Answer:
The average rate of change of f(x) from 1 to 4 is -80.
Step-by-step explanation:
The average rate of change of f(x) from a to b is defined as
The average rate of change of f(x) from 1 to 4 is defined as
From the given table it is clear that the the value of the function is 244 at x=4 and 484 at x=1. So f(4)=244 and f(1)=484. Put these values in the above equation.
Therefore the average rate of change of f(x) from 1 to 4 is -80.
Answer:
2.meters
Step-by-step explanation:
Lenght of ladder = 4 m
θ = 30°
To obtain h;
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Hypotenus = 4 ; opposite = h
Sin 30 = h / 4
0.5 = h / 4
h = 0.5 * 4
h = 2 m
Hence, distance between th efoot of ladder and the base of the wall is 2 m
