Given:2009 : 3,500 populationdecrease 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. add me as da brainliest
Find the solution set of x: x^2-7x= - 10.
Answer:
(x − 2)(x −5)
Step-by-step explanation:
x² - 7x = - 10
x² - 7x + 10 = 0
Find two numbers that when added together make −7 , and when multiplied make - 10.
The numbers − 2 and −5 fit the criteria.
x2− 7x + 10 = (x − 2)(x −5)
Answer:
7986 m²
Step-by-step explanation:
The figure is a trapezium with area (A) calculated as
A = 
h (a + b)
where h is the height and a, b the parallel bases
Here h = 66, a = 102 and b = 140, thus
A = × 66 × (102 + 140) = 33 × 242 = 7986 m²
