Answer:

This is a sphere with a center  [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex]  and radius [tex]\dfrac{4 \sqrt{3}}{3}[/tex]

Step-by-step explanation:

Given that: (x,y,z)

where;

d₁ is the distance from the origin = [tex]\sqrt{x^2+y^2+z^2}[/tex]

d₂ is the distance from (2,2,2) = [tex]\sqrt{(x-2)^2+(y-2)^2+(z-2)^2}[/tex]

Also;

d₁ = 2d₂

[tex]\sqrt{x^2 + y^2 +z^2 } = 2 \sqrt{(x-2)^2 +(y-z)^2+(z-2)^2}[/tex]

By squaring both sides;

[tex]x^2 + y^2 +z^2 = 2^2((x-2)^2 +(y-z)^2+(z-2)^2)[/tex]

[tex]x^2 + y^2 +z^2 = 4(x-2)^2 +4(y-z)^2+4(z-2)^2[/tex]

[tex]x^2 + y^2 +z^2 =4(x^2 -2x -2x +4) + 4(y^2 -2y -2y +4) + 4(z^2 -2z-2z+4)[/tex]

[tex]x^2 + y^2 +z^2 =4x^2 -16x +16 + 4y^2 -16y +16 + 4z^2 -16z+16[/tex]

Collect the like terms:

[tex]0 = 4x^2 -x^2 -16x +16 + 4y^2 -y^2 -16y +16 +4z^2 -z^2 -16z +16[/tex]

[tex]0 = 3x^2 -16x +16 + 3y^2 -16y +16 +3z^2 -16z +16[/tex]

Divide both sides by 3

[tex]\dfrac{0}{3} = \dfrac{3x^2 -16x +16}{3} + \dfrac{3y^2 -16y +16 }{3} + \dfrac{ +3z^2 -16z +16}{3}[/tex]

[tex]0 = {x^2 - \dfrac{16x}{3} +\dfrac{16}{3} + {y^2 - \dfrac{16y}{3} +\dfrac{16}{3}+{z^2 - \dfrac{16z}{3} +\dfrac{16}{3}[/tex]

Using the completing the square method;

[tex]3(\dfrac{160}{9}) -16 = {x^2 - \dfrac{16x}{3} +\dfrac{160}{9} + {y^2 - \dfrac{16y}{3} +\dfrac{160}{9}+{z^2 - \dfrac{16z}{3} +\dfrac{160}{9}[/tex]

[tex]\dfrac{16}{3}= (x - \dfrac{8}{3})^2+ (y - \dfrac{8}{3})^2+ (z - \dfrac{8}{3})^2[/tex]

∴

This is a sphere with a center  [tex](\dfrac{8}{3},\dfrac{8}{3},\dfrac{8}{3} )[/tex]  and ;

radius; [tex]\sqrt{\dfrac{16}{3}}[/tex]

From the options, the last one is not reasonable:

Answer:

(3÷5)7

Step-by-step explanation:

As the difference between consecutive terms is the same, the balances form an arithmetic sequence, and:

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms is given by:

[tex]S_n = \frac{n(a_1 + a_n)}{2}[/tex]

From the table, the first term and the common difference are given as follows:

[tex]a_1 = 12000, d = 2018[/tex]

Hence the formula for the balance in the account n years after February 2015 is:

[tex]a_n = 12000 + 2018(n - 1)[/tex]

2032 is 17 years after 2015, hence:

[tex]a_{17} = 12000 + 2018(17 - 1) = 44288[/tex]

The sum is given by:

[tex]S_{17} = \frac{17(12000 + 44288)}{2} = 478,488[/tex]

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

they are congruent

Answer:

42 degrees

Step-by-step explanation:

The two identical lines in sides JK and KL means that the sides are equal. This means that the triangle is an isosceles triangle with the angles J and L being equal. This means that 54+x and 5x-6 are equal. We set this as 54+x = 5x-6. We simplify this to get x = 15. Angle J and L are equal to 69. The angles in a triangle add up to 180, so 69+69 = 138. 180-138 = 42, which is angle K

Answer: the width is 6.25 ft

And the Length is 18.75 ft

Step-by-step explanation:

Length = 3w

Width = w

Perimeter = 3w + 3w + w + w

50 = 3w + 3w + w + w

50 = 8w

w = 6.25

Length = 3w

Length = 3(6.25)

Length = 18.75

Therefore the width is 6.25 ft

And the Length is 18.75 ft

Answer:

Step-by-step explanation:

The absolute difference is estimated as $2.9 million and relative difference is calculated as 26%.

The absolute change refers to the actual increase or decrease from the a reference value to a new value:

absolute difference = new value - reference value

In the given question, the reference value is given as $10.8 million.

The new value is $13.7 million.

absolute difference = 13.7 - 10.8

absolute difference = 2.9

Thus, the absolute value if estimated as $2.9 million.

The absolute difference is described as a fraction of a reference value by the relative difference:

The formula for calculating the relative difference is;

relative difference = (new value - reference value)/reference value

relative difference = absolute difference/reference value

Substituting the values;

relative difference = 2.9/10.8

relative difference = 0.26

relative difference% = 0.26×100%

relative difference = 26%.

Thus the relative difference is estimated as 26%.

Answer:

It costs $1.50 or $1 and 50cents to play one game

Step-by-step explanation:

let x represent cost of games and y represent cost of rides

6x+4y=$22——equation 1

4x+8y=$32——equation 2

Multiply equation 1by 2

2(6x+4y=$22)=12x+8y=$44

Subtract equation 2from 1 to eliminate y

12x-4x+8y-8y=$44-32

8x=$12

x=$12/8=$1.5

Plug in x=1.5 into equation 2

4($1.5)+8y=$32

8y=$32-$6

8y=$26

y=26/8=$3.25

Given:

[tex]\Delta MNO\cong \Delta PQR[/tex]

To find:

The length of QR.

Solution:

We have,

[tex]\Delta MNO\cong \Delta PQR[/tex]

Then, [tex]MN=PQ[/tex]                 (CPCTC)

[tex]10=4x-2[/tex]

[tex]10+2=4x[/tex]

[tex]12=4x[/tex]

Divide both sides by 4.

[tex]\dfrac{12}{4}=x[/tex]

[tex]3=x[/tex]

Similarity,

[tex]MO=PR[/tex]            (CPCTC)

[tex]2y+3=21[/tex]

[tex]2y=21-3[/tex]

[tex]2y=18[/tex]

Divide both sides by 2.

[tex]y=9[/tex]

Now,

[tex]x+y=3+9[/tex]

[tex]x+y=12[/tex]

Therefore, the correct option is d.
