Answer:

The distance is 6.9115 miles.

Step-by-step explanation:

To solve this problem we can use a rule of three.

The length of a circumference is 2*pi*r, and if we have a fraction of the whole arc, we have that:

360 degrees -> arc of 2*pi*r

6 * (1/60) degrees -> arc of x

So we have that:

[tex]x * 360 = (1/10) * 2*\pi*r[/tex]

[tex]x = (1/10) * 2 * \pi * 3960 / 360[/tex]

[tex]x = (1/5) * \pi * 11[/tex]

[tex]x = (11/5)*\pi = 6.9115\ miles[/tex]

The distance is 6.9115 miles.

Answer:

35

Step-by-step explanation:

Given

the above lines of code

Required

What's the output

We'll analyze the code line by line

a = 2 + 6

At this point a = 8

b = 7 % 3

At this point b = 1. This is so because, the remainder of 7%3 is 1

c = a - b

At this point c = 7;

This is calculated by c = 8 - 1 = 7

c = c * 5

At this point; c = 35

This is calculated by: c = 7 * 5 = 35

print(c)

The value of c, which is 35 is printed

Answer:

No

Step-by-step explanation:

Does (3, 7) satisfy the first equation, y = -4x - 5?  Is 7 = -4(3) - 5 true?  NO.  Thus, (3, 7) cannot be a solution of the system

y=-4x-5

y=3x-2

The given point (3, 7) is not the solution in the given case.

A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.

Given equations are as follows,

y = -4x - 5                                (1)

y = 3x - 2                                 (2)

In order to find whether (3,7) is the solution for them, substitute x = 3 and y = 7 in both the equations and check the LHS and RHS of both.

For equation (1),

y = -4x - 5  

LHS is y  = 7

RHS = -4x - 5

       = -4 × 3 - 5

       = -17

Since, LHS ≠ RHS, the given values of x and y are not the solution for the given equation.

Now, equation(2) need not to be checked as the result for the given values is already not valid for equation(1).

Hence, the given coordinate  (3,7) is not the solution for the given equations.

Answer:

y = − 2/5x − 11

Step-by-step explanation:

To answer this, we need to put it into y = mx + b form. First, we need to find the slope. The equation for that is:

[tex]m = \frac{-9 - (-7)}{-5 - (-10)}[/tex]

[tex]m = -\frac{2}{5}[/tex]

We now have the slope. Now, we need to figure out b, or the y-intercept. Using y = mx + b, we substitute the slope and an x value (it doesn't matter whether it's -10 or -5, but let's use -10 for now) and a y value (same thing).

[tex]-7 = (-\frac{2}{5})(-10) + b[/tex]

[tex]b = -11[/tex]

All that's left to do is plug it in! Our final answer is:

[tex]y = - \frac{2}{5}x - 11[/tex]

Answer:

[tex]y = - \frac{2}{5} x - 11 [/tex]

Step-by-step explanation:

[tex] (-10,-7) and (-5,-9) \\ x_{1} = - 10 \\ y_{1} = - 7 \\ x_{2} = - 5 \\ y_{2} = - 9[/tex]

[tex] \frac{y - y_{1}}{x -x_{1} } = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } \\ \frac{y -( - 7) }{x - ( - 10)} = \frac{ - 9 - ( - 7)}{ - 5 - ( - 10)} \\ [/tex]

[tex]\frac{y + 7}{x + 10} = \frac{ - 2}{5} \\ cross \: multiply \\ 5(y + 7) = - 2(x + 10) \\ 5y + 35 = - 2x - 20[/tex]

[tex]collect \: like \: terms \: \\ 5y = - 2x - 20 - 35 \\ 5y = - 2x - 55 \\ \frac{ 5y = - 2x - 55}{ 5} \\[/tex]

Answer:

first complete the table by filling blank space on y axis

Then choosing a suitable scale, two squared box on the graph paper represent 1 unit for both axis.

Then draw a graph using x and y coordinate

(b) minimum value of y you dote a line from the turning point of the curve towards y axis then read the value

For this case it is -3.2

(c).To get the value of y when X=-3.5,

you dote alone from X =-3.5 on the X axis towards the curve vertically until you meet the curve then from the meeting point dote a line towards y axis and read the value.

which gives y=0.8

(d). draw a horizontal line at y=3 to meet the curve on both sides then dote a line from the meeting point vertically towards X axis and read the value on the X axis.

-3 , - 0.9 , 45

Hope this helps you

Explanation:

The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.

Answer:

See below.

Step-by-step explanation:

We have:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right)[/tex]

Simply plug in each value:

When x = 7.9, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx 0.0012[/tex]

When x = 7.99, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0001[/tex]

When x = 7.999, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0000[/tex]

When x = 8.001, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0000[/tex]

When x = 8.01, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0001[/tex]

And when x = 8.1, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0012[/tex]

From this pattern, we can conclude that:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right) = 0[/tex]

Since as the limit approaches 8, the value gets smaller and smaller and approaches zero.

Graphing this, we can confirm our answer.

Answer:

We have the relation:

(x + 3)^10

As the degree of the polynomial is 10, we know that we can have 10 roots.

The theorem says that this has at least one complex root.

As you know, this is actually trivial, because for example, 4 can be a complex number with an imaginary part equal to zero.

In this case, the polynomial is only zero if we have x = 3.

Then we have 10 roots that are equal to x = 3.

and those 10 roots can be real, or we can have 10 roots equal to 3 + 0*i, that is a complex number.

The perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Perimeter of a rectangle  = 2 (length and breadth)

the scale of the drawing is 1:500

let's assume that the length of the scale drawing playground is x and the breadth of the scale drawing playground is y. therefore, the length of the playground is 500x and the breadth is 500y.

Perimeter of the scale drawing playground = 2(length+breadth)

                                                                        [tex]= 2 (x+y)[/tex]

Perimeter of the real playground = 2(length+breadth)

                                                       [tex]=2 (500x+500y)\\=2 \times 500(x+y)\\= 1000 (x+y)[/tex]

Hence, the perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Answer:

9 cm

Step-by-step explanation:

Every centemeter represents three. 3km=1cm.

The number of kilometers/3= the number of centemeters.

the number of centemeters x 3= the number of kilometers.

We now have three equations to help us covert back and forth.

The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)

The number of kilometers/3= the number of centemeters.

27/3=the number of centemeters.

Thus, the answer is nine.

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = [tex]\frac{135}{45}=3[/tex]

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

[tex]a_n=a(r)^{n-1}[/tex]

[tex]a_n=45(3)^{n-1}[/tex]

Recursive formula of this sequence will be,

[tex]a_n=3(a_{n-1})[/tex], [tex]a_1=45[/tex]

Therefore, Option (B) will be the answer.

Explicação passo a passo:

Dado o seguinte:

Temperatura (T1) na decolagem localizada a 800 metros acima do nível do mar = 32 ° C

Temperatura (T2) à altitude máxima de 3200 metros acima do nível do mar = - 41 ° C

Portanto ;

A variação da temperatura externa entre o ponto de decolagem e a altitude máxima pode ser calculada por:

Diferença entre a temperatura de decolagem e a temperatura na altura máxima.

Variação externa da temperatura = (T1 - T2)

32 ° C - (-41 ° C)
