Answer:
Inverse of exponential functions are logarithmic functions.
Step-by-step explanation:
Inverse functions exhibit a relationship where they undo each other mathematically. In this case, the inverse of an exponential function is a log function, where;
An exponential function y=a^x has its inverse as x=a^y
This exponential equation x=a^y is equivalent to the function y= logₐ x under the conditions; x=a^y : a>0 , a≠1
Step-by-step explanation:
let Rinus age be R
Anu's age is equal to 20+R and 6×R
20+R=6×R
20+R=6R
Collect like terms
20=6R-R
5R=20
Divide both sides by 5
R=20/5
R=4
Therefor Rinu is 4 years while Anu is 20+4 which is 24 years
C 10,628 because 400 times offer price (23.89) = $9,556, 400 times (50.46)= $20,184. $20,184-$9,556= $10,628profit.
