Step-by-step explanation:

The answer to the problem is Undefined slope .

The answer is:

The radius of the circle is 29.21 units.

To solve the problem, we need to remember that the radius of a circle is the distance from its center to any point of the circle.

We can use the following equation to calculate the distance between the center and the given point:

[tex]distance=radius=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2} }[/tex]

So, we are given the information:

[tex]Center(12,5)\\Point(-6,-18)[/tex]

Where,

[tex]x_1=12\\y_1=5\\x_2=-6\\y_2=-18[/tex]

Now, substituting and calculating, we have:

[tex]radius=\sqrt{((-6)-(12))^{2}+((-18)-(5)^{2}}\\\\radius=\sqrt{(-18)^{2}+(-23)^{2}}=\sqrt{324+529}=\sqrt{853}=29.21units[/tex]

Hence, we have that the radius of the circle is 29.21 units.

Have a nice day!

Answer:

AB =  29.23

Step-by-step explanation:

Points to remember

Distance formula

Distance between two points (x₁, y₁) and (x₂, y₂) is given by

Distance = √[(x₂- x₁)² + (y₂ - y₁)²]

To find the radius

Center = (12, 5) and point on the circle = (-6, -18)

Radius = √[(x₂- x₁)² + (y₂ - y₁)²]

  =  √[(12 - - 6)² + (5 -  -18)²]

  = √[(12 + 6)² + (5 +18)²]

  =√[18² + 23²] = √[324 +529 ]  =  29.23

then you want to do 3.14 x 17×17 = .... then add them both and you got the area

1. a Early Pay: y = 45

 b. Deposit Plus: y = 12.00 + 4.00x

 c. Daily Pay: y = 6.00x

2.  Early pay = $25

   Deposit Plus = 12.00 + 4.00(4) =  12.00 + 16.00 = $28.00

 Daily Pay = 6.00(4) = $24.00

Daily Pay is the cheapest one.

3. Early Pay = $45

 Deposit Plus = 12.00 + 4.00(8) = 12.00 + 32.00 = $44.00

 Daily Pay = 6.00(8) = $48.00

Deposit Plus is the cheapest one.

4. Early Pay = $45

Deposit Plus = 12.00 + 4.00(12) = 12.00 + 48.00 = $60.00

Daily Pay = 6.00(12) = $72.00

Early Pay is the cheapest one.

5.  Since Jane likes to swim most days, it would be cheaper for her to do the Early pay option, because the price is a one time fee and she can swim every day.

Since Suzy doesn't really like to go swimming and might only go a couple times, it would be best for her to do the daily pay, that way she didn't spend any money up front if she doesn't swim at all.

Answer:

75 yd

Step-by-step explanation:

Given in the question a right angle triangle.

Base of right angle triangle = x

Height of right angle triangle = 40yd

To find x we will use trigonometry identity

here Ф = 62°

opposite = base

adjacent = height

Plug values in the formula to find x

Tan(62) = x / 40

   x        = (40)(Tan(62))

             = 75.229 yd

             ≈ 75 yd

The value of x is:

              x=75.2 yard.

We are given a right triangle with base 40 yard.

Also, the perpendicular length of the triangle corresponding to angle 62° is: x

Now we find the value of x using the trignometric formula as:

[tex]\tan 62\degree=\dfrac{x}{40}[/tex]

We know that the value of tan 62°=1.88073

Hence, we have:

[tex]1.88073=\dfrac{x}{40}\\\\\\x=40\times 1.88073\\\\\\x=75.2292[/tex]

         Hence, we have: x=75.2 yard

Answer:

(C) [tex]x=12[/tex]

Step-by-step explanation:

Given: It is given that OP is parallel to NQ and ON=7, NM=21. PQ=x, QM=36.

To find: The value of x.

Solution: It is given that OP is parallel to NQ and ON=7, NM=21. PQ=x, QM=36, thus using the proportionality theorem, we get

[tex]\frac{ON}{OM}=\frac{PQ}{PM}[/tex]

Substituting the given values, we have

[tex]\frac{7}{7+21}=\frac{x}{x+36}[/tex]

Upon solving the above equation, we get

[tex]\frac{7}{28}=\frac{x}{x+36}[/tex]

[tex]\frac{1}{4}=\frac{x}{x+36}[/tex]

[tex]x+36=4x[/tex]

[tex]x=12[/tex]

Hence, the value of x is 12 and option C is correct.

