A shopper is standing on level ground 800 feet from the base of a 250 foot tall department store the shopper looks up and sees a

Density (D) is calculated as mass (m) divided by volume (v).
                                   D = m / v
The volume change is determined by measuring the water level before and after the object is introduced to the beaker,
                                   v = 23.1 mL - 18.5 mL = 4.6 mL
Substituting into the density formula,
                                   D = 8.24 g / 4.6 mL = 1.79 g/mL
Therefore, the density is roughly 1.79 g/mL.

Answer:Ix = Iy =  a^4 / 12

Ixy = a^4 / 24

Step-by-step explanation:

Solution:-

- Start by sketching the right-angled isosceles triangle as illustrated in the attachment.

- The density (ρ) functions multivariably based on coordinates (x and y).                              ρ ( x, y ) = k*(x^2 + y^2)

Here,  k represents the coefficient of proportionality.

- The lamina and density are symmetrical across the line y = x.  (refer to the attachment). The center of mass must be along this line.

- The coordinates of centroid ( xcm and ycm) are represented as:

                           

- Given that xcm = ycm, these points lie along the line y = x.

- Compute the mass of the lamina (m):

                           

- Evaluate the Moment (My):

                     

- Determine ( xcm = ycm ):

               

xcm = ycm = ( ka^5 /15 ) / ( ka^4/6) =

2a/5    

   

- Now utilizing the relations for Ix, Iy and I: We find:                    Ix = bh^3 / 12                    Iy = hb^3 / 12

Where,        h = b = a.... (Right angle isosceles)

                   

Ix = Iy =  a^4 / 12

                   Ixy = b^2h^2 / 24

                   Ixy = a^4 / 24
