A chef uses 4 3/4 cups of broth for 10 servings of soup. How much broth used in each serving of soup? Let x represent the number
kozerog [31]
Answer: 0.475 cups of broth per serving.

Explanation:


1) Ratio given:

 i) To facilitate the operations, transform the mixed number 4 3/4 cups into improper fraction:

4 + 3/4 = [16 + 3] / 4 = 19 / 4

ii) ratio broth: servings

\frac{ \frac{19}{4}cups }{10servings}

2) Proportion with the unknown number of cups of broth per serving:

\frac{ \frac{19}{4}cups }{10servings}= \frac{x}{1serving}

3) Solve for the unknown:

x = [19 / 4] cups × 1 serving / 10 servings = 19 / 40 cups = 0.475 cups

Consider the following functions. f1(x) = x, f2(x) = x2, f3(x) = 2x − 4x2 g(x) = c1f1(x) + c2f2(x) + c3f3(x) Solve for c1, c2, a

Answer:

  • (c1, c2, c3) = (-2t, 4t, t) . . . . for any value of t
  • NOT linearly independent

Step-by-step explanation:

We want ...

  c1·f1(x) +c2·f2(x) +c3·f3(x) = g(x) ≡ 0

Substituting for the fn function values, we have ...

  c1·x +c2·x² +c3·(2x -4x²) ≡ 0

This resolves to two equations:

  x(c1 +2c3) = 0

  x²(c2 -4c3) = 0

These have an infinite set of solutions:

  c1 = -2c3

  c2 = 4c3

Then for any parameter t, including the "trivial" t=0, ...

  (c1, c2, c3) = (-2t, 4t, t)

__

f1, f2, f3 are NOT linearly independent. (If they were, there would be only one solution making g(x) ≡ 0.)
