The square of a prime number is not prime.
a) let x ∈ R, If x ∈ {prime numbers}, then
∉{prime numbers}
there says that if x is a real and x is in the set of the prime numbers, then the square of x isn't in the set of prime numbers.
b) Prove or disprove the statement.
ok, if x is a prime number, then x only can be divided by himself. Now is easy to see that
= x*x can be divided by himself and x, then x*x is not a prime number, because can be divided by another number different than himself
I believe the answer is C. If you were to plug in 1 for t, you would get h=22. Thus, the max height is 22 feet, and the time it took to get there was 1 second.
It’s a black picture can’t see
If the Height of Eiffel Tower in Paris is 1063 feet tall and we took an elevator 3/4 up the tower then we would be 797.25 feet from the ground.
Given The height of the Eiffel Tower is 1063 feet tall. We have taken an elevator that is 3/4 up the tower.
Height is the measurement of someone from head to foot or from base to top. It is the distance upward.
Height of The Eiffel tower is 1063 feet.
We have taken 3/4 up the elevator.
Then the height from ground to us can be calculated by multiplying 1063 by 3/4 which will be as under:
=1063*3/4
=729.25 feet
Hence if the height of the Eiffel Tower is 1063 feet then we would be 729.25 up from the ground if we have taken elevator 3/4 up the tower.
