Answer:
A
Step-by-step explanation:
To calculate the scale factor k, find the ratio of corresponding sides
 =
 =  = 6
 = 6
 =
 =  = 6
 = 6
Hence the scale factor k = 6 → A
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Let initial number of plants =100
Increase I year                        60
Number after 1 year               160
Increase IIyear 60%                96
Number after II year               256
Increase in III year 60%           153.6 
and so on
In general if t is number of years and N number of plants after n years
the expression would be

In other words, the expressions wouldbe the same as amount after t years of compound interest.
 
        
             
        
        
        
The value of cos 4x from the given identity is 0.999
<h3>Trigonometry identity</h3>
Given the cosine identity
cos8x = 13/36 
Determine the value of x
8x = arccos(13/36)
8x = 0.36111
x = 0.36111/8
x = 0.04514
Determine the value of cos4x
cos4x = cos4(0.04514)
 cos4(0.04514) = 0.999
Hence the value of cos 4x from the given identity is 0.999

Answer:
1/3.
Step-by-step explanation:
The 2 events are independent so we multiply the 2 probabilities.
Prob(rolling an odd number) = 3/6 = 1/2.
Prob(rolling a number greater than 2) = 4/6 = 2/3.
The required probability = 1/2 * 2/3
= 2/6
= 1/3.
