Solve. If a gallon of milk costs $3 now and the price is increasing 10% each year, how long before a gallon of milk costs $10?
Lelechka [254]

Answer: 12.63 years

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

A = P (1 + r) t  

Where:  

p = original price

r = increasing rate (decimal form)  

t= years  

A = price after t years  

10= 3 (1 + 10/100) t  

10= 3(1.1)^t

10/3= 1.1^t

log 10/3 = log 1.1^t

log 10/3 = t log 1.1

log (10/3)/ log 1.1 =t

t = 12.63 years

Explain in more detail about one to one and onto function?
Tpy6a [65]
For one to one function each element in the domain is mapped on to an one and only one element in the co-domain.

The could be some elements in the co-domain that are not being used.

For a function to be one to one, then for

f(x) = f(y)
if and only if

x = y

For an onto function all the elements in the co-domain must be used up.

In order words, the co-domain=Range

The condition is
f(x) \rightarrow \: y
Meaning each OBJECTshould have an  IMAGE
