Answer: 8r = 256 is the expression. There are 32 rooms on each floor.
 
        
             
        
        
        
A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675
t= log 18.6/ log 1.0675
t=44.75 years

Answer:

Step-by-step explanation:
we have

This is the equation of the line in point slope form
where
The slope is m=1
The point is (4,8)
Convert to slope intercept form
Isolate the variable y
Adds 8 both sides

Combine like terms

Answer:
After 16 years …mr James age =4X+16 and his son's age will be X+16
As per the question in 16 years his age will be 2 twice 
(4X+16)=2(X+16)so by simplifying this we will get 2X=16..and X=16/2=8
