The same sequence may be defined in three ways: 1) f(x) = 5x + 1 for x = {1, 2, 3, ...}, 2) a1 = 6 and an + 1 = (an)(5) for n = {1, 2, 3, ...} and 3) an = 6 + 5(n − 1) for n = {1, 2, 3, ...}. They are all supposed to generate the same values, but one version may contain an error. If one version contains an error, identify the one with the error and fix it. A) None of these have errors, they all generate the same sequence. B) f(x) = 5x + 1 for x = {1, 2, 3, ...} It should say f(x) = 1x + 5 for x = {1, 2, 3, ...}. C) an = 6 + 5(n − 1) for n = {1, 2, 3, ...} It should say an = 5 + 6(n − 1) for n = {1, 2, 3, ...}. D) a1 = 6 and an + 1 = (an)(5) for n = {1, 2, 3, ...} It should say a1 = 6 and an + 1 = an + 5 for n = {1, 2, 3, ...}.

D) and for n = {1,2,3...}

It should say and for n = {1,2,3...}

Step-by-step explanation:

nope lol

step-by-step explanation:

tell you what. i'll find the length of the medians and you can fill in the blanks where they belong.

br

b = (2a,0)

r = (a/2,b/2) remember these things are medians. they go to the 1/2 way point of the line opposite the vertex they face.

br^2 =   (2a - a/2)^2 + (0 - b/2)^2

br^2 = (3/2 a) ^2 + b^2 / 4

br^2 = 9/4 a^2 + b^2 / 4   we need to find some relationship between a and b.

let's try ab = bc  

ab = 2a

bc = (2a - a)^2 + (b - 0)^2

bc = sqrt(a^2 + b^2)

ab = bc

2a = sqrt(a^2 + b^2) square both sides.

4a^2 = a^2 + b^2 subtract a^2 from both sides.

sqrt(3a^2) = sqrt(b^2)

sqrt(3)a = b

let's put b into br^2

br^2 = 9/4 a^2 + 3b^2 / 4

br^2 = 12 a^2 / 4

br^2 = 3a^2 

br = sqrt(3) * a

cp

c = (a,b) ; p = (a,0) this is another application of the distance formula, and it is a good one.

cp^2 = (a - a)^2 + (b - 0)^2

cp^2 = 0 + b^2

cp^2 = b^2 which you can see from the diagram. 

cp = sqrt(b^2)

cp = b but b = sqrt(3) * a 

cp = sqrt(3)*a

aq

a = (0,0)

q = (3/2) a, b/2

aq^2 = (3a/2 -0)^2 + (b/2 - 0)^2

aq^2 = 9a^2/4 + b^2/4

but b = sqrt(3) * a 

aq^2 = 9a^2 / 4 + (sqrt(3)*a)^2 /4

aq^2 = 9 a^2/ 4 + 3 a^2 / 4

aq^2 = 12 a^2/4

aq^2 = 3 a^2

aq = (sqrt  3) * a which agrees with the other two.
