When point J (-14,6) is rotated 180 degrees around the origin, what is the resulting point J'? a (14,-6) b (-14,6) c (14,6) d (-14,-6)
Answer:
[tex]J' = (14,-6)[/tex]
Step-by-step explanation:
Given
[tex]J = (-14,6)[/tex]
[tex]R_0 = 180^\circ[/tex]
Required
Determine J'
When a point (x,y) is rotated 180 degrees around the origin, the new point is (-x, -y).
So:
[tex]J = (-14,6)[/tex]
[tex]J' = (14,-6)[/tex]
Find the lateral surface area of the following prism: 5 cm 4 cm 5 cm 8 cm 6 cm LSA = [?] cm2 Enter
Answer:
Step-by-step explanation:
I was using 6×8 rectangle as a base of the triangular prism (as shows on the picture.
Let use the definition of a triangular prism and LSA = (5 + 5 + 6) × 8 = 128 cm²
The lateral surface area of the triangular prism is 128 square cm.
What is triangular prism?A triangular Prism is a pentahedron. It is a 3-D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The edges and vertices of the bases are joined with each other via three rectangular sides.
For the given situation,
The sides of the triangle are 5 cm, 6 cm, 5 cm.
The length of the prism = 8 cm
The formula for lateral surface area of triangular prism is
[tex]LSA=(perimeter)(length)[/tex]
On substituting the above values,
⇒ [tex]LSA=(5+6+5)(8)[/tex]
⇒ [tex]LSA=(16)(8)\\[/tex]
⇒ [tex]LSA=128[/tex]
Hence we can conclude that the lateral surface area of the triangular prism is 128 square cm.

One of the games at the carnival was Spin the Pointer, which uses a spinner like the one pictured here. A carnival ticket that costs $1.00 is required to play the game. For each $1.00 ticket, a player spins the pointer once and receives the amount of money indicated in the sector where the pointer lands on the wheel. The spinner has an equal probability of landing in each of the 8 sectors.
a. Let X represent the profit for the player from one play of the game. Complete the table below for the probability distribution of X.
X -$1.00 $0.00 $4.00
P(X)
b. Find the expected value of the profit for the player from one play of the game. You may handwrite your calculations.
Answer:
(a)
[tex]\begin{array}{cccc}{X} & {-\$1.00} & {\$0.00} & {\$4.00} \ \\ {P(X)} & {0.75} & {0.125} & {0.125} & \ \end{array}[/tex]
(b)
[tex]E(x) = -\$0.25[/tex]
Step-by-step explanation:
Given
See attachment for spinner
Solving (a): Complete the table
The amount paid is: $1
From the attached image, we have:
$0 = 6; $1 = 1; $5 = 1
To get the profit, we subtract $1 from the possible outcomes of the spinner.
So, we have:
-$1.00 = 6; $0.00 = 1; $4.00 = 1
The probability of each is then calculated as:
[tex]P(-\$1.00) = \frac{6}{8} = 0.75[/tex]
[tex]P(-\$0.00) = \frac{1}{8} = 0.12[/tex]
[tex]P(-\$4.00) = \frac{1}{8} = 0.12[/tex]
So, the complete table is:
[tex]\begin{array}{cccc}{X} & {-\$1.00} & {\$0.00} & {\$4.00} \ \\ {P(X)} & {0.75} & {0.125} & {0.125} & \ \end{array}[/tex]
Solving (b): The expected profit E(x)
This is calculated as:
[tex]E(x) = \sum x * P(x)[/tex]
[tex]E(x) = -1.00 * 0.75 + 0.00 * 0.125 + 4 * 0.125[/tex]
[tex]E(x) = -\$0.25[/tex]

what is the measure of angle k?
9514 1404 393
Answer:
59°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠N +∠L = 180°
(a +16) +(a -18) = 180
2a = 182 . . . . . . . . . . add 2
a = 91 . . . . . . . . . . . . divide by 2
Then the measure of angle M is ...
∠M = (a+30)° = (91 +30)° = 121°
and angle K is its supplement.
∠K = 180° -121°
∠K = 59°
24. A rectangle has a length of x +5 and a width of 2x-9. Using the formula for the perimeter of a rectangle wrote an expression to represent the perimeter of the rectangle in simplest form
Answer:
Perimeter = 6x-8
Step-by-step explanation:
a=x+5
b=2x-9
Perimeter = 2*(a+b)
Perimeter = 2*(x+5+(2x-9))
Perimeter = 2*(x+5+2x-9)
Perimeter = 2*(3x-4)
Perimeter = 6x-8

What is the length of the altitude of the equilateral triangle below?
Which equation represents a line which is parallel to the y-axis?
X=-4y
Y=x-3
Y=-7
X=-8
Answer:
x = -8
Step-by-step explanation:
If the line is parallel to the y axis, that means it will be a vertical line.
Vertical lines have an equation of x = , because the line will only go through one x value.
They also will not have a slope, because their slope is undefined.
So, the correct answer is x = -8
One month Amy rented 4 movies and 8 video games for a total of 61 dollars. The next month she rented 2 movies and 3 video games for a total of 24 dollars. Find the rental cost for each movie and each video game.
Rental cost for each movie: $?
Rental cost for each video game:$?
Answer:
Rental cost of movie is $6.50 ; Rental cost of video game is $2.25
Step-by-step explanation:
4m + 8v = 61 ........ (1)
2m + 3v = 24 ........ (2)
(1) - 2 × (2)
2v = 13
v = 6.5
2m + 3(6.5) = 24
2m = 24 - 19.5
m = 4.5 ÷ 2 = 2.25
Rental cost for each movie is $6.50
Rental cost for each video game is $2.25

Answer:
a) P = 26 cm
b) A = 36 cm²
Step-by-step explanation:
perimeter is sum of all sides: 6+4+2+3+4+7 = 26
Area can be found by taking entire area, 7x6, then subtracting out the area of the missing piece, 2x3
A = 42 - 6 = 36 cm²
Answer:
Area is 36 and Perimeter is 26
Step-by-step explanation:
solving area:
4x6=24
3x4=12
24+12=36
solving perimeter:
6+4+2+3+4+7= 26
