An aquarium with a square base has no top. There is a metal frame. Glass costs 10 dollars/m^2 and the frame costs 9 dollars/m. T
LenKa [72]
The volume is given as V = Lwh = 20 m^3.
Since the base is a square then V = L²h = 20 m^3
Rearranging, we have L = √(20/h).

For the metal frame:
8√(20/h) + 4h ==> [8 is multiplied to √(20/h) because there are 8 sides measuring L, and 4 is multiplied to h because there are 4 sides that have measure h.]

9[8√(20/h) + 4h]
=72√(20/h) + 36h = Cost of metal frame

For the glass:
Area of one square base = L² = 20/h
Area of one rectangular side = h√(20/h) 
Area of 4 rectangular sides = 4h√(20/h) 

10[20/h + 4h√(20/h)] = Cost of glass

C = 72√(20/h) + 36h + 10[20/h + 4h√(20/h)] 

(take note, we did not multiply 10 to the terms because 10 dollars is per unit area and not unit length.)

What is the equation of a line that passes through the point (6,3) and is perpendicular to a line with a slope of -3/2
SCORPION-xisa [38]

Answer:

  none of the above

Step-by-step explanation:

The perpendicular line will have a slope that is the negative reciprocal of the given slope, so it is ...

  m = -1/(-3/2) = 2/3

The point-slope form of the equation of the line with slope m through point (h, k) can be written ...

  y = m(x -h) +k

For this slope and the point (6, 3), the equation of the line is ...

  y = (2/3)(x -6) +3

  y = 2/3x -4 +3

  y = 2/3x -1 . . . . . matches none of the offered choices

_____

The attached graph shows this equation is the one that goes through the given point.
