Answer:

Step-by-step explanation:
The vertex form of a parabola f(x) = ax² + bx + c:

(h, k) - vertex

We have the equation:

Finally:

You first work out the mean then for each number subtract the mean and square the result then work out the mean of those squared differences and take the square rot of that and you're done :)
The one that has -7 and -13 on the first line.
Itd be the 2nd answer from the top.
Answer:
n = 5
Step-by-step explanation:
100,000 = 10^n
Take the log of both sides
log 100,000 = log 10^n
log 100,000 = n * log 10
Dividing both sides by log 10
log 100,000 / log 10 = n * log 10 / log 10
n = log 100,000 / log 10
= 5 / 1
n = 5
