Use the distance formula to find the perimeter of the triangle below. Round you answer to the nearest hundredth.

Murrr4er [49]

<u>jAlright, let's take this problem step-by-step</u>:

<u>What is the perimeter</u>:

⇒ all the side-lengths added up

⇒ <em>need</em> to find side-length using distance formula

$Distance_._. Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

- (x₁,y₁): first point

- (x₂,y₂): second point

<u>Let's solve</u>:

Find length of <em>AC</em>

⇒ <em>first point</em>: (5,7)

<em> ⇒ second point: </em>(3,3)

<em> </em> $Distance =\sqrt{(3-5)^2+(3-7)^2} =\sqrt{4+16} =\sqrt{20} =4.472$

Find length of AB

⇒ <em>first point:</em> (5,7)

<em> ⇒ second point:</em>(8,6)

<em> </em> $Distance=\sqrt{(8-5)^2+(6-7)^2} =\sqrt{9+1} =\sqrt{10}=3.162$

Find length of BC

⇒<em> first point: </em>(8,6)

<em> ⇒ second point: </em>(3,3)

<em> </em> $Distance = \sqrt{(3-8)^2+(3-6)^2} =\sqrt{25+9} =\sqrt{34}=5.831$

<u>Now let's solve for the perimeter</u>:

$Perimeter = 4.472+ 3.126+ 5.831=13.429$

<u>Answer: 13.43</u> (<em>rounded to the nearest hundredth)</em>

Hope that helps!

Luden [163]

Answer:

Step-by-step explanation:

time=1 years

interest=principal*time*rate/100

=8000*1*8/100

=64000/100

=640

therefore interest=640

If a Rubik’s Cube has a volume of 384 cubic centimeters, how long is one side of the cube?

Tatiana [17]

The answer is: "7.268 cm" .
________________________
Explanation:
________________________
Since the formula for the volume, "V", of a cube, is:

V = s³ ;

in which: "s" = side length of a cube;

Given: "V = 384 cm³ " ; Plug this value into the formula; to solve for "s" ;

V = s³ ;

↔ s³ = V ;

s³ = V ;

s³ = 384 cm³ ;

Take the "cubic root" of EACH SIDE of the equation; to isolate "s" on one side of the equation ; & to solve for "s" ;
_________________________________________________
∛(s³) = ∛ (384 cm³) ;

s = 7.2684823713285586 cm

Round to: 7.268 cm .
