Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
Answer:
$238.15
Step-by-step explanation:
8.25% = 8.25/100 or 0.0825
Multiply 0.0825 and 220 to get $18.15. That's how much the tax is.
Add 220 and 18.15 to get $238.15
Convert to degrees
34°18' is the same as 34° 18' 0"
34° 18' 0" = 34° + 18'/60 + 0"/3600
= 34.3°
putting tan(34.3) into a calculator in degree mode
tan ( 34°18' )= tan(34.3) = 0.6822
