Suppose f(x) varies directly with x and f(x) = 24 when x = 2. what is the value of f(x) when x = 6? 1/12 1/2 48 72

D

Step-by-step explanation:

varies directly means

Solve for k:

                     12 = k

Next, input the k-value above and solve for f(x):

f(x) = 72

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer is c 150
