Laim descended 5,050.25 feet and his elevation changed by -5,050.25.
Answer
42
step by step
5 times 11 - 2 times 11
2^2x=5^x−1
Take the log pf both sides:
ln(2^2x) = ln(5^x-1)
Expand the logs by pulling the exponents out:
2xln(2) = (x-1)ln(5)
Simpligy the right side:
2xln(2) = ln(5)x - ln(5)
Now solve for x:
Subtract ln(5)x from both sides:
2xln(2) - ln(5)x = -ln(5)
Factor x out of 2xln(2)-ln(5)x
x(2ln(2) - ln(5)) = -ln(5)
Divide both sides by (2ln(2) - ln(5))
X = - ln(5) / (2ln(2) - ln(5))
The answer is -8 I believe.
To put this into an equation, we get 7x-x=-48. This is equal to 6x=-48. When we divide we get -8.
> this is the sign for the larger absolute value
