Find the slope of the line through each pair of points (6, -10) , (-15 , 15)

dem82 [27]

<h3><u>Answer:</u></h3>

$\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}$

<h3><u>Step-by-step explanation:</u></h3>

Two points are given to us and we need to find the slope of the line . The slope of the line passing through points $\bf (x_1,y_1 ) \ \& \ (x_2,y_2)$ is given by ,

$\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}$

Here , the points are ,

( 6 , -10 )
( -15 , 15 )

$\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}$

<h3><u>★</u><u> </u><u>Hence </u><u>the</u><u> </u><u>slope</u><u> </u><u>of</u><u> the</u><u> </u><u>line</u><u> </u><u>join</u><u>ing</u><u> </u><u>the </u><u>two</u><u> </u><u>points</u><u> </u><u>is</u><u> </u><u>-</u><u>2</u><u>5</u><u>/</u><u>2</u><u>1</u><u> </u><u>.</u></h3>

Sam sees a rocket traveling straight up at an angle of elevation of 24 degrees. If Sam is located 5 miles from the rocket Launch

julsineya [31]

Given :

Angle of elevation, Ф = 24°.

Distance of Sam from launchpad, D = 5 miles.

To Find :

How high is the rocket.

Solution :

Let, height is h.

We know, tan Ф is given by :

$tan \ \phi=\dfrac{h}{d}\\\\tan \ 24^{\circ}=\dfrac{h}{5}\\\\h = 5\times tan \ 24^{\circ}\\\\h = 2.226 \ miles$

Hence, this is the required solution.

The surface area of the three-dimensional figure is square centimeters?

Zina [86]

Answer:

Step-by-step explanation:

Alright, lets get started.

The surface area of the figure given is : The area of all shapes together

The figure has 2 similar triangles and 3 similar rectangles.

The area of 1 triangle =

$\frac{1}{2}*base*height$

The area of 1 triangle = $\frac{1}{2}*10*8.66=43.3$

So, the area of both triangles = $43.3*2=86.6$

The area of 1 rectangle = $width *length$

The of 1 rectangle = $10*15=150$

So, the area of all 3 rectangles = $3*150=450$

So, total area of figure = $86.6+450=536.6$

hence the surface area is 536.6 square centimeters : Answer

Hope it will help :)
