Answer:
7
Step-by-step explanation:
In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*

= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
Answer:
58,900cm²
Step-by-step explanation:
Area of the triangle = 1/2absin thets
Area of the triangle = 1/2* i * j sin 30
Area of the triangle = 1/2 * 380 * 620 sin 30
Area of the triangle = 380 * 310 * 0.5
Area of the triangle = 380*155
Area of the triangle = 58,900cm²
hence the area of the triangle is 58,900cm²
The answer is DDDD, because if you plug in all the values of x and y into the equation like this..
y=x-3
A - 5=-2-3 >> 5=-5 >> not correct
B 2= -5-3 >> 2=-8 >> not correct
C 5=2-3 >> 5=-1 >> not correct
D 2=5-3 >> 2=2 >> CORRECT
D is the only correct answer!
