Take a moment to think about what tan(θ) represents.1. Use interval notation to represent the values of θ (between 0 and 2π) whe

Nonamiya [84]

Let's first get the representation of tan

We also need to understand how to convert radians to degrees

$\begin{gathered} \frac{\pi}{2}=90^0 \\ \pi=180^0 \\ \frac{3\pi}{2}=270^0 \\ 2\pi=360^0 \end{gathered}$

For question 1

since tan > 1

It must be in either first quadrant or third quadrant as shown in the diagram above

$\begin{gathered} \text{ } \\ \frac{\pi}{4}$

Find the area of the regular polygon. Round to the nearest tenth. 16 ft

Sladkaya [172]

Given:

Given that the side of the regular polygon is 16 feet.

We need to determine the area of the polygon.

Area of the polygon:

The area of the polygon can be determined using the formula,

$Area =\frac{s^2 n}{4 \ tan \frac{180}{n}}$

where n is the number of sides,

s is the side length.

Substituting n = 3 and s = 16, we get;

$Area =\frac{16^2 (3)}{4 \ tan \frac{180}{3}}$

Simplifying, we get;

$Area =\frac{(256) (3)}{4 \ tan \ 60}$

$Area = \frac{768}{6.928}$

Dividing, we get;

$Area = 110.85$

Rounding off to the nearest tenth, we have;

$Area = 110.9$

Thus, the area of the regular polygon is 110.9 square units.

Solve -3x=2x^2-4 using quadratic formula

frozen [14]

Answer:

$x=-2.35078, 0.850781$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Step-by-step explanation:

Step 1: Define equation

-3x = 2x² - 4

Step 2: Rewrite into Standard Form

0 = 2x² + 3x - 4

Step 3: Define variables

a = 2

b = 3

c = -4

Step 4: Find x

Substitute: $x=\frac{-3\pm\sqrt{3^2-4(2)(-4)} }{2(2)}$
Evaluate: $x=\frac{-3\pm\sqrt{9-4(2)(-4)} }{2(2)}$
Multiply: $x=\frac{-3\pm\sqrt{9+32} }{4}$
Add: $x=\frac{-3\pm\sqrt{41} }{4}$
Evaluate: $x=\frac{-3\pm6.40312}{4}$
Evaluate: $x=-2.35078, 0.850781$

And we have our final answer!
