Find an equation of the largest sphere with center (10, 8 , 7) that is contained completely in the first octant.

Answers

Answer:

The equation of the largest sphere with center (10, 8, 7) that is contained completely in the first octant is [tex](x-10)^{2} + (y - 8)^{2} + (z - 7)^{2} = 49[/tex].

Step-by-step explanation:

A sphere is described by its radius and center, the radius of the largest sphere contained in the first octant are determined by the least distance of the center with respect to an orthogonal axis, that is:

Distance regarding x-axis:

[tex]d_{x} = 10 - 0[/tex]

[tex]d_{x} = 10[/tex]

Distance regarding y-axis:

[tex]d_{y} = 8 - 0[/tex]

[tex]d_{y} = 8[/tex]

Distance regarding z-axis:

[tex]d_{z} = 7 - 0[/tex]

[tex]d_{z} = 7[/tex]

Hence, the radius of the sphere must have a measure of 7. The equation of the sphere is represented by the following geometric locus:

[tex](x-h)^{2} + (y-k)^{2} + (z - j)^{2} = r^{2}[/tex] (1)

Where:

[tex]h, k, j[/tex] - Coordinates of the center.

[tex]r[/tex] - Radius of the sphere.

If we know that [tex](h,k,j) = (10, 8, 7)[/tex] and [tex]r = 7[/tex], then the equation of the largest sphere with center (10, 8, 7) that is contained completely in the first octant is:

[tex](x-10)^{2} + (y - 8)^{2} + (z - 7)^{2} = 49[/tex]

Answers

Answer:

[tex]\text{a) }1,080^{\circ}, \\\text{b) }360^{\circ}, \\\text{c) }135^{\circ}, \\\text{d) }45^{\circ}[/tex]

Step-by-step explanation:

a) The sum of the interior angles of a polygon with [tex]n[/tex] sides is equal to [tex](n-2)180[/tex]. Since an octagon has 8 sides, substitute in [tex]n=8[/tex]:

[tex](6-2)180=\boxed{1,080^{\circ}}[/tex]

b) The sum of the exterior angles for any polygon is equal to [tex]360^{\circ}[/tex].

c) By definition, all regular shapes have equal angles and sides. Since we've found the total sum of the interior angles of an octagon in part a, each interior angle of a regular octagon must be [tex]\frac{1080}{8}=\boxed{135^{\circ}}[/tex]

d) Similar to part c, all regular shapes must have equal angles and sides. From part b, we know the sum of the exterior angles of a octagon is [tex]360^{\circ}[/tex], thus we have [tex]\frac{360}{8}=\boxed{45^{\circ}}[/tex]

Step-by-step explanation:

Let x be the earnings

2x+10 = 253

Subtract 10 from each side

2x = 243

Divide by 2

Answers

Answer:

1/9

Step-by-step explanation:

First find the area of each circle with the formula a= Pi(r^2)

Area of circle with a radius of 4

a= Pi(4^2)

a= 16pi

Area of circle with radius of 12

a= Pi(12^2)

a= 144pi

Now use these values to represent the areas of the circles as a ratio

16pi/ 144pi

The pi's cancel out in this ratio

So we are left with

16/144

We can then go ahead and simplify these numbers as well to get the ratio in the simplest form

Answer:

[tex]s = - \frac{1}{4} [/tex]

Step-by-step explanation:

For m to be equal to n,

[tex]2s = \frac{2s- 1}{3} [/tex]

Multiply both sides by 3:

[tex]6s = 2s - 1[/tex]

Minus 2s on both sides:

6.b.Find the equation of the circle lies on 2x-3y+1=0 and the circle passing through the points (-1,2) and (2,3).​

Answers

Answer:

(x + 1)² + (y - 7)² = 25

Step-by-step explanation:

Perpendicular bisector of the chord connecting the the points (-1,2) and (2,3) is also passing through the center of the circle.

We'll find the equation of the line and solve the system to find the center.

Midpoint of the chord:

((-1 + 2)/2, (2 + 3)/2) = (0.5, 2.5)

Equation of the line through chord (-1,2) and (2,3):

m = (3 - 2)/(2 + 1) = 1/3y - 2 = 1/3(x + 1)y = 1/3x + 7/3

Perpendicular bisector is:

y - 2.5 = -3(x - 0.5)y = -3x + 4         >> (1)

And the given line is:

2x - 3y + 1 = 0y = 2/3x + 1/3    >> (2)

Solve the system:

-3x + 4 = 2/3x + 1/3-9x + 12 = 2x + 111x = -11x = -1

Find y:

y = -3(-1) + 4 = 3 + 4 = 7

The center is (-1, 7)

Find the radius, the distance from center to one of points on circle

(-1, 7) and (-1, 2) 7 - 2 = 5

The equation of circle is:

(x + 1)² + (y - 7)² = 5²(x + 1)² + (y - 7)² = 25

Hi guys, I really need help, I reckon this is easy for you but I'm low-key disabled and need help with this question so please help me thx. <3

Answers

Answer:

15, 8, 66%, 40

Step-by-step explanation:

Hi! ok so in ogive charts its really about finding the corresponding data points and sometimes it's a lot of estimation so these answers may not be exact but they'll be close.

In the image, you'll see a bunch of lines, basically what youre doing is finding the corresponding frequency of the dollars or vice versa.

question a)

50 dollars or less, so the area of 50 dollars and below that.

from the chart we can see that this lines up to around 15 people.

question b)

now this one is a little bit more challenging, but you can use the same process as you did for the first question. so we can see who spent 100 dollars or less. this value is around 42 (just from looking at the graph)

we know if you didn't spend 100 dollars or less, you must have spent more than that.

so take 50-42=8

around 8 people spent 100 dollars or more.

question c)

basically the same question as the first but more calculations are involved. from the graph we can see around 33 people spent 80 dollars or less. but the question is asking the percentage. so what percent of 50 (people) is 33.

33/50 = 0.66

around 66%

question d)

80th percentile means less than or equal to 80% of the frequencies/the data. so we first need to find what value that is in terms of frequency.

50 times 0.8 = 40

40 people

now just plot that on the graph (sorry i did it wrong in the image)

Answer:

9.103

10. 77

11.60

12. 6.4

13. 20

14. 36

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

180 - (47 + 30) = 103

DEG = 180 - 103 = 77 angles on a straight line equals 180

An equilateral triangle has all 3 sides equal

if the sum of angles in a triangle is 180 degrees, each angle measures 180 / 3 = 60

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

5² + 4² = 41

squareroot of 41 = 6.4

b : √(25² - 15²) = 20

√(60² - 48²) = 36

Answer:

x = 13

Step-by-step explanation:

The difference of two times a number and 5: [tex]2x-5[/tex]

Eight more than a number: [tex]x + 8[/tex]

You can create the following equality with this:

[tex]2x - 5 = x + 8[/tex]

Which is solved as follows:

[tex]2x-5=x+8\\2x-x=8+5\\x=13[/tex]

Answer:X= 13

Step-by-step explanation:

Step 1:

Let the unknown number be x

Such that the difference of two times a number and five is represented mathematically as 2x -5

And  eight more than the number can be expressed as

8 +x

Joining the two expressions to get an equation becomes 2x-5= 8+x

Step 2: Solving for x

2x-5= 8+x

We first find  like terms and solve

2x-x=8+5

We are now left with

x=13 as the answer.
