Answer:
Recursive form of sequence is given by f(n) = f(n-1) - 3
Step-by-step explanation:
The explicit form of sequence is given as
f(n) = −3n + 2
So nth term is given by
f(n) = −3n + 2
(n-1)th term is given by
f(n-1) = −3(n-1) + 2
We have
f(n) - f(n-1) = −3n + 2 - (−3(n-1) + 2)
f(n) - f(n-1) = −3n + 2 +3(n-1) - 2
f(n) - f(n-1) = −3n + 2 +3n -3 - 2
f(n) - f(n-1) = -3
f(n) = f(n-1) - 3
Recursive form of sequence is given by f(n) = f(n-1) - 3
The answer is B.) Y = sec X.
Answer: 2x+5 = 50
Step-by-step explanation:
Given the total length of the piece of wood is 50" long. If the wood is sawed into two pieces, let's say the length of the two wood pieces are 'x'and 'y'.
This means x + y = 50... (1)
If one piece is 5" longer than the other, it can be written as;
y = x+5... (2) (this means wood of length y is 5" longer than that of wood of length x. To write the problem as an equation, we will substitute equation 2 into 1 to have
x + y = 50
x + (x+5) = 50
2x+5 = 50 (The will be the required equation where x is the length of the shorter piece of wood)
Answer: 6 or 20 would be the amount. (if there was only one, then i revise this.)
Step-by-step explanation:
You can't simplify the 30 has no common factors
