Answer:
The exact answer is 16.6666666667. Rounded would be about 17.
Step-by-step explanation:
Hope i was right and this helped!
This is the future value quadrupled in t years at an annual interest rate of 6.5% compounded daily. We need to find t.
1*(1+0.065/365)^(365t)t=4
take log on both sides,
365t(log(1+0.065/365)=log(4)
=>
365t=log(4)/log(1+0.065/365)
t=(log(4)/log(1+0.065/365))/365
=(1.38629/.000178066)/365
=21.33 years
Check with the rule of 69, applicable to continuous compounding (an approximation to current problem) to double money, it take 69/interest rate in % years.
=69/6.5
=10.62 years
To double twice (quadruple), it takes twice 10.62
=21.24 years, not that far from 21.33 that we got earlier.
Step-by-step explanation:
y=(x-d)²+7
y-7=(x-d)²
√(y-7)=x-d
d=x-√(y-7)
I would appreciate if my answer is chosen as a brainliest answer
Answer:
46656
Step-by-step explanation:
6*6*6*6*6*6*6 = 6x
Multiply the terms.
279936 = 6x
Divide 6 into both sides.
279936/6 = 6x/6
= 46656
