Interesting question. Good to know for computer science.
Suppose you have a function like
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1
a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3
an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3
a3 = 7
a4 = a3 + 3
a4 = 7 + 3
a4 = 10
a5 = a4+ 3
a5 = 10 + 3
a5 = 13
I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16
a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.
So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.
Answer: 17 Yards Long
Step-by-step explanation: If the run is 1 section wide at each end, that would leave 34 for each 1 yard section for the lengths needed. So, 34 / 2 = 17 sections in length. You could also do it like this 17 + 1 + 17 + 1 = 36 for a simpler calculation.
Answer: x=3 ==> 1st option
Step-by-step explanation:
FH=FG+GH
18=4x+2x
6x=18
x=3 ==> 1st option
Answer:
An "n" degree polynomial can have up to (n - 1) turning points. So this function will have 3 turning points.
Step-by-step explanation:
Look at the first 6x^4. "n" in this is the exponent which is 4.
4 - 1 is 3. So there will be 3 turning points.
The "n" value is also even degree. So both ends of the function will end in the same direction (High to High or Low to Low depending on if the function has a negative or positive at the start)
