The measure of each interior angle of a regular polygon is 120°. Find the number of sides.

Answer:

6

Step-by-step explanation:

You can memorize these for the smaller shapes

for equilateral polygons:

triangle: 60

square: 90

pentagon: 108

hexagon: 120

Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.

So the measure of each angle on average would be (s-2)*180/s.

There (s-2)*180/s = 120

180(s-2) = 120s

180s-360 = 120s

60s = 360

s = 6

Troyanec [42]

Answer: 40%

Step-by-step explanation:

Chocolate chip and oatmeal cookies: 9+35 = 44

Total cookies = 9+21+15+35+30 = 110

What percent is 44 of 110 (%/100 = is/of)

x/100 = 44/110 (cross multiplication)

4400/110 = 40

If dy/dx=2xy and y(0)=1.<br> What is y(1) equal to?
Llana [10]

dy/dx = 2xy 
dy/y = (2x)dx 
INT(1/y)dy = INT(2x)dx 
ln y + c = x^2 + d 
ln y = x^2 + constant 
y = e^(x^2 + constant) 

1 = e^constant ... so constant=0 ... so y = e^(x^2) 

Verification: 

y = e^(x^2) 
dy/dx = 2x*e^(x^2) = 2xy 
<span>and e^(0^2) = e^0 = 1


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!</span>

Answer: x=1, y=4.162

X=2, y=5.022; x=3, y=5.882; x=4, y=6.742; x=5, y=7.602...

Step-by-step explanation:

We pick values for x, starting from 1.

When x=1,

Y = 0.860×1 + 3.302 = 4.162

When x=2,

Y = 0.860×2 + 3.302 = 5.022

When x=3,

Y = 0.860×3 + 3.302 = 5.882

When x=4,

Y = 0.860×4 + 3.302 = 6.742

When x=5,

Y = 0.860×5 + 3.302 = 7.602

...
