Answer: -0.5.

Step-by-step explanation:

The constant of variation k for the direct variation is given by:-

k= \dfrac{f(x_2)}{x_2}=\dfrac{f(x_1)}{x_1}

The given table:

x  f( x )

0   0

2   -1

4    -2

7   -3.5

Then,

k=\dfrac{-1}{2}=\dfrac{-2}{4}=\dfrac{7}{-3.5}=-0.5

Hence, the constant of variation k for the direct variation is -0.5.

Sergio039 [100]

Answer:

f(3/2)= 5√5

Step-by-step explanation:

f(3/2)= (5^3)^1/2  is the same things

f(3/2)= (125)^1/2 fraction exponent are the same are roots ^(1/2) is √

f(3/2)= √125

f(3/2)= √25 times √5 break up 125 to be 25 x 5

f(3/2)= 5√5 because √25 = 5 and √5 stays as √5
