Solution:
Given;
Thus, the yearly interest rate on Bianca's account is 2.4%
It’s should be letter b I hope you have a great day
Let r be the decay rate (time in minutes) 17 = 20 e^(5r) 0.85 = e^(5r) ln 0.85 = 5r similarly, ln 0.5 = hr ... where h is the half-life, so dividing the 2 equations, ln 0.85 / ln 0.50 = 5r / hr = 5/h h = 5 ln 0.50 / ln 0.85 h = 21.3 min b) 1/20 = 0.05, so ln 0.85 = 5r ln 0.05 = tr t = 5 ln 0.05 / ln 0.85 t = 92.2 min
Answer:
Step-by-step explanation:
The X intercept is 1 and the y-intercept is 1 aswell.
I'm not sure but I think, f(s)=-4[x]-3
