Find the perimeter of a regular heptagon with consecutive vertices at "A" (-2,-5) and "B" (1,-9)
weqwewe [10]

Answer:

Perimeter is 35 units.

Step-by-step explanation:

A heptagon has 7 equal sides.

Given the length of two consecutive vertices, A(-2-5) and B(1,-9).

We can find the length of AB and multiply by 7.

Recall the distance formula;

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of AB is

|AB|=\sqrt{(-2-1)^2+(-5--9)^2}

|AB|=\sqrt{(-3)^2+(4)^2}

\Rightarrow |AB|=\sqrt{9+16}

\Rightarrow |AB|=\sqrt{25}

\Rightarrow |AB|=5\:units

Therefore the perimeter is 7\times 5=35\:units.

Which of the following sets of inequalities​
Ludmilka [50]

Inequalities help us to compare two unequal expressions. The correct options are 2 and 3.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The inequality for the red portion is,

slope, m = (-2/-4) = 1/2

y-intercept is 2.

y ≤ (1/2)x + 2

The inequality for the blue portion is,
slope, m = (5-0)/(3-0.5) = 2

y-intercept is -1.

y > 2x - 1

Hence, the correct options are 2 and 3.
