Let V be a vector space, and let v1, v2, v3 and v4 be linearly independent vectors in V . In parts (a) and (b) below, determine

whether each of the given sets of vectors is linearly independent or linearly dependent. Prove your answers using the definition.
u1 = v1 − 7v3, u2 = v1, u3 = v3, u4 = v3 + v4.

Answer:

Step-by-step explanation:

u_3 = v_3 and  u_2 = v_1

u_1= v_1 -7 v_3

Replace the first line to the second line, you have u_1= u_2-7u_3

That shows \{u_1, u_2, u_3,u_4\}

is not linear independent.

Find the area of a regular hexagon with apothem 2√3 mm. Round to the nearest whole number.
Varvara68 [4.7K]
Join the center of the hexagon with the 2 base angles.

An equilateral triangle, with side length x, is formed.

(remark: a regular hexagon is made up of 6 equilateral triangles with equal length)

The height 2 \sqrt{3} forms 2 congruent right triangles with :

hypotenuse= x, side_1=x/2, and side_2= 2 \sqrt{3}.

From the pythagorean theorem we have:

x^{2} = ( \frac{x}{2} )^{2}+(2 \sqrt{3})^{2}

x^{2} =  \frac{ x^{2} }{4} +12

\frac{3}{4} x^{2} =12

x^{2} = \frac{12*4}{3}=4*4

thus, x=4.

The area of the triangle is 1/2 * 4 * 2 \sqrt{3}=6.93 (mm squared)

The area of the hexagon is 6* the area of the triangle = 42 (mm squared)


Answer: a. 42 (mm squared)

The length of a rectangle is 2 more than twice the width. The perimeter is 76 feet. Find the length and width of the rectangle.
vlabodo [156]
So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
