Answer:

C. 1680 m³

Step-by-step explanation:

Find the base of the triangular prism:

$\frac{1}{2}*28m*12m=\\14m*12m=\\168m^2$

Now we can multiply the base by the height, 10.

$168m^2*10m=\\1680m^3$

Our answer is C. 1680 m³

What is the product

djverab [1.8K]

Answer:

The product of given matrix is $AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}$

Step-by-step explanation:

Given : Two matrix

$A=\begin{pmatrix}3&6&1\\ 2&4&0\\ 0&6&2\end{pmatrix}$

and $B=\begin{pmatrix}2\\ \:0\\ \:1\end{pmatrix}$

We have to find the product of given matrix

$AB=\begin{pmatrix}3&6&1\\ 2&4&0\\ 0&6&2\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}$

Multiply the rows of first matrix by the columns of second matrix , we have,

$\begin{pmatrix}3&6&1\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=3\cdot \:2+6\cdot \:0+1\cdot \:1$

$\begin{pmatrix}2&4&0\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=2\cdot \:2+4\cdot \:0+0\cdot \:1$

$\begin{pmatrix}0&6&2\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=0\cdot \:2+6\cdot \:0+2\cdot \:1$

$=\begin{pmatrix}3\cdot \:2+6\cdot \:0+1\cdot \:1\\ 2\cdot \:2+4\cdot \:0+0\cdot \:1\\ 0\cdot \:2+6\cdot \:0+2\cdot \:1\end{pmatrix}$

On , simplifying , we get,

$AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}$

Thus, the product of given matrix is $AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}$

A circular cake with a radius of 8 inches is cut from the center into 6 equal pieces. How many inches wide, to the nearest tenth

aalyn [17]

Answer: 8.4 inches.

Step-by-step explanation:

We know that the circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "r" is the radius of the circle.

We know that the circular cake (whose radius is 8 inches) is cut from the center into 6 equal pieces. Then, you need to divide the circumference of this circular cake by 6 to find the width of the outer edge of each piece of cake.

Therefore, this is (to the nearest tenth of an inch):

$C=\frac{2\pi (8in)}{6}\\\\C=8.4in$

Give an example of a quadratic equation with 2 + 3i as one of its solutions

Anastasy [175]

Answer:

Step-by-step explanation:

roots are (2+3i) and (2-3i)

reqd. eq. is (x-2-3i)(x-2+3i)=0

or (x-2)²-(3i)²=0

or x²-4x+9-9i²=0

or x²-4x+9+9=0

or x²-4x+18=0
