Answer:what is the unit
Step-by-step explanation:
I believe it’s B because it is not a function if there are 2 x values that are the same.
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:
X-int: (6,0) & (4,0)
Y-int: (0,-12)
Vertex: (5, 1/2)
AOS: x=5
Max/Min Value: (5, 1/2)
1st, 2nd, 4th. hope this helps
