Step-by-step explanation:
- 5^-2= 1/25 (as when taken up 25 it becomes 5^-2).
- 2^5= 32 (when we multiply 2 for 5 times, we get 32).(2×2×2×2×2)
- 2^-4=1/16 (as when we take up 16 we get 2^-4)
- 5^3=125 (when we multiply 5 for 3 times we get 125)(5×5×5)

Answer:
0.85 of the original piece of lumber remains.
Step-by-step explanation:
Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.
2.5 - 1.65 =
2.50 - 1.65 = 0.85.
Therefore, 0.85 of the original piece of lumber remains.

I not 100% sure but I chose C.
Hope this helps.. but good luck :)
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
