Answer:
Step-by-step explanation:
f(x) = 1/2(4)^x
Plug in 3 for x
f(3) = 1/2(4)³
Cube 4.
4³ = 4 x 4 x 4 = 64
f(3) = 1/2(64)
Multiply 64 with 1/2 (or divide by 2)
f(3) = 64/2
f(3) = 32
You have to multiple 3.14 time the diameter
3.14*15
47.1
3. Trapezoid- only one pair of parallel sides
4. Parallelogram- opposite sides are parallel and equal in length and opposite angles are equal
5. Rhombus- all sides have an equal length, opposite sides are parallel, and opposite angles are equal
6. Kite- have two pairs of sides, each made up of adjacent sides that are equal in length. Angles are equal where pairs meet.
7. Isosceles Trapezoid- have a pair of opposite parallel sides that are equal in length.
The answer is going to be 4. hope that helped
