MA_775_DIABLO [31]

Answer:

3,813.33 \:  {cm}^{3}

Step-by-step explanation:

Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

=  {20}^{3}  -  \frac{4}{3}  \times 3.14 \times  {10}^{3}  \\  \\  = 8000 -  \frac{4}{3}  \times 3.14 \times  1000 \\  \\   = 8000 -  \frac{4}{3}  \times 3140 \\  \\  = 8000 -  \frac{12560}{3}  \\  \\  = 8000 - 4,186.66667 \\  \\  = 3,813.33333 \\  \\  = 3,813.33 \:  {cm}^{3}

Let
Maksim231197 [3]

Answer:

3.3

Step-by-step explanation:

We determine the plane formed by u_1 and u_2. The normal to the plane is given by their cross product:

u_1\times u_2

\begin{pmatrix} - 2\\ - 4\\ 1 \end{pmatrix}\times\begin{pmatrix} - 4\\ 1 \\ - 4\end{pmatrix}=\begin{pmatrix} 15 \\ - 12\\ - 18\end{pmatrix}

The equation of the plane is then given by

15x-12y-18z=0

The distance between a vector \begin{pmatrix} x_1 \\ y_1 \\ z_1 \end{pmatrix} and a plane Ax+By+Cz +D =0 is given by

d=\dfrac{|Ax_1+By_1+Cz_1 +D|}{\sqrt{A^2+B^2+C^2}}

Comparing,

A = 15,\ B = - 12,\ C = -18,\ D = 0,\ x_1=3,\ y_1 =-8, \ z_1 =3

Substituting,

d=\dfrac{|(15\times3)+(-12\times-8)+(-18\times3)+0|}{\sqrt{15^2+(-12)^2+(-18)^2}}

d=\dfrac{|45+96-54|}{\sqrt{225+144+324}}=\dfrac{87}{\sqrt{693}}

d =\dfrac{87}{26.32\ldots}\approx 3.3
