Answer:
speed = 796142.197 km/hr
Step-by-step explanation:
solution
we consider here orbit around galactic center is circular so
circumference formula will be here
circumference C = 2πr ........1
here we know r = 27000
so
circumference C = 2 π × 27000
C = 169560 light year
so
we travel 169560 light year in 230000000 years
so distance will be
distance = ![\frac{169560}{230000000}](https://tex.z-dn.net/?f=%5Cfrac%7B169560%7D%7B230000000%7D)
distance = 0.00073721 light year/year
and we know 1 year = 8760 hours
so 1 light year = 9.46027 ×
km
so
sped of moving is
speed = 0.00073721 × 9.46027 ×
km/hr
speed = 796142.197 km/hr
Answer: (-4,2)
Step-by-step explanation:
you just subtract -3 minus -7 and 8- -6
M is the slope, and that can be found by taking any two points on the graph and dividing the difference in their y-values by the difference in their x-values.
m = 3/2 = 1.5
b is the y-intercept, and is found where the line intercepts the y-axis.
b = 4
y = 1.5x + 4
Answer: 79% probability
Step-by-step explanation:
.17 + .13 + .33 + .16 = .79
.79 x 100 = 79%
