Answer:
10 meters
Step-by-step explanation:
The given function
represents the height,
, in meters,
seconds after the ball is thrown.
Since the ball is thrown off the roof, then ball's height will be equal to the roof's height before being thrown (0 seconds). Therefore, substitute
into the given function
:

Therefore, the building is 10 meters tall.
To answer this question you will find the means and the mean absolute deviations and compare them.
The correct answers are
A and C.
Please see the attached picture for the organized work.
3.55 because three is greater than two
Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
=
= 180°
= 180° -------(1)
And 
180° = 40° + 
= 140°
Since, 
= 140° [Given
]
= 70°
From equation (1),
= 180° - 
= 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
