That would be the first and the last functions.
Any permutation where the number after the P is 0 will be equal to 1
The answer is 1
is just a notation way to say, "the nth term will be found by multiplying 2 times the term right before"
so, if you want to find the 27th term, just see what the 26th term is, 2 * "26th term value" and that's the 27th term
simply means, the first term in the geometric sequence
is a geometric sequnce, because is "multiplying something" to get to the next term, if it were adding something, it'd be an arithmetic sequence
so, we know the first term is 4, and the multiplier or "common ratio" is 2
is given in the
part
thus
Answer:
Equations:
--- Hot dog
--- Pretzel
Step-by-step explanation:
Represent hot dogs with H and Pretzels with P.
For Tina:
For Doug:
Solving for the price of both items:
We have:
--- (1)
--- (2)
Multiply (2) by 2
2 * ()
-------------------
--- (3)
Subtract (3) from (1)
----------------------
Solve for P
Substitute 1.25 for P in (2)
Collect Like Terms
Solve for H
