Answer:
15.6
Step-by-step explanation:
10 ^ -3 = 0.001
10 ^ -2 = 0.01
10 ^ -1 = 0.1
10 ^ 0 = 0
10 ^ 1= 10
10 ^ 2 = 100
10 ^ 3 = 1000
False. consider u1 = (0, 0, 0), u2 = (1, 0, 0), u3 = (0, 1, 0), and u4 = (0, 0, 1).

You give us the answer right now. It's the answer to :
<span>If {u1, u2, u3} does not span R3, then neither does {u1, u2, u3, u4}.

Answer:
arc DB length = 14π feet
Step-by-step explanation:
Assuming point A is the center of the circle, arc DC has measure 180°. Arc DB has measure 40° less, so is 140°. Since you want this in terms of π, we need to convert the degree measure to radians. We do that by multiplying by (π/180) radians per degree:
arc DB = 140° = 140°(π/180°) radians
__
Now that we know the arc measure in radians, we can find the length of the arc. It is given by the formula ...
s = rθ
where r represents the radius and θ is the measure of the arc in radians.
The arc length is ...
s = (18 ft)(7π/9) = 14π ft
Arc DB has a length of 14π feet.
