Answer:

Step-by-step explanation:

slope m = (y₂ - y₁)/(x₂ - x₁)

= 6-6 / 8 - (-5) = 0/ 8+5 = o

Slope = o. ie the line is parallel to the x-axis.

When beans are cooked, the amount of water required varies directly with the cups of beans. If 2 cups of beans require 4.5 cups

marishachu [46]

Answer:

11.25 cups of water is needed to cook 5 cups of Beans.

Step-by-step explanation:

Given:

The amount of water required varies directly with the cups of beans.

2 cups of beans require 4.5 cups of water.

we need to find how many cups of water are needed to prepare 5 cups of beans.

4.5 cups of water =2 cups of bean

Number of cups of water = 5 cups of bean.

Now Using Unitary method for solving above we get,

Number of cups of water required = $\frac{5\times4.5}{2}=\frac{22.5}{2}=11.25 \ cups$

Hence 11.25 cups of water is required to prepare 5 cups of beans.

By using algebra properties and trigonometric formulas we find that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equivalent to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ .

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>

In this question we have trigonometric expression whose equivalence to another expression has to be proved by using algebra properties and trigonometric formulas, including the fundamental trigonometric formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:

$\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ Given.

$\frac{1 + \sin x - 1 + \sin x}{1 - \sin^{2}x}$ Subtraction between fractions with different denominator / (- 1) · a = - a.

$\frac{2\cdot \sin x}{\cos^{2}x}$ Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)

$\frac{2\cdot \tan x}{\cos x}$ Definition of tangent / Result

By using algebra properties and trigonometric formulas we conclude that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equal to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ . Hence, the former expression is equivalent to the latter one.
