Answer:
1.6% growth rate
43.75 years = doubling time.
Explanation:
40-24 = 1616/1000 = 0.016 x 100 = 1.6% growth rate
70/1.6 = 43.75 years = doubling time.
1 million is 1 x 10^6
1 billion is 1 x 10^9
1 trillion is 1 x 10^12
So 12 trillion miles is 12 x 10^12 which converts to 1.2 x 10^1 x 10^12 = 1.2 x 10^13
Answer:
0.447 sec
Explanation:
velocity = distance/ time
distance 'h' is a function of time 't' given by

⇒ differentiating equation
⇒ velocity = 
⇒ acceleration =
= 24 
deceleration due to gravity = -9.8 m/
= - 9.8 x 3.281 = - 32.154 ft/ 
Net deceleration = 24 - 32.154 = - 8.15 ft/
at maximum height v = 0
=
+ 2ah
⇒ 0 =
+ 2 (-8.15)h
⇒ h = 118.72 ft⇒
118.72 = 12
+ 44t + 16
⇒
- 102.72 = 0
⇒ t = -44 ±
/ (2 x 12)
t = 0.447 sec
