Answer:
3^-5 or 1/3^5(b)
Step-by-step explanation:
3⁴•3^-9
When bases are same powers are to be added
So the above expression becomes
3^4+(-9)
3^4-9
3^-5
No beacuse 1/4 would be less that 1/2 it's common sense
Answer:
The last one
Step-by-step explanation:
If you look at a graph, none of the line should overlap each other vertically. If a graph overlaps anywhere vertically, it is not a function.
They can play both if they wanted to......
A= πr^2
r=9
A= π(9)^2
A= 9x9=81
A=81π
In case that you have to use π
Multiply π(3.14)
3.14 times 81=254.34
