Answer:
   an = 67 -11(n -1)
Step-by-step explanation:
The terms of your arithmetic sequence have a common difference of -11. The first term is 67.
These values can be used in the generic formula for the n-th term:
   an = a1 +d(n -1) . . . . . . first term a1, common difference d
   an = 67 -11(n -1) . . . . . formula for the n-th term
 
        
             
        
        
        
The slope is -2. You find this by putting the rise between the two points over the run.
        
             
        
        
        
We should use lb to convert weight to kg
let unknown lb be = X
14 lb = 1 stone 
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14 
 X = 126 / 1 = 126 lb
9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
 Y = 126 / 2.2 = 57.3 kg
So 9 stone = 126 lb = 57.3 kg

Answer:
D.   ft²
 ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form, 
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit =  a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into  
Thus:
4,356,000 = 3. Substitute the values of the variables into  
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6
