Triangle UVW is dilated with a scale factor of 1∕3 with the center of dilation at the origin. What are the coordinates of the resulting triangle U′V′W′? answers: A) U′ (0, 1), V′ (2, 2), W′ (2, 0) B) U′ (0, 2), V′ (3, 3), W′ (4, 0) C) U′ (0, 1), V′ (3, 3), W′ (2, 0) D) U′ (0, 9), V′ (18, 18), W′ (18, 0)
Answer:
A) U′ (0, 1), V′ (2, 2), W′ (2, 0)
Step-by-step explanation:
The coordinate plane showing Triangle UVW is found online and attached below.
From the graph, the coordinates of the vertices of the triangle are:
U(0,3), V(6,6) and W(6,0)
When you dilate a point (x,y) with a scale factor of 1/3, you obtain: [tex]\left(\dfrac{x}{3}, \dfrac{y}{3}\right)[/tex]
Therefore, applying the dilation [tex](x,y) \rightarrow \left(\dfrac{x}{3}, \dfrac{y}{3}\right)[/tex], we have:
[tex]U(0,3) \rightarrow U'(\frac{0}{3} ,\frac{3}{3})=U'(0 ,1)\\\\V(6,6) \rightarrow V'(\frac{6}{3} ,\frac{6}{3})=V'(2 ,2)\\\\W(6,0) \rightarrow W'(\frac{6}{3} ,\frac{0}{3})=W'(2 ,0)[/tex]
The coordinates of the resulting triangle U′V′W′ are:
U′ (0, 1), V′ (2, 2), W′ (2, 0)
The correct option is A.

Peter wants to flip a fair coin 8 times. He wants to know the probability of getting 3 heads. What is the value of P?
Answer:
7/32
Step-by-step explanation:
Combinators. Your best friend in this scenario.
Basically, using combinations helps you to find the different ways that you could get heads three times out of eight. To do that, just get 8!/(3!5!) (this is a formula, not the exact numbers, per say, you should check that out), which ends up as 56. So there's 56 different ways that Peter can flip a coin eight times and land on heads three times.
Then, you divide that by the total number of possibilities, which in this case is 2^8, since every coin you flip gives you two different options, heads or tails.
Simplifying the fraction gets you 7/32.
Answer:
7/32
Step-by-step explanation:
the probability of getting exactly 3 heads when a coin is flipped 8 times in a row is: 7/32.

[tex]\frac{12}{253}[/tex]
Step-by-step explanation:
So I would start by multiplying all the numbers on
the denominator first ----->
11 x 14 = 154
~~~
14 x 17 = 238
~~~ *BASICALLY: FIND THE COMMON DENOMINATOR*
17 x 20 = 340 (this will be how u add everything at the end)
~~~
20 x 23 = 460
Now your goal is to get all of these numbers to be the same as the denominator so you can add them together at the end (get a common denominator)
**(remember when multipling the top and the bottom numbers, whatever you do to the bottom you must do to the top)**

find the limit of the function algebraically. lim x → 0 -7 + x/x^2
Answer:
[tex]\lim_{x\to 0}\dfrac{-7+x}{x^2}=-\infty[/tex]
Step-by-step explanation:
The given limit problem is
[tex]\lim_{x\to 0}\dfrac{-7+x}{x^2}[/tex]
Left hand limit of the function is
[tex]LHL=\lim_{x\to 0^-}\dfrac{-7+x}{x^2}=\lim_{h\to 0}\dfrac{-7+(0-h)}{(0-h)^2}[/tex]
[tex]LHL=\lim_{h\to 0}\dfrac{-7-h}{h^2}[/tex]
Applying limit, we get
[tex]LHL=-\infty[/tex]
Right hand limit of the function is
[tex]RHL=\lim_{x\to 0^+}\dfrac{-7+x}{x^2}=\lim_{h\to 0}\dfrac{-7+(0+h)}{(0+h)^2}[/tex]
[tex]RHL=\lim_{h\to 0}\dfrac{-7+h}{h^2}[/tex]
Applying limit, we get
[tex]RHL=-\infty[/tex]
Since, LHL=RHL, therefore limit of the function exist at x=0.
Hence, [tex]\lim_{x\to 0}\dfrac{-7+x}{x^2}=-\infty[/tex].
10 tolas gold bought from American market at $ 553 per tola is sold in Nepal at 20% customs duty charge and 13% VAT. At what price should it be sold ?
Answer: $735.49
Step-by-step explanation:
Given, the price of 10 tolas gold bought from American market = $553
Custom duty charge = 20%
VAT = 13%
Custom duty charge = 20% of $553
= 0.20 x 553 [we divide a perecntage to convet it into decimal]
= $110.6
VAT = 13% of $553
= 0.13 x 553
= $71.89
Selling price = Original price +Custom duty charge + VAT
= $553+$110.6+ $71.89
= $735.49
Hence, it should be sold at $735.49 .

