Answer:

Switch x and y, and solve for y

$f^{-1}(x) =\frac{(x -4)^3}{8}$

Step-by-step explanation:

Given

$f(x) = 3\sqrt{8x} + 4$

Required

Complete the steps to determine the inverse function

Solving (a): Complete the blanks

Switch x and y, and solve for y

Solving (b): Determine the inverse function

$f(x) = \sqrt[3]{8x} + 4$

Replace f(x) with y

$y = \sqrt[3]{8x} + 4$

Switch x and y

$x = \sqrt[3]{8y} + 4$

<u>Now, we solve for y</u>

Subtract 4 from both sides

$x -4= \sqrt[3]{8y} + 4-4$

$x -4= \sqrt[3]{8y}$

Take cube roots of both sides

$(x -4)^3= 8y$

Divide both sides by 8

$\frac{(x -4)^3}{8} = y$

So, we have:

$y =\frac{(x -4)^3}{8}$

Hence, the inverse function is:

$f^{-1}(x) =\frac{(x -4)^3}{8}$

A chef plans to mix 100% vinegar with Italian dressing, The Italian dressing contains 8% Vinegar,

kolezko [41]

Answer:

15 mL of 100% vinegar
45 mL of Italian dressing

Step-by-step explanation:

Let v represent the amount of 100% vinegar to be included in the mixture. Then the amount of vinegar in the overall mixture is ...

1.00v + 0.08(60 -v) = 0.31(60)

0.92v = 60(0.23) . . . . . . . collect terms, subtract .08(60)

v = 60(0.23/0.92) = 15 . . . mL of vinegar

60 -v = 45 . . . mL of dressing

15 mL of vinegar and 45 mL of Italian dressing should be used.
