The value of f(1) = 81
Step-by-step explanation:
For the recursive function, f(n+1) = one-half(n)
Thus, when n = 2,
f(3) = 9
If n = 1,
f(2) = 9×3
f(2) = 27
If n = 0,
f(1) = 27 ×3
f(1) = 81

Answer:
6.50w
Step-by-step explanation:
Given that :
Weight ________ Cost ($)
1 ______________6.50
2 _____________ 13.00
3 _____________ 19.50
Cost of package that weighs w pounds
If one pound = 6.50
2 pounds = 13.0
Then, the cost per pound = $6.50
Hence, cost of package that weighs w pounds will be ;
$6.50 * w = $6.50w
So, πr^2 is the equation for the area of a circle, if we calculate that, it will equal 17662.5
we then half that to get the area (square feet) of the dead grass, which equals 8831.25 square feet, therefore choice B is the answer
