First we will do the plus sign for 2.
19 + 2 + 1 + 4 + 2 - 10
Add then subtract.
19 + 2 + 1 + 4 + 2 = 28
28 - 10 = 18.
Now we will do the negative sign for 2.
19 - 2 + 1 + 2 + 4 + 2 - 10
19 + 1 + 2 + 4 + 2 = 28
28 - 2 = 26 - 10 = 16.
Answer is 16 and 18.
Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
Answer: 1)100ways and 2)90ways
Step-by-step explanation:
Given :-The 10 students who completed a special flying course are waiting to see if they will be awarded the one Distinction or the one Merit award for their efforts.
Ways can the two awards be given if the same student can receive both awards (i.e repetition is allowed)
=10×10=100ways
Ways can the two awards be given if the same student cannot receive both awards(i.e. repetition is not allowed)
=10×9=90ways
