Answer:
Angle of elevation
Step-by-step explanation:
An angle measured from the horizontal upwards is an angle of elevation.
An angle measured from the horizontal downwards is an angle of depression.
∠ 2 is a measure from the horizontal upwards thus angle of elevation.
Note that ∠ 3 is an angle of depression
2/3 IS GREATER SO THEREFORE YOUR ANSWER WOULD BE '>'
Answer:
AUB = {E1, E2, E4, E6, E7}
Step-by-step explanation:
Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.
AUB = {E1, E2, E4, E6, E7}
Note that the way you arrange does not matter as well.
I hope you find this solution useful?
Answer:
Step-by-step explanation:
Given that a rock is thrown vertically upward from the surface of an airless planet. It reaches a height of 
where t is expressed in seconds
The rock goes upto a height where the velocity becomes 0 and then it starts falling down by gravity
Velocity at time t = s'(t) = 
This becomes 0 when t =15 seconds
Hence at 15th second the rock starts falling and upto
s(15) = 
metres high it goes
The time taken to reach highest point is = 15 seconds.
Answer: There are 24 pieces of silverware in all.
Step-by-step explanation:
