Given the points A(-1,-3) and B(5,2). A. Write the equation of the straight line AB. Another line MN is parallel to AB and passe

Alexus [3.1K]

<u>Find slope of AB where A = (-1,-3) and B = (5,2):</u>

$\text {Slope = } \dfrac{Y_2-Y_1}{X_2-X_1}$

$\text {Slope = } \dfrac{2+3}{5+1} = \dfrac{5}{6}$

<u>Write equation with the slope found:</u>

$y = mx + b$

$y = \dfrac{5}{6} x + b$

<u>Find y-intercept:</u>

$y = \dfrac{5}{6} x + b$

$2 = \dfrac{5}{6} (5) + b$

$2 = \dfrac{25}{6} + b$

$b = 2 - \dfrac{25}{6}$

$b = -\dfrac{13}{6}$

<u>Form the equation:</u>

$y = \dfrac{5}{6} x - \dfrac{13}{6}$

$\boxed {\boxed {\bf \text {Answer: Line AB : }y = \dfrac{5}{6} x - \dfrac{13}{6}}}$

<u>

A cylindrical trash can is 30 inches high and has a base radius of 7 inches. What is the outside surface area of this trash can,

Paladinen [302]

Answer:

The answer to your question is: A = 1627.35 in²

Step-by-step explanation:

Data

height = 30 in

radius = 7 in

A = ?

Lateral area

A = 2πrh

A = 2(3.1416)(7)(30) = 1319.47 in²

Area of the base and lid

A = 2 x πr² = 2(3.1416)(7)²

= 307.88 in²

At = 1319.47 in² + 307.88 in² = 1627.35 in²

Given the measure of an interior angle of a regular polygon, how many sides does the polygon have?

Elis [28]

The sides of a regular polygon with a known interior angles can be found as follows:

Interior Angle = (n−2) × 180° / n

<h3 /><h3 /><h3>Regular polygon</h3>

A regular polygon is a polygon that have equal sides and equal angles.

A regular polygon has the following angles:

interior angles
exterior angles

According to the question, the interior angles are given. To know the number of sides of polygon can be calculated as follows:

Note the interior and the exterior angles add up to 180 degrees.

Therefore,

Interior Angle = 180° − Exterior Angle

Exterior angle = 360°/n

Interior Angle = 180° − 360°/n

n = number of sides

Finally,

Interior angle = (n−2) × 180° / n
