Answers

Answer 1

A is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees

A' is (-2,1)

Given :

A triangle ABC is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees.

The rule for reflection over y axis

(x,y) -> (-x,y)

Reflection over x axis is

(x,y) -> (x,-y)

Rotate by 180 degree

(x,y)->(-x,-y)

The point A lies on (-2,1)

Lets find the coordinate of point after reflection over y axis, x axis and rotation by 180 degree using the rules

Reflection over y axis

(-2,1) -> (2,1)

Reflection over y axis

(2,1)-> (2,-1)

Rotate by 180 degrees

(2,-1)-> (-2,1)

So A' is (-2,1)

Answers

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

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.

The table below shows the February balance of a simple interest savings account each year from 2015 to 2021 (7)

Do the balances form an arithmetic or geometric sequence?
What is the d or the r?
Write a formula for the balance in the account n years after February 2015.
Find the sum of the February balances from 2015 to 2032, inclusive.

Answers

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

The common difference is d = 2018.The formula for the balance is: [tex]a_n = 12000 + 2018(n - 1)[/tex]The sum of the balances from 2015 to 2032 is of 478,488.

What is an arithmetic sequence?

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]

The length of a rectangle is 3ft longer than its width.
If the perimeter of the rectangle is 50ft, find its length and width.

Answers

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

Show that the set of points that are twice as far from the origin as they are from (2, 2, 2) is a sphere. Find the center and radius of this sphere.

Answers

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]

Arabella plays 6 games and rides 4 rides for $22.00.
Xavier plays 4 games and rides 8 rides for $32.00.
What is the cost, in dollars and cents, of playing 1 game, to the nearest cent?

Answers

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

Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 19 years?​

Answers

Answer:

The answer to the nearest CENT is A= 11699.69

The amount of money would be $11.4 in the account after 19 years.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A = P(1+r/100)ⁿ

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given that Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously.

p = $4.700

r =4.8%

t = 19 years

A = P(1+r/100)ⁿ

Substitute the values of p,r, and t in the formula,

A = 4.700 (1 + 4.8/100)¹⁹

A = 4.700 (1 + 0.048)¹⁹

A = 4.700 (1.048)¹⁹

A = 11.454133

Rounded to the nearest cent

A = 11.4

Therefore, the amount of money would be $11.4 in the account after 19 years.
