2. If x is directly proportional to y^3 and x=32 when y=2, i) Find an equation
svp [43]

Answer:

(i)

x \alpha y {3} \\ \frac{x}{y {3} }  = k

(ii)

\frac{x}{y {3}^{} }  =  \frac{x}{y {3}^{} }  \\  \frac{32}{ {2}^{3} }  =  \frac{x}{6 {}^{3} }  \\  \frac{32}{8}  =  \frac{x}{216} \\ x = 864

(iii)

\frac{32}{8}  =  \frac{108}{y {}^{3} }  \\   {y}^{3 }  = 27 \\ y =  \sqrt[3]{27 }  \\ y = 3

What characteristics best describe the graph? Choose all that apply. *
marin [14]

Answer:

Options (1), (3) and (7)

Step-by-step explanation:

Characteristics of the given graph are as followed.

1). For every input value (x-value) there is a different output values (y-values).

   So the points on the graph represent a function.

2). Coordinates of all the points are distinct and separate (not in fractions or decimals).

    Function given is a discrete function.

3). For every increase in the x-values of the points there is a decrease in y-values.

  Therefore, given function is a decreasing function.

Therefore, Options (1), (3) and (7) are the correct options.
