I'm not going to explain it too much, because that's all you ever see on these forums.
slope = rate of change
The bigger the number by x, the greater the rate of change.
This is my first time actually answering a question, so I really hope that this helped. ;)
Answer:
10
Step-by-step explanation:
geometric mean theorem :
h = sqrt(pq)
p, q being the segments on the Hypotenuse of the right-angled triangle.
so, x = sqrt(9×10) = 3×sqrt(10)
Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.
For (B) you just round up. So again $5280 rounds up to $5300.
