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:
The answer is the option D
and 
Step-by-step explanation:
we have
we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
see the attached figure
The solution are the points 
and 
therefore
The solution of the equation 
are
so
For 
For 
therefore
and because the intersection points are common points for both graphs
Cos (Ф) = 0.9123
To calculate Ф, we have to find the arcos (0.9123) ≈ cos⁻¹ (0.9123)
cos⁻¹(0.9123) = Ф
cos⁻¹ (0.9123) = 24°.175
Ф = 24°.175
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
Answer: slope: 180 y intercept: -360
