3. The measure of an interior angle of a regular polygon is 140. Find the number of sides the polygon has.​

Answers

Answer 1

Answer:

I hope this will help u

Step-by-step explanation:

Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

In ANOP, the measure of ZP=90°, the measure of ZN=26°, and OP = 13 feet. Find
the length of PN to the nearest tenth of a foot.



Answers

Answer:

Length of PN = 26.65 ft (Approx.)

Step-by-step explanation:

Given:

In ΔNOP

∠ P = 90°

∠ N = 26°

OP = 13 ft

Find:

Length of PN

Computation:

using trigonometry application

Tan 26 = 13 / PN

0.4877 = 13 / PN

Length of PN = 26.65 ft (Approx.)

What is the y intercept of a line that passes through the points (2, -2.5) and (4, -2)

Answers

Answer:

-3

Step-by-step explanation:

To find the slope of this line, you have to subtract that first y coordinate from the second y coordinate, and divide that by the quantity equal to the second x coordinate minus the first.

-2 - -2.5 = 0.5

4 - 2 = 2

0.5/2 = 1/4

Now you plug in the info you already have into a y=mx+b format. Chose one of the pairs of coordinates given in instruction to be the x and y values.

-2 = 1/4(4) + b

-2 = 1 + b

-3 = b

-3 is the y-intercept.

al comprar una estufa de 5579 le cobran 9%de su costo extra para llevarlo a domicilio cuanto se pagará en total si la estufa será llevada​

Answers

Answer:

6081.11

Step-by-step explanation:

Para resolverlo debes usar la regla de 3 simples:

La estufa cuesta $5,579 y te cobrarán el 9% para llevarlo a domicilio para eso realizarás esta operación

5579  =   100%

  X    =       9%

Ahora debes multiplicar 5579 x 9 = 50211

Ahora debes dividirlo entre 100  50211 ÷ 100 = 502.11 entonces el 9% es $502.11

Para terminar debes sumar el precio de la estufa y lo que cuesta llevarlo a domicilio     5579 + 502.11 = 6081.11

En total pagará $6081.11

The graph of f(x) = x2 was transformed tu
create the graph of d(x) = f(x) + 9. Which of
the following attributes will be the same for the
graphs f(x) and d(x)?
1. the domain
11. the range
III. the axis of symmetry

Answers

Answer:

i: the domain.

iii: the axis of symmetry.

Step-by-step explanation:

We have the function:

f(x) = x^2

The domain of this function is the set of all real numbers, and the range is:

R: [0, ∞)

(because 0 is the minimum of x^2)

Now we have the transformation:

d(x) = f(x) + 9 = x^2 + 9

Notice that this is only a vertical translation of 9 units, then there is no horizontal movement, then the axis of symmetry does not change.

Also, in d(x) there is no value of x that makes a problem, so the domain is the set of all real numbers, then the domain does not change.

And d(x) = x^2 + 9 has the minimum at x = 0, then the minimum is:

d(0) = 0^2 + 9 = 9

Then the range is:

R: [9,  ∞)

Then the range changes.

So we can conclude that the attributes that will be the same for f(x) and d(x) are:

i: the domain.

iii: the axis of symmetry.

Step-by-step explanation:

At a scrapbooking party, guests brought a certain number of photographs to use, based on
how many pages they will be assembling. Ellie plans to assemble 4 small pages and 7 large
pages and brought a total of 22 photographs to use. Bridgette brought 30 photographs,
which is enough to assemble 8 small pages and 7 large pages. Assuming that the number of
photographs on a page remains constant, how many photographs fit on a small page and a
large page?
A small page can fit
photographs, and a large one can fit
photographs.

Answers

Answer:

A small page can fit 2 photographs, and a large on can fit 2 photographs.

Step-by-step explanation:

Let the number of photographs on the small page be represented by m and that of large one by n.

Since the number of photographs on a page remains constant, then;

4m + 7n = 22 ........... 1

8m + 7n = 30 .......... 2

Multiply equation 1 by 2, and 2 by 1 to have;

8m + 14n = 44 ....... 3

8m + 7n = 30 ......... 4

subtract equation 4 from 3,

7n = 14

n = 2

Substitute the value of n in equation 1

4m + 7(2) = 22

4m + 14 = 22

4m = 8

m = 2

m = 2, n = 2

Therefore, a small page can fit 2 photographs, and a large on can fit 2 photographs so that the number of photographs n a page is constant.

What is the value of x in the following triangle?

Answers

Answer:

x=-10/3

Step-by-step explanation:

Answer: x = 17

Step-by-step explanation:

Triangle angle sum theorem states the three interior angles of a triangle sum to 180 degrees. Add all of the angles together and set equal to 180 to solve for x.

(3x)+(6x+10)+x= 180. Combine like terms.

10x + 10= 180. Subtract 10 from both sides.

10x = 170. Divide both sides by 10.

X = 17

If the slope between the points (-5,7) and (4,x) is 1, then
what is the value of x?

Answers

9514 1404 393

Answer:

  16

Step-by-step explanation:

The equation of a line with slope m=1 through the point (h, k) = (-5, 7) will be ...

  y -k = m(x -h)

  y -7 = x +5

  y = x +12

Then for x = 4, the value of y is ...

  y = 4 +12 = 16

The point is (4, x) = (4, 16), so x = 16.

Answer:

16

Step-by-step explanation:

Given that the slope of the line is 1 . And it passes through the points (-5,7) and (4,x) .We know that slope is difference of ordinate by difference of abssica . So that ,

[tex]\implies Slope =\dfrac{y_2-y_1}{x_2-x_1}\\\\\implies 1 =\dfrac{ 7-x}{-5-4} \\\\\implies 1 \times -9 = 7-x \\\\\implies -9 -7 = -x \\\\\implies \underline{\underline{ x = 16 }}[/tex]

Hence the required answer is 16 .

What is the solution of log2x + 6 8 = 3?

Answers

Answer:

x=-3

Step-by-step explanation:

log(2x + 6) +8 = 3

Solve this log equation for x

First subtract 8 from both sides

log(2x+6)= -5

Now we convert it into exponential form

If log(x) = a then 10^a = x

log(2x+6)= -5 becomes

subtract 6 from both sides

Now we divide by 2 on both sides

x= -3 approximately
