Part A

we have that

A(4) ----> looking at the graph

A(4) means----> population in the year 1994

so

A(4)----> less than 2 million

and

B(4) -----> greater than 2 million

therefore

the answer Part a is option B

Part B

there is only one value of t where A(t)=B(t)

the value of t is 6 (the year 1996)

Harlamova29_29 [7]

It is easier to understand the problem if you create a number based on the criteria and then perform the computations. I am going to choose: 111 22 33 4

There are 10 options for the first "1" and only 1 option for the other two 1's

There are 9 remaining options for the first "2" and only 1 option for the other 2

There are 8 remaining options for the first "3" and only 1 option for the other 3

There are 7 remaining options for the "4"

10 x 1 x 1    x      9 x 1     x      8 x 1      x      7

10 x 9 x 8 x 7 = 5,040

A triangle has vertices at (-2,-3),(4, -3), and (3,5). What is the area of the triangle?
Bezzdna [24]

Answer:

this triangle is ABC with A(-2 ; -3), B(4; - 3) and C(3;5)

=> AB=\sqrt{(4-(-2))^{2}+\sqrt{(-3 -(-3))^{2} }  }=\sqrt{6^{2} }=6\\\\AC=\sqrt{(3-(-2))^{2}+(5-(-3))^{2}  }=\sqrt{5^{2}+8^{2}  }=\sqrt{89}\\\\BC =\sqrt{1^{2}+8^{2}  }=\sqrt{65}

using Heron theorem, we have:

S=\sqrt{p(p-AB)(p-AC)(p-BC)}\\\\S=\sqrt{(\frac{6+\sqrt{89}+\sqrt{65} }{2})(\frac{\sqrt{89}+\sqrt{65}-6  }{2} )(\frac{6+\sqrt{65}-\sqrt{89}  }{2})(\frac{6+\sqrt{89}-\sqrt{65}  }{2})   }\\\\S=24  \\\\

with S is the area of the triangle

       p=\frac{AB+AC+BC}{2}=\frac{6+\sqrt{89}+\sqrt{65}  }{2}
