Answer:
The average rate of change of the function from x=1 to x=2 will be: 10.5                
Step-by-step explanation:
Given the function

at x₁ = 1, 
f(x₁) = f(1) =  -14/(1)² = -14/1 = -14
at x₂ = 2,
f(x₂) = f(2) = -14/(2)² = -14/(4) = -3.5
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate of change = [f(x₂) - f(x₁)] / [ x₂ - x₁]
                                         = [-3.5 - (-14)] / [2 - 1]
                                         = [-3.5 + 14] / [1]
                                         = 10.5 / 1
                                         = 10.5
Therefore, the average rate of change of the function from x=1 to x=2 will be: 10.5                      
 
        
             
        
        
        
Answer:
d = 1.46 m
Step-by-step explanation:
We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:
From the question given above, 
F is inversely proportional to square of d. This can be written as:
F ∝ 1/d²
F = K/d²
Cross multiply 
K = Fd²
But:
Force (F) = 0.006 N
Distance (d) = 4 m
Constant (K) =? 
K = Fd²
K = 0.006 × 4²
K = 0.006 × 16
K = 0.096 Nm²
Therefore, the relationship between the force (F) and the distance (d) is:
F = K/d²
F = 0.096 / d²
Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:
Force (F) = 0.045 N
Constant (K) = 0.096 Nm²
Distance (d) =? 
F = K/d²
0.045 = 0.096 / d²
Cross multiply 
0.045 × d² = 0.096
Divide both side by 0.045
d² = 0.096 / 0.045
Take the square root of both side. 
d = √(0.096 / 0.045)
d = 1.46 m.
