A rectangular building with a square base is being designed to minimize heat loss. The building designers state that the volume
Arturiano [62]

Answer:

y = 4000/x²

Step-by-step explanation:

The volume of the building is expressed as;

V = x²y where;

x is the length and width of the base.

y is the height of the building

Given

Volume V = 4000m³

Substitute the given volume into the equation as shown;

4000 = x²y

Make y the subject of the formula by dividing both sides by x²

4000/x² = x²y/x²

4000/x² = y

Rearrange

y = 4000/x²

Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

The figure is mad up of two shapes? A semicircle and a rectangle
musickatia [10]

Answer:

  Your answer choice is correct.

Step-by-step explanation:

The length of the semicircle is ...

  s = π·r = π(4 in)

The three sides of the rectangular section total ...

  9 in + 8 in + 9 in = 26 in

The sum of these lengths make up the perimeter of the figure:

  P = 4π in + 26 in

  P = (4π +26) in

If P (x,y) is the point on the unit circle defined by real number 0, then csc0=_.​
dezoksy [38]

Answer:

cscθ = \frac{1}{y}

Step-by-step explanation:

cscθ = \frac{Hypotenuse}{opposite}

For a unit circle, radius = 1

hence, hypotenuse = 1

opposite = y

cscθ = \frac{1}{y}
