Answer:
The maximum height that the ball reaches is sf = 31 feet from the ground
Step-by-step explanation:
Solution:-
- A ball is thrown vertically upwards from an initial elevation of si = 6 feet from the ground.
- The velocity with which the ball was thrown up, vi = 40 ft/s
- We can determine the maximum height of the ball when it is thrown vertically up by using the 3rd kinematic equation of motion.
vf^2 - vi^2 = 2*g*( sf - si )
Where,
vf : The final velocity of the ball, for maximum height it is = 0
sf : The final height of the ball from the ground
g : Gravitational constant = -32 ft/s^2
0 - 40^2 = -2*32*( sf - 6 )
sf - 6 = 25
sf = 31 feet
- The maximum height that the ball reaches is sf = 31 feet from the ground.
Answer:
I think that the first one is not a rhombus but the last two are.
Answer:
1. One way to show that a statement is not a good definition is to find a counterexample. A counterexample refers to an exception to the rule, if we deduct that exception is true, then the proposition is completely false. In this case, we have to find an exception to the definition, if the exception is true, then the definition is not true.
2. The option that show a true conditional is the fourth: If it's raining, then the humidity level is 100%. This shows the correct logical conditional, other options are not logical. In this case, the hypothesis is "if it's raining", and the conclusion is "the humidity is 100%". This is the right order, because humidity derive from raining, not the opposite.
The true conditional with a correctly identified hypothesis is:
If it is raining, then the humidity level is 100%.
Hypothesis: It is raining.
Conclusion: The humidity level is 100%.
1. One way to show that a statement isn't a good description is to find a counterexample.
A counterexample refers to an exception to the rule, if we abate that exception is true, also the proposition is fully false. In this case, we've to find an exception to the description, if the exception is true, also the description isn't true.
2. The option that show a true tentative is the fourth If it's raining, also the moisture position is 100.
This shows the correct logical tentative, other options aren't logical. In this case, the thesis is" if it's raining", and the conclusion is" the moisture is 100". This is the right order, because moisture decide from raining, not the contrary.