For this case we must find the difference of the following expressions:

[tex]0.00067\\2.3 * 10 ^ {- 5}[/tex]

For the second expression we must run the decimal 5 times to the left, because the exponent is negative, that is:

[tex]0.000023[/tex]

We subtract:

[tex]0.00067-0.000023 = 0.000647[/tex]

Answer:

(-2,4)

Step-by-step explanation:

y = x + 6

y = x^2 + 8x + 16

Since both equations are equal to y, we can set them equal to each other

x + 6  = x^2 + 8x + 16

Subtract x from each side

x -x + 6

= x^2 + 8x-x + 16

6 = x^2 +7x +16

Subtract 6 from each side

6-6 = x^2 +7x +16-6

0 = x^2 +7x +10

Factor

What 2 numbers multiply together to give us 10 and add together to give us 7?

5*2 = 10

5+2 =7

0 = (x+5) (x+2)

Using the zero product property

x+5 = 0  x+2 = 0

x = -5   x=-2

Now we need to find the y's that go with the x's

x=-5

y= x+6

y =-5+6

y=-1

(-5,1)

x=-2

y = -2+6

y=4

Answer:

The area of cylinder 949.536 in²

Step-by-step explanation:

Points to remember

Curved surface area of cylinder = 2πrh

Where r - radius of cylinder

h - Height of cylinder

To find the area of cylinder

Here r = diameter/2 = 6.3/2 = 3.15 in

h = 48 in

Area =  2πrh

 = 2 * 3.14 * 3.15 * 48

= 949.536 in²

Therefore area of cylinder 949.536 in²

Answer:

167.47 cubic feet

Step-by-step explanation:

Volume of the Cylinder

3.14×2^2×12=150.72

Volume of the Cone

3.14×2^2×4=50.24

50.24÷3=16.75

Total Volume

16.75+150.72=167.47

Volume is a three-dimensional scalar quantity. The total volume of the figure will be 167.552 ft³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the figure is the sum of the volume of the cone and the volume of the cylinder.

The volume of the cone = (1/3)πr²h = (1/3)×π×2²×4 = 5.334π ft³

The volume of the cylinder = πr²h = π × 2² × 12 = 48π ft³

The total volume of the figure can be written as,

Total Volume = Volume of cone + Volume of cylinder

                       = 5.33π ft³ + 48π ft³

                       = 167.552 ft³

Hence, the total volume of the figure will be 167.552 ft³.

Answer:

  a3=14, a4=19, a5=24

Step-by-step explanation:

Put the numbers where the symbols are and do the arithmetic.

  a3 = 2(a2) -(a1) = 2(9) -4 = 14

  a4 = 2(a3) -(a2) = 2(14) -9 = 19

  a5 = 2(a4) -(a3) = 2(19) -14 = 24

  a6 = 2(a5) -(a4) = 2(24) -19 = 29

_____

With a little work, you can show that this is an arithmetic sequence with a common difference of a2-a1 = 5.

Let d = a[2] -a[1]

Of course, the second term is that difference added to the first:

  a[2] = a[1] + (a[2] -a[1]) = a[1] +d

The third term is ...

  a[3] = 2a[2] -a[1] = a[2] +(a[2] -a[1]) = a[2] +d

  a[4] = 2a[3] -a[2] = a[3] +(a[3] -a[2]) = a[3] -(a[2] +d) -a[2] = a[3] +d

Answer:

see the attachment for a graph

Step-by-step explanation:

When asked to graph an equation like this, you can first recognize that the equation you are given is in "slope-intercept" form:

y = mx + b . . . . . m is the slope; b is the y-intercept.

This immediately tells you one point on the graph: the y-intercept at (0, -4).

Another point on the graph can be found by making use of the slope to choose a point that is different from the y-intercept by the rise and run indicated by the slope.

Here, the slope is rise/run = -5/6, which means the line "rises" -5 units for each "run" of 6 units. Alternatively, it rises 5 units for a run of -6 units. That is the second point we have plotted on the graph below. Subtracting 6 from x=0 gives x=-6; adding 5 to y=-4 gives y=1, so our second point is (-6, 1).

Tan (b) = 2/11

 b = tan^-1(2/11)

b =  10.30
