It MUST be a right triangle for this formula to work, please comment if it is not a RIGHT triangle

a and b being the lengths of the legs of the triangle (the 2 sides that are not the hypotenuse) and c being the hypotenuse's length.
The correct answer is d, to solve for r divide both sides by 2piH
Answer:
aₙ = -2aₙ₊₁
Step-by-step explanation:
According to the sequence given 16, -8, 4, ...
a1 = 16
a2 = -8
a3 = 4
From the values, we can conclude thst;
a1 = -2(-8)
Since a2 = -8, then;
a1 = -2(a2)
Similarly
a2 = -2(4)
a2 = -2a3
The subsequent sequence are;
a3 = -2a4
The nth term will ne;
aₙ = -2aₙ₊₁
Hence the required recursive function is aₙ = -2aₙ₊₁
Answer:
there are 4.3 weeks in a month
so then,
4.3 × 70 = 301
the awnser is:
301 dollors per month
