Answer:
x=0.69897009
Step-by-step explanation:
expand by logarithms
10^x=5
=log(10^x)=log(5)
=x log(10)=log (5)
log base 10 of 10 is 1
x.l =log(5)
multiple bothside by 1
x=log(5)
x=0.6989709
Answer:
Growth when: b>1.
Decay when: 0<b<1.
Step-by-step explanation:
Any function in the form 
, where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.
if 0 < b < 1. It is an example of an exponential decay.
The general shape of an exponential with b > 1 is an example of exponential growth.
Hence,
An exponential function is expressed in the form 
The relation represents a growth when b >1 and a decay when 0<b<1.
Answer:
16.65
Step-by-step explanation:
37 * 0.45 = 16.65
My estimate is about 200$ but I did it in my head so you might want to check on a calculator. :) hope this helped!
