So for this, we first have to find the exterior angle. We can do this by subtracting 135 from 180 (linear pair theorem). The difference is 45°.

Next, since all exterior angles add up to 360°, divide 360 by 45 and your answer will be 8 sides, or A.

here we have given the interior angles as 135 degrees.

we have give that it is a polygon

we need to find how many sides does it have.

we need to find exterior angle.

we know that sum of interior and exterior angle is 180.

x be the exterior angle.

x+135=180,x=45

we have formula to find the number of sides n=360/exterior angle

n=360/45=8

the regular polygon will have 8 sides .

Solve for y in terms of x
Alika [10]

Answer:

(a) 3 - 2x - 2x²  (b) -21

Step-by-step explanation:

given, y +2x² = 3 -2x

make y the subject:

y = 3 - 2x - 2x²

if y = f(x)

then

f(x) = 3 - 2x - 2x²

(b)<u> to find f(3) we need to replace x with 3:</u>

What dose this equal 2(6x-4)=3(6x+2)
AveGali [126]

Answer:

-7/3

Step-by-step explanation:

2(6−4)=3(6+2)

2(6x-4)=3(6x+2)

Solve

1

Distribute

2(6−4)=3(6+2)

{\color{#c92786}{2(6x-4)}}=3(6x+2)

12−8=3(6+2)

{\color{#c92786}{12x-8}}=3(6x+2)

2

Distribute

12−8=3(6+2)

12x-8={\color{#c92786}{3(6x+2)}}

12−8=18+6

12x-8={\color{#c92786}{18x+6}}

3

Add

8

8

to both sides of the equation

12−8=18+6

12x-8=18x+6

12−8+8=18+6+8

12x-8+{\color{#c92786}{8}}=18x+6+{\color{#c92786}{8}}

A ball is released at a height of 8 inches to roll inside a half-cylinder it rolls to a height of 2 inches on the other side of
yuradex [85]

Answer:

C) 1/8 inch

Step-by-step explanation:

We are given the explicit formula

a_n=2(\frac{1}{4})^{n-1}, where n is the term number.

The third climb up would be the third term; this means we replace n with 3:

a_3=2(\frac{1}{4})^{3-1}\\\\a_3=2(\frac{1}{4})^2=2(\frac{1}{4}\times \frac{1}{4})=2(\frac{1}{16})=\frac{2}{16}=\frac{1}{8}
