If c varies directly as the square root of d, and c=14, when d = 64, find c when d= 324

c = 31.5

Step-by-step explanation:

Given c varies directly as then the equation relating them is

c = k ← k is the constant of variation

To find k use the condition c = 14 when d = 64, then

14 = k × = 8k ( divide both sides by 8 )

1.75 = k

c = 1.75 ← equation of variation

When d = 324 , then

c = 1.75 × = 1.75 × 18 = 31.5

step-by-step explanation:

it works trust me

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
