You would place a #line going from negatives on left to positive on right then place a point at positive 5 and go back 5, 3 times

Find the measure of a central angle of a regular polygon with 10 sides

Paraphin [41]

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is $(n-2)180$ , where n = total number of sides.

Thus, we substitute n for 10, and you get:

$(10-2)180=1440$

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.

Jessica and Mike are making presentations for a class project. Jessica's slideshow starts with a verbal introduction that is 16

uysha [10]

Answer:

they both has 7 slides and the presentation had a duration of 28 seconds

Step-by-step explanation:

we have to setup equation that makes them equal to each other if you know what i mean. 2x+16=3x+10

then we just solve for x

2x+16=3x+10

subtract 10 from each side

2x+6=3x

step 2 subtract 2x from each side

x=6

so both of their presentations are 7 slides long

then to find the length of their presentations we just plug in 6 to one of the equations

2(6)+16

2x6=12 12+16=28 so both of their presentations were 28 seconds

Write an equation for the nth term of the geometric sequence. Then find the 7th term. 2,-6,18,-54,...

Sonja [21]

soln,

from the series,

a = 2

t2 = -6

r = t2/a

$= \frac{ - 6}{2}$

= -3

therefore, tn =

${ar}^{n - 1}$

$= {2 \times - 3}^{n - 1}$

now,

seventh term =

${2 \times - 3}^{7 - 1}$

$= {2 \times - 3}^{6}$

$= 2 \times 729$

$= 1458$
