Answer 1

Sorry I couldn't help this one baffled me. I was trying t o do it as if I had a test.

Answer 2

Use natural log because it's base e

ln e .954 = -180x  (e is the base, you don't have to put it in the calculator)

so then x = -ln.954 / 180

Answer 3

Take the natural log or ln of both sides to get

ln(0.954) = - 180x

Then just divide by -180 to get your answer
