Answer:
t = 6.67 seconds
Step-by-step explanation:
Given that,
The distance of Moon from Earth, 
The speed of the spacecraft, 
We need to find the time it take this spacecraft to fly to the moon from earth. Let the time is t.
We know that,
Speed = distance/time
So, the required time is equal to 6.67 seconds.
Answer:
169.09 degrees
Step-by-step explanation:
Interior Angle of a polygon with 33 sides = (n-2) x 180/n degrees = (33-2) x 180/33 degrees = 169.09 degrees
Answer:
A
Step-by-step explanation:
It can only be a bc its the only one with -4 as b
(2x - 3)*(x+4) =
2x*x + 2x*4 - 3*x - 3*4 =
2x^2 + 8x - 3x - 12 =
2x^2 + 5X - 12 =
a = 2; b = 5, c = - 12
Δ = b^2 - 4.a.c
Δ = 5^2 - 4.2.(-12)
Δ = 25 - 8. (-12)
Δ = 25 + 96
Δ = 121
x = -b±√Δ / 2.a
x = -5±√121 / 2.2
x = -5±11 / 4
x' = -5-11 / 4 = -16/4 => x' = -4
x" = -5+11 / 4 = 6/4 (÷2) => x" = 3/2
