This is false. If we assumed the prime numbers were closed under subtraction, then the difference of any two primes would also get us a prime number.
Take the prime numbers 11 and 7. Their difference, 11 - 7, is 4, but 4 is composite, as it has 2 as a factor other than 1 and 4. All we need is this one counterexample to prove that prime numbers are <em>not </em>closed under subtraction.
The answer is (1 3/4, 8 1/4)
This is because if you check the previous values for x and y you can see that you have to add 2/4 to c and y.
Hope this helps!
If it does, it would be helpful to me if you could make me brainliest.
Answer: Option 'C' is correct.
Step-by-step explanation:
Debit card issued by a particular bank can be used to point of sales transactions and ATM withdrawal too.
As functions of Debit Card are :
1) Point of sales transactions whenever you don't have cash with yourselves, then, we can use debit card.
2) For ATM withdrawals, we can use debit card, whenever we need a cash.
Hence, Option 'C' is correct.
First you get the length PX
secondly you use the sine rule a\sin A= b\sin B=c\sin C
hence hy = 30
you take 30\sin 90=18\X
cross multiply
sin 90 × 18 = 30×X
sin 90 = 1
1×18=30X
18\30=30X\30
0.6=X
then sin~1 0.6
answer 36.8699 as angle p
then get cos 36.8699
