A triangle with the coordinates X(3, 2), Y(5, -1), and Z(-2, 3) is reflected across both the x- and y-axes. The coordinates after both reflections are what

Answers

Answer:

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Step-by-step explanation:

Let be a point [tex](a,b)\in\mathbb{R}^{2}[/tex], reflections across x- and y-axes are represented by the following operations:

x-Axis reflection:

[tex]d = d'[/tex]

[tex]b - 0 = 0 - b'[/tex]

[tex]b' = -b[/tex]

y-Axis reflection:

[tex]d = d'[/tex]

[tex]a - 0 = 0 - a'[/tex]

[tex]a' = -a[/tex]

If we know that [tex]X (x,y) = (3,2)[/tex], [tex]Y(x,y) = (5,-1)[/tex] and [tex]Z (x,y) = (-2, 3)[/tex], the coordinates after both reflections are, respectively:

[tex]X'(x,y) = (-3,-2)[/tex]

[tex]Y' (x,y) = (-5,1)[/tex]

[tex]Z'(x,y) = (2,-3)[/tex]

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Answers

Answer:

Arrange the data in ascending order

1,1,2,3,4,4,4,5,5,5,5,6,6,7,8,11

n=16

position of median = (n+1)/2 = 17/2 = 8.5 th item

8.5 th item is the average of 8 and 9th item

median = (5+5)/2 = 5

Range = largest value - smallest value

           = 11 -1 = 10

position of Q1=  (n+1)/4 = 17/4 = 4.25 th item

Q1 = 4 + 0.25(5th item - 4th item )

    4 + 0.25(4-3)

= 4.25

position of Q3=  (n+1)/4 = 3*17/4 = 12.75 th item

Q1 = 12 + 0.75(13th item - 12th item )

    12 + 0.75(6-6)

= 12

How many protons would make up 9.435 x 10-22 g?

Answers

Answer:

Mass of proton (m) = 1.67×10^(-27) kg

Step-by-step explanation:

Mass of proton (m) = 1.67×10^(-27) kg.

Since, 1 kg = 1000 g

Therefore, m = 1.67x10^(-27+3) g = 1.67x10^(-24) g

Let N no. of protons be present in 1 g. Hence, Nxm = 1 g

So, N = 1 / m = 1 / (1.67x10^(-24))

N = 6x10^(23) (approx.)

Exact mass of proton gives N = 6.022 x 10^(23).

That is a very special no. In fact, it is the Avogadro’s constant used frequently in chemistry. Avogadro’s no. is actually the number of atoms in exactly 12 g of C-12 isotope of carbon. Since, the atomic mass of C-12 is 12 u (unified mass), then again the no. of carbon atoms turn out to be N.

Answers

Answer:

  53°

Step-by-step explanation:

If you translate the 4 N force to the right so its tail is at the tip of the 3 N force, you see these are the legs of a 3-4-5 right triangle. The 4 N force is opposite the angle of interest, and the 3 N force is adjacent. Then the angle of interest, α, has the relation ...

  Tan = Opposite/Adjacent

  tan(α) = 4/3

  α = arctan(4/3) ≈ 53°

The direction of the resultant is 53° clockwise from the horizontal axis.

Answers

Answer:

a = 29

b = 64

c = 87

Step-by-step explanation:

Let the angles be a (smallest), b, and c (largest).

We know that a triangle's angles must add up to 180 degrees, so we can construct the following equations.

a + b + c = 180

c = 3a

b = a +35

With some solving and substitution...

a + (a + 35) + c = 180

2a + c = 145

2a + (3a) = 145

5a = 145

a = 29

and therefore,

b = 29 + 35 = 64

c = 3(29) = 87

Answer:

Let smallest angle be :x

So, the largest angle will be:3x

And the other angle will be :x+35

According to angle sum property of triangle,

x+3x+x+35=180

5x+35=180

5x=180-35

5x=145

x=(145/5)

Therefore, x=29

So, the smallest angle =x=29

The largest angle=3x=87

And the other angle=x+35=64

Explain what the intercepts mean in terms of the context and how to find them.

Answers

Answer:

Intercepts in terms of graphing are considered to be points at which a function crosses an axis.  In the standard x and y graph (the Cartesian coordinate grid), one would find the intercepts by simply plugging in the value of 0 for either the x or the y to find either the y or x intercept respectively.  For example, to find the y-intercept, you want to find (0,y) and to find the x-intercept, you want to find (x,0).

Answers

Answer:

(x - 12)(x - 4)

Step-by-step explanation:

Given

x² - 16x + 48

Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 16)

The factors are - 12 and - 4, since

- 12 × - 4 = + 48 and - 12 - 4 = - 16 , thus

x² - 16x + 48 = (x - 12)(x - 4) ← in factored form

An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

x=36.1

supplementary angle = 143.9 degrees

Step-by-step explanation:

angle: x

supplementary angle: 180-x

x = (180-x)-107.8

2x = 72.2

x = 36.1 degrees

180-x =  143.9 degrees

supplementary angle = 143.9 degrees

x measures 107.8 less than 180-x

x=180-x-107.8

x=72.2-x

Add x to both sides

2x=72.2

Divide both sides by 2

x=36.1
