Answer:
67.3km/h
Step-by-step explanation:
Find the amount of time it took from 10:12 to 11:18.
Which is 66 minutes. 
Find the average speed. 
Formula of average speed = 
Total distance/time
Which is, 
74/66 = 1.121 (recurring decimal) 
1.121 x 60 = 67.26km/h
= 67.3km/h (Estimated to 1 dp)

Answer:
Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠40 as the reference angle,
x represents the adjacent side of the right angle triangle.
4 represents the opposite side of the right angle triangle.
To determine x, we would apply 
the Tangent trigonometric ratio. 
Sin θ = opposite side/hypotenuse. Therefore,
Tan 40 = 4/x 
x = 4/Tan 40 = 4/0.839
x = 4.8
 
        
             
        
        
        
Answer:
option-B
Step-by-step explanation:
We are given 
At the start of the year, 15 chameleons were introduced into a zoo
so, 
The population of chameleons is expected to grow at a rate of 41.42% every year
so, r=0.4142
and x represents the number of years since the chameleons were introduced into the zoo
now, we can set equation to find total population 
and we get 

now, we can plug values


Average rate of change between 2 years and 4 years:
we can use formula 

now, we can plug values


Average rate of change between 4 years and 6 years:
we can use formula 

now, we can plug values


Average rate of change between 6 years and 8 years:
we can use formula 

now, we can plug values


now, we will check each options
option-A:
we can see that 


So, this is FALSE
option-B:

So, this is TRUE
option-C:
This is FALSE
option-D:
we got 

so, this is FALSE
