Answer:
C 7ft/yr
Step-by-step explanation:
The given points are not all on the same line, so the average will vary depending on the interval of interest.
Over the interval [1, 11] years, the average rate of change of height is ...
change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr
__
On the interval [11, 15] years, the average rate of change is ...
(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr
Even on this interval, the closest answer choice is C.
Hello there!
amd
Let me start with 8^-2
8^-2 = 1/8 * 8
8^-2 = 1/64
which equals to 0.015625 in decimal
8^ 0 = 1
Yep, that's the answer! Easy, isn't? Well you may have been wondering why 8^0 is equal to 1.
I quoted an explanation online that says: Think of "multiplication" as always including an extra "1" as a multiplier.
So it'd be like
8^ 0
8/8 = 1
Remember: Whenever a number has an exponent 0, the answer MUST be 1.
Thus,
8^0 is greater. As you can see, it is equal to 1, while the other one is equal to 0.01
I'm terrible at explaining stuff. I hope you find this answer somehow helpful :)
