N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
I’m pretty sure it’s talking about the amount of water regulated to food for example how much water does gelatin have 90% why? How? Because the food produces its self with water making it absorbed and the best way the question is asking is how many __in units.
Answer:
if a = b and b= c then a,b and c are all equal
Answer:
lnx/ln4
Step-by-step explanation:
Given
y=4^x
In order to find the inverse of the function the first step is to replace the y with x and x with y
So,
Replacing x with y and y with x
x= 4^y
We have to find the value of y explicitly to find the invers.
The above equation can also be written as:
4^y=x
As the variable is in exponent, to bring it down, ln has to be taken on both sides.
ln 4^y =ln x
The power of will be multiplied with the ln.
y ln4=lnx
y=lnx/ln4
So,
The inverse is lnx/ln4 ..
