Write 2.71 as a simplified fraction.

Step-by-step explanation:

Area of a circle is pi times r-square

[tex]\pi \: {r}^{2} [/tex]

So...

[tex] \frac{22}{7} \times \frac{21}{2} \times \frac{21}{2} = \frac{22 \times {21}^{2} }{28} [/tex]

Do the rest yourself, my calculator and pen are not handy. Sorry

the answer for this question is 5.51

========================================================

Explanation:

Point C is located at (-6,3). The x coordinate is x = -6.

Going from x = -6 to x = -1 is 5 units to the right. We move another 5 units to the right to go from x = -1 to x = 4 when arriving at its reflected location (4,3). The y coordinate stays the same the entire time.

It might help to refer to the diagram below.

Answer:

It is Tn = 9n - 11

Step-by-step explanation:

It is an arithmetic progression:

[tex]T_{n} = a + (n - 1)d[/tex]

a is the first term, a = -2

n is number of terms

d is common difference, d = 7-(-2) = 9

[tex]T_{n} = - 2 + \{ (n - 1) \times 9 \} \\ T_{n} = - 2 + 9n - 9 \\ T_{n} = - 11 + 9n \\ T_{n} = 9n - 11[/tex]

Answer:

[tex]T_{n}[/tex] = 9n - 11

Step-by-step explanation:

There is a common difference between consecutive terms, that is

7 - (- 2) = 16 - 7 = 9

This indicates the sequence is arithmetic with nth term

[tex]T_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 2 and d = 9 , then

[tex]T_{n}[/tex] = - 2 + 9(n - 1) = - 2 + 9n - 9 = 9n - 11

Answer:

Step-by-step explanation:

None of the above.

It is a complex number.  The sqrt(-9) is defined as 3i.

i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.

Answer:

theta = 4.5642792103077898247

Step-by-step explanation:

0 <= theta < 2Pi sin(theta) = 1/2

so

2Pi sin(theta) = 1/2

Pi sin(theta) = 1/4

sin(theta) = 1/(4Pi)

sin(theta)  = .0795774715459

theta = arcsin(.0795774715459) = 4.5642792103077898247

Answer and Step-by-step explanation:

1-6

a.

What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.

The order that works is second machine, then first machine.

Second Machine:

y = [tex](6)^{2} -6[/tex] = 36 - 6 = 30

Plug into first machine now.

First Machine:

y = [tex]\sqrt{(30) - 5} = \sqrt{25} = 5[/tex]

We see that the result is 5.

b. If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.

However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.

1-7. The absolute value of a value is the positive version of that value.

a. |54| = 54

b. [tex]-|-7\frac{3}{5}|[/tex] = [tex]-7\frac{3}{5}[/tex]

c. |3| - |-1| = 3 - 1 = 2

d. |2.2 - 5.13| = |-2.93| = 2.93

b. The amount of squares on each side of the figure increases by 1.

c. There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.

1-9.

a. -42 - 17 = -59

b. 8 - (-9) = 8 + 9 = 17

c. 8(-9) = -72

d. -42 ÷ (-7) = 6

e. -2(-3)(-4) = 6(-4) = 24

f. -18 - 7 = -25

g. [tex](-5)^{2}[/tex] = 25

h. [tex]-5^{2} = -(5)^2 = -(25)[/tex] = -25

i. [tex]\sqrt{49}[/tex] = 7

1-10.  x = 2 Plug 2 in for x, then solve.

a. y = 7 - 3(2) = 7 - 6 = 1

b. y = [tex](2)^2 -1[/tex] = 4 - 1 = 3

c. y = [tex]\frac{18}{2}[/tex] = 9

Answer:

Step-by-step explanation

In these type of questions we can use a trick to find answer

let's say we have two linear equation

1) ax+by+c=0

2)mx+ny+t=0

if  a/m = b/e ≠ c/f  that means we don't have any solution for these two equations ( that's because of analitic geometry)

so,

2x-ky-14=0

5x-2y-5=0

If k is 4/5, the system of equations will have no solution because the lines are parallel.

Two or more expressions with an Equal sign is called as Equation.

The system will have no solution if the two equations represent parallel lines, because parallel lines do not intersect.

To determine if the lines are parallel, we can compare the slopes of the two lines.

The slope of the first line is 2, since it is the coefficient of x when we solve for y:

2x - ky = 14

ky = 2x - 14

y = (2/k)x - 14/k

The slope of the second line is 5/2, since it is the coefficient of x when we solve for y:

5x - 2y = 5

2y = 5x - 5

y = (5/2)x - 5/2

Therefore, the two lines are parallel if the slopes are equal:

2/k = 5/2

4 = 5k

k = 4/5

So, if k = 4/5, the system of equations will have no solution because the lines are parallel.

Answer:

x = 18°

Step-by-step explanation:

∠AOB and ∠BOD form linear pair of angles, so they are supplementary, i.e., their sum is 180°.

130° + (2x + 14)° = 180°

=> 130° + 2x° + 14° = 180°

=> 2x° = 180° - 130° - 14°

=> 2x° = 36°

=> x = 36°/2°

=> x = 18°
