What is BD?
A. 10
B. 12
C. 13
D. 14

B 12.

Step-by-step explanation:

BE = ED  (as E is the center of BD - property of a kite).

By Pythagoras:

10^2 = 8^2 + BE^2

BE^2 = 10^2 - 8^2 = 36

BE = 6

So BD = 2*6 = 12.

answer:

1. 0.04

2. 0.15

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
