A^2 + b^2 = c^2

a^2 + (12)^2 = (13)^2

a^2 + 144 = 169

a^2 = 169 - 144

a^2 = 25

Sqrt (a^2) = Sqrt(25)

a = 5

Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain.
djyliett [7]
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one


so
when n=1, an=40
so a1=40
it seems to increas by 7 each time

an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula

the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term

domain is natural numbers
the formula is a_n=33+7n or a_n=7n+33

a sixth grade class has 12 boys and 24 girls consider this statement for every 2 boys there are 4 girls do you agree with this s
tigry1 [53]

This statement is correct as 12 is half of 24 and 2 is half of 4. We can also put this as the fraction 1/2 or 0.5 or 50% or 1:2. Therefore for every one bot there are two girls in the class.
