Step-by-step explanation:
The initial image of the photo is 2 in by 4 in.  The mat is 4 in by 6 in.
The new image is dilated by a scale of 2.  So we double the dimensions.  The new photo is 4 in by 8 in.  The new mat is 8 in by 12 in.

Answer: 1.2metres
Step-by-step explanation:
Five years ago, tree was 4.9m
Today, tree is 6.1m
Subtract 4.9m from 6.1m
Tree has grown by 1.2m
 
        
             
        
        
        
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
