Answer:
The answer to this question is: 12.96 ft ≈ 13 ft
Step-by-step explanation:
Data
Area 168 ft²
Length = ?
Volumen = 0.42 gallons
But we do not need the volume of paint because we know that the wall is squared-shape.
Only we need to know the formula to obtain the area of an square.
Formula area = length²
So 168 = length²
Finally √168 = length
length = 12.96 ≈ 13 ft
Answer:
Step-by-step explanation:
The top has area (3 cm)(5 cm), or: 15 cm^2
The bottom has the same area: 15 cm^2
Each of the ends has the area (3 cm)(2.5 cm): 7.5 cm^2
7.5 cm^2
Each of the sides has the area (2.5 cm)(5 cm) 12.5 cm^2
12.5 cm^2
-------------------
70 cm^2
The total lateral area is 70 cm^2
So 25 goes into 21 how many times? 1. Add that 1 to the 3 making 4.
Then how much is left over of the 25 & 21? 4.
Making it 4 4/21
I suppose the integral could be
In that case, since 
as 
, we know 
. We also have 
, so the integral is approach +1 from below. This tells us that, by comparison,
and the latter integral is convergent, so this integral must converge.
To find its value, let 
, so that 
. Then the integral is equal to
