What is the area of a pentagon using the side length of 4

Mathematics
1 answer:
ehidna [41]3 years ago
3 0
In this equation, n = # of sides
Area = n * (side length)² / 4*tan (180 / n)
Area = 5 * 4² / 4 * tan (36)
Area = 80 / 4 * 0.72654
<span><span><span>Area = 80 / 2.90616 </span> </span> </span>
Area =  <span> <span> <span> 27.5277341922 </span> </span> </span>

Find the distance between the following points: (0,0,0) and (-2,6,3)
marusya05 [52]

9514 1404 393

Answer:

  3.  7

Step-by-step explanation:

The distance formula applies in 3 dimensions as well as 2.

  d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

  d = √((-2)² +6² +3²) = √(4 +36 +9) = √49

  d = 7

The distance between the two points is 7 units.

Which lines are parellele
natali 33 [55]

Line 1 and Line 4 are parallel lines

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept of the line.

<u>To find the slope of each line:</u>

Line 1: y=-\frac{3}{4} x-6

Slope (m_1)=-\frac{3}{4}

Line 2: y-7=-4(x+9)

y-7=-4x-36

Add 7 on both sides, we get

y=-4x-29

Slope (m_2)=-4

Line 3: y=-2 x+6

Slope (m_3)=-2

Line 4: x+\frac{4}{3} y=-5

Subtract x from both sides, we get

\frac{4}{3} y=-x-5

Multiply  by \frac{3}{4} on both sides, we get

y=-\frac{3}{4}x-\frac{15}{4}

Slope (m_4)=-\frac{3}{4}

<em>Two lines are parallel, if their slopes are equal.</em>

From the above slopes,

m_1=m_4

Therefore Line 1 and Line 4 are parallel lines.

What are the next three terms of each sequence?5,7.5
leva [86]

Answer:

The next three terms are 10, 12.5 and 15

Step-by-step explanation:

I. As you can see 5 and 7.5 is came from 5, 5 + 2.5

So given y = 5 + 2.5( x - 1 ) when y is output, x is term

II. Perform x = 3, 4, 5

        So y = 5 + 2.5( 3 - 1 )

                = 5 + 5

          3rd = 10

             y = 5 + 2.5( 4 - 1 )

                = 5 + 7.5

            4th = 12.5

             y = 5 + 2.5 (5 - 1)

                = 5 + 10

             5th = 15
