A lamina with constant density rho(x, y) = rho occupies the given region. Find the moments of inertia Ix and Iy and the radii of

jenyasd209 [6]

Answer:

Ix = Iy = $\frac{ρπR^{4} }{16}$

Radius of gyration x = y = $\frac{R}{4}$

Step-by-step explanation:

Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.

Mass of disk = ρπR2

Moment of inertia about its perpendicular axis is $\frac{MR^{2} }{2}$ . Moment of inertia of quarter disk about its perpendicular is $\frac{MR^{2} }{8}$ .

Now using perpendicular axis theorem, Ix = Iy = $\frac{MR^{2} }{16}$ = $\frac{ρπR^{4} }{16}$ .

For Radius of gyration K, equate MK2 = MR2/16, K= R/4.

A store is having a sale on trail mix and jelly beans. For 7 pounds of trail mix and 9 pounds of jelly beans, the total cost is

Vlad [161]

Answer:

The cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.

Step-by-step explanation:

Let each pound of trail mix cost $x$ dollars and each pound of jelly beans cost $y$ dollars.

Given:

7 pounds of trail mix and 9 pounds of jelly beans cost $ 37.

So, $7x+9y=37$ --------------- 1

Also, 5 pounds of trail mix and 3 pounds of jelly beans cost $ 17.

So, $5x +3y=17$ --------------- 2

Multiplying equation 2 by -3, we get

$(5x +3y=17)\times -3\\-15x-9y=-51-------- 3$

Now, adding equations 1 and 3, we get

$7x+9y-15x-9y=37-51\\7x-15x=-14\\-8x=-14\\x=\frac{-14}{-8}=\$1.75$

Now, plug in $x=1.75$ in equation 1 and solve for $y$ .

$7(1.75)+9y=37\\12.25+9y=37\\9y=37-12.25\\9y=24.75\\y=\frac{24.75}{9}\\ y=\$2.75$

Therefore, the cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
