The answer is : a^2=1 x 2^n-1
To check if it’s correct
a^2= 1 x 2^2-1
a^2 = 1x 2
a^2 = 2
Hope this helps!
Answer:
slope =
Step-by-step explanation:
Select any 2 ordered pairs from the given table, the use the slope formula to calculate the slope m
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (4, 10) ← 2 ordered pairs from table
m = =
The double angle formula for the sine is
The right hand side is exactly your expression, where
So, rewriting the expression from right to left, we have
