Answer:
Step-by-step explanation:
f(x)=25-x^2 and g(x)=x+5
We need to find (f/g)(x)
(f/g)(x) = f(x)/ g(x)
we divide f(x) by g(x) and then we simplify
WE factor 25-x^2
25-x^2 = 5^2 - x^2 = (5-x)(5+x)
5+x or x+5 are same , so we cancel out x+5
What is the expression for the below sequence (use n) -3,-6,-9,-12
1 answer:
Answer:
= - 3n
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 6 - (- 3) = - 9 - (- 6) = - 12 - (- 9) = - 3
This indicate the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = - 3 , thus
= - 3 - 3(n - 1) = - 3 - 3n + 3 = - 3n
The n th term is - 3n
