Answer:
a) Log ( 2 ) = 4t Log ( 83/80 )
b) 4.7 years
Step-by-step explanation:
Attached below is the detailed solution
<u>a) exponential statement in log form for an investment at 15% quarterly </u>
Log ( 2 ) = 4t Log ( 83/80 )
n = 4 , r = 15
<u>b) using change to base to find double time in yr </u>
Double time in yr
t = Log ( 2 ) / 4log ( 83/80 )
= 4.7 years
Answer:
A=$21930.52
Step-by-step explanation:
Given data
Principal =44000
Time =5years
Rate of depreciation =13%
The expression for the depreciation is
A=P(1-r)^t
Substitute
A=44000(1-0.13)^5
A=44000(0.87)^5
A=44000*0.4984209207
A=21930.52
Answer:
x ≥ -2 2/3
Step-by-step explanation:
multiply each side by x-4, you get:
3x + 8 ≥ 0
3x ≥ -8
x ≥ -8/3
