Answer:

Part 1) 132\ ft^{2}

Part 2) 27\ ft^{2}

Step-by-step explanation:

Part 1) we know that

The area of the figure is the area of one trapezoid multiplied by 2

<u>Find the area of one trapezoid</u>

A=\frac{1}{2}(b1+b2)h

we have

b1=9\ ft

b2=15\ ft

h=11/2=5.5\ ft

substitute

A=\frac{1}{2}(9+15)5.5=66\ ft^{2}

<u>Find the area of the figure</u>

2*66\ ft^{2}=132\ ft^{2}

Alternative Method

The area of the figure is equal to the area of a rectangle plus the area of triangle

so

A=11*9+\frac{1}{2}(11)(15-9)\\ \\A=99+33\\\\A=132\ ft^{2}

Part 2) we know that

The area of the hexagon is equal to the area of one triangle multiplied by 6

<u>Find the area of one triangle</u>

A=\frac{1}{2}bh

we have

b=3\ ft

h=3\ ft

substitute

A=\frac{1}{2}(3*3)=4.5\ ft^{2}

6*4.5\ ft^{2}=27\ ft^{2}

I need help with 8 9 thanks
sasho [114]
#8: $900. (I found this answer by multiplying 3000 and 0.3 by the way)
#9: 160 miles. I found this answer by multiplying 80 by two, since two halves/50% make a whole or 100%.

Determine whether the set of vectors <img src="https://tex.z-dn.net/?f=%20v_%7B1%3D%283%2C2%2C1%29%2C%20v_%7B2%7D%20%3D%28-1%2C-

Since each vector is a member of \mathbb R^3, the vectors will span \mathbb R^3 if they form a basis for \mathbb R^3, which requires that they be linearly independent of one another.

To show this, you have to establish that the only linear combination of the three vectors c_1\mathbf v_1+c_2\mathbf v_2+c_3\mathbf v_3 that gives the zero vector \mathbf0 occurs for scalars c_1=c_2=c_3=0.

c_1\begin{bmatrix}3\\2\\1\end{bmatrix}+c_2\begin{bmatrix}-1\\-2\\-4\end{bmatrix}+c_3\begin{bmatrix}1\\1\\-1\end{bmatrix}=(0,0,0)\iff\begin{bmatrix}3&-1&1\\2&-2&1\\1&-4&-1\end{bmatrix}\begin{bmatrix}c_1\\c_2\\c_3\end{bmatrix}=\begin{bmatrix}0\\0\\0\end{bmatrix}

Solving this, you'll find that c_1=c_2=c_3=0, so the vectors are indeed linearly independent, thus forming a basis for \mathbb R^3 and therefore they must span \mathbb R^3.
