Using the general recursive formula, he 25-th term in the arithmetic sequence is 29.7
<h3>
How to find the value of a₂₅?</h3>
Here we have an arithmetic sequence with the first term a₁ = 3.3 and the common difference is d = 1.1
Remember that the general arithmetic recursive formula is:
aₙ = a₁ + (n - 1)*d
This formula allows us to find the n-th term of the arithmetic sequence only using the first term and the common difference.
In this case, we just need to replace n by 25 and the values written above.
a₂₅ = 3.3 + (25 - 1)*1.1 = 29.7
We can conclude that the 25th term in the sequence is 29.7

Answer:
In the first row, there are 30 seats.
In the the second row, there are 30 seats.
In the third row there are 30 seats.
In the twenty-fifth row, there are 30 seats.
The answer is 25*30 = 750 seats
Step-by-step explanation:
Answer:
25/3 ft/s
Step-by-step explanation:
Height of pole , h=15 ft
Height of man, h'=6 ft
Let BD=x
BE=y
DE=BE-BD=y-x
All right triangles are similar
When two triangles are similar then the ratio of their corresponding sides are equal.
Therefore,
Differentiate w.r.t t
We have dx/dt=5ft/s
Using the value
Hence, the tip of his shadow moving with a speed 25/3 ft/s when he is 45 feet from the pole.
