You need to find the distance between the 3 lengths of the lines from the given points
ef = sqrt ( 6-4) ^2 + 2-2^2) = sqrt 4 = 2
fg = sqrt (6 - 2)^2 + 4-4^2 = sqrt16 = 4
ge = sqrt (6-4)^2 + (2-6)^2) = sqrt 20 = 4.47
circumference = 2 + 4 + 4.47 = 10.47
Answer:
t=10 s
Step-by-step explanation:
v=u+gt
108=10+9.8t
108-10=9.8t
9.8t=98
Scientific notation has 1 number to the left of the decimal and is multiplied by 10 raised to the number of spaces the decimal is moved.
A) 5.9 x 10 ^ 9
B) 4 x 10 ^ -2
C) 1 km = 100,000 cm
4x 10^-2 x 100,000 = 4000 fireflies per km = 4 x 10 ^3 fireflies per km
5.9x 10^9 x 4x 10 ^3 = 2.4 X 10^13
