Answer:
A) 12.1 , 12.01
B) infinitely large 
Step-by-step explanation:
Give that the function f(x)=x2 describes the area of the square, f(x), in square inches, whose sides each measure x inches. If x is changing. 
Using the formula 
(f(a + h) - f(a))/h
as x changes from 6 inches to 6.1 inches 
a = 6, h = 0.1 
= [f(6.1) - f(6)]/0.1
= (6.1^2 - 6^2)/0.1
= (37.21 - 36)/0.1
= 1.21/0.1
= 12.1
and when x changes from 6 inches to 6.01 inches. 
a = 6, And h = 0.01
Using the same formula 
(f(a + h) - f(a))/h
= [f(6.01) - f(6)]/0.01
= (6.01^2 - 6^2)/0.01
= (36.120 - 36)/0.01
=0.1201/0.01
= 12.01
B) the instantaneous rate of change of the area with respect to x at the moment when x = 6 inches is infinitely large since h = 0
 
        
             
        
        
        
Answer:
There is something already at the positive 2 place and you are just subtracting 2 because of (-2)

Surface Area of a Cylinder Formula: SA = 2πrh + 2πr²
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>r</em> = 11 in
<em>h</em> = 23 in
<u>Step 2: Find Surface Area</u>
- Substitute in variables [Surface Area of a Cylinder Formula]:                       SA = 2π(11 in)(23 in) + 2π(11 in)²
- Evaluate exponents:                                                                                         SA = 2π(11 in)(23 in) + 2π(121 in²)
- Multiply:                                                                                                             SA = 506π in² + 242π in²
- Add:                                                                                                                   SA = 748π in²
 
        
             
        
        
        
Answer:
112cm
Step-by-step explanation:
4×2=8
8×2=16
4×8=32
8+16+32= 56×2= 112cm
Hope this helps!
