = 0
use pq-Formula
n = -10.5 ∨ n = 21
only n = 21 makes sense. So n = 21 is the correct answer.
