The easy answer: If, say, B is the zero matrix, i.e.

then

Answer:
M(6,5) and G(2,9)
Step-by-step explanation:

B(3,6)
C(9,4)
m = [(3+9)/2 , (6+4)/2]
= (6,5)
M(5,9)
H(8,9)
G(x,y)
[(x+8)/2 , (y+9)/2]=(5,9)
(x+8)/2 = 5
x+8 = 10
x = 2
(y+9)/2 = 9
y+9 = 18
y = 9
G(2,9)

Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.
{country albums}:{jazz albums}=2:3
3{country albums} = 2{jazz albums}
{country albums} + {jazz albums} = 45
{jazz albums} = 45 - {country albums}
3{country albums} = 2(45 - {country albums})
3{country albums} = 90 - 2{country albums}
5{country albums} = 90
{country albums} = 18
