<span>For this case we have the following expression:
</span> 

<span> We are going to make the following change of variables:
 </span>

 <span>Rewriting the expression we have:
 </span>

 <span>Factoring the expression we have:
 </span>

 <span>Canceling similar terms we have:
 </span>

 <span>Returning the change we have:
 </span>

<span> The resctrictions of the function are those that make the denominator equal to zero.
 We have then:
 </span>

Answer:
h<2
Step-by-step explanation:
5×2h+5×8<60
10h+40<60
10h<60-40
<u>1</u><u>0</u><u>h</u><u><</u><u>2</u><u>0</u>
<u>1</u><u>0</u><u>. </u><u> </u><u> </u><u> </u><u>1</u><u>0</u>
h<2

Step-by-step explanation:
The volume of a pyramid or cone is:
V = ⅓ Ah
where A is the area of the base and h is the height.
The pyramid has a square base, so:
A = s²
A = (7 cm)²
A = 49 cm²
The height is 14 cm, so the volume is:
V = ⅓ (49 cm²) (14 cm)
V = 686/3 cm³
V ≈ 228.67 cm³
 
        
             
        
        
        
Some rational numbers are
2.71, 2.72, 2.73, 2.74, 2.75, 2.76, 2.77, 2.78, 2.79
2.711, 2.712 2.713....
2.721, 2.722, 2.723....
2.731....
I think you get the point! Hope this helped!
