Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
<h3>

</h3>
To solve for y cross multiply
That's
3( x - 1) = 2y
2y = 3x - 3
Divide both sides by 2 to make y stand alone
That's
<h3>

</h3>
We have the final answer as
<h3>

</h3>

Answer:
0.225989
Step-by-step explanation:
3x+9+x-11=180
4x-3=180
4x=180-3
4x/4x=177/4x
0.225989
Answer:
The area of a label is 
Step-by-step explanation:
we know that
The lateral area of a cylinder (label of the can) is equal to

we have that
A can is 4 inches wide
so
The diameter of the can is 4 inches
----> the radius is half the diameter
----> height of the label
substitute in the formula

Answer:
a)
, b)
.
Step-by-step explanation:
a) The graphic is enclosed to the problem. By visual inspection, an absolute maximum is found.

b) The exact method consists in the application of the First and Second Derivative Tests. First and second derivatives are, respectively:


The First Derivative Test consists in equalizing the first derivative to zero and solving the expression:


According to the second derivative, the critical point leads to a maximum. The remaining component is determined by evaluation the polynomial:


The exact solution is
, indicating that graphic solution leads to a good approximation.
