Answer:
Step-by-step explanation:
We are in the case of vertical shot. If we neglect air resistance, the only force acting over the ball is gravity. As gravity acts down to earth and the ball is going up, speed´s ball will be decreasing by gravity ( 9.8 m/sec²) That means the speed of the ball will be decreasing 9.8 m/sec, each second.
When the ball get the maximum height Vy = 0 then the ball stars descending, and when the ball is descending again gravity is the only force acting gravity acts in the same direction as the ball´s movement, so the ball´s speed will increase at a rate of 9.8 m/sec each second.
It is a well known fact that the time of the ball to get maximum height is the same as for the ball to fall down to earth. In other words time from the beginning of the movement up to maximum height is equal to time for the ball to fall down.
Answer:
Step-by-step explanation:
- Initial value = $0.03
- Increase rate = 2 times each day
- Time = 30 days
<u>Saving amount after 30 days:</u>
- $0.03*2^30 = $32212254.72
The properties or relationship between the angles m∠1, m∠2, and m∠3 can be used to determine the statement that must be true
The correct option that gives the statement that must be true to prove that m∠1 + m∠2 + m∠3 = 180°, is the first option
A. m ║ n
Reason:
Which statement must be true to prove that m∠1 + m∠2 + m∠3 = 180°?
A. m ║ n
B. m∠1 + m∠2 = 180° - m∠3
C. m∠1 + m∠2 = 90°
D. m∠1 = m∠2 = m∠3
Given that m∠1 + m∠2 + m∠3 = 180°, we have;
m∠ACD + m∠2 + m∠3 = 180° by angles on a straight line
Therefore;
m∠ACD = m∠1 by addition property of equality
m∠ACD ≅ m∠1 by definition of congruency
m∠ACD and m∠1 are alternate interior angles formed between lines <em>m</em> and <em>n</em> and their common transversal AC
Which gives;
<em>m</em> ║ <em>n</em>, by alternate interior angles theorem which states that alternate interior formed between parallel lines are congruent
Therefore;
The statement that must be true to prove that m∠1 + m∠2 + m∠3 = 180° is <u><em>m</em></u><u> ║ </u><u><em>n</em></u>

Answer:
6in
Step-by-step explanation:
The volume of a spherical balloon is 4/3 π R^3.
So 288π = 4/3 π R^3
The factors of π cancel out. Divide both sides by 4/3 to get:
216 cubic inches = R^3
Take the cube root of both sides, and you find that R = 6 inches
Answer:
The answer is false
Step-by-step explanation:
" An event is certain if its probability is 100% "
Statistics is about probability of occuring of an event; you cannot buy 100% certainty. Statistics is about managing risk.
Hence the following given statement is not correct that: In statistics, results are always reported with 100% certainty.
Hence the statement is FALSE.
