f(x) = 3/(x + 2) - √x - 3
f(7) = 3/(7 + 2) - √7 - 3
f(7) = 3/9 - √4
f(7) = 0.333 - 2
f(7) = -1.67
Answer:
1) 3*0.7 = 2.1 pounds
2) 3.7*3.9 = 14.43 miles long
3) 20.64/2 = $10.32 each
4) (2*13.75)/(5+6) = $2.50 each
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
