Y+4=10(x+3)
Y+4=10x+30
Y=10x+26
To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the surface area and the volume of the tank:
2. Solve for in the second equation and substitute it into the first one.Then, you have:
3. Now, derivate:
4. When you solve for , you obtain:
5. Now, you must calculate :
Therefore, the dimensions are:
The sides of the base of the tank:
The height of the tank:
Answer:
What do you mean?
Step-by-step explanation:
All you need is to solve the problem
4-2|n+6|>=2
subtracting 4 from both sides
-2|n+6|>=-2
dividing by -2 and flipping sign of inequality
|n+6|<=1
-1<=n+6<=1 subtracting 6 from both sides
-7<=n<=-5
the conjunction will be -7<=n and -5>= n
which is choice a
