Answer:

13 + 12√2

Step-by-step explanation:

Not sure if there's an easier way, but here's my method:

Draw the radius lines from the center of the circle to each vertex of the octagon.  This will divide the octagon into 8 isosceles triangles, 4 big and 4 small.

Draw the height of one of the big triangles.  Define the angle between the height and the radius as A.  Similarly, draw the height of one of the small triangles.  Define the angle between the height and the radius as B.

Using trig, we can say:

sin A = 1.5 / r

sin B = 1 / r

The vertex angle of the large isosceles triangle is 2A, and the vertex angle of the small isosceles triangle is 2B.  Therefore:

4(2A) + 4(2B) = 360

A + B = 45

If we substitute into the first trig equation:

sin(45 − B) = 1.5 / r

sin 45 cos B − cos 45 sin B = 1.5 / r

1/√2 cos B − 1/√2 (1/r) = 1.5 / r

cos B − 1/r = 1.5√2 / r

cos B = (1 + 1.5√2) / r

If we substitute into the second trig equation:

sin(45 − A) = 1 / r

sin 45 cos A − cos 45 sin A = 1 / r

1/√2 cos A − 1/√2 (1.5/r) = 1 / r

cos A − 1.5/r = √2 / r

cos A = (1.5 + √2) / r

Using SAS area of a triangle, the area of the large triangle is:

Area = ½ r² sin(2A)

Area = ½ r² (2 sin A cos A)

Area = r² sin A cos A

Area = (r sin A) (r cos A)

Area = (1.5) (1.5 + √2)

Area = 2.25 + 1.5√2

Similarly, the area of a small triangle is:

Area = ½ r² sin(2B)

Area = ½ r² (2 sin B cos B)

Area = r² sin B cos B

Area = (r sin B) (r cos B)

Area = (1) (1 + 1.5√2)

Area = 1 + 1.5√2

So the total area is:

Area = 4(2.25 + 1.5√2) + 4(1 + 1.5√2)

Area = 9 + 6√2 + 4 + 6√2

Area = 13 + 12√2

Answer:

4.9 * 10^-6

Step-by-step explanation:

The number being multipled by 10 to the power of whatever is between 1 and 10, so in this case 4.9. Think of it as dividing by 10 a certain amount of times, which in this case it 6. So, it is 4.9*10^-6.

Answer:

no solution

Step-by-step explanation:

sqrt(3x+1) +7 = 5

Subtract 7 from each side

sqrt(3x+1) +7 -7= 5-7

sqrt(3x+1)  = -2

The sqrt cannot be negative so there is no solution

Answer:

C. both Vladimir and Robyn

Step-by-step explanation:

Just took the test. Hope this helps

Both Vladimir and Robyn are correct. Then the correct option is C.

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

[tex]\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)[/tex]

Vladimir says that the equation of the line that passes through points (-5, -3) and (10, 9) is y = (4/5) x + 1.

Robyn says that the line passes through the points (-10, -7) and (-15, -11).

Then the equation of the line will be

y + 7 = [(-11 + 7) / (-15 + 10)] (x + 10)

y + 7 = (4/5)x + 8

     y = (4/5)x + 1

Both Vladimir and Robyn are correct.

Then the correct option is C.

Answer:

x = 6.75

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtract.

First, combine like terms. Like terms by definition is terms that have the same amount of like variables.

7x -4x + 15 = 7x - 18 + 6

(7x - 4x) + 15 = 7x + (-18 + 6)

3x + 15 = 7x + (-12)

3x + 15 = 7x - 12

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7x and 15 from both sides:

3x (-7x) + 15 (-15) = 7x (-7x) - 12 (-15)

3x - 7x = -12 - 15

-4x = -27

Then, isolate the variable x. Divide - 4 from both sides:

(-4x)/-4 = (-27)/-4

x = -27/-4 = 27/4 = 6.75

x = 6.75 is your answer.

Step-by-step explanation:

Answer:

The equation of the line is;

y = -x + 2

Step-by-step explanation:

Here, we want to find the equation of a line which is perpendicular to the given line and passes through the given point.

Mathematically;

If two lines are perpendicular, then , the slope of the two lines when multiplied by each other equals -1

The given line is;

y = x + 1

let’s compare this with the standard form which is y = mx + c

In the standard form, the coefficient of x is the slope. In this case, the coefficient of x is 1 and thus this is our slope

So the slope of the second line will be;

since m1 * m2 = -1

and m1 = 1

m2 = -1/1 = -1

The slope of the second line is -1

Now to get the equation of the second line; we use the point slope form

That would be;

y-y1 = m(x-x1)

The point (x1,y1) = (1, 1) and m = -1

Thus;

y-1 = -1(x -1)

y-1 = -x + 1

y = -x + 1 + 1

y = -x + 2 or simply y = 2-x

Answer:

5x - 4 = 11

Step-by-step explanation:

4 less than 5 times a number equals 11

5 times a number minus 4 equals 11

(5*x) - 4 = 11

I hope this helps!!!

Answer:

second option

Step-by-step explanation:

five times a number: 5n (five times 2 = 5*2 = 10 like that)

four less than five times a number: 5n - 4

its like saying 7 less than 14. You take 7 away from 14 (14-7), not 7-14.

The whole thing equals to 11

Hence: 5n - 4 = 11 and n would equal 3
