He should change the coefficient 5
Answer:
work = force × distance
Therefore,
work = 3200N × 16m
= 51200J
So,
Power = Work done/ time taken
Therefore,
Power = 51200/30
= 1706.6 ~ 1707W
Hope it helps!
Answer:
First rationalize the surd
(√3 +√2)(√3 - √2)/(√3 - √2)(√3 -√2)
The final answer will be 5 + 2√6
So x = 5 + 2√6
I) x + 1/x
5 + 2√6 + 1/5 + 2√6
Find the LCM
The final answer will be 10
ii) x² +1/x²
(5 + 2√6)² + 1/(5 +2√6)²
= 49 + 20√6 + 1/49 + 20√6
Find the LCM
The final answer will be 98
For i) x = 10
ii) x = 98
Hope this helps.
5 coin tosses. This means,
Total observations =25=25
Required outcome → 5 Heads {H,H,H,H,H}
This can occur only ONCE!
Thus, required outcome =1=1
Probability (5 Heads) =125=132
i DON;T KNOW MAYBE 10+9=21 is the correct answer. let me know if it right! hope u have a grate day
