Answer:(x-0)^2 + (y-0)^2=30^2

Step-by-step explanation:

The equation of the circle is x^2 +y^2 = 7656.25

The given parameters are:

Center = (0,0)

Diameter = 175

The equation of a circle is represented as:

(x - a)^2 +(y - b)^2 = r^2

Where

Center = (a,b) = (0,0)

r = radius = 175/2

So, we have:

(x - 0)^2 +(y - 0)^2 = (175/2)^2

Evaluate

x^2 +y^2 = 7656.25

Hence, the equation of the circle is x^2 +y^2 = 7656.25

Answer:

y - 7 = -8(x-2)

Step-by-step explanation:

The point slope form is: y-y1=m(x-x1)

From the information that was given, we know our two points: (2,7)

From here, we can fill in some of the missing information: y-y1=m(x-x1) → y - 7 = m(x-2)

Now I can't tell if you wrote down -8 or just 8, but just in case my answer isn't the right number.

The answer would either be: y - 7 = -8(x-2)    [if you wrote down -8 as the slope]

OR

The answer would be: y - 7 = 8(x-2)    [if you wrote down 8 as the slope]

Answer:

$ 94.28

Step-by-step explanation:

75 x 1.18 = 88.50

75 x .077 = 5.78

88.50+5.78= 94.28

Answer:

B) 256

Step-by-step explanation:

You are doubling the amount of boxes there are each time:

Pattern 1: 1 box

Pattern 2: 2 boxes

Pattern 3: 4 boxes

Pattern 4: 8 boxes

Pattern 5: 16 boxes

Pattern 6: 32 boxes

Pattern 7: 64 boxes.

Each box takes 4 matches to create. There are 64 boxes in total by the 7th pattern. Multiply 4 with 64:

64 x 4 = 256

B) 256 matches is your answer.

Do you want me to explain it?

Answer:

h = 12 m

[tex] v_{cylinder}= 235.5 \: {m}^{3} [/tex]

Step-by-step explanation:

Radius of cylinder (r) = 5/2 = 2.5 m

[tex] {h}^{2} = {13}^{2} - {5}^{2} \\ h = \sqrt{ {13}^{2} - {5}^{2} } \\ h = \sqrt{169 - 25} \\ h = \sqrt{144} \\ h = 12 \\ \\ v_{cylinder} = \pi {r}^{2} h \\ v_{cylinder}= 3.14(2.5) ^{2} (12) \\ v_{cylinder}= 235.5 \: {m}^{3} [/tex]

Answer:

centre of the circle(h,k)=(5,2)

radius(r)=10

Step-by-step explanation:

Now,

equation of the circle is giveb by (x-h)^2+(y-k)^2=r^2

or,(x-5)^2+(y-2)^2=(10)^2

or,x^2-10x+25+y^2-4y+4=100

or,x^2+y^2-10x-4y+29-100=0

or,x^2+y^2-10x-4y-71=0

Answer:

[tex]D.\ (3,\frac{1}{8})[/tex]

Step-by-step explanation:

Given

[tex]y = (\frac{1}{2})^x[/tex]

Required

Points that lies on the above graph

From the given options, only option D lies on the point and the proof is as follows:

[tex]D.\ (3,\frac{1}{8})[/tex]

This means that:

[tex]x = 3;\ y = \frac{1}{8}[/tex]

Substitute [tex]x = 3;\ y = \frac{1}{8}[/tex] in [tex]y = (\frac{1}{2})^x[/tex]

[tex]\frac{1}{8} = (\frac{1}{2})^3[/tex]

[tex]\frac{1}{8} = \frac{1^3}{2^3}[/tex]

[tex]\frac{1}{8} = \frac{1}{8}[/tex]

See that the values at the right and left hand side of the equation are the same.

This means that, [tex]D.\ (3,\frac{1}{8})[/tex] lies on [tex]y = (\frac{1}{2})^x[/tex]

Answer:

r=8

Step-by-step explanation:

The number we are looking for is represented by 'r' which is multiplied by 8

Answer:

it would be 200 points. Lets assume that all of the apprentice magicians are 143 years old. If so, then 143 x 7 = 1001. 1001 + 200 = 1201. 1021 ÷ 8 (the number of magicians) the answer is 150. so the age of head wizard is actually 200 years.

A is your answer just multiply it by 14 then add it by 5 it looks as if all sides are equal.
