(round your
answer to the nearest hundredth)

Step-by-step explanation:

f(x) = 2x^2 + 5(sqrt(x+2))

Simply substiture 0 for x.

f(0) = 2(0)^2 + 5(sqrt(0+2))

f(0) = 0 + 5(1.41421356237)

f(0) = 7.07106781185

Round it to the nearest hundredth.

f(0) = 7.07

Hope this helped!

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
