Answer:
The mid-point of the given line segment is:(5.5,-6.5)
Step-by-step explanation:
let us consider two points A and B with coordinates (a,b) and (c,d) respectively.
let C be the mid point of A and B then then the coordinates of C is given by 
.
in the given question (a,b)=(9,-8) and (c,d)=(2,-5) so the mid point of these two points are 
=(5.5,-6.5)
Hence, the coordinates of the midpoint of the line segment with endpoints B(9,-8) and C(2,-5) is (5.5,-6.5).
Answer:
Step-by-step explanation:
Volume of a cone:
Take 
as 3, as mentioned in the question
'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}
'h' is 'height'
{multiply 108 with 5 and then divide the answer by 3}

Answer:
we should know that :
sin ( a + b ) = sin a * cos b + sin b cos a
For the given equation :
sin (π + q) = sin π * cos q + sin q * cos π
sin π = zero and cos π = -1
∴ sin (π + q) = 0 * cos q + sin q * (-1) = - sin q
<u>Another solution:</u>
The angle (π + q) lies in the third quarter ⇒ (1)
(π + q) and (-q) are supplementary angles ⇒ (2)
From (1) and (2)
sin(π + q) = -sin q
It would be 11 if I’m reading this right
