Answer:
Length and Width = 10ft
Height = 5ft
Surface Area = 300 square feet
Step-by-step explanation:
Given
-- Volume
Let:
Volume (V) is calculated as:
Substitute 500 for V
Make H the subject
The tank has no top. So, the surface area (S) is:
Substitute 500/LW for H
Differentiate with respect to L and to W
and
Equate both to get the critical value
and
and
and
and
Make L the subject in
Substitute for L in
Cross Multiply
Divide both sides by 1000
Take cube roots of both sides
Substitute 10 for W in
Recall that:
So, the dimensions are:
and
The surface area is:
4 + 2h < -3
2h < -7
h < -3.5
x ∈ (-∞, -3.5)
For a monthly sales figures at 5600 and expected to fall for the following 9 months at a rate of 2% each month, the total sales for the next two years is mathematically given as
A=11968.04
<h3>What are total sales for the next two years (including the first January).?</h3>
Generally, the total sales is mathematically given as
A=5600(1-2/100)^9(1+4/100)^24
A=5600(.98)^9(1.04)^24
A=11968.04
In conclusion, total sales for the next two years
A=11968.04
