Wouldn’t you just subtract 2 from 2?

Christina plotted the shape of her garden on graph paper. she estimates that she will get about 15 carrots from each square unit

LekaFEV [45]

the shape of christina’s garden is a rectangle and trapezoid. The rectangle has a dimensions of 4 units by 2 units. The trapezoid upper base is 8 units and the lower base is 4 units and the height is 2 units

Area of the garden = area rectangle + area trapezoid

A = (LW) + 0.5( base1 + base2)(h)

A = ( 4 x 2) + 0.5 ( 8 + 4) (2)

A = 20 sq units

Number of carrots = 20 sq units x 15 carrots/ sq units

<span>= 300 carrots</span>

4. Let B = {(1,0,1),(0,1,2), (2, -1,0)}. (a) The vectors in B are dependent. Show this. (b) Find a non-trivial solution to an(1,

Vladimir79 [104]

Answer:

Step-by-step explanation:

Given are three vectors in set B.

To show that B is dependent

The determinant

$\left[\begin{array}{ccc}1&0&1\\0&1&2\\2&-1&0\end{array}\right] \\=1(2)-1(2) =0$

Hence vectors are dependent

b) The given equation $a_1(1,0,1) + a_2(0,1,2) + a_3(2, -1,0) = 0.\\$

Let us try parametrically

These 3 vectors are collinear and hence equation would be

$\frac{x-1}{0-1} =\frac{y-0}{1} =\frac{z-1}{2-1} =s\\(x,y,z) = (1-s, s, 1+s)$

c) Basis for B would be only 2 dimensional

i.e. any two vectors out of 3 form basis

The basis would be (1,0,1) and (0,1,2)

mariarad [96]

The mountain climber has travelled 75 feet below sea level while descending down a cliff.

Given:

A mountain climber at sea level starts descending down a cliff.
Her location can be represented by -75 ft.

To find:

The distance travelled by a mountain climber.

Solution

Distance ascending above sea level is taken in a positive direction.
Distance descending down sea level is taken in a negative direction.
This negative and positive only represents the direction

The location of mountain climber after descending from cliff = -75 ft

The distance covered by the mountain climber = 75 ft

The mountain climber has travelled 75 feet below sea level while descending down a cliff.
