Answer:

Area : 27.5

Perimeter : 20

Step-by-step explanation:

All sides of a regular pentagon have the same length

1 side = 4

4x5 = 20 = Perimeter

Pentagon area formula :

1/4(sqrt(5(5+2sqrt(5)))x)

Plug x in (side length)

27.53

brooooo ahí te pregunta tiempo no distancia así que son exactamente 13 minutos con 47 segundos. un gusto en ayudar

The total time elapsed will be 1073 seconds.

An expression in mathematics is a combination of terms both constants and variables.

Given is that the red line cable car is 32 km long and advances at a speed of 6 m/s. You go up to the top and -

Time elapsed in first advancement = 50 seconds.

Total time after second backward motion = 50 + 3 = 53 seconds.

Total time after third forward motion = 53 + 300 = 353 seconds

Total time after fourth backward motion = 353 + 120 = 473 seconds

Total time after fifth forward motion = 473 seconds + 600 = 1073 seconds.

Therefore, the total time elapsed will be 1073 seconds.

{Question in english -

The red line cable car is 32 km long and advances at a speed of 6 m/s. Suppose you go up to the top and advance for 50 seconds and the cable car stops and begins to go backwards for 3 seconds, then it advances again for 5 minutes. and again it goes backwards for 2 minutes to then advance again to its final stop in the next 10 minutes, how much time will have elapsed?}

Answer:

The zeroes of [tex]g(x)=4x^4+4x^3-11x^2-12x-3[/tex] are [tex]-\sqrt{3}, -\frac{1}{2}, \sqrt{3}[/tex], or approximately [tex]-1.732, -0.500, 1.732[/tex].

Step-by-step explanation:

By inputting the function in a graphical calculator we can see that the roots of the graph of [tex]g[/tex] are about [tex]x=-1.732, x = 0.500, x = 1.732[/tex] (make sure you click on the points of interests).

Notice that [tex]g(x) = 4x^4+4x^3-11x^2-12x-3 = (2x-1)^2(x^2-3).[/tex] So the roots can be calculated with [tex](2x-1)^2 = 0 \vee x^2 - 3 = 0[/tex], yielding [tex]x = -\frac{1}{2} \vee x = \pm\sqrt{3}[/tex].

Answer:

(x-9)°+6x=180°[by linear pair]

7x-9=180°

7x=180°+9

7x=189°

x=189/7

x=27

(x-9)°=27-9=18°

(6x)°=6×27=162°

The angle measures are 18 degrees and 162 degrees.

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

In the given figure ∠1=x-9 and ∠2=6x

The sum of ∠1 and ∠2 is 180 degrees by linear pair.

∠1 +∠2 =180

x-9+6x=180

Add the x variable terms

5x-9=180

Add 9 on both sides

5x=189

Divide both sides by 5

x=27

Now substitute value of x in angle 1 and angle 2.

∠1=x-9=27-9=18 degrees

∠2=6x=6(27)=162 degrees.

Hence, the angle measures are 18 degrees and 162 degrees.

Step-by-step explanation:

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

The range of the given table would be set of all possible y-values as {-6, -2, 5}​ which is the correct answer would be an option (D).

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

We have been given that table as:

x     y

-3    -6

1     -2

7     5

As per the given table, the required solution would be as:

The range of a function is the set of all possible output values of the function. In this case, the output values of the function are the y-values in the table. The range of the function table is the set of all possible y-values, which in this case is {-6, -2, 5}.

Therefore, the range of the function table is therefore -6 to 5.

The image point of (-7, 1) after reflection across the y-axis is:

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:

Answer:

∠F = 32°

Step-by-step explanation:

ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent

∠D = ∠A = 108

∠B = ∠E = 40

∠C = ∠F

In ΔDEF,

∠D +∠E + ∠F = 180        {Angle sum property of triangle}

108 + 40 + ∠F = 180

        148 +∠F = 180

                ∠F = 180 - 148

               ∠F = 32°

Answer:

Lowest root is 0 degrees.

Step-by-step explanation:

divide through by 9:

sec x + tan x = 1

sec^2x = 1 + tan^2 x so

√(1 + tan^2x) + tanx = 1

√(1 + tan^2x)  = 1 - tanx

Squaring both sides:

1 + tan^2 x = 1 - 2 tanx + tan^2 x

1 = 1 - 2 tan x

2tanx = 0

x = 0 degree.