Using the digits 1 to 9, at most one time each, fill in the boxes so that the points
make a parallelogram. Mathematically, use parallel line or congruent sides to
explain your answer. if there are calculations, include those in your explanation.
Answer:
(4, 7) (8, 9)
(2, 3) (6, 5)
Step-by-step explanation:
The definition of a parallelogram is a quadrilateral that has two pairs of opposite equal length parallel sides, including equal opposite angle measurements
To simplify the task, we plot the points on a graph paper for the parallelogram ABCD to get the following points;
B (4, 7) A (8, 9)
C (2, 3) D (6, 5)
The length of the opposite sides AB and CD are;
Length AB = √((9 - 7)² + (8 - 4)²) = √20 = 2·√5
Length CD = √((3 - 5)² + (2 - 6)²) = √20 = 2·√5
The length of the opposite sides AC and BD are;
Length AD = √((9 - 5)² + (8 - 6)²) = √20 = 2·√5
Length BC = √((7 - 3)² + (4 - 2)²) = √20 = 2·√5
The slope of segment AB is (9 - 7)/(8 - 4) = 2/4 =1/2
The slope of segment CD is (5 - 3)/(6 - 2) = 2/4 =1/2
Therefore, since the slopes of segments AB and CD are equal, segments AB and CD are parallel
Similarly, we have;
For segment AD, slope = (9 - 5)/8 - 6) = 4/2 = 2
For segment BC, slope = (7 - 3)/4 - 2) = 4/2 = 2
Therefore, the slopes of segments AD and BC are equal, segments AC and BD are parallel.

Answer:
D. Yes The Triangles ARE ≅
Step-by-step explanation:
By definition equilateral triangles have all equal angles and sides. Since they share a side that means one of each triangle's sides are congruent. Using the transitive property (if side a ≅ side b and side b ≅ side c, then side a ≅ side c), you can prove that all other sides are congruent or equal in measure, no matter how you pair them.

"Filipe" was playing with a triangle on a coordinate plane. The triangle's area is 242424 square units. The largest circle he can fit in the triangle is centered at (0,0)(0,0)left parenthesis, 0, comma, 0, right parenthesis and passes through the point (1.2,1.6)(1.2,1.6)left parenthesis, 1, point, 2, comma, 1, point, 6, right parenthesis. Approximately what percentage of the triangle does the circle cover?
Answer:
52.33% is the correct answer.
Step-by-step explanation:
Given that:
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
To find: The percentage of triangle covered by circle.
Solution: To find the required percentage, we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
We can use Distance formula :
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Radius = [tex]\sqrt{(1.2-0)^2+(1.6-0)^2} = \sqrt{1.44+2.56} = \sqrt{4} = 2\ units[/tex]
Now, area of circle is given by the formula:
Area = [tex]\pi r^{2}[/tex]
Area = 3.14 [tex]\times 2^{2}[/tex] = 12.56 sq units
Percentage of Triangle covered:
[tex]\dfrac{Area\ of\ circle}{Area\ of\ triangle}\times 100\\\Rightarrow \dfrac{12.56}{24}\times 100\\\Rightarrow 52.33\%[/tex]
Hence, 52.33% is the correct answer.

Step-by-step explanation:
Given
[tex]f(x) = x^3 - 9x[/tex]
[tex]Interval: (12,6)[/tex]
Required
Determine the average rate of change
Average rate is calculated as thus;
[tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]
In this case; b = 12 and a = 6
Calculating f(12)
[tex]f(12) = 12^3 - 9 * 12[/tex]
[tex]f(12) = 1728 - 108[/tex]
[tex]f(12) = 1620[/tex]
Calculating f(6)
[tex]f(6) = 6^3 - 9 * 6[/tex]
[tex]f(6) = 216 - 54[/tex]
[tex]f(6) = 162[/tex]
Substitute 12 for b and 6 for a in [tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]
[tex]A(x) = \frac{f(12) - f(6)}{12 - 6}[/tex]
Substitute values for f(6) and f(12)
[tex]A(x) = \frac{1620 - 162}{12 - 6}[/tex]

express 3m24cm in kilometers,leaving your answer in standard form
Answer:
0.00324 kilometres
Step-by-step explanation:
Remember:
100 centimeters = 1 meter
1000 meters = 1 kilometer
So first, let's add together the meters and centimeters. To do that, we have to convert the meters to centimeters. That would become 300 centimeters, then you add the 24 centimeters to get 324 centimeters. Then, you convert that to kilometers. You can use a calculator for this, but I'll show you how to do this without a calculator. Since 100 centimeters is one meter, and 1000 meters equals to one kilometer, there would be 5 spaces from 324 to our answer, so you move the invisible decimal point 5 spaces to the left, and you get your answer, which is 0.00324 kilometres!
