Answer:
11
Step-by-step explanation:
The first term of the geometric sequence is given to be a₀, the common ratio r and the (n+1)th term is aₙ.
Now, the condition is given a₀ =6.7, r=1.9 and aₙ=7804.8.
Therefore, a₀.rⁿ=7804.8 = aₙ
⇒ 6.7(1.9)ⁿ=7804.8
⇒(1.9)ⁿ =1164.89
Now, taking log both sides we get,
⇒n log (1.9) =log (1164.89)
⇒n =log (1164.89)/log(1.9) =10.9999≈11
Therefore, the value of n is 11.
The 2x’s cancel out so you would combine the y’s and the other side of the equal sign to get 6y=30. You would then divide each side of the equal sign by 6 to get y alone, leaving you with y=5. Next, plug in the y to either the top or bottom equation. Plugging it in to the top, you would get 2x+4(5)=22. You would multiply 4 and 5 to then get 2x+20=22. Lastly, subtract 20 from both sides then divide by 2 to get x=1.
The answer is (1,5).
Length and width of arena are 2500 ft and 1100 ft.
Area required by each person , a = 2.5 ft².
Now, area of arena is :
Now , number of people can fit is :
Hence, this is the required solution.
