Answer:
±16
The principle value is 16
Step-by-step explanation:
sqrt(8) * sqrt(32)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(8*32)
sqrt(256)
sqrt(16*16)
±16
The principle value is 16
Answer:
or 
Step-by-step explanation:
we know that
The volume of the cylinder (the well) is equal to

where
----> the radius is half the diameter

substitute


assume


1000x2x15=30000
30000-1000x15=15000
1000x15x5=75000
75000-1000x5=70000
100x15x15=22500
22500-15x100=21000
Investment of 1000 at 2% simple interest for 15 years will earn the least simple interest
Investment of 1000 at 15% simple interest for 5 years will earn the most simple interest
