Answer:
The inequality for this diagram is x≥-1
Please the explanation... it always helpsssss....
Step-by-step explanation:
The first step is to look at the circle... is it filled in or not... in this case it is...
meaning the symbol is greater than or equal to OR less than or equal to
next the arrow is pointing to the right meaning the symbol must be greater than or equal to
then look at the value at the filled in circle (which in this case is -1)
meaning the inequality must be x≥-1
i really hope this helps!!!!
Range = (u^2 * sin of angle) ÷ g
acceleration due to gravity (g) = 9.8m/s
...
R = (u^2 sin 36.9) ÷ 9.8 = (900 * 0.600420225) ÷ 9.8
R = 540 ÷ 9.8 = 55.102 m ...
t = 55 ÷ 30 = 1.833s ... total flight time...
takeoff time and landing time...
tan = opp ÷ adj
tan 36.9 = 10 ÷ adjacent... = 0.750821238 = 10 ÷ a
a = 10 ÷ 0.8 = (10 * 10) ÷ 8 = 12.5m
55.102m = 1.833
12.5m = (12.5 ÷ 55.102) * 1.833 = 0.4158s
1st time = 0.42s ...at takeoff
2nd time = 1.833 - 0.42 = 1.413s ...at landing
Ans = 0.42s ...and 1.41s ...
