Given the following matrices, what 3 elements make up the first column of the product matrix DA?

Misha Larkins [42]

We have to figure out what the product of DA is,

$\begin{bmatrix}-1&2&3\\8&-4&0\\6&7&1\\ \end{bmatrix}\begin{bmatrix}1\\3\\5\\ \end{bmatrix}=\begin{bmatrix}a\\b\\c\\ \end{bmatrix}$

We know that,

$\begin{bmatrix}a&b&c\\d&e&f\\g&h&i\\\end{bmatrix}\begin{bmatrix}x\\y\\z\\\end{bmatrix}=\begin{bmatrix}ax+by+cz\\dx+ey+fz\\gx+hy+iz\\\end{bmatrix}$

So,

$a=-1\cdot1+2\cdot3+3\cdot5=-1+6+15=20$

$b=8\cdot1+(-4)\cdot3+0\cdot5=8-12=-4$

$c=6\cdot1+7\cdot3+1\cdot5=6+21+5=32$

So the solution is,

$a,b,c=\boxed{20,-4,32}$

Hope this helps :)

NEED RN, WORTH 50! What is the value of x?

xxTIMURxx [149]

Answer:

$x = 5$

Step-by-step explanation:

Step 1: Make an equation

$\frac{32}{40} = \frac{4}{x}$

Step 2: Cross multiply

$\frac{32}{40} = \frac{4}{x}$

$32 * x = 4 * 40$

$32x = 160$

Step 3: Divide both sides by 32

$32x / 32 = 160 / 32$

$x = 5$

Answer: $x = 5$

Isabella uses the equation to find the volume of the cone below.

Rufina [12.5K]

Answer:

The correct answer option is: Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$

Step-by-step explanation:

We are given a diagram of a cone with height $9 cm$ and area of the base (circle) $12 \pi cm^ 2$ .

Isabella uses the equation $V = \frac { 1 } { 3 } ( 12 ) ^ 2 ( 9 ) \pi$ and we are to find the error that she is making in finding the volume of this cone.

The volume of a cone is given by: $\pi r^2\frac{h}{3}$ out of which $\pi r^2$ represents the area of the base (circle).

Therefore, Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$ .
