Nostrana [21]2 years ago
5 0

Answer:

=0.7f−5.84

Step-by-step explanation:

Let's simplify step-by-step.

f(0.7)−6.32−0.8+1.28

=0.7f+−6.32+−0.8+1.28

Combine Like Terms:

=0.7f+−6.32+−0.8+1.28

=(0.7f)+(−6.32+−0.8+1.28)

=0.7f+−5.84

Answer:

=0.7f−5.84

Write a equation for (-6, -3)
Vlad [161]

<u>Answer</u>:

equation: y = x/2

<u>Explanation</u>:

let the points be  (-6, -3) ,  ( 0, 0)

slope: \frac{y2-y1}{x2-x1}

         : \frac{0--3}{0--6}

         : \frac{1}{2}

Equation using:

y - y1 = m ( x - x1 )

y - - 3 = 1/2( x - - 6 )

y + 3 = x/2 + 3

y\\ = \frac{x}{2}

What is the measure of one angle of a regular convex 20-gon
Contact [7]

Answer:

The measure of one angle of a regular convex 20-gon is 162°

Step-by-step explanation:

* Lets explain how to solve the problem

- A convex polygon is a polygon with all the measures of its interior

 angles less than 180°

- In any polygon the number of its angles equal the number of its sides

- A regular polygon is a polygon that is all angles are equal in measure

 and all sides are equal in length

- The rule of the measure of an angle of a regular polygon is

 m=\frac{(n-2)180}{n}, where m is the measure of each interior

 angle in the polygon and n is the numbers of the sides or the angles

 of the polygon

* Lets solve the problem

- The polygon is convex polygon of 20 sides (20 angles)

- The polygon is regular polygon

∵ The number of the sides of the polygon is 20 sides

∴ n = 20

∵ The polygon is regular

∴ All angles are equal in measures

∵ The measure of each angle is m=\frac{(n-2)180}{n}

∴ m=\frac{(20-2)180}{20}

∴ m=\frac{(18)180}{20}

∴ m=\frac{3240}{20}

∴ m = 162

∴ The measure of one angle of a regular convex 20-gon is 162°
