To the nearest tenth, find the perimeter of ∆ABC with vertices A(-1,4), B(-2,1) and C(2,1).
swat32

First we need to find the length of each side of the triangle , and for that we need to use the distance formula, that is
d =\sqrt{(x_{2} -x_{1})^2 +(y_{2} -y_{1})^2}
AB = \sqrt{(1-4)^2 +(-2+1)^2}= \sqrt{10}
\sqrt{BC} = \sqrt{(1-1)^2 + (2+2)^2}=4
Perimeter is the sum of all sides.
Perimeter = AB + BC + AC = \sqrt{10}+4 +\sqrt{18}
Perimeter= 11.4

Suppose the first term of a geometric sequence is 3 and the fourth term is 192. What is the common ratio of the sequence? Write
gayaneshka [121]
An=A1 r ^(n-1)
192= 3 r ^(4-1)
192 = 3 r^3
64 = r^3
r = 4

equation:
An=3 (4)^(n-1)

6th term:
An= 3 (4)^(6-1)
An= 3072

I think this is right :)
