What is the area of sector AEB when AE = 8 yd? 16π yd2 2π yd2 8π yd2 4π yd2
1 answer:
16π yards²
To make things a little simpler to start off, convert the angle of the sector AEB into radians. It's 90 degrees, which is equivalent to π/2 radians.
Plug π/2 into the formula for finding the area of a sector, along with the value of 8 for r, the radius:
(angle in radians)
When you simplify that down, you get A = 16π so the answer is 16π yards²

Step-by-step explanation:
The exponent rules that apply are ...
(a^b)(a^c) = a^(b+c)
a^-b = (1/a)^b
(a^b)^c = a^(b·c)
_____
These let you rewrite the given function as ...
f(x) = (3^(2x))(3^1) = 3(3^(2x)) = 3(3^2)^x = 3·9^x
and
f(x) = 3^(2x+1) = (3^-1)^(-(2x+1)) = (1/3)^-(2x+1)
