The following statement is either true​ (in all​ cases) or false​ (for at least one​ example). If​ false, construct a specific e
matrenka [14]

Answer:

False, counterexample below

Step-by-step explanation:

Denote the unit vectors of R^3 by e_1=(1,0,0), e_2=(0,1,0), e_3=(0,0,1). Now consider v_1=e_1, v_2=2e_1 and v_3=e_3. We have that v_1, v_2,v_3 \in \mathbb{R}^3. Also, the vector v_3 is not a linear combination of v_1, v_2 because any linear combination of these two vectors will have third coordinate zero, but v_3 has third coordinate 1 so they can't be equal.

However, the set \{v_1, v_2,v_3\} is not linearly independent, because 2v_1-v_2+0v_3=0 is a non-trivial linear combination of these vectors that equals zero.

Look at the Hexagon below
Mama L [17]

Answer:

Angle 9: 60°

Angle 10: 30°

Side = radius = 40sqrt(x/3)

Area = [800sqrt(3)]x

Step-by-step explanation:

Total angle in a hexagon:

(6 - 2) × 180

720

Each interior angle:

720/6 = 120

angle 9 = 120/2 = 60

Angle 10 = 60/2 = 30

sin(60) = 20sqrt(x)/r

r = 20sqrt(x) ÷ sqrt(3)/2

r = 40sqrt(x/3)

Side:

sin(30) = ½s/(40sqrt(x/3))

½s = 20sqrt(x/3)

s = 40sqrt(x/3)

Area = (3sqrt(3))/2 × s²

Area = 3sqrt(3)/2 × 1600x/3

Area = [800sqrt(3)]x

Oksana_A [137]
An=a1+d (n-1)
a1= 7
find d
Let's use a2
a2=1
1=7+d (2-1)
1=7+d
-7 both sides
d=-6
explicit formula is

an=7+-6 (n-1)

a14=?
a14=7-6 (14-1)
a14=7-6×13
a14=7-78
a14=-71
