I guess I'm lacking in differential equations. I couldn't solve this question. Can you help me?

Sonja [21]

Answer:

See Explanation.

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

Reciprocals

<u>Algebra II</u>

Log/Ln Property: $ln(\frac{a}{b} ) = ln(a) - ln(b)$

<u>Calculus</u>

Derivatives

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Derivative of Ln: $\frac{d}{dx} [ln(u)] = \frac{u'}{u}$

Step-by-step explanation:

<u>Step 1: Define</u>

$ln(\frac{2x-1}{x-1} )=t$

<u>Step 2: Differentiate</u>

Rewrite: $t = ln(\frac{2x-1}{x-1})$
Rewrite [Ln Properties]: $t = ln(2x-1) - ln(x - 1)$
Differentiate [Ln/Chain Rule/Basic Power Rule]: $\frac{dt}{dx} = \frac{1}{2x-1} \cdot 2 - \frac{1}{x-1} \cdot 1$
Simplify: $\frac{dt}{dx} = \frac{2}{2x-1} - \frac{1}{x-1}$
Rewrite: $\frac{dt}{dx} = \frac{2(x-1)}{(2x-1)(x-1)} - \frac{2x-1}{(2x-1)(x-1)}$
Combine: $\frac{dt}{dx} = \frac{-1}{(2x-1)(x-1)}$
Reciprocate: $\frac{dx}{dt} = -(2x-1)(x-1)$
Distribute: $\frac{dx}{dt} = (1-2x)(x-1)$

Which inequality is used to find the domain<br>

Igoryamba

<h3>Answer: Choice D. $5x-5 \ge 0$ </h3>

This is because we want to avoid having negative numbers under the square root. So we make the radicand to be 0 or larger.

The +1 at the end doesn't affect the domain.

You want to buy some rice. A 7-ounce package costs 2.59. A 12- ounce package costs $4.56. An 18-ounce package costs 6.30 which p

Reika [66]

Type 1 rice :

7-ounce package costs = 2.59.

Cost of 1-ounce of Type 1 rice= 2.59/7 = $0.37

Type 2 rice :

12-ounce package costs = $4.56

Cost of 1-ounce Type 2 rice = 4.56/12 = $0.38

Type 3 rice :

18-ounce package costs = $ 6.30

Cost of 1-ounce Type 3 rice = 6.30/18 = $0.35.

From the above calculations, we can see that the cost of 1-ounce Type 3 rice is lowest. Therefore, 18-ounce package is Best Buy.
