Answer:
The percentage increase in bird population in the second years is 4% .
Step-by-step explanation:
Given as :
During two years, the population of birds of an island became 7 times more than before.
The the percentage increase in first year = =
=40%
Let The percentage increase in second year =
= r%
So, According to question
The initial population of bird = x
The increase population of bird =7 times before = 7 x
Now,
The increase population of bird = initial population of bird × (1+
) × (1+
)
Or, 7 x = x × (1+
) × (1+
)
Or,
= 1.4 × (1+
)
Or, 7 = 1.4 × (1+
)
Or,
= (1+
)
Or, 5 = (1+
)
Or, (1+
) = 5
Or,
= 5 - 1
Or,
= 4
∴ r = 4 × 100
I.e r = 400
so, The percentage increase = r% = 4
Hence The percentage increase in bird population in the second years is 4% . Answer
Answer:
nth term = (1/6)(6)^(n-1).
Step-by-step explanation:
The first term a1 = 1/6 and the common ratio r = 1 / 1/6 = 6, also 36/6 = 6 which confirms this.
So the nth term = a1 r^(n - 1)
= (1/6) 6^(n-1).

<u>Answer:</u>
When Anne pushes the wheelbarrow 25 meters the work done is 1120 joules
<u>Solution:</u>
We know 
Anne is pushing the wheelbarrow with a force of 70 N at an angle of
with the horizontal
So the force of Anne will be 
She pushes the wheelbarrow 25 meter, So D = 25 meters
So, the 
Anne has done total 1120 joules work.
