Given:
2009 : 3,500 population
decrease of 2.2% per year.
100% - 2.2% = 97.8%
2014 - 2009 = 5 years
3,500 * (0.978)^5 = 3,500 * 0.89473 = 3131.57
The bird population in 2014 will be 3,131.57 or 3,132.
Answer:
The third term is 11.
The first negative term is the fifth term.
Step-by-step explanation:
If the nth term of the sequence is given by the expression 20-n^2, to find the third term, we just need to use the value of n = 3 in the expression:
20 - (3)^2 = 20 - 9 = 11.
To find which term is the first to have a negative value, we can solve the inequation 20 - n^2 < 0:
20 - n^2 < 0
n^2 > 20
n > 4.47
The first term to have a negative value is the fifth term:
20 - 5^2 = 20 - 25 = -5
Length x width = area
width=x
length=2x
2x*x=50
2x^2=50
x^2=25
x=5
width=5
length=2x5=10
Answer:
Step-by-step explanation:
x^2 + 17x + 60
(x + 12)(x + 5)
Arc length = radius* angle
Solving for angle
---> angle = ArcLength/radius
